The third type of inspection is the visual

method.

1/4 inch)

in flywheel

clearance

holes.

WARNING

Fuel cut-off control at driver’s position

must be pulled all the way out to

prevent engine from starting. Personnel

could be injured or killed if engine

starts during this PMCS check.

b.

Two people are required to perform the

visual method. One will be inside the

vehicle manually jerking the engine.

Meanwhile the second will be under the

vehicle observing the relative motion

between the flywheel’s clearance holes and

the spline drive ring’s studs and nuts.

Remove the four bolts, washers, and gasket

from the access cover under the vehicle

directly under the powerpack.

Push the hydraulic hoses to the side and

look into the access opening. You will

see the rear bottom side of the engine’s

flywheel cover as well as a 2’’ by 3’’
