hello gents,

I have a 955-12A and I was working it this weekend. It is a great running tractor.. I took a break and when I went back, i noticed that a pin in the track had worked it's way out about a third of the way, enough to come out of the inside link.

i was able to get it back to the garage and have tried to align the track so that i could try to hammer the pin back in..

well I tried for a couple of hours with the link in various positions and with a come-along and pry bars, etc... no luck.

I am assuming that the local cat dealer would have the equipment on their services trucks and would have the pin back in in short order.. what would a call out service call be worth for this sort of thing?? i will be calling a dealer today, but wanted to get an idea prior, so that I would have an expectation of the cost.

thanks

Hi Rod , Did you back the track adjuster off to take the tension off the chain ?.You may need to take some track plates off to get a good hit on the pin ,with a good BIG sledge hammer ..Line it up as good as you can and put blocks of timber accross on the other side of the track chain to brace it and try and take the recoil out when you hit it ..If it does not move after a couple of well placed hits , ,you may be better off driving it out to inspect the pin to see why it is not going back in .

ianoz,

thank you for the suggestions, I hadn't thought about taking the plates off, but will do that for sure.. I had thought about taking some tension off of the track, but hadn't done that yet..

is there any particularly "better" place where i should have the pin?? on the front idler, for example??

Some say Idler ,others say sprocket . Myself depends if your right handed or left handed as to which way your more comfortable at swinging the Big hammer .

I contacted Milton Cat once recently about a service call. fore one days service call it totaled about $1100 by the time you added travel time, mileage, and field time. :jaw::jaw:

HI RDITZ For putting back the pine in track the best place is back sprocket and live the pad on because the link will open and the pine will skyse in link and with a hydrolic jack you push on the bottom pad until you have a good pine enlignment

Definitely back off the track adjuster first or you'll probably never get that pin to go back in. I'd guess that pin came out to the outside. My favorite place to work with 'em is on the sprocket. Brace the back link with something solid so it can't move (I use a 24 ton hydraulic jack). Pads on or off is a matter of choice if you have a chunk of something long enough to drive the pin with.

OR. .you could finish driving the pin out and replace it with a new master pin. I have several 1/32-1/16" undersized pins that I use as slave pins. Put it back together with a slave pin, then drive the new master pin in while at the same time pushing the slave pin out. Also a couple of big clamps can come in handy to pull some slack between the links in the chain.

If it came loose once, it'll probably do it again so a little dab of weld might be in order.

thanks Hector and ol Grump.. we got snow last night, so will have to wait until that melts and everything has dried up a bit.. probably on the weekend will get another chance to look at it..

agreed that if it backed once, it will do it again, so i had planned on putting a small weld on it to keep it in place.

thanks again, will report back with progress once i've gotten back to it.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
