Removal
1. Remove the MGR chains (paragraph 10). This procedure involves removing the pan (paragraph 14).
2. Unscrew the flange bolts and support nut and remove the intake pipe and filter. Remove the O-ring from the pump.
3. Although not necessary at this stage, remove the screws and remove the oil deflector from the crankcase.
4. Gradually unscrew the pan mounting bolts in the reverse order to that shown in Fig. 15.11. Remove the pump from the cylinder block (see Fig. 15.4, a, b).
Inspection
5. Unscrew the screws and remove the cover from the pump (see Fig. 15.5).
6. Note the position of the marks on the inner and outer rotors and remove them. The mark on the outer rotor faces the cover, and the mark on the inner rotor faces the pump body (see Fig. 15.6, a-c).
7. Unscrew the plug and remove the safety valve, spring and plunger (see Fig. 15.7).
8. If any of the rotors or the pump housing are scored or damaged, the entire pump unit must be replaced. If the components are serviceable, first install the valve parts and tighten the plug. Lubricate the rotors with clean engine oil and insert them into the housing according to the marks (see Fig. 15.8).
9. Install the pump cover and tighten the screws to the required torque (see Fig. 15.9).
10. Before installing the pump, fill it with clean motor oil through the hole in the flange of the intake pipe. At the same time, turn the rotors so that the oil fills the inside of the pump.
Installation
11. Position the pump so that the inner rotor is aligned with the crankshaft flat and mate it with the cylinder block. Insert the bolts and tighten them sequentially (see Fig. 15.11) to the required torque.
12. Install the oil deflector, if removed, onto the crankcase and tighten the bolts.
13. Install the suction pipe and filter together with the new O-ring into the pump. Then insert the flange bolts and tighten them to the specified torque. Install and tighten the support nut.
14. Install the timing chains and align the sprockets (paragraph 10).
