Steering Gear: Initial Inspection and Diagnostic Overview
CLEANING
CAUTION: Do not clean, wash or soak in the cleaning solvent,
Disassembly and assembly of the steering gear and subassemblies must be made on a clean workbench. As in repairing any hydraulically operated
unit, cleanliness is of utmost importance. The bench, tools, and parts must be kept clean at all times. Thoroughly clean the exterior of the unit with a
suitable solvent and, when necessary, drain as much of the hydraulic fluid (or gear grease) as possible. Handle all parts very carefully to avoid nicks,
burrs, scratches and dirt, which could make the parts unfit for use.
INSPECTION
1. Check input shaft bearing for damage. Replace if necessary.
2. Inspect the valve housing for scoring or burrs.
3. Inspect the tube seats (if equipped) in the pressure and return ports in the housing. If nicks, etc., are present replace tube seats.
4. Check all fluid passages for obstruction or leakage.
5. Inspect the steering gear housing for cracks, stripped threads, and mating surfaces for burrs. Inspect the piston bore of the housing for scoring.
Check roller bearing for damage. If necessary, replace the housing.
6. Check the input shaft bearing after installation to be sure that it rotates without binding or roughness.
7. Check the pinion and rack teeth or sector shaft teeth and piston rack teeth for nicks and burrs.
