Platform manual closing torsion assist is preset at the factory, however, if it is
necessary to adjust the closing torsion, use the following steps to do so: (See figure
14)
A. Place the platform in the stowed(vertical) position making sure the platform stow
bars are secured in the resting plates on both sides of the liftgate.
B. Remove the .62" diameter retention bolt(A) from the center of the tension adjusting
bracket.
C. Place a .50" square breaker bar in the square hole of the tension adjusting
bracket.
D. Turn breaker bar counterclockwise to relieve the force on the .38" diameter bolt(B)
and remove bolt(B) noting the position of the tension adjusting bracket at the initial
setting.
Step 15
The TVLR above bed models are pre-set to travel 10 inches above bed. Depending
on the bed height it may be possible to obtain up to 16 inches above bed. Refer to
tables 1 and 2. To do this some of the lift chain must be removed. This amount is the
same as the additional travel desired. The platform must be completely lowered to the
ground and the cylinder housing cover removed. Remove the jam nuts and tension
rods attached to the chain and cut off the required amount from each chain. Push the
cylinder rod in and reassemble the tension rods and replace cover. Raise the platform
and check dimensions and adjust as necessary.
