Installing a model B crank into A have some ?'s

John you wouldn't happen to have a part number for the Saturn rod bearings you use?
Also does anyone have a write up on modifing a model A block for pressure oil duty?
 
You can run oil lines from the end of the oil tube exit in the valve chamber to the three gravity feed tubes for the mains. I've not done any pressure oiling, but understand you need a good seal for the rear main.

All of this is pretty well written on the HAMB. Search up the Monthly Banger threads, it is on the first page of references.

And Tom is right, a rear seal is necessary, I have used the Burtz one pc seal though I don't like stretching it over the rear flange.

Enjoy, J
 
answer: I would use inserted rods too, probably new rods as converted B rods need a thrust surface. Pressure oiling is a good idea but also increases the chance of leaks. johnnielson's idea of Saturn bearings is a good one, and likely very available? My book has a chapter on Model A oiling systems (pressure) jimb4e4@gmail.com
 
I have a set of stock B Rods has anyone had any luck with purchasing a set of insert rod bearings from Snyder's with the centering edges and machining the stock rods to fit?
