Hello,

I am in the early stages of rebuilding my 1917 Model T engine and I'm looking for some advice for preparing my block for machining. I've disassembled it almost entirely and cleaned/degreased it well.

My question is: do I need to remove the crank and cam shafts prior to sending it away for decking, cylinder boring, and valve seats?

I think it is likely I will need to remove the crank (so metal chips don't get into the babbitt area..) but I am unsure about the camshaft.

Any advice is greatly appreciated!

Cheers,
A

If I was getting machine work done I believe I would strip it all the way down. That’s what I did with the ones I had bored. If your removing the crankshaft the cam removal also is not that much more to do.

Is there anything I need to be careful of when removing both shafts? I would definitely mark the timing gear position for reinstallation, anything else?

The timing gear and crank gear are already factory marked but you can do that if you’d like.

Which Vancouver BC or WA?

Make sure your rods & main caps are clearly marked for reassembly. Never notch rods. If someone before you has, grind them out. Be sure the builder doesnt hot tank it. Ruins babbit. Make it clear you want the babbit protected if you are not rebabbitting. Clean water jackets before sending out. When/if you have the crank ground, have both sides of the flange squared up. Rear side only if using old babbit.

If the machine shop Hot tanks the block it ruins the babbitt.

Thanks for the advice everyone!

Looking forward to getting a well-condition block from the machine shop.

I am in Vancouver, BC by the way.

Cheers
