Engine Willys L-134 Go Devil |
Function Pulley lock on crankshaft |
Features
- Correct dimensions for L-134 engine crankshaft groove
- Prevents pulley rotation on the crankshaft
- Essential component during pulley removal/installation
- Suitable for both single and double pulley versions
- Replacement part for wear or loss
★ Critical component for correct crankshaft pulley mounting. During installation use a small amount of grease to hold the key in position — ensure the crankshaft position is between 10 and 2 o'clock so that gravity holds the key in place.
Installation notes
Apply a small amount of grease to the key to temporarily hold it in the groove during pulley installation. Ensure the crankshaft is in the 10 to 2 o'clock position during removal/installation — at 6 o'clock the key will fall out of the groove due to gravity. Mark the position of the groove on the crankshaft tip for reinstallation.
Compatibility
Fits all Willys L-134 engines with crankshaft pulley. Note: this is a different key from the Woodruff key for the crankshaft sprocket (on chain-driven camshafts on early MB/GPW engines).
Historical context
The Woodruff key is a half-moon shaped locking key that has been used in engine construction since the early 20th century. The name derives from inventor John H. Woodruff who patented this design in 1888.
