    2008 cat 420e backhoe stuck in first gear

    Well Shoot, I was thinking that maybe I could access those parts through a cover or something, but the parts book doesn't show anything like that. It does however show access to a spring detent ball on one of the shift rods. I am hoping that I can drop that ball out and then possibly pop that...

    Yes sir it is the floor shifter. I believe that the shift forks have become stuck together but there does not seem to be any easy access to the compartment

    2008 cat 420e backhoe stuck in first gear

    No Sir, On my machine that lever would be to change direction between forward and reverse . The lever that we are having trouble with would be the gear shift lever described as number 11 on your diagram. It has a standard "H" four speed pattern and the difficulty is it would'nt go into second...

    D3B Track tensioner

    Thanks for the reply BLS. I am not qualified to post a picture but I have children that are . When one of them comes in I will have them do it. I did however remove the Idler last night and I did have fair amount of trouble getting it out because of binding. I have a perfect view of the seal and...

    D3B Track tensioner

    Thanks for answering Dodge. I have removed all of the surrounding sheet metal and cleaned up every thing around there so that I can see into all the nooks and crannies. My serial number is 27Y3204 > It is an odd coincidence that is also the engine size. I believe that I might have it figured...

    Cat d4c hystat stopped dead in it's tracks

    Well folks ,We had the experts out today and after 3 hours of trying to keep this an electrical problem . A pressure check has indicated that it is a probable coupling failure.
