6. Remove mounting flange (2) from motor housing.
7. Carefully remove exclusion seal (1), pressure seal
(4) and backup ring (3) from mounting flange (2). A
seal removal tool may be fabricated by bending

driver, refer to Figure 21928. Be careful to not dam-
age the mounting flange shaft bore.
Steer Motor Assembly
Check all mating surfaces. Replace any parts with
scratches or burrs that could cause leakage. Wash all
metal parts in clean solvent. Blow dry with low pressure
air. Do not wipe parts dry with paper towels or cloth.
Lint in a hydraulic system will cause damage. Check
spline and chamfered area of output shaft; remove any
nicks, burrs, or sharp edges that could damage shaft
seals during assembly.
Always use new seals when assembling hydraulic mo-
tors. Lubricate new seals with clean petroleum jelly.
Also, lubricate machined surfaces and bearings with
clean hydraulic fluid.
1. Remove all thread locking adhesive from mounting
flange screws and their threaded holes. Threads
must be clean and dry before applying new thread
locking adhesive.
2. Refer to Figure 21926. Lubricate and install output
shaft (3), thrust needle bearing (2) and bearing
race (1) into housing. Do not allow oil to enter cap
screw threaded holes.
3. Refer to Figure 21927 for correct seal orientation.
Lubricate exclusion seal (1) and install in mounting
flange (2).
