The M-100 series Sheppard steering gear requires no maintenance. Using
hydraulic pressure to assist rotating the output shaft of the steering gear provides
power steering. Located at the end of the input shaft of the steering gear is poppet
valve and worm drive. The poppet valve directs the hydraulic fluid pressure to a
type of spool. There are worm drive threads in the center of the spool. When in the
center position, pressurized hydraulic fluid bypasses the spool. When a turn is
made, the poppet valve shifts to one direction or the other, directing the hydraulic
pressure to one side of the spool depending on turning direction. The hydraulic
fluid is then cooled before returning to the reservoir. Inspect for signs of leakage
when performing fluid level checks. Changing the hydraulic filter at regular
intervals will help ensure trouble free operation.
The steering wheel connects to the steering box using a drive shaft. Service the
steering drive shaft universal joints and slip yoke every 30,000 miles or annually.
Remove the steering column cover to access the upper universal joint and slip
yoke. The lower universal joint is accessed from underneath in the generator
compartment behind the front electrical box.
Greasing the Drive Shaft Universal Joints:
1. Check the drive shaft for looseness. If loose or worn, repair the drive
shaft as necessary.
2. Apply the specified grease at the grease fitting on the universal joint.
Apply new grease until the new grease purges from all the seals.
3. If the new grease does not purge from the seals, disassemble and
clean the joint or replace the universal joint. Do not lose any of the
needle bearings.
Greasing the Drive Shaft Slip Yoke and Splines:
1. Check the drive shaft for looseness. If loose or worn, repair the drive
shaft as necessary.
2. With finger, cover the rear air hole so grease flows to the front seal.
Apply the specified grease at the grease fitting on the slip yoke. Apply
grease until new grease purges and forces finger away from the air
hole in the end of the slip yoke. Greasing interval is yearly or every
30,000 miles.
