FIGURE 13 – OIL SEAL WEAR SLEEVE INSTALLATION TOOL
To reassemble the jackshaft in the pump, it is
necessary to reverse procedure of removal. The teeth
of the pinion can mesh in only one direction, therefore,
the jackshaft is not interchangeable end for end in the
pump unless gear and eccentric assembly is also
reversed. Reversal of the complete gearset is
permissible after gear or pinion teeth become badly
worn. Since gear is not on centerline of the frame, it is
necessary to move the oil pump and filter from original
position to the opposite side of the frame and repipe as
required.
Required direction of rotation of the pump provides
that inner ends or apex of gear and pinion teeth lead.
This means that when viewing from the hood opening,
the inner ends of the gear teeth point upward toward
the jackshaft and the inner ends of the pinion teeth
point toward the gear. Gears may be reversed, but
direction of rotation of the pump MUST NOT BE
REVERSED. See paragraph “Lube Oil Pump” on the
following page. Pump should be run in the direction
shown on sectional view and indicated by arrow on
outline print and frame. Apex of teeth will follow after
gearset has been reversed.
After jackshaft is in place with the pinion in mesh with
the gear, install the bearing housings with the outer
bearing race and roller assemblies in them. Be careful
to keep dirt from the bearings during assembly. The
housing is to be started on the bearing and in the bore
of the frame and lightly driven in. Be sure the gasket is
on the housing. Long threaded studs may be used to
pull the housing into the frame bore. It is well to work
both housings at the same time after they have been
well started over the bearing inner race. This will
minimize end thrust on the gear teeth.
Before assembling bearing plates into the frame, the
bearing oil troughs should be installed. The bearing
housing can be rotated in the frame, making it easy to
