Using a piston ring compressor [SST: EM03470000 (J-8037)]
(A) or suitable tool, install piston with the front mark on the
piston head facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod
big end.
22. Install connecting rod cap.

Match the stamped cylinder number marks (C) on connecting
rod with those on connecting rod cap to install.
23. Tighten connecting rod bolt with the following procedure:
CAUTION:

Make sure that there is no gap in the thrust surface (A) of
the joint between connecting rod (1) and connecting rod
bearing cap (2) and that these parts are in the correct
position. And then, tighten the connecting rod bolts.

If the connecting rod bolts are reused, measure the outer
diameter. Refer to EM-103, "
CONNECTING ROD BOLT
OUTER DIAMETER" .
24. Apply new engine oil to the threads and seats of connecting rod
bolts.
25. Tighten bolts in three steps

After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.

7. Pry off drive shaft from transaxle assembly side as shown.

Make sure that circlip is attached on the edge.
CAUTION:

Do not apply an excessive angle to drive shaft joint when
removing from the transaxle.

Do not excessively extend slide joint.

Do not allow drive shaft to hang down. Support the entire
drive shaft.
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in axial direction. Check for any rough movement or significant loose-
ness.

Check boot for cracks or other damage, and for grease leakage.

If damaged, disassemble drive shaft to verify damage, and
repair or replace as necessary.
INSTALLATION
Installation is in the reverse order of removal. Note the following:

Refer to FAX-8, "COMPONENTS" for tightening torque.
CAUTION:
Do not reuse non-reusable parts.

In order to prevent damage to differential side oil seal, place Tool
onto oil seal before inserting drive shaft as shown. Slide drive
shaft into slide joint and tap with a hammer to install securely.

Install new circlip on drive shaft in the circlip groove on transaxle
side. Refer to FAX-12, "
Disassembly and Assembly (Left Side)" .
CAUTION:
Make sure the new circlip on the drive shaft is securely fas-
tened.

After its insertion, try to pull the flange out of the slide joint by
hand. If it pulls out, the circlip is not properly meshed with the
transaxle side gear.
