Always wanted a d6r
Hey, guys , something about dozers... a machine that age probably went through a lot. What raises my eye brow is that dozer blade seems to be from a long track machine.... LGP´s wich are usually used in sand... that would explain the wear. But who ever bought the tractor new, might have ordered... -

Caterpillar D6R Loss of Clutch Pressure
The PV sort of does not direct oil... it does cut off oil ... wich is not the same thing. I just don´t understand what is a solenoid control doing there... as that is suposed to be a safety feature and u can see my point. Maybe u can try run the system with the said solenoid at the X RPM... -
D6R modulating valves repeatedly sticking
OK, i though so i heard around that, that gear is timed, but that maters litle. Probaly u have to wigle the pinion or unbolt the steering motor so the gear goes up to place so u can slide the shafts... be aware shafts have a trikky assemble. In clutch steer machines one can get out the shafts... -
D6R modulating valves repeatedly sticking
Its a Diferential Steer system or a Finguer tip control? Understood u´re having troubles with the drive bevel, probably cause the bevel is not seated on the pinion, then u can´t push the shaft in, correct? As of me never worked on one like that, but that did not born as one!!! -

D7h transmission pump clearances (power shift)
Hey, I´m not an Hydraulic expert, but had my sort of problems solved. Something does not add up in your post as a series H machine should have a piston pump for main hydraulics. Nevertheless, with a gear type pump, pump condition can be visually ascertain, in case u can´t ID scratches and... -
D6R SHIFTING PROBLEMS
BTW, how can u hear grinding in the TXM? thats quite weird without visible destruction, sure all TMX gears are sound? planetary, sun gears a outer rings? also the needle brakes? Did u guys look at P1 and P2 pressures? -
D6R SHIFTING PROBLEMS
Well, if u already have the TXM out u can test TXM piston seals with compressed air. Or u simply invest in the future, reseal it!!! make sure TXM is not the problem. Press to the TXM system goes from priority valve. So u can tap at PV or on the rear where oil enter TXM. I´m not sure where... -
