super A engine rebuild

JRSutton · Oct 13, 2011

I've been looking around at rebuild kits and parts, and I've noticed there's not much out there in the way of camshafts or camshaft bearings.

Is it that they don't typically need replacing?

I haven't even started in on the engine yet, so no reason to think there's any kind of problem there, but just wondering what others typically do.

There are no bearings/bushings used on the C113 eninges, the cam runs directly in the block. Most of the time they do not require servicing considering the hours that you will put on it. You may want to get it reground, the lobes but that generally does it.

I agree with Andrew, If a lobe is noticably worn, regrinding, a good used, or a puller regrind might be found. Jim

I see. That would explain why I can't find any info on cam bearings!

Just trying to think everything through to set a realistic budget before starting.

thanks.

In the engines i have rebuilt never raninto a bad cam they run in the area of plenty of lube so they just dont wear. And as others have said there are no bearings. You should pull a sleeve before getting parts wo you know which sleeve you have as your block mite even be able to use the 3 1/4 bore. Remember its 50 pluss yrs old and you wont know what is there till you have the sleeve out. New sleeve,wrist pin and rings start at 52 each complete kit with bearings and all gaskets will run little undrr 400. You need to remove the engine to be able to do the complete overhaul.

Yeah, I was actually budgeting for a full rebuild kit with new valves/springs - that's in the 600 range.

Of course we'll pull the engine first and see what's really needed before purchasing anything.

This is a 4H project, so I don't want to cheap out on the kids, yet, at the same time I want to instill a little frugality. Money we save here will go into better paint/body work.

Can't wait to get going with it. Going to rebuild the carb this weekend with them, and go through the magneto.

I like to do that stuff first while the engine's still running so I can test them and put them on a shelf knowing they work when it's time to re-assemble.

That is a good plan. It is probably more important to teach them to inspect, measure and plan what is needed than it is to teach them how to bolt it back together. Given the properly selected refurbished and new parts, most of them could probably figure out how to bolt it together on their own.
