14. 2 Inspect drive shaft bearing for roughness pitting of rollers and excessive end play Replace if defective If the bearing needs to be replaced the bearing race also requires replace ment 3 Inspect housing mounting flange for nicks and burrs Re move minor nicks and burrs with an India stone Also check the housing for damaged or stripped threads If any thread is damaged replace the housing 4 Check remaining pump parts for excessive wear damaged threads burrs cracks and erosion Replace any part that is in questionable condition The following should be checked regularly 1 All hydraulic connections must be kept tight A loose con nection in a pressure line will permit the fluid to leak out If the fluid level becomes so low as to uncover the inlet pipe opening in the reservoir extensive damage to the pump can result In suction or return lines loose connections permit air to be drawn into the system resulting in noisy and or erratic operation 2 Clean fluid is the best insurance for long service life There fore the reservoir should be checked periodically for dirt or other contaminants If the fluid becomes contaminated the system should be drained and the reservoir cleaned before new fluid is added 3 Filter elements also should be checked and replaced periodically A clogged filter element results in a higher pres sure drop This can force particles through the filter which would ordinarily be trapped
