I'm a long time Cat owner with 10 machines. I have recently had 2 Cat HEUI pump failures, and was wondering how widespread this problem is. Cat 324D failed at 4000hrs, and D6R series 3 at 4800 and again at 6800hrs, forcing pump and injector replacement.
According to the dealer, Cat have been attempting to fix the problem by upgrading the bearings in the pump, but the upgraded pump on D6 only lasted 2000hrs, so they still don't have it right?
Apparently, the bearing starts failing, shedding metal into the oil and then into the injectors.
They talk about the need for the highest grade engine oil, and engine warm up procedure, but it would appear these pumps are causing widespread issues.
Has anyone else got similar history? If so, why don't Cat own the problem and help their customerss out, till they can sort it. In my case, if it's out of warranty, I pay the bill.
Gotta admit, I expected better of Cat than that.
