Ser # D5NAAKD 00261, 4970 hours, Running in Florida sand, marsh/swamp some, Replaced everything on bottom at 4550 hours, all ITR parts from Heavyquip out of Dade city, at 200 hours into new bottom had right rear idler start screaming, they furnished a replacement and 200 hours same went again, once again furnished replacement and I installed, now has 4970 and left front is out, seems [may be in my head] like every time right after playing with gators in swamp mud then this happens, wondering water intrusion into bearing b/c bad seal? Has anyone got any ideas? Run chain with some slack, have been pulling on wrenches on yellow iron for last 40 plus years and have never had/seen this happen, picture shows left side which is where front idled is shot, tracks in picture are l little tighter than I usually run them as had to take up slack and finish job today and bring it home, thanks in advance for any suggestions.
Ran into issues like that on the early Dresser H series dozers. The rubber rings in the seals were changed into rectangular shaped pressure rings for all the rollers and idlers. Dresser would only replace as fail and never admitted that there was ever a problem. You might check oil level in the shaft next time one goes or even pull the seal carrier off the end of the shaft for peek inside to see what is happening. Just don't give them an excuse to deny a warranty. Good Luck!
Well just found out you were sure right contacted ITR and they stated ''there was a bad production run''' further stated no way to tell till idler goes out, seals were not holding, cheeezzzzz......welcome to Taiwan America, please get us back to the old days and old ways................15k for new bottom parts and so far three idlers bad
They admitted their fault they should pick up labor cost.
They should but funny ending they presented me with a pro rated bill for new idler, we discussed labor on 3 replacements and they left, what a world
That would be my last time there.
If you read the warranty policy you will likely see they only cover the original part and not any subsequent losses relating to the failure of the part. Labor and down time are usually never covered when dealing with aftermarket suppliers. That's the screwing you get for the screwing you got!
