★ Original part from military stock, never used. These valve tappets were originally produced for WWII production and are still in perfect condition today.
Application
Suitable for all vehicles equipped with the Willys L-134 (Go Devil) flathead side-valve engine. This includes early military jeeps and early post-war civilian models. Please note: 8 valve tappets are required per vehicle (4 inlet, 4 exhaust). Price is per piece.
Installation notes
The valve tappet is positioned between the camshaft and the valve stem. During installation, the valve clearance must be correctly adjusted using the adjusting screw. Recommended valve clearance:.020" (0.508 mm) for timing check, to be reset to correct operating value after adjustment. For adjustment, special valve tappet spanners (#41-W-3575) are recommended.
Compatibility
This part fits engines with L-134 flathead configuration. Please note: this is NOT suitable for the later F-134 Hurricane overhead valve engine. The L-134 engine was used in WWII MB/GPW vehicles and early post-war models. Early vehicles had chain drive for the camshaft, later models gear drive — both use the same valve tappet.
Historical context
The L-134 'Go Devil' engine was the most powerful four-cylinder engine in its class during WWII and became the standard for military jeeps. The valve tappet was a simple yet critical component in the robust L-head (flathead) configuration known for its reliability under extreme conditions.
