3. Grease the yoke tips, locks, and the release
handle and spring; see
Fig. 12 . Grease the
mounting bracket supports through the grease
fittings. A “low temp” grade grease rated for
-30°F (-34°C) or lower such as Cato Oil and
Grease #5213, Craftsman Chemical Co. #LTF 2,
Mystic LP-200, or equivalent is recommended.
Castloc II and Simplex Series
Use a chassis or multipurpose grease to lubricate the
two grease fittings located on either side of the fifth
wheel top plate. Lubricate the two grease fittings lo-
cated in the grease grooves on the fifth wheel top
plate. Lubricate the two grease fittings located below
the top plate mounting pins. Lubricate the lock
mechanism.
Once the fifth wheel’s moving parts are lubricated,
apply a heavy coat of grease to the top plate, either
through the grease fittings located on the underside
of the top plate, or by direct application. On slide-
mount applications, lubricate the slider lock pockets
and the slider bracket.
Jost
Lubricate the kingpin lock using a hand pump grease
gun through the grease zerk on the skirt of the fifth
wheel; see
Fig. 10 . Apply a light oil to all moving
parts. For sliding fifth wheels spray diesel fuel on the
slide path of the base plate.
NOTICE
Do not use a power grease gun. The pressure will
damage the lube line.
If the fifth wheel is not equipped with low-lube plates,
apply a lithium-based grease with extreme pressure
(EP) additive to the trailer contact surface of the fifth
wheel.
NOTE: If the fifth wheel is equipped with low-lube
plates, the top plate only requires lubrication at the
new product break-in stage. The low-lube plates re-
quire no further lubrication.
