just an update on the 310 rods / machine shop problem , after 1 year & lots of complaining they finally got them done , ended up buying 2 used rod ( they claimed 2 of mine where junk but engine ran fine cost $100 core ) 3 rods have oversize bushing 3 dont , new bolts they claimed only could be obtained from AGCO for $17 each , tryed to charge me $1300 total , of course i complained so they took $300 off the bill & gave me a free T-shirt ( grease rag now) , never gave me my 2 so called junk rods or old bolts back , they gave me every exscuse & reason for the bill they could , i just payed the ransome & left , ive never been so glad to be ripped off in my life just to end all dealings with this shop , sounds nuts but true im glad its over , will never go back . its sad that a shop made me feel that way i think.
