Undercarriage cost

Looking at doing a complete undercarriage on my D6c and was wondering what a ballpark cost should be.
This is for Korean salt chains, sprockets, idlers, top & bottom rollers. Using old track plates. All installed by dealer.

Im going to guess somewhere around $10k.

I suspect those numbers Parts ONLY. For UC, have a tech come out and inspect, give his $.02 as to what NEEDS to be changed and WHO to buy from if want the UC to last. Buy a GOOD torque wrench if do not have one and heavy tools if changing yourself. Having someone do it expect a MINIMUM 40 hour bill. Segments, rollers, Rails and Shoes, idlers, where track adjuster cylinder rebuilds, broken bolts will be extras. Cat Classic will be a Lower figure, a dealer likely will not offer aftermarket supplies.

That sounds awful light. I'm guessing they won't pull the track frames and turn them over. Won't align the front idler with the track frame, won't check the equalizer bar retainer pads and won't check the alignment of the track frames with the sprockets. Did you talk to them about broken bolts? Does your machine have rock guards? If so are the rock guards welded to the frames? Do the roller bolts have straps welded across the bolts? How about rebuilding the track adjusters while the idlers are out? Are your new idlers complete with the end blocks or do you have to be dismantled and put on the new idlers? That amount of money is usually about the cost of a D5 size machine by a Cat dealer.

Trek or another brand? Would be good to have a detailed quote with everything listed separately and what all is charged extra. Then you can see what else may be needed such as rebuilding track adjusters.

Quoting KTR chains I believe. No rock guards. I rebuilt track adjusters not long ago. Not sure if idlers are complete unit or not. Before I go ahead I'll get more specifics.
Sounds like it's not too out of line if it's done well.
Bottom roller holes have been drilled to ¾"..... apparently the orig. rollers with ⅝ bolts are hard to get and are more expensive.

Nice, sounds like you lining up the right questions to ask. Let us know how it turns out.

Probably won't get it in the shop until late November. Neighbor just asked me to push out about a mile of fence line. Of course it has lots of nice big elm trees in the fence.

I went down that road in 2017
Complete Installed
SALT trek, hardbar,wearstrips, adjusters, no broken. 15k
HD cat same as above 25k
Every once in a while a blind squirrel finds a nut. Tossed engine D6 with a complete 300hr berco. Did it myself over the winter. Been good so far in mixed dozing and scraper use. Id look into the ITR stuff. The big muck shifters over the pond run those on the 8K's with pans.

Knowing what you know how to do. Pull the frames and do it yourself, easy job to pull the frames. Your hardbar mounts and the frames and under the tractor will be trashed. Use all caterpillar fasteners, super strength bolts for your mounting hardware.

Putting non oem tracks on this old D6 will be a good idea.
There are many undercarriage parts available here in the UK.I’ve tried them all over the last 30 years in D5 to D9 tractors.
It’s hard to make direct comparisons and everybody has their own opinions.
Consider price per hour rather than quality for many applications.
My favourite tracks were Berco for my D8 and boxes back in the day.Not much cheaper than Cat,but they seemed to last forever on drawbar work.These days I steer well clear of Berco as I hear nothing good about them from others.
DCF and DCR,I’ve fitted a set on a D5H and a D8H that are part time tractors.They were cheap and not particularly good,allthough I had no issues with them.
ITR....these seem to be a fair option for me these days.The customer service is great and the wear on them has been pretty good so far.
Their GET products are priced well and we actually get more hours out of their blade edges,bucket edges and ripper shank gear.They are generally a third or half the price of Cat.
ITM.....the most cost effective hourly running costs I’ve enjoyed from any undercarriage manufacturers,allthough they went bankrupt in December in the UK,so perhaps they were too cheap?Eitherway,they make a great quality product for my D5 and D8 tractors.
FYI,my current ITM trackgroups fitted to a D8T needed to hit 700 hours of running before they were level with the Cat track groups cost per hour.They have managed that with ease and have 35% wear on the bush,so they will be pure profit after this time unless they snap and cause damage(never say never).
Astrak......they seem quite new to large tractor undercarriage parts and I’ve bought new sets of rollers and idlers off them.The proof is in the pudding as they will sit in a container for some time as I don’t need them.
Their customer service is absolutely sharper than a razor and they are priced in line with ITR,so only time will tell....
Cat....well,every so often I bite the bullit and buy Cat undercarriage.I should give up on them really as allthough they are a great quality product,they tend to double my hourly running costs.
I’ve tried them all from Cat HD,PPR,GD and???I get confused with all the options.I’ve never tried system one yet,and there are many contractors swapping back to conventional tracks for their D5 and D6 tractors.I should also point out that it’s Cat’s competition that’s getting those jobs as Cat are at least twice the price and take much longer to do the job.
Failed parts.......in 30 more years,I recall no problems with Berco at all,but that was then.....
ITM,I’ll admit to one failed new D5 idler that was replaced by them the next day.I’ve also had 3 collapsed bottom rollers,but they were at the end of their life anyway.
ITR,no problems ever as yet.
Cat,A handful of sheared D9T segment bolts fitted by someone else on 3 seperate D9’s.Replaced with Cat bolts by myself with no further issues.A few broken Idler bolts on D8R and D9T tractors for no real reason.I don’t hold Cat to blame.Could be a mix of bad driving and bad fitting?.
Last of all,a sheared idler shaft on D9T.Finnings didn’t want to know at all as it was 30% worn and arrived on a tractor we’d bought,so it seemed a good idea to use it as a door stop.Finnings wanted nearly 3k for it and a few weeks to get one during Covid.
ITR wanted 1200 quid for one and about 3 days to get one.
Got a DCR one the following morning before 6am for 1k delivered.Its currently done over 500 hours and looks in good shape.
The moral of this long and boring post is to look at your own hourly running costs and the type of material you work in.
Would I put a ITR undercarriage on the D9T if it was working in hard granite?.Probably not.I’d stick with Cat PPR.
Would I put Cat on my old D8H or new D8T that’s not in hard rock??.Absolutley no way as it’s far,far too expensive per hour.
Do your homework,you may be suprised at how economical some non oem track manufacturers actually are

My ears always perk up when I hear someone talking cost per hour. You can't talk about it unless you have measured it and you can't measure it unless you have actually run the machines. It takes the wind away from the blowhards, book readers and snake oil salesmen every time.

Thank you Nicky 68a for your post and information.

Don't forget the "oh by the ways" that you will find. Doing a full undercarrage on a JD 450C and upon disassembly found that I will be replacing the rock guards as well. Found that they were cracked and in one place badly worn by a wayward track roller.

The manual very specifically states that the rock guards should not be deleted as they add considerable strength to the carrier frame.
What they add is considerable amounts of clodded dirt and small rock that your rollers and rails constantly grind against and wears your undercarriage out twice as fast. They are bolted on and have little to do with strength of the rail frame....but you do what that manual says.
