Reassembly
Check all mating surfaces. Replace any parts that have scratches or
burrs that could cause leakage or damage. Clean all metal parts in
clean solvent. Blow dry with air. Do not wipe parts with cloth or paper
towel, lint or other matter can get into the hydraulic system and cause
damage. Check around the key slot and chamfered area of the shaft
for burrs, nicks or sharp edges that can damage the seals when
reassembling. Remove nicks or burrs with a hard smooth stone (such
as an Arkansas stone). Do not try to file or grind motor parts.
Note: Lubricate all seals with petroleum jelly such as Vaseline. Use
new seals when reassembling the motor. Refer to parts list (No. 6-
125) for proper seal kit number.
Important: Do not stretch seals before installing. Cleanliness is
extremely important in the successful application of Loctite. Use the
following procedures to properly clean all parts.
A. Wash the housing with non-petroleum base solvent to remove oil,
grease and debris. Petroleum base solvents may leave residue
detrimental to successful Loctiting. Pay particular attention to 4
tapped holes on the flange end.
Note: Fully cured Loctite resists most solvents, oils, gasoline,
kerosene, and is not affected by cleaning operations.
B. Blow dry with compressed air. Clean and dry the tapped holes.
Note: It is not necessary to remove the cured Loctite that is securely
bonded in the tapped holes; however any loose particles of cured
Loctite should be removed.
C. Wire brush the screw threads to remove cured Loctite and other
debris. Discard any screws that have damaged threads or a corroded,
damaged, or rounded head.
D. Wash the screws with non-petroleum base solvent. Blow dry with
compressed air jet.
19 If you removed check valves, or plug(s), replace seal(s). Lubricate
new seal(s). Install on check valves, or plug(s). Carefully push check
valves, or plug(s), in housing until flush with housing face. Do not
damage seal(s).
20 Lubricate output shaft with clean hydraulic oil, then install shaft in
housing.
Important: Do not permit oil to get into the 4 tapped holes.
Note: To help with timing procedures, a timing dot is machined on
output shaft, see figures 18 and 19.
21 Install needle thrust bearing then bearing race on shaft. Pull shaft
partially out of housing, push all three parts in housing together. The
bearing race must rotate freely when in position.
