Does anyone know if a D7 7M piston is the same as a RD6, 6B3912 is the casting # on my RD6, i think it changed up to 3B9737, thanks
Come on somebody must know. From the RD series D6,D7,D8, to D7E and the D8K the piston was 5 3/4. But way above my knowledge level to know just how interchangeable they all are.
I don't know there answer, I couldn't find a match for the part number in the RD8 parts manual. You might get more responses if this was posted in the discussion pages.
If I can remember when I go to the shop tonight I will look and see if I can find some info.
Answer is , yes, the numbers cross, in fact 6B3912 and 3B9737 show as used in D17,000 D13,000, etc, and cross to 7M and others, including the RD6.
Just a little insight, but my D17000 is early and had the six ring set up. Just food for thought.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
