Oil Pump
REMOVAL AND INSTALLATIONNBLC00051. Remove timing chain. Refer to EM-23, ªRemovalº.
2. Remove oil pump assembly.
IInspect the oil pump after removing it.
3. Reinstall any parts removed in reverse order of removal.

9. Pushing timing chain tensioner sleeve, apply a stopper pin so
it does not return. Then remove the chain tensioner assembly.

10. Remove the 3 water pump fixing bolts. Secure a gap between
water pump gear and timing chain, by turning crankshaft pul-
ley 20É backwards.

12. Tighten M8 bolts by turning half turn alternately until they reach
timing chain rear case.
IIn order to prevent damages to water pump or timing chain rear
case, do not tighten one bolt continuously. Always turn each
bolt half turn each time.
13. Lift up water pump and remove it.
IWhen lifting up water pump, do not allow water pump gear to
hit timing chain.

INSPECTIONNBLC00191. Check for badly rusted or corroded body assembly.
2. Check for rough operation due to excessive end play.

water pump.

3. Before installing, remove all traces of liquid gasket from mat-
ing surface of water pump cover and chain tensioner cover
using a scraper.
Also remove traces of liquid gasket from mating surface of
front cover.
SLC945AA
4. Apply a continuous bead of liquid gasket to mating surface of
chain tensioner cover and water pump cover.
SLC156B
5. Return the crankshaft pulley to its original position by turning
it 20É forward.
SLC961A
6. Install timing chain tensioner, then remove the stopper pin.
IWhen installing the timing chain tensioner, engine oil
should be applied to the oil hole and tensioner.
IAfter starting engine, let idle for three minutes, then rev
engine up to 3,000 rpm under no load to purge air from the
high-pressure chamber of the chain tensioners. The
engine may produce a rattling noise. This indicates that
air still remains in the chamber and is not a matter of
concern.
7. Reinstall any parts removed in reverse order of removal.
