REMOVAL & INSTALLATION
See Figures 1 and 2
- Rotate the crankshaft until the No. 1 cylinder is at the TDC on the compression stroke.
- Drain the crankcase oil. Remove the splash shield, if equipped.
- Remove the high-tension wires and the distributor.
- Remove the oil pump bolts and pull the pump out.
To install, use a new oil pump gasket and perform the following:
- Fill the oil pump housing with clean engine oil.
- Align the drive pump hole and spindle mark by turning the spindle. Then, turn the spindle one gear tooth to the right.
- Install the pump and tighten the mounting bolts to 8-11 ft. lbs. (10-14 Nm).
- The projection on top of the spindle should now be at the 11 o'clock position, with the smaller half of the spindle facing forward.
- Reinstall the splash shield. Refill the crankcase with new oil.
- Reinstall the distributor and the hold-down bolt, carefully rotating the rotor back-and-forth until the bottom of the distributor shaft engages the projection on top of the oil pump spindle.
See Figures 1 and 2
- Drain the crankcase oil.
- Turn the crankshaft so that the No. 1 piston is at TDC of the compression stroke.
- Remove the distributor cap and mark the position of the distributor rotor in relation to the distributor base with a piece of chalk.
- If equipped, remove the front stabilizer bar. Remove the splash shield.
- Remove the oil pump body with the drive spindle assembly.
- To install, fill the pump housing with engine oil, align the punch mark on the spindle with the hole in the oil pump. The No. 1 piston should be at TDC of the compression stroke.
- Install a new gasket (placed over the drive spindle), the oil pump and the drive spindle assembly, making sure the tip of the drive spindle fits into the distributor shaft notch securely. The distributor rotor should align with the chalk mark made earlier.
Great care must be taken not to disturb the distributor rotor while installing the oil pump or the ignition timing may be wrong.
- To complete the installation procedures, reverse the removal procedures.
See Figure 3
- Refer to the Oil Pan and Timing Belt removal and installation procedures in this section, then remove the oil pan and the timing belt.
- Remove the crankshaft timing sprocket (it may be necessary to use a puller) and the timing belt plate.
- Remove the oil pump strainer and pick-up tube from the oil pump.
- Remove the oil pump retaining bolts and the oil pump.
- To install, use new gaskets (use silicone sealant), an new oil seal and reverse the removal procedures. Tighten the bolts to 4-5 ft. lbs. (5-6 Nm) for 6mm bolts or to 9-12 ft. lbs. (12-16 Nm) for 8mm bolts. Refill the crankcase.
Before installing the oil pump, be sure to pack the pump's cavity with petroleum jelly, then make sure the O-ring is properly fitted.
