Hi Glenn The changes are reasonably well depicted on Dwg 8 of the 1933 plans drawnby Orrin Hoopman. Some of the missing detail is I suppose due to assumedknowledge of the A. In stock configuration the A is oil by gravity and splash. The large oiltube that runs at an angle from the valve chamber drains oil into the timingend or front of the splash pan. This oil runs back filling the dippertroughs of the pan splash pan. Oil runs by gravity from the valve chamber tothrough the drillings in the block to the main bearings.The conversion has the cast iron side cover replaced with a steel sheet.When you remove the cover you will see a tube cast into the block thatslopes up from the oil pump towards the cam gear end of the valve chamber.This is the oil pump outlet. The copper line inserted into the oil outletcarries oil from here to the front (formerly rear main) and is T'd into thecenter main.The 1/8th pipe plug just above the pan flange on the oil pump casting bumpis a pressure port. ( If you want to scare yourself put an oil pressuregauge here
. This line, from the port, fills oil into the prop end of thesplash pan for the connecting rod dippers. The other line from the bottom ofthe rear end of the valve chamber drains the oil from the chamber to thefront end of the splash pan. You will have to drill and tap this hole. 1/4"seems small but I figure that Bernie was counting on less oil in the chamberby piping it from the pump outlet to the front of the splash pan. Notice inthe drawings that the splash pan has dams and baffles welded into it. Someof the early A's had a tube pressed into the rear main to carry oil awayfrom the crank main slinger. Cut this tube off and extend the splash pan tocatch the oil.If I was doing it I would consider having an aluminum pan made up that steelpan is heavy.Hope this helpsJohn Mc-----Original Message-----

I am trying to locate thisinformation for a friend that is strongly considering builting a Piet, butonly if he can get some answers before he starts. I will give him yourinformation, which I know he will appreciate very much!He is very knowledgable on the Model A engine (he has rebuilt many) andshould have no problem with your description.Thanks very much!Glenn________________________________________________________________________________
