    John Deere 644 won t stay running

    Ok guys I was finally able to work on the loader again. First I put on a fuel pressure gauge and confirmed that fuel pressure stays up when the engine dies. Next I took off the pump timing cover and turned engine over catching the fuel. Noted some black and brown stuff in the fuel that came out...

    John Deere 644 won t stay running

    Hi, my father recently purchased what we think is a 1969 John deere 644. The loader starts easy and sounds healthy but won t stay running for more than a minute or so.

    Ford 4400 sos noise

    Bern, thanks for that. Great info. This definitely could be the problem. I noticed the oil was full of tiny bubbles but wasn t sure what could be done about it. The noise is bad enough that I don t like using the tractor around other people so it would be worth it to me to fix. I have a pretty...

    Ford 4400 sos noise
