Lapel, In | No longer around the dealer shop, but it sounds like Deere might have used some green blocks. Same situation occured with Deere rushing to get the 5010 on the market. I had to counter bore the 5010s we sold and shim up the sleeves to their proper height protrusion. Chrysler had the same problem with some of the old Plymouth Furys back in the late 50s, but they had no sleeves,only soft blocks.
. Engine block casting are ordinarily thrown outside in a pile for about 6 months where they are aged before any machining is done. It gives the iron molecules time to settle down(harden) and stabilize. That is what Deere engineers told me at the Waterloo Tractor Works at a service school back in the 60s or 70s. | |
