Greetings. My brother-in-law, who is a decent fellow, has a 1981 JD 350C track loader that is missing at higher rpm. He says that there is very little power when digging, or working the machine, though the miss is not as evident at an idle. He has cracked the fuel lines and said that the number two cylinder seems to be the one with the miss. (ie: no change in the sound when he tried cracking the line - and the other two cylinders immediately produced heavy additional missing) He changed the injector on this cylinder but it had no apparent effect on the miss. I recall reading something about bent pushrods in one of these threads, but can't recall where it was located. Could something like that be his problem, or maybe somewhere else? The loader is in great shape otherwise, and does not have many hours at all. Thanks for any help.
This one mentioned something bout it "Injection Pump was rebuilt... Fuel got into oil first start-up." It's in the loader/backhoe section i think
There is a site called "JD Crawlers" ....you might get the help you need there. Jim
350 Digger Thanks for the input and directions to information. I will pass these along to him and perhaps someone with a similar machine and problem will post their solution or thoughts.
