Universal Joint
The engine drive universal is located and accessed by
removing the operators seat, and removing the service
access cover. The universal joint should be serviced every
50 hours. Check the universal joint for wear and lubricate
with a standard grade of multi purpose grease.
To Service the U- Joint:
1 Remove any attachment, raise the boom arms,
engage the boom supports, engage the parking brake and
shut off the engine. Remove the ignition key.
2 Remove the seat assembly. Be sure to disconnect the
electrical plug on the seat switch, left hand
side.(fig.C5017)
3 Remove the service access panel, located below the
battery compartment cover, by removing the 2 bolts and
pushing rearward on the top part of the cover, lifting and
pulling forward from the bottom.(fig. C5648) Removal
of the battery access panel will make servecing the u-joint
easier.
4 Grasp the U- Joint assembly with your hands and
rotate the joint left and right, forward and back to check
U- Joint wear.
5 Check the condition of the splined yoke and spline
on the hydrostatic pump input shaft.
4 Rotate the U- Joint if necessary to locate the grease
fittings on the U- Joint crosses. Apply 2 ~ 3 pumps of
multi purpose grease to each U- Joint cross.
NOTE: Remove the U- Joint assembly from the loader to
replace worn u- joint crosses. (fig. C2789) The crosses
are retained by internal snap ring clips.
To remove the u-joint assembly.
1 Remove the 5 bolts that attach the assembly’s drive
plate to the engine flywheel. (fig. C5211)
2 Slide the u-joint ahead on the pump spline while sup-
porting the drive plate. Lift the drive plate away from the
engine folding the u-joint. Slide the yoke off of the pump
spline.
Before installing U-joint assembly, check that the fly-
wheel surface and the matinng surface of the drive
plate are clean and smooth. No nicks, burrs, paint,
etc.
To install the u-joint, grease the pump spline, then reverse
the previous steps. Torque the drive plate bolts to
20ft/lbs. (27.2 Nm)
