Buda engines were bought up by Allis Chalmers, may be some parts there, but Allis too is now history. I found that Steiner has a lot of parts, but few engine related, mainly sheet metal etc. Not a lot of diesel 30's and not many left, more 40 & 50 diesels, esp the Perkins 270's. A&I may have parts as well . I would also try Canadian wrecking yards, as Cockshutt was a Canadian tractor, big one is Fawcett's in St. Mary's and there are a few big wreckers in the prairies. My old girl is a gasser, lots of them around.

Most of the inner parts such as pistons,rings and bearing are the same as on the 40's, and are can be purchased from Phil Heisey at 215-256-8651.

We've overhauled and painted the old girl since these pics were taken. I had no idea those fenders were that rare. Do you have another set of those fenders? My body guy pieced them together best he could, but they're still a little ugly.

I'm rebuilding my E4 gas.  I found cylinder kits from Howard Enterprises (Indiana) through Rick's Ag Parts neat Wooster, Ohio.  I can't remember if they also made diesel kits.  The only A-C tractor that used Budas was the very late WD-45 with the 6BD230.  I think only the last two years.

That Buda engine website hasn't worked in years.  I did get in touch with James Cousins last spring but he didn't have much.
