4. Disassembly, Inspection and Reassembly of Engines
86
[Disassemble]
Since the camshaft gear is shrink-fit, heat it to
180
200 for extraction.
For camshaft removal, raise the engine with its
mounting flange at the bottom. After removing
the thrust metal mounting bolt from the camshaft
gear hole, extract the camshaft carefully so as not
to damage the bearing bushing.
Rotate the camshaft a few turns before extracting
it to prevent the tappet from being caught by the
cam.
After removing the camshaft, set the engine
horizontal and fix it on the base.
Unforeseen injury may arise due to falling of slipping
when raising the engine vertically or returning it to
the horizontal position. Proceed carefully so as not
to lose balance.
Point8: Gear case
[Reassemble]
Do not forget to install the oil pan mounting bolts
on the bottom side when installing the gear case.
Apply sealant (code No.977770-01212) and install
the gear case by matching the two dowel pints.
