I’ve got a 2008 D6T dozer , I bent my lift cylinder rod without noticing and kept on working scraped shavings out of cylinder rebuilt both cylinders dozer worked fine for 100 hrs aprox then blade would lower slowly on it own, so I suspected a shaving being stuck in the valve, I drained the oil from hydraulic tank took the valve out cleaned it, now my steering is dead, pump won’t even whine I tried bleeding it with no success help please thanks in advance
