62. Oil Pump Assembly Cleaning and Inspection
1. Inspect bearing on flange for excessive wear or damage.
2. Inspect machined surfaces for scratches or nicks that may cause a fluid leak.
IMPORTANT: While flushing, rotate oil pump rotor with oil pump drive shaft. Rotating oil pump rotor flushes clean fluid through oil pump.
3. Thoroughly flush oil pump with clean transaxle fluid through pump inlet and outlet passages.
4. Drain excess fluid from oil pump assembly.
