5. Handle Timing and Adjustment
When replacing the handle weldment (TB-7378-HDL) the handle must be properly aligned on the
actuating screw (TB-7378-TL). The handle should go from slightly past parallel with the top of the
head at both the open and closed position.
To properly rack the hand on the screw, place the slide lock into vice with the wide side parallel to
the ground. Place the handle barrel on the thread so that the first
thread catches near the 1” o’clock
position, when facing the nut on the handle. Rotate the handle until the barrel of the handle contact
the block. The handle should be near parallel and ideally slight below.
Starting Position
Proper Finishing Position
The latch must easily close over the handle when operating.
When replacing the handle or thread check that the motion of the handle is easy throughout the
entire range of motion. The rear bearing block alignment is critical to the proper function of the
towbar. While tightening the screws holding the rear bearing block, continuously move the handle
throughout its entire range of motion to verify alignment. If the handle catches or becomes difficult
at any point, loosen the rear block and start over.
