16. Install knock sensor.

Install it with its connector facing the rear of engine.

Install the sub-harness with its shorter branch line to the right
bank.
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 back surface of knock sensor.

Make sure that knock sensor does not interfere with other parts.
17. Note the following, and 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, reinforcement plate and pilot converter (if
not installed in step 4) as shown in the figure.

Face chamfered or rounded edge side to crankshaft.

Holding ring gear with ring gear stopper [SST: J-45476].

Tighten mounting bolts crosswise over several times.

When install pilot converter, using drift [outer diameter:
approx. 35 mm (1.38 in)]. Press-fit as far as it will go.
CAUTION:
Make sure that guide pin is installed at the rear end of
crankshaft.

CautionNDS000C0
Observe the following precautions when disassembling and servicing drive shaft.

Joint sub-assembly does not disassemble because it is non-overhaul parts.

Perform work in a location which is as dust-free as possible.

Before disassembling and servicing, clean the outside of parts.

Prevention of the entry of foreign objects must be taken into account during disassembly of the service
location.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
