Howdy,

I have been looking for a block off and on for my JD R since mine needs major work to stop a water leak under the cylinders. My question is how hard is it to pair up a block from an 830 to a JD R? If memory serves me correct, they are pretty much the same block. I don't know about the linkage to the injection pump and how that will pair up but everything looks similar. Also, this block is bored out .045 so I will need new pistons. Any sources for pistons that size? Thanks in advance and God bless.

80/820/830/840 blocks are pretty much the same. Making more than a R's rated HP is a short trip to a broken two bearing crank.

Pistons should not be a problem if they are the same nominal size, I would think. Bore the replacement block to fit or turn the pistons to fit. Probably both would be ideal, but remember you need a size for which rings are available, or just make your own if you are equipped with a lathe (well, compression rings anyway - not so sure about oil control.
