I was looking through this forum and saw a picture of the frame-hydraulics-bulldozer blade that is on a D2 I have been working on. It had a no. 5f3059 . So I wrote it down -after seeing it a few times I thought that is a good one . I hope my wife don't find that -she will think I need help. Ok now I need help. On the D2 5u5542 I looked into the main clutch I found that one pair of links are missing-7b5701-pin was in the bottom so I fished it out -can't seem to find the links. One pin is on the collar with both cotter pins. The ? is should I replace just the one pair or do all 8 so they will be the same? Thanks for any help.

A proper operating clutch should have all the parts and preferably have even wear in order to hold alignment during operation. If the pin holes are hogged out where the missing links are you can not expect optimum operation. Will it work by just replacing the missing links......probably. The only way to recover correct operation would be to replace all the links, pins, the hub and possibly the release levers.

I am posting to tell how I made out with this.I bought a whole new set of pins and links to replace them all. After hanging over the levers for quite a while with one hand in the clutch compartment chasing cotter pins around and around,I got the one replaced that was missing.My ribs hurt for a week after that .It was not looking good as far as removing and replacing the rest.Then I got into the left steering clutch project and with the final drive off it looked as if it would be a good time to do those main clutch parts.It was much easier-and I had an idea to keep the pins from turning as I spread the cotters-I used a little thread locker on the heads .It worked very well and all are replaced.I got the left steering clutch done and the final drive back on.replaced a broken equalizer spring and got the track frame back on .My boys helped me with that on Sunday.Now to put the track back together

Well, your making good progress:)
Thanks for the update.

I see the leaves are all gone!
Ours are changing rapidly!
Glad to hear the steering clutch project went well!

Old Magnet,thanks for being on the ball,answering all the important ? s that come up. drunjin,I am sorry to have misled you,that picture was taken last fall when I first got the D2.We still have leaves on the trees now. Another expensive lesson learned-I stripped the threads in one hole putting the final drive back on.The one down by the brake cover.I bought a helicoil kit and got that fixed.The Farmer
