StowMaster bushing and Autowlok
™
assembly
Figure 1
Figure 2
Note: to replace an Autowlok button only, it is not necessary to disassemble the tow bar. See “To replace an Autowlok
button” on page three.
CAUTION
If both Autowlok assemblies will be replaced, work
on one tow bar arm at a time. The inner arms are not
interchangeable. If the inner arms are not replaced
correctly, the tow bar will not center the towed vehicle
behind the motorhome, which may cause severe tire
damage, as well as other consequential, non-warranty
damage to the towed vehicle.
To replace an entire Autowlok assembly…
1.
Disconnect one of the inner arms (Figure 1) — first, re-
move the 3/8" safety bolt and nut (Figure 1) on the outer
arm (Figure 1). Then, drill out the 1/8" pop rivets (one on
each side — Figure 1) holding the rear bushing.
CAUTION
After drilling out the pop rivets, clean the interior
of the outer arm to remove any metal shavings from
the interior of the outer arm. The shavings may impair
the operation of the sliding arms, as well as score or
otherwise damage the plastic bushings.
2.
Hold a piece of cloth over the end of the outer arm.
Press the Autowlok button (Figure 2) down and slide the
inner arm out of the outer arm.
CAUTION
The spring inside the Autowlok assembly is under
pressure. It will eject a pin when the spring and pin
clear the outer arm, and the pressure is released.
To avoid injury, hold a cloth over the end of the outer
arm and stand to one side, clear of the pin and spring,
as the Autowlok assembly clears the outer arm.
3.
Discard the old spring and pin (Figure 2).
4.
If the button stem (Figure 2) will not be replaced, proceed
to step 5.
If the button stem will be replaced — first, insert the new
button stem flat side up (Figure 3), into the opening near the
inner front bushing. Then, slide the inner arm into the outer
arm until the top of the button stem is visible through the hole
in the outer arm.
