    Hello HEF, I want to put new rails on the old 931b, at first i was going to leave the old recoil on, but after second though, mabe i should replace
    both of them. Iam not sure if the springs are the correct ones anyway, when they are on the machine, leigth 19'' , and before compress 24''.
    Please let me know what you think, will the new spring be best.

    You have a missmatch there Sam. The first pic is too tight to work. Check the back stop for square, it and good fitting anchor slides keep the spring straight.
    Later Bob

    Hi Bob/Ont, I had off road ship a couple springs, it looks like the broken spring is the right size, the one on the left is too small, i hope to get them on when i get ready for new chains, from Brad in Tx.

    wosama931b----I replaced the springs and T,A,M on my 955L, as I was cautiously advised by some very helpful guys on the FORUM, PLEASE be very careful with those springs! especially when you compress them to assemble them. spring.jpg

    Hi Toddcat955l, I did see and read your thread on your repair, My book says to be sure to have a guard on the press, I plan to be careful and will try to find some one that can help with the press. My brackets look ok and straight, but i will take a close look at them after i get the re coil off. I will keep a post on the work to
    let everyone know how it goes, time for a short break in the mountains, back next week, sam.

    I had the nuts off the end of the recoil end of the retainer shaft, the wear on both was bad. I'am not sure about them holding the spring..and the exposed threads
    on the shaft are rough. can the spring be cut loose with a cutting torch?? take a look, sam.

    Wosama931b-- You can cut your springs with a torch, That's exactly what I did. I cut each coil and it just lost all tension. I don't think I would remove your big retainer nut from the end of the threaded shaft ,Until I had completely cut each coil. Not trying to tell you that its the safest are the best way to do it,but I did do that and it did relieve all tension on the spring. Good luck and be very careful.

    second that post from toddcat955L never underestimate the force of a retained spring.. if the springs are getting replaced safest way is the cut one, two or four coils to realise all the tension.. give it a hit with a hammer to make sure its loose before undoing the nut

    thanks for the advice,, the old nuts looked like trouble, i will cut the broken one first, and with it in the bracket on the loader, as you said one at a time, the old springs are not any good anyway, ,, Back to ya later, sam.

    Springs & hyd lines 005.jpg Hi HEF, I got the re-coil springs cut to remove the pressure, just need to get the pins out of the track, i think i may just cut them loose, i will get new chains and
    grousers anyway, or maybe heat up the link to see if that works. sam.

    Sam, I'm glad that you got everything apart safely. What caused your track bushings to gouge like that?

    Hi OldandWorn, I think that they just tryed to push to hard with it, also i noticed the pipe had wear to, and the spring on the left had 2 broken places.
    i guess they had broken the spring when it was compressed, because it was too large for that cat, LoL.
    I just droped off the parts at the Cat dealer, they will put a new pipe's, nut's, seals and compress to re-install. I'll post a photo before i install, sam.

    I think what O&W was referring to in his post are these gouges Sam. Are all the track link bushes like this or is the one in the photo an isolated case..?

    Yes, thanks for the circles Nige. Is that an area where the inside flanges of a double roller would be?

    Agreed - that's where the inside flange of a double-flange roller is going to be. The gouge seems a bit wide to have been done by a roller flange though.

    Hey Nige, That was from the old rollers, the flange was loose on a couple or 3 rollers on that side, i hope to replace the track after i get the re=coil spring back in place. The guy at the cat place said that the cylinder assem. had wear from the yoke hitting from the inside, so had to order more parts to be on the safe side if possible, gives me a little time to get the frame cleaned up and painted. sam.
