Clean the exterior of the gear with solvent. If necessary, drain off excess
hydraulic fluid.
Handle the parts carefully to avoid nicks, burrs, scratches and dirt. Do
not use solvent on seals.
Inspection
Inspect the input shaft bearing. Check the fit of the bearing on the input
shaft. Replace the bearing if necessary.
Inspect the valve housing for wear, scoring or burrs.
Check the fluid passages for obstruction or leakage.
Inspect the gear housing for cracks and stripped threads and the mating
surfaces for burrs. Inspect the piston bore for scoring or wear, If necessary,
replace the housing.
Ensure input shaft and bearings rotate freely.
Check the input shaft for freedom of movement in the sleeve. If movement is
impaired, replace the valve assembly.
Inspect the piston rack-and-pinion shaft teeth for nicks and burrs.
