I have a komatsu d65ex-15 dozer with around 9,000 hours. I’m getting hydraulic oil into the transmission. Approximately 10 gallons of oil in say a 8hr day. Anyone know what can cause this? Hydraulic pump shaft seals? Pump shops says they believe there are 3 pumps that are ran off the transmission. How do you get them out ? Through plate in cab floor? Looks pretty tight?
