DISASSEMBLY
1. Remove engine, transaxle and transfer assembly from the vehicle, then separate engine and transaxle
and transfer assembly. Refer to EM-222, "
ENGINE ASSEMBLY" .
2. Remove clutch cover and disk. Refer to CL-16, "
CLUTCH DISC, CLUTCH COVER AND FLYWHEEL" .
3. Install engine to engine stand as follows:
a. Remove flywheel.
b. Secure ring gear with the ring gear stopper (special service
tool), then loosen mounting bolts with TORX socket (size: T55,
Commercial Service Tools) and remove them. As an alternative
method hold crankshaft pulley with the pulley holder (special
service tool: KV10109300) to remove flywheel.
CAUTION:

Do not disassemble flywheel.

Do not place flywheel with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.
c. Install the engine sub-attachment (special service tool) to the
rear side of cylinder block.

Align knock pins on cylinder block with pin holes on attach-
ment to install.
NOTE:
Installation bolts are part of engine sub-attachment.
d. Install the engine stand shaft (special service tool).
NOTE:
Use commercially available M12 (0.47 in) mounting bolts and
nuts (4 sets) with strength grade of 9T (minimum).

INSPECTION
Installation and inspection of torque converter

After inserting a torque converter to a transaxle, be sure to
check distance “A” to ensure it is within the reference value limit.
InstallationECS004ND
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts to the specified torque. Refer to AT- 4 1 6 , "
Com-
ponents" .
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
the front of the engine.

When tightening the tightening bolts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts.

After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transaxle rotates freely without binding.

After completing installation, check for fluid leakage, fluid level, and the positions of A/T. Refer to AT- 1 6 ,
"Checking A/T Fluid" , AT- 4 0 9 , "CONTROL CABLE ADJUSTMENT" .

ENGINE MAINTENANCE (YD22DDTI) PFP:00100
Checking Drive BeltsELS000CC

Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing the crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentELS000K5
Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid varia-
tion in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant etc.

Do not twist or bend the belts with strong force.
