14. INSTALL REAR OIL SEAL RETAINER
(a) Remove any old packing (FIPG) material and be careful
not to drop any oil on the contacting surfaces of the oil
seal retainer and cylinder block.

Using a razor blade and gasket scraper, remove all
the old packing (FIPG) materials from the gasket
surfaces and sealing grooves.

Thoroughly clean all components to remove all the
loose material.

Using a non±residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the oil seal retainer as shown in the
illustration.
Seal packing: Part No. 08826±00080 or equivalent

Install a nozzle that has been cut to a 3 ± 4 mm (0.12
± 0.16 in.) opening.

Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.

Immediately remove nozzle from the tube and rein-
stall cap.
(c) Install a new O±ring to the cylinder block.
(d) Install the oil seal retainer with the 7 bolts.
Torque: 8.0 N´m (80 kgf´cm, 71 in.´lbf)
15. INSTALL ENGINE COOLANT DRAIN UNIONS
(a) Apply seal packing to 2 or 3 threads.
Seal packing: Part No. 08826±00100 or equivalent
