I'm ready to take my block, crankshaft & head from my SC to a reputible machine shop to prepare it for rebuild. Any advice or suggestions for the normal routine would be appreciated - never done this before.

I've ordered a comprehensive engine kit from this site - less bearings (best to let shop match them up?). I'm sure they'll want the valves & guides, etc.

Any other do's or dont's??

Thanks

Doug

Thanks a lot guys.

ScottyHOMEy - I don't think the seats are too bad. I've owned & used this tractor for 20+ years. Old valves are still in. Looks like normal wear, But I'll prepare.

$179.00 for a set of head bolts? Seems like a lot! Only a couple have slight/med. rust. Can I still use them if I don't mangle them taking 'em out?

Any idea the condition of your valve seats?

The head on my BN had been so full of water for so long that the seats were beyond salvation, and he had to machine it to take inserts. (The head on the BN did not have inserts, the seats were machined right into the head, and I think that's the case, too, with your SC head.) Just brace yourself for that, if it comes up.

I agree, too, that it's a good idea to let the shop that turns the crank supply the bearings. The shop I took mine to said they like it better that way, as well.

Thanks Glennster, I'll gather all that stuff up.

I think the cam does go right through the block w/o bearings.

Head bolts are still in. I suppose they should come out before I take it.

Doesn't look like it will have to be milled down, but again I'm not a machine shop guy. Should they have the sleeves also, in case want to mill everything down together?

i pulled the studs on mine and are replacing them with new ones. tme machine shop got them from ARP. automotive racing products. they were 179.00 for the set with nuts and washers, i-h wanted 280 for the set. you can have him fit the sleeves too. mark the piston and sleeve sets with a magic marker so you can keep them together.

Why did your studs require replacement?

i just got my super m motor back from the machine shop. they cut the crankshaft, resized the connecting rods, hot tanked and new cam bearings in the block, did the head, new valves, guides, springs, seats ect. i got the kits from this site. i am not sure but i dont think the super c had cam bearings, i think the cam ran right in the block. have him check the cam too, check your lifters also. you may want to have the machine shop go over the oil pump too.
