CYLINDER
See General Warning, Section 1, Page 1-1.
Test cylinder compression using a standard compression tester. Low compression would normally indicate a
problem in the cylinder assembly such as defective rings, gaskets, etc.
FE400 model engines are equipped with an automatic compression release valve (ACR). This valve releases
compression pressure at normal cranking RPM, resulting in lower compression. At a normal cranking speed
of 550 - 600 RPM, the compression should be typically 71 psi. This value could vary slightly depending on
wear of components affecting compression.
BREATHER VALVE (REED VALVE)
The function of the breather is to create a vacuum in the crankcase which prevents oil from being forced out
of the engine through the piston rings, oil seals or gaskets. The breather has a reed valve which limits the
direction of air flow caused by the piston moving up and down. Air can flow out of the crankcase, but the one-
way reed valve blocks return flow. It thus maintains a vacuum in the crankcase.
Oil laden air in the crankcase passes through the reed valve and expands into the rocker chamber. In the
rocker chamber most oil separates from the air and drains back to the crankcase. The air passes through a
tube and vents to the intake manifold.
VALVE CLEARANCE CHECK AND ADJUSTMENT
No clearance check or adjustments are required. The FE400 engine is equipped with hydraulic lifters that
automatically eliminate all clearance in the valve train components.
CRANKCASE
See General Warning, Section 1, Page 1-1.
ENGINE REMOVAL
To perform repairs on crankcase components, remove engine from the vehicle. See following CAUTION.
CAUT ION
• Before removal and disassembly, clean the engine.
1. Remove the powertrain. See Unitized Transaxle Removal, Section 16, Page 16-6. See following
NOTE.
NOTE: The crankshaft has left-hand threads at the clutch mounting hole.
2. Remove starter/generator. See Starter/Generator (Model G425419), Section 12, Page 12-1.
3. Remove drive clutch. See Drive Clutch, Section 17, Page 17-4.
