Not to go against what you are saying I'm sure everyone has had some luck with this or that aftermarket undercarriage but I purchased a used 2005 D6R with a brand new ITR undercarriage that the dealer installed It didn't last 200hrs before pins started seizing and we lost a rear idler. I would never in a million years would replace an undercarriage with anything but a CAT HD undercarriage. YES YOU WILL PAY A PREMIUM but it will outlast almost any other OEM undercarriage we've seen thus far. I rely on my machines to carry the weight of my company and pay all the bills just as the tires that I put on our haul trucks to get these machines to their work sites I won't compromise quality over saving money. Usually in the end its the same amount of money less the headachesFWIW... I put ITR chains and sprocket segments on a Komatsu D65 EX-12 dozer. IIRC it has @ 2500 HRS on them and have been very pleased so far. A contractor/ friend is a dealer for TREK. He runs 4 dozers and has nothing but good to say about them. I will probably give them a try on another dozer that is getting close to needing a new bottom.
Other than your local friendly Cat dealer - no idea.I am inquiring at some of the suppliers listed above, but does anyone know where to get Systemone track shoes? D6T
I have been real pleased with ITR on my D6H ll. Almost 1000 hours with no visible wear on rollers, idlers or rails.FWIW... I put ITR chains and sprocket segments on a Komatsu D65 EX-12 dozer.
