    Default Anyone ever pulled 955L clutch off bevel shaft?

    Ive been working on an old cat 955L i recently purchased. The nut that tightens on the thrust bearing snapped off and i need to get the clutches off the bevel shaft to get to it. Going to change clutches while im in there. The advice on the other forum was to hire out someone to pull the clutches off the shaft as the manual calls for adapters and step plates to pull it. So far i have been unable to find anyone to do it for me. Any way i can farm hack this thing off with a floor press without screwing it up? Any other bright ideas or advice?

    If anyone is interested i have been filming the process of working on the machine. Dont have all the videos up yet but will soon. Here is what i got up so far.

    A puller fabricated from a heavy piece of plate with two holes to fasten it to the steering clutch hub with the 5/8" bolts,with a large forcing bolt to push on the shaft, will work. Don't forget your big hammer.
    You'll need access to a press to push the hubs back onto the shaft to the correct spec.

    Heh

    Being a “farmer” myself as well as CHEAP, my first CAT experience involved R and R of steering clutches. I fabricated a puller utilizing a 10 ton porta-power. With a little heat and a BFHammer, I got the clutch packs off of the shaft. Pressing back on is recommended, but the old time mechanics I know swear a person with the proper skills can get them back on tight enough, without the 30 ton press?
    Thanks for the YouTube videos. It always looks easy when someone else is doing it! JM

    oh man i should have checked back here earlier, i already took it into a shop to pull them for me. From what you guys are describing, i bet i could have got it off of there. I did go to harbor freight and buy a 20 ton floor press so i can pull the clutches apart. Im assuming i could use the press to get the clutches back on the bevel shaft myself. Glad you like the vids JM, it has been a lot of work especially with it getting hot now.

    Get yourself the tool for the springs from General Gear. Pays for itself after the first set of clutch discs! Being “green” and never torn into such a project, my Service Man’s manual helped too. Best of luck to you on your repairs. More videos please! Lol. JM

    Default Clean Dry Clutch Hub Splines

    Hi Team,
    when you come to press your hubs on do not exceed 15 tons--we used to use 12 tons at The Dealer without issue as we still had a few split at 15 tons.

    I have seen several hubs that split if the splines in the hub and on the shaft are not 100% dry of oil or preservative, if new hubs etc.
    The old spec was 20 tons but there were many failures and Cat pulled it back to 15 tons max.

    When pulling the hubs it is vital to ensure that the puller bolts/studs down into the hub puller threads are fully engaged as there is a high risk of breaking the side out of the puller thread holes--seen it done several times over the years--gets expensive then like when pushing on too hard also.

    Cheers,
    Eddie B.

    That’s very good advice edb, book said clean and dry, NO lube. As for the threaded holes? I did exactly what I wasn’t supposed to do, as I managed to break a portion while pulling with my scrap iron contraption of a tube puller.....and please be extremely cautious when pulling apart, as I only had 10 tons worth, a bit of heat and my trusty #4 pound Snap On hammer....I had it in vertical position pulled upwards set on a heavy welding table, when it went, it reminded me of a spaceship launch. It only shot up a foot, but could have injured oneself in a terrible way. All of this to keep my local dealer from getting a few coins from me. LOL.
    I think the lad working on the loader is doing good by sending his out to be pulled. JM
