Hi

I just had the head on my RC rebuilt. Got it back together and everything seems to be running fine. I re-used the old valve cover gasket so I could run the engine a bit before re-troqueing the head bolts and checking the tappet clearance. After I was sure all was well, it was time to put on the new valve cover gasket. It didn't fit, it was 1/4 th inch to long.

I always thought that an RC was a WC frame with a B engine. My machinest couldn't find a gasket set for an RC so he got a set for a B. The head gasket was an exact match. The RC is a low serial number. Are there some differences between a B and an RC engine or do I just have a bad gasket set.

Any old timers out there that know the answere to this one?

Thanks in advance D.D.Post

The B actually had 3 different engines - the 113 cubic inch waukesha (first 96 tractors or so), the 116 cubic inch BE engine, and the 125 cubic inch CE engine. Did you get the gasket set for the BE engine or the CE engine? No idea if the valve covers are the same or different for these two.

I *think* the RC used the 125 cubic inch CE engine (look for the engine serial number on the left side of the tractor on the flange that connects to the transmission) but I'm not sure of that - and I don't have my book handy. You just might have a gasket set for the BE engine ... or maybe not.

Thanks for the reply.

I did some checking last evening. The serial number on the engine block is R225G. According to my reprint RC parts book the R is for RC, the #, is the serial, and the G indicates gas fule vs K for kero. I guess the RC has its own set of numbers so it don't help to determine what sort of B it is equivilant to. The reprint parts book lists the engine as 125 cid.

My IT Allis book lists the RC as 125, and lists the BE/B as 116 and 125 cid. I was arware of the smaller B engine, but I had never heard of the even smaller B engien by Wakasha before.

The gasket set is Victor Reinz ( Dana corp ) and says for Allis Chalmers B. I suspect the problem is with the gasket set. Also the gasket for the water outlet at the front of the head was incorrect. The one form the set was rectangular except one side of the rectangle was curved and bowed outward by about a half an inch. The water outlet on my RC head is a rectangle, so I had to make this gasket.

I guess this don't really matter, but it would be nice to know. I will probably take this engine down and rebuild the bottem end in a couple of years. It would be nice to be able to get the correct parts when I do.

When I took the head off, I mesured .028 space from the top end of the piston to the cylinder wall below the ridge. The ridge at the top of the cyinders is about .006. Last time I had this engine apart was in 1960 when we put new sleves and pistons in it. About the same we also got a bigger and more modern tractor on the farm so this engine didn't see that much use, I was surpried to see that much wear. I suppose 40 years takes its toll as well. The engine however seems to run great now so I might concentrate of fixing other things like the electrical system.

Enough, and thanks again for the info.

I don't think there was any external difference between any of the AC made B, C, CA engines. There were differences inside, but not in the external dimentions. Suspect your gasket is long or has expanded in storage.

Today's Featured Article - Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc ... [Read Article]
