However, after having spoken to a number of very experienced automotive machinist, they advise having someone with proper tools and EXPERIENCE with this job...to accomplish it best. If you contemplate what can happen , if this job is done wrong, you can understand what is at stake, if done wrong. I've often wondered if a guy might 'practice' accuracy/technique on worn out disgarded cranks, to acquire the necessary skills to have success. I guess that you only get one chance to do it right on a good crank, eh ? |

Re: full presureing a Model A
Others will no doubt contradict me but I wouldn't drill a model A crank shaft. Don't ask how I know but they are not strong enough to take it without increasing the likelihood of breaking.

Re: full presureing a Model A
A few years ago there was a thread on here about the Model A powered Pietenpol homebuilt plane from the '30's. Someone posted detailed drawings from the day showing how to convert the A engine to aircraft use, including full pressure oiling with a drilled crankshaft. If it held up in the air, should be OK for road use!

Re: full presureing a Model A
I once got a Dayton Globe aero engine from Bill Trone's estate. Bottom part was pure A (crank, rods, cam, timing gears, oil pump). Fascinating thing. Now powering a trials car in England.

Sealing the rear main is a challenge but it can be done Drilling the crank is 1 of those things there are 3 different ways to do it and it must be done by someone with experience I would recommend using the 3 angle method if you find someone with experience Do plenty of research before starting |

Re: full presureing a Model A
Jim Brierley has published a book on the 4 banger and covers how to go about this and whether or not you actually need full pressure for your application. Look him up on here. Its a good read for anyone considering go fast parts on their model A or B.

Re: full presureing a Model A
Clearly pressurizing the A can be done, but in reality it is only needed for a few highly modified engines. The splash oil system is extremely effective for many modified engine builds.
I think it would be wise to explain what you are doing to the engine and ask if it really needs the pressure. |

Re: full presureing a Model A
Why waste time doing something that is commercially available in a much better form? Call SCAT and order what you want already balanced and drilled.

Re: full presureing a Model A
After reading much about how the Model A water pump pushes the water faster than the radiator can flow, I was not surprised to find the below statement in the attached link that Mike provided. Interesting....
