I have the engine installed now after getting overhauled and the dowel pins are missing? it appears they should be stepped 5/16 to 3/8 " does anyone know if there is supposed to be pins installed here normally? I can machine now ones if they are required, I cannot find them in the MAC's book. Cheers

A little more info would be helpful. Of the few places on a flathead that has dowels that I can think of, I would want them back in each place. They were put there for a reason. You might try NAPA. I don't think any of them are stepped to a different diameter. If so someone here will certainly let you know.

My bad, I see you are talking about the ones on the bellhousing. I would definitely want those in there as trans position and lineup are critical.

I was also wondering which dowel pins we were talking about here. I believe I have seen those bell housing dowel pins available somewhere. It may have been in MAC's Antique Auto Parts catalog where I saw them advertised. When I trashed some old flathead blocks I recall removing some of those dowel pins in case I ever needed them but where they are now is anybody's guess. I don't believe these pins were stepped and they are made from a very hard steel similar to a roller bearing. Sorry, not that much help. JM

The dowel pins used to locate the transmission to the clutch housing are part number 18-6397. The same pins were used from 32-48. The length is 11/16". I don't have the diameter, but any rod stock that fits the holes can be used. I haven't seen them in parts catalogs. If you make them, be sure to champfer the ends to assist in installing the transmission.

Thank you lads, Again exactly waht i needed, I have made a few for large trucks we work on I'm more familiar with large diesels, I might have some the correct size,I use Drill rod turned and ground. It seemed funny I got a few good drawings on the internet but no dowels were shown, I didn't see any on the 2 army trucks I have, must be just covered up. Cheers

Give a call to Antique Auto Supply in Arlington, TX. It's been some time but I bought these dowels from him. 817-275-2381 Ken
