52.0.5 Oil pan and oil filler
Vehicles produced before a certain date in 1942 included an early style oil pan which used a cast drain boss, attached to the pan with three rivets and sealed with solder*. The oil pan is fastened to the engine block with recessed hex head integral-lockwasher bolts. The crankshaft pulley shield is fastened to the timing chain cover with four recessed hex head lockwasher bolts that also hold the front of the oil pan. Spacer rings are used between the shield and the pan to prevent interference. The threaded ends of the bolts should not extend too far past the timing cover flange. The pulley shield is properly marked with a script “f”.
Three styles of oil filler tube and dipstick were used during GPW production: A) The Very Early style (PN GPW-6763A) with narrow cap was used from start of production thru March ‘42. B) The Early style (GPW-6763B) with friction-fit funnel top was used from April ‘42 thru Dec ‘42. C) The late style (GPW-6763C) with crankcase vent and bayonet cap was introduced Feb. 8th 1943 and was used thru the end of production. **
The oil pump is marked GPW 6604 with a script “f”
* Have been unable to find any reference to change in oil pan. Date should be determined based on documentation or observation. ** Changeover date courtesy Jim Gilmore based on Ford archival research.
