CAUTION:
IAfter removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
IWhen installing chain tensioner, oil seals, or other sliding
parts, lubricate contacting surfaces with new engine oil.
IApply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.

IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled;
Otherwise, you may burn yourself and/or fire may break
out in fuel line.
IBefore disconnecting fuel hose, release fuel pressure
from fuel line.
Refer to ªReleasing Fuel Pressureº in EC section.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be sure to clear surrounding parts.
Use special care for accelerator cable, brake lines and
brake master cylinder.
IIn hoisting the engine, always use engine slingers in a
safe manner.
IWhen removing drive shaft, be careful not to damage
grease seal of transaxle.
Removal
