Does anyone know where to buy a replacement muffler for a cat 212 grader, part # 3B6237?  I've searched all over on line and at tractor stores and availability of tractor mufflers seemed to be quite limited.  

i did find one that fit and looks good off of a allis chamers diesel put in size of the pipe and see what comes up.

try cat classic parts. i found one a listing for the u series d4 which is the same engine. they also had a listing for the pilot engine too.

Pipe off manifold is 2.5" O.D. I'm looking for the short squatty type found on the smaller graders. Most of what I see available are the tall thin type like on most older farm tractors. I used to see mufflers in all shapes and sizes in local stores but now selection is very limited.

It's been years since I went searching but "Walker Muffler" used to have a pretty good website and variety of tractor/industrial mufflers.

the one i found is short looks real good came from jensales in albert lea mn

found the one that i purchased off a 430 case diesel 2.5 inlet overall 26 inches long CA-5 round body

Hello All - Thank you for the responses.
Old Magnet - I looked at the Walker site. They have a large selection of mufflers and exhaust systems but everything I saw seemed to be relevant to newer trucks and vehicles. I didn't see a section for old equipment/farm machinery.
RAZ - I didn't realize it but Jensales has a huge catalog of old mufflers and accessories for older tractors of all types. After looking at 108 pages worth of photos I was still unable to find what I was looking for. Impressive selection though. I thought for sure I would find something close.

I have found the correct muffler on a couple of websites only to find out that the part is "Out of Stock".

I think my next step will be to talk to my Cat dealer's parts department and see what the "indirect replacement" for the correct part number looks like.

Look in the "Commercial" section.
