Installation: Air compressor
• Set the No. 1 cylinder piston at the top dead center of the com-
pression stroke.
• Align the stamped mark “1” on the air compressor gear with the
projection on the air compressor.
• While keeping this condition, align the stamped mark “1” with the
scribed line on the rear plate and install the air compressor to
the flywheel housing.
Installation: Rear oil seal
• Clean the rear oil seal surface where sealant is to be applied.
• Apply an even and continuous bead of sealant on the rear oil
seal as shown in the illustration.
• Install the rear oil seal onto the flywheel housing within 3 min-
utes following the application of the sealant. Be careful not to
dislodge the sealant.
CAUTION
• Do not start the engine at least for an hour after the rear oil
seal has been installed.
• If the rear oil seal mounting bolts are subsequently loos-
ened, be sure to apply sealant again upon reassembly.
Installation: Ring gear
• Heat the ring gear evenly with a gas burner or the like until it
reaches approximately 200°C.
WARNING
• You may burn yourself if you touch the heated ring gear.
• Fit the ring gear with the side having non-chamfered portions to-
ward the flywheel.
Installation: Flywheel
CAUTION
• Before installing a bolt, check the number of punch marks
on the bolt head. (Bolts with up to two punch marks can be
reused.)
The number of punch marks indicates the number of times
the bolt has been tightened in the past within the plastic re-
gion. If there are three punch marks (tightened three times
in the past), replace the bolt.
