Oil Pump: Service and Repair

Removal

1. Drain the engine oil.
2. Remove the oil pan.
Insert the blade of SST(09215-3C000) between the ladder frame and the oil pan. Cut off applied sealer and remove the lower oil pan.





NOTE:
- Insert the SST between the oil pan and the ladder frame by tapping it with a plastic hammer in the direction of arrow (1).
- After tapping the SST with a plastic hammer along the direction of arrow (2) around more than 2/3 edge of the oil pan, remove it from the ladder frame.
- Do not turn over the SST abruptly without tapping. It be result in damage of the SST.
- Be careful not to damage the contact surfaces of Upper oil pan and lower oil pan.

3. Remove the timing chain.

4. Remove the oil pump (B), oil pump chain (A) and sprocket.






Installation

1. The key of crankshaft should be aligned with the mating face of main bearing cap. As a result of this, the piston of No.1 cylinder is placed at the top dead center on compression stroke.
2. Assemble the crankshaft sprocket on the crankshaft as the front mark on the crankshaft sprocket to be outward.
3. Tighten the oil pump tensioner bolt 'A' after placing the tensioner spring on the dowel pin located in ladder frame and then insert stopper pin to fix the oil pump chain tensioner 'B'.

Tightening torque :
9.8 - 11.8N.m (1.0 - 1.2kgf.m, 7.2 - 8.7lb-ft)




4. Assemble the oil pump chain on the crankshaft sprocket.
5. Assemble the oil pump assembly (B) as placing oil pump sprocket in to oil pump chain (A).

Tightening torque :
7.8 + 16.6 + 25.5 N.m (0.9 + 1.7 + 2.6kgf.m, 5.8+ 12.3 + 18.8 lb-ft)




Bolting order
A. Assemble the bolts with seting torque 25.5 N.m (2.6kgf.m,18.8 lb-ft)
B. Loosen the bolts as reverse bolting order.
C. Assemble the bolts (4EA) with seting torque 0.9 N.m (7.8kgf.m, 5.8 lb-ft)
D. Assemble the bolts (4EA) with seting torque 1.7 N.m (16.6kgf.m, 12.3 lb-ft)
E. Assemble the bolts with seting torque 25.5 N.m (2.6kgf.m,18.8 lb-ft) as bolting order.
6. Remove the tensioner pin after installing the oil pump chain guide (D).

Tightening torque :
9.8 - 11.8N.m (1.0 - 1.2kgf.m, 7.2 - 8.7lb-ft)

7. Install the timing chain.
