I have aquired an old D7 17A dozer, the blade is driven by a direct drive cable winch on the front of the engine, was working fine last fall, and then it just want to raise on its own all of the time and i cannot get it to go down, from what i have read so far, sounds like the clutches have piled up. Does anyone have any info on how to repair, or where i could find some parts for the old girl? Thanks, Shane
Start with checking adjustments.....
Don't do these adjustments with the engine running. A Cat safety film I had to watch in my teens showed a gruesome result.
Was it called “The Gambler?”
Geez mate, now you're asking a very difficult question. It's got to be 60yrs ago. The film was about adjusting all Cat CCUs.
I never knew Cat had a cable control unit mounted to the front the machine. Guess I never saw one since the blade would generally be blocking it's view. Was it direct driven by the engine from a shaft on the crank pulley that went under the radiator?
U bet
It’s direct drive from the engine, but dumb me not thinking, the 3/4 bolt in the center of the winch is left hand thread, ( maybe I said that wrong, but I had to turn to the right to loosen). I’m thinking I just wasted a winter of waiting to fix, but I think now I can set all of the adjustments and should be fine. Old Magnet, thanks for the pic diagram, I hope this was just a good up on me, but the winch turns freely now when I loosened the center bomt
