18. Install knock sensor.
Install knock sensor so that connector faces front of theengine.
After installing knock sensor, connect harness connector, and lay it out to rear of the engine.
CAUTION:
Do not tighten mounting bolts while holding connector.
If any impact by dropping is applied to knock sensor, replace it with new one.
NOTE:
Make sure that there is no foreign material on the cylinder block mating surface and the bac k surface of knock sensor.
Make sure that knock sensor does not interfere with other parts.
19. Note the following, assemble in the reverse order of disassembly after this step.
Drive plate When installing drive plate to crankshaft, be sure to correctly align crankshaft side guide pin and drive plate side guide pin hole.
- If these are not aligned correctly, engine runs roughly and “MIL” turns on.
Install drive plate and reinforcement plate as shown in the fig- ure.
Holding ring gear with the ring gear stopper [SST: KV10117700 (J44716)].
Tighten the mounting bolts crosswise over several times.
CAUTION:
Make sure that dowel pin is installed at the rear end of
crankshaft.
How to Select Piston and BearingINFOID:0000000001325748
DESCRIPTION
*: For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only “0” grade is a vailable.) The
information at the shipment from the plant is described as a reference.
The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
For reused or repaired parts, measure the dimens ion accurately. Determine the grade by comparing the
measurement with the values of each selection table.
For details of the measurement method of each part , the reuse standards and the selection method of the
selective fitting parts, refer to the text.
