INSPECTION OF OIL PUMP 1. CHECK BODY CLEARANCE OF DRIVEN GEAR Push the driven gear to one side of the body. Using a feeler gauge, measure the clearance. Standard body clearance: 0.07 — 0.15 mm (0.0028 — 0.0059 in.) Maximum body clearance: 0.3 mm (0.012 in.) If the body clearance is greater than the maximum, replace the drive gear, driven gear or pump body. 2. CHECK TIP CLEARANCE OF BOTH GEARS Measure between the gear teeth and the crescent-shaped part of the pump body. Standard tip clearance: 0.11 — 0.14 mm (0.0043 — 0.0055 in.) Maximum tip clearance: 0.3 mm (0.012 in.) If the tip clearance is greater than the maximum, replace the drive gear, driven gear or pump body. 3. CHECK SIDE CLEARANCE OF BOTH GEARS Using a steel straightedge and a feeler gauge, measure the side clearance of both gears. Standard side clearance: 0.02 — 0.05 mm (0.0008 — 0.0020 in.) Maximum side clearance: 0.1 mm (0.004 in.) If the side clearance is greater than the maximum, replace the drive gear, driven gear or pump body. 4. INSPECT FRONT OIL SEAL Check for wear, damage or cracks. 5. IF NECESSARY, REPLACE FRONT OIL SEAL (a) Pry off the oil seal with a screwdriver. (b) Using SST and a hammer, install a new oil seal. The seal end should be flush with the outer edge of the pump body. SST 09350-20013 (09388-20010)
