    Komatsu pc50uu-1 Tracking issue

    Update....It seems that the acceleration pedal was stuck engaged. When I pulled that out, the swing was working normally(same pump powers swing, blade and accelleration)...guess I should check the blade and track function now that I figured that out....

    Komatsu pc50uu-1 Tracking issue

    It seems that both tracks behave fairly similarly. Not much power when only one lever is pulled, but fine when both are pulled and in either direction. The travel acceleration seems to have an effect on speed. When both levers are used it can climb a 20% grade(estimated) without isssue. The...

    Komatsu pc50uu-1 Tracking issue

    I'm going to check, but I believe it was both directions. This machine has 3 hydraulic pumps and 3 valve blocks. One pump/block does swing, travel acceleration and blade. One does Boom, boom offset, bucket and Left drive. The final one does stick and right hand drive. If any of the pumps...

    Ford 555 hoe transmission oil leak

    Thanks Mitch. I'll give it a try. Seems like I should remove the filter housing rather than try to pull the lines out since they are hard lines from end to end. I'll see how much they move and then make a decision. Thanks again. Keith

    Ford 555 hoe transmission oil leak

    Hi All, I was hoping someone could give me a suggestion or two. My hoe sprang a leak as evidenced by the trail of fluid all over the ground where I had driven. Luckily it wasn't much more than about a quart before I noticed it. Upon inspection it was coming from the trans oil filter area. I...
