★ Small but essential cover plate that protects the engine against contamination via the flywheel inspection opening.
Application
For vehicles with L-134 Go Devil engine where the timing marks are located on the flywheel. Early production vehicles used this opening to adjust the ignition timing via the marks on the flywheel, rather than via marks at the front of the engine.
Installation notes
Fit the cover plate with the correct gasket or sealant to prevent oil, dust or moisture from entering the clutch housing. The opening is located in the rear engine plate (bell housing), above the starter motor.
Compatibility
Fits vehicles with L-134 engine that are equipped with a timing inspection opening in the rear engine plate. Not all engines have this opening — later production vehicles received timing marks on the crankshaft pulley and timing cover at the front.
Historical context
Early L-134 engines had the ignition timing marks engraved on the flywheel. Through a small hinged cover plate in the rear engine plate, the mechanic could check and adjust the timing. From the early 1950s, Willys relocated the timing marks to the front of the engine for easier maintenance.
