Installation notes
Note: The flywheel bolts are fitted from the engine side through the crankshaft flange, with nuts and lock washers on the clutch side. For installation, the oil sump and rear crankshaft bearing cover must be removed. Ensure that one of the flat sides of the hexagonal bolt head rests against the lip of the crankshaft flange, not a point. Tighten to manufacturer's specification.
Compatibility
Note: This concerns the hardware set (bolts, nuts, lock washers) for flywheel mounting. Early engines had 4 straight 3/8" bolts + 2 tapered dowel bolts. When replacing flywheels, the tapered dowels were sometimes replaced with straight bolts. Check your specific configuration before ordering.
Historical context
The F marking on these bolts refers to Ford Motor Company, which produced GPW jeeps alongside Willys-Overland during WWII. Ford and Willys used different suppliers, resulting in different bolt markings such as F (Ford), EC and AA (Willys).
