Installation and Operation of the TS3 Air Ride Hitch

 

NOTE: Every hitch is shipped with a handle extension kit used to operate the hitch locking mechanism from outside of the truck body. This kit consists of an extension handle and an extension hook. Make sure your installer has given it to you.

Standard Install: This hitch is made to install in Reese Rails or equivalent. If this is a retrofit, you need to remove your existing hitch now. Loosen the 2 bolts in each corner of the TS3 hitch. Set the TS3 in place in the appropriate rectangular holes in the Reese Rails. Now insert the 4 pins through the bottom rail in each corner making sure to use the retaining clips. Tighten the ½" bolts (total of 8) to 150 foot pounds of torque. Even if your hitch dropped right in, the bolts still need to be tightened as they are only hand tightened at the factory. You are done with the standard install.

2" or 3" option: if you have this option, your hitch will have a 2" or 3" spacer between the Reese Rails and the base of the TS3. Follow procedure as above making sure to tighten all bolts securely to 150 foot pounds of torque.

Air Compressor & Control Assembly option: The TS3 comes standard with a Schrader valve to inflate the hitch. If you have opted for the air control assembly in the cab, there is a little more work to do. The air compressor should already be mounted in the base of the hitch. If yours has not been mounted, now is the time to do so with the 4 bolts supplied. Mount your electric gauge assembly in the cab somewhere convenient to use later, preferably it should be reached from outside the cab. Find a 12 volt source of current and bring it to one side of the switch. The other side of the switch will go to the compressor mounted in the hitch. The black wire from the compressor is the ground. This needs to go to a secure vehicle ground that will not corrode later. Run the ¼" line supplied from the tee at the back of the gauge to the air line tee in the hitch. You will be able to monitor hitch pressure from the cab now. With this assembly, you can deflate the hitch from the cab by pressing in on the air button.

Air Compressor & Switch option: Your Schrader valve is still on the hitch assembly, but now you have a push button switch that you can control the compressor. Everything has been already mounted for you. You will inflate using the push button and deflate the hitch by using the Schrader valve.

Paddle control valve: if your truck has on onboard supply of air, the following will apply. You can mount the paddle control valve under your dash or in the bed wherever it works best for you. The paddle control valve comes with 30’ of ¼" air line. The supply side of the switch will need to go to your air tank or a pressurized line. You can use the tee supplied and cut the pressurized line inserting the tee and running the air line to your valve. The delivery side of the valve goes to the TS3. Pull the adapter from the back of the Schrader valve and that should be a ¼" fitting that you can use a quick coupler and hook the air line to the hitch.

Operation of the TS3 Air Ride Hitch

Hooking up your trailer

(Before continuing, read "Auto Lock Position" close to the end)

Step 1) Make sure the unlatching handle of the hitch is in the "auto lock" position. The handle will be at a 90-degree angle from the centerline of the hitch or in the nine o’clock setting. It will be facing straight at you if you are standing on the left side of the truck facing the hitch.

Step 2) Back your truck to the trailer until the kingpin just enters the "V" of the hitch. If you have the standard hitch without remote air control, lower your trailer to where it makes good contact with the fifth wheel. If you have the remote air fill, raise the hitch until it comes in contact with the kingpin plate. Put a small amount of air pressure (10#) on the kingpin plate to assure that you are in the correct position for proper lockup. We want good contact so that we do not try to "high hitch", yet we do not want to pick the trailer off the ground.

Step 3) Now, back into the kingpin. The latching handle will move toward the rear of the hitch when it is locked in position. The spring loaded detent pin will move into position in front of the steel sliding locking bar to secure the locking mechanism. This is the eight o’clock setting. On the right side of the hitch there is a hole located in the channel that the steel bar slides in. You may install a padlock in it to prevent anybody from unlocking the hitch assembly. Do not go behind the truck to try and examine the jaw position. There are 2 issues here, if you are not locked, you do not want the trailer to fall on you. Second, just because the jaws are wrapped around the pin does not mean that they are latched. The locking bar must come back to keep the jaws closed.

CAUTION: ALWAYS TRY TO MOVE THE LOCKING HANDLE FORWARD AFTER HOOKING UP TO YOUR TRAILER TO MAKE SURE YOU ARE LOCKED IN POSITION!! If you cannot move the handle past the detent pin you are locked and ready for travel.

If you experience difficulty with the hitch jaws locking, check the condition of the trailer pin. It must be free from all burrs and paint buildup. The anti-friction pad must be tight against the pin box. We have also seen dirt and grease buildup on the pin from using a hitch with a thinner locking mechanism than we use. Any of the above conditions may cause the locking jaws not to lock.

Step 4) Raise the legs of the trailer and then add the correct amount of air to the air springs. On the left rear of the hitch, you will see a white line on the traveling arm. As the hitch goes up, the white line will just become visible over the edge of the hitch. At this position, you are at the minimum operating height of ¾". Start here and adjust to get the ride that you desire. If the hitch is making a "clunking" sound as it bottoms out, you know that you need to add more air. In our case, usually less is better. Look at the pressure gauge to see what the pressure is and from then on you can hook up and inflate the air bellows to that same pressure. The pressure on the gauge is usually between 40 and 90 pounds depending on your pin weight. If you are using the Schrader valve, you should be ready to go next time also.

Disconnecting from your trailer

After you have located your trailer in its final position and put in your wheel chocks, lower your trailer legs and apply enough downward pressure to pick up the trailer a little bit. At this time unlock the jaws on the Holland 5th wheel hitch. To do this you must first pull the spring loaded detent pin located on the left front side of the hitch, and while holding the pin move the unlatching handle forward, (towards the front of the truck) as far as it will go. This will be the ten o’clock setting. At this position, the detent pin will engage a hole in the sliding steel bar locking it open. Usually the jaws will open, however, if there is pressure against the kingpin, the jaws may not open, but the hitch is unlocked and as soon as you move your truck a fraction of an inch the jaws will open.

Schrader valve) Now raise the trailer until the upward stops are reached. OR

Air control unit) Next, remove ALL of the air from the air springs of your hitch. Both units) If you do not perform one of the above functions, the hitch will come upward with great force as you pull away. This is not a good thing. After you have relieved pressure from the hitch, you may now drive away from your trailer after disconnecting your cables.

Auto Lock Position

After you have pulled away from your trailer you may move the unlatching handle far enough forward to release the tension that is against the detent pin and then pull the pin and allow the unlatching handle to move rearward. This operation will allow the detent pin to rest against the sliding steel bar and be in the nine o’clock setting. This action puts the hitch in the "auto lock" position. Now when you back into the trailer kingpin, the jaws will automatically close.

If you elected not to do the above step, and instead leave the sliding bar locked open, you must manually lock the assembly. After backing into your trailer kingpin, manually pull the detent pin out of the hole so the steel bar will move rearward securing the locking jaws in place. If you do not do this, the trailer will separate from the hitch when you move forward with your truck. This is certainly not a good thing.

If you have any trouble you can call Steve Dobbs at 270-779-9182.

Installation & Operating Instructions for TSLB2H

Installation & Operating Instructions for TSLB-*H

NOTE: Every hitch is shipped with a handle extension kit used to operate the hitch locking mechanism from outside of the truck body. This kit consists of an extension handle and an extension hook. Make sure your installer has given it to you.
Center the TrailerSaver Air Suspension Hitch between the truck’s frame members. Some facilities recommend that the center of the hitch head be located at the centerline of the truck axle.  Several installation facilities have located the center of the hitch head behind the centerline of the axle with no adverse results. Each installation is most probably unique to each truck configuration so the installation may vary for each job.  This information publication is only a recommendation for the proper installation method for the TrailerSaver Air Suspension Hitch.
The base of the hitch must be bolted to the truck’s frame members. This can be accomplished in a number of ways. You may install a ½" thick steel plate over the complete area of the hitch base which, extends to both frame members and then bolt the hitch to it. You may install two 3/4" x 6" steel plates which extend to both frame members and then attach the hitch to them using the pre-drilled holes in the base of the hitch. When fastening the cross members to the frame, be sure to fasten them to the face of the frame.  It will be necessary to install vertical members to the face of the frame and then bolt the cross members to them.  Grade 5 or grade 8 bolts of ½" diameter must be used for all bolting configurations.  On model TSLB-1H you must use all (8 holes) of the predrilled holes in the hitch base.   On model TSLB-2H, you must use at least 4 bolts on each side of the hitch making sure to use the 2 front most holes or 4 bolts laterally across the front of the hitch and 2 bolts at the rear of the hitch. Consult with your installer for more ways to fasten your new hitch to your truck. 
Packaged with the hitch is a coil of ¼" tubing, (1) control w/gauge (as shown above), and (1) ¼" push-on TEE.  Locate an air supply from the truck, cut the line and install the ¼" TEE between the cut ends. Install one end of the ¼" tubing into the TEE and the other end onto the control fitting marked "From truck air supply".  On the other fitting marked "To air Bellows", attach the tubing. Now route it back to the hitch and attach to the TEE that has been installed at the factory.  Be sure to secure the tubing so that it doesn’t come in contact with members that may rub a hole in it.  The control may be mounted any place convenient for you, however, it needs to be protected from the weather. 

Operation of the TrailerSaver Air Suspension Hitch

The minimum operating height for the Trailer Saver Air Suspension Hitch is ¾" from the lower most or parked position.   After connecting to your trailer add air to the air bellows until the hitch raises to the proper height.   Look at the pressure gauge to see what the pressure is and from then on you can hook up and inflate the air bellows to that same pressure.  This pressure usually will be from 40 to 90 pounds.

Hooking up your trailer (before continuing, read "Auto Lock Position" on back of this page)

Step 1)  Make sure the unlatching handle of the hitch is in the "auto lock" position.  The handle will be at a 90-degree angle from the centerline of the hitch or nine o’clock setting.  It will be facing straight at you if you are standing on the left side of the truck facing the hitch.

Step 2) Back your truck to the trailer until the kingpin just enters the "V" of the hitch. At this time raise the hitch until it comes in contact with the kingpin plate.  Put a small amount of pressure (10-15#) on the kingpin plate to assure that you are in the correct position for proper lockup.

Step 3) Now, back into the kingpin. The latching handle will move toward the rear of the hitch when it is locked in position.  This is the eight o’clock setting. The spring loaded detent pin will move into position in front of the steel sliding locking bar to secure the locking mechanism.  On the right side of the hitch there is a hole located in the channel that the steel bar slides in.  You may install a padlock in it to prevent anybody from unlocking the hitch assembly.

Any of the above conditions may cause the locking jaws not to lock.

Step 4) Raise the legs of the trailer and then add the correct amount of air to the air springs.   There are two white marks at the left rear of the hitch. When these are aligned, you are at the minimum operating level of ¾". Start here and adjust to get the ride that you desire. The pressure on the gauge is usually between 40 and 90 Pounds depending on your pin weight.

Disconnecting from you trailer

After you have located your trailer in its final position and put in you wheel chocks, lower your trailer legs and apply a small amount of downward pressure.  At this time unlock the jaws on the Holland 5th wheel hitch.

If you elected not to do the above step, and instead leave the sliding bar locked open, you must manually lock the assembly. After backing into your trailer kingpin, manually pull the detent pin out of the hole so the steel bar will move rearward securing the locking jaws in place.  If you do not do manually lock the sliding bar, the trailer will separate from the hitch when you move forward with your truck. This is certainly not a good thing.

Lubrication is necessary on the Holland head as well as the axis pins on the TrailerSaver Air Suspension Hitch.  On the front underside of the hitch head is a spring that needs to be lubricated with WD-40 or equivalent. This spring slides forward and aft when the head tilts front to back. It is necessary to lubricate the axis pins located on the front of the hitch with a grease gun at 4,000-mile increments.  The moving parts on the Holland hitch head may be lubricated with WD-40 or equivalent as needed.  It is recommended that you inspect the axis pins and hitch-pivoting pin annually to check for wear.

7.5K Lift Kit Installation Instructions

To aid in installation, it is best to air up the hitch, and put a block in the air bag area to keep the hitch raised. 

With the hitch “blocked”, release all of the air from the hitch.  We need to remove the head assembly to do some drilling.  This is done by removing the 1” by 10” bolt where the head assembly pivots.  This is also a good time to inspect the bolt for excessive wear.   

Now remove the shock absorber from inside the cavity of the hitch.  With this kit installed, the shock absorber is no longer needed and may be discarded.  The supply air line usually comes in from the bottom.  Wherever it is, disconnect the air line from the tee. Look at the drawing (below) for the position of the (2) 7/16” holes that will need to be drilled in the swing arm.  In the photo, you can see the holes just down from the shock mount. 

Now insert the 7.5k assembly in the cavity.  Line up the ½” hole in the kit with the ½” hole in the base plate.  Using the bracket as a template, drill 5/16” holes through the bed through the pre-drilled holes. There will be a DVI control already installed at the air line fitting on the new air spring, do nothing with this.  Cut one of the pre-existing air lines and splice in the new air bag with the supplied tee.  Next loosely insert the 3/8” bolts (included) into the top of the air bag.  Using 5/16” bolts that you provide, insert these through the base of the kit and truck body, and tighten securely.  Also, the 3/8” bolts attaching the air bag to the swing arm of the hitch are now ready to be tightened. 

It is now time to set the head assembly in place.  Next, apply about 20 pounds of air to the hitch and check for leaks with a soap solution.  Remove the block that you used at the rear of the hitch.  You are now ready for normal use. 

If you have any questions, feel free to call Steve at 270-779-9182

INSTALLATION PROCEDURES

DVI RIDE STABILIZERS ON AIR-RIDE HITCH

DVI Ride Stabilizers come with a short piece of tubing installed in one end. Remove the tubing from the air fitting that is on your air spring by pulling the collar that is on the fitting towards the fitting while at the same time pulling the tubing out of the fitting. Install the Ride Stabilizer into the air fitting by pushing the tubing into the fitting until it bottoms out and then re-install the airline into the open end of the Ride Stabilizer. You will be able to run with less air pressure with the Ride Stabilizers installed.

We can also run at a lower operating height. We are now recommending running with ¾" of air in the bags as a starting point. You can tell if you do not have enough air in the bags if the hitch bottoms out in rough terrain.

We were able to drop running pressure from 75 lbs to 65 lbs. It is a bit of a trial and error until you reach your optimum operating pressure for the ride that you desire.

INSTALLATION PROCEDURES

FOR DVI RIDE STABILIZERS ON AIR RIDE SEATS

The DVI Ride Stabilizers for air seats come with a short piece of tubing installed in one end. Remove the tubing from the air fitting that is on your air spring by pulling the collar that is on the fitting towards the fitting while at the same time pulling the tubing out of the fitting. Install the Ride Stabilizer with the short piece of tubing into the air fitting by pushing the tubing into the fitting until it bottoms out and then re-install the air line into the open end of the Ride Stabilizer.

If your seats do not have the quick disconnect fitting they will have a barbed fitting installed. If this is the case you will need to cut the tubing 3/4" from the end of the barb fitting. Remove the short piece of tubing that came installed in your stabilizer and install the DVI Ride Stabilizer onto the cut tubing and install the other end of the tubing into the other end of the stabilizer. These units are non-directional.

These units come in sizes 3,4,5,6, and 7. The lower the number, the tighter the control. For example, if you are medium height and light weight, the "7" will give you a nice bit of control. The "4" will ride way too hard. The shorter that you are, the tighter control that you will need. And, the heavier that you are, the tighter the control that you will need.

These devices will enable you to run with the seat positioned lower without bottoming out. For real tall people, we also see less tossing of your head into the roof.
