cradles during assembly.
JAW PIN GREASE FITTINGS

located in each jaw. These grease fittings are visible from
each side of the Q24 5th wheel.

MAINTENANCE SCHEDULE
IMPORTANT: Torque the four pilot bolts to 100 foot lbs.
Re-torque after initial 500 miles and every 1,000 miles
thereafter and prior to each individual use.
Lubricate before each individual use and every 1,000 miles
thereafter. Black graphite grease is recommended for the jaw,
pins and the lower bearing assembly jaw. High-pressure wheel
bearing grease is preferred for the skid plate. NOTE: In severe
cold temperatures a lighter grease, such as white lithium, may
be substituted for the jaw pins and the lower bearing assembly
jaw. This will ensure that all mechanisms work as designed.
LOWER BEARING
GREASE FITTING
Lower bearing
grease fitting
The lower bearing assembly is supplied with grease
through the grease fitting centered in the cast base plate.
