miles or 6 months, whichever comes first.
Perform all inspections and adjustments
after a thorough steam cleaning.
NOTE: Severe service applications may require
more frequent intervals.

AS-NEEDED LUBRICATION
The following should be performed before putting into
use and then at least once per week or more
frequently as required by operating conditions.
Perform the following steps while in the uncoupled
condition to allow correct application of lubricant.
While lifting up on the fifth wheel top plate, apply
grease to the:
1. ...fittings on the fifth wheel top plate (see
FIGURE 1, ❶) that supply grease to lubricate
the bracket shoe cap and top plate pocket.
(NOTE: LowLube or NoLube top plates do not
have these fittings.)
2. ...fittings ➋ on the side of the shoes (Item 3)
that fill a reservoir that requires approximately
2 pounds of grease.
3. ...fittings ➌ on the base (ends) of the cradle
(Item 14).
4. ...fittings ➍ on the front and back of the cradle
(Item 15).
B. Check the adjustment of the fifth wheel
locks by moving the lock tester fore and

“Fifth Wheel Maintenance Procedures”
XL-FW303-XX, XL-FW308-XX, and
XL-FW354-XX for the particular type of
locking mechanism. If the locks cannot be
properly adjusted due to wear, the fifth
wheel should be repaired or replaced. Your
HOLLAND Distributor has parts, part kits
and fifth wheel top plates available.
C. The trailer kingpin should also be
inspected for wear and damage.
A HOLLAND Kingpin Gauge (TF-0110)
is available to aid this inspection.
3. Kompensator Base Sub-Assembly:
Measure Fore-Aft Movement.
A. Measure the fore and aft movement of the
shoe sub-assembly in the Kompensator
bracket. (See Figure 3.)
Improper adjustment can
cause improper locking of
the mechanism.
