Air Injection Pump: Overhaul: Inspection
Clean rear and vane hub bearings in suitable solvent. Clean carbon dust from pump housing and rotor assembly with an air hose.
NOTE:
Do not use cleaning solvent on pump housing and rotor assembly.
Inspect all parts for damage or wear, replace parts as necessary. If side carbon seal is scored (three vane type), replace it. Rear and vane hub bearings must be lubricated with a high melting point grease (Esso Andok 260).
