surface of the fifth wheel.

fifth wheel. Failure to follow all of the important maintenance procedures contained
in these instructions may result in a hazardous condition or cause a hazardous condition to develop.
All maintenance must be performed by a qualified person using proper tools and safe procedures.

3. Grease the support bracket pockets through the
grease fittings on the front of the fifth wheel
bracket pockets (lift up slightly on the fifth
wheel plate when applying grease).
4. For fifth wheels with sliding brackets:
Release and slide fore and aft to assure entire
mechanism functions properly. Apply an aerosol
spray lubricant or soap to the slide path. Apply
Never-Seez ™ to the plunger and its moving parts.
Reposition and lock sliding mechanism.
5. Inspect the release handle. If your fifth wheel is
a RIGHT HAND (curb side) release, apply grease
along the release handle where it contacts the
handle spring (see Figure 1a). If you have a LEFT
HAND (driver side) release handle with a sliding
spring, as shown in Figure 1b, apply grease
along the release handle where it contacts the
handle spring. Lubrication is NOT required for
LEFT HAND (driver side) release handles that
HAVE a fixed spring (see Figure 1c).
6. Check the operation by locking and unlocking
using a Holland TF-TLN-5001 Lock Adjustment
Tool. Verify that the fifth wheel is completely
closed, as shown in Figure 3A on page 14.
