Engine Oil Pump - Installation

INSTALLATION





1. Lubricate the pump with clean engine oil. Filling the pump with clean engine oil during installation will help to prime the pump at engine start up.
2. Install the pump. Verify the idler gear pin is installed in the locating bore in the cylinder block. Tighten the oil pump in 3 steps, in the following sequence.
- Step 1: Push the pump firmly against the cylinder block and install the four (4) bolts finger tight.
- Step 2: Tighten the bolts to 8 Nm (72 in. lbs).
- Step 3: Tighten the bolts to 24 Nm ( 18 ft. lbs)





3. The back plate on the pump seats against the bottom of the bore in the cylinder block. When the pump is correctly installed, the flange on the pump will not touch the cylinder block.
4. Measure the idler gear to pump drive gear backlash and the idler gear to crankshaft gear backlash. The backlash should be 0.15- 0.25 mm (0.006-0.010 inch). If the backlash is out of limits, replace the oil pump.
5. If the adjoining gear moves when you measure the backlash, the reading will be incorrect.
