HD 11

Should be able to find some...there are 2 different choices based on serial number.....do you know which one you are looking for?

Copy that....well if and when you get some pictures and post them we could tell which sprocket you need.

Major Problem is will need to change All or None to make it any viable. Several have gone to locating 955 or D6 Sprocket rings or Segments and then changing out Rollers and that means redrilling frames, Idler can be revamped to accept 6.91 Cat rails where those will then outlive the machine. Are NO 7.0 pitch rails available US any longer.

Yup. BTDT. Lots of quality family time to be had when that happens! Tongue

I've not had the good fortune to need to do it on anything that small. I remember well a TD-25B tractor doing that track walking bit that down in a pit in December, 1980. Getting it back together to replace track release seals back at the shop was an "ordeal" at best for a 20yo kid working by himself.

That's All Folks!

This one had been walked clear of the sprocket at the rear and the pads were pinched between the idler, roller frame, and tractor frame at the front. Several bent pads too. Used my black and white B-61 with the 20k Tulsa winch/sheave block to pull the track free and jacked the tractor on cribbing with a couple hydraulic jacks to get the track actually loose to work with. Then used the winch in different positionionings to drag that heavy SOB into place to roll the track back on. And if that weren't enough, the damned thing fell over on me while winching so needed to roll it back over onto the grouser bars again. I must have been in, and out of that truck 20 times in that hour with all the rigging, pulling, operating etc.

Once finally positioned satisfactorily, machine power pulled it right on. They then drove it to the repair shop but I didn't do anything else myself.

Was let go at the end of the month to protect that tenured union operator's employment position though he was known to be rough on equipment and a PBR was part of his lunch break.

	No sir. I havent seen it in person yet. The guy that is selling it says the sprockets are still usable but will need changing soon. All this came up all of a sudden. Ive got 55 acres id like to clear to put cows on. Maybe a few acres tilled. Its got some wet spots so ive got to ask soil conservation if i can even do it

	Worst ever had was a D8 48A, rolled one rail off in a Dirt Recovery company site, as he was trying to roll that back on rolled other side off. Had to roll BOTH back on to get out of the Hole as flood of 1984 was on the way!! Used a Old Track Hoe also in pit for heavy drag work. Tractor ended up on cribbing for Segments DuoCone seal assemblies, trucks both off and all rollers both idlers resealed both tensioners and replaced both rebound springs, EIGHTEEN DAYS!!!! Bolts broke, had issues with anchor points wear, trucks ended at a weld/machine shop for three days of work. Poor old machine had been neglected FOREVER, fairly certain were OE Rails.
