Caterpillar PUMP strange problem, damaged pump two times ???

lundi 26 décembre 2016

Hello everyone,

We are expecting problems with the hydraulic Vane pump of a CAT wheel loader. We have changed it for two times about every 1000 working hours (from the last change) because it has structural damage mainly in the rotor and port place seizures. Pump number is 146-5076 and serial number of the truck is 3BS00338 of Caterpillar 962G.

Can anyone please help in determining what can be the problem that damages this pump. Pump has been changed from Caterpillar official dealer with original parts?

Thanks in advance
