Hi
I've got a cherry HD-6E crawler that has the blade hydraulics running off a rear PTO hydraulic pump. I want to change to a front(engine)mount pump. I am looking for the front pump, mount, coupling, etc. I have the turbo'ed 6000 AC engine.

Thanks for any help out there.
Rick

Hi Rick. Do you know if your HD 6 is an agricultural model? These machines had a turbo on them, but from my knowledge the regular HD 6 dozers did not. Since the Hdy,. pump is on the back, is the dozer attachment an add piece of equipment or is it factory AC. I had an HD 6EP dozer. Yes, the pump ran off the front of the engine, but this was all incorporated with the hard nose which has the dozer cylinders attached. The blade controls were also in this area. If you can, Email me a picture. I'll try to come up with a few places to get parts. I can send you a few pictures of the dozer setup if you want. Let me know, and I'll try to help you out. Happy Dozin' Phil

Thanks for the info Phil.

Yes, it is an ex-ag cat with the turboed 6000 engine and wet deck. Engine clutch in oil and power assist to track clutches and brakes.

The current set up is an after market one, not factory but it is very professionally done. I am thinking of using the current pump if the rotation is correct as the increased speed from running off the engine will only increase the flow, not the pressure, right?

My current problem is slow reaction time with the blade as I usually like to idle down the tractor when I do grading, etc so the pump is way below 540 RPM. Then there is the clutch problem..... no blade use if clutch is disengaged since the PTO needs clutch engaged to work.

Any pics would be appreciated as are your comments. Engine in this baby is as sweet as they get. One small squirt of ether at Zero degrees in winter is all she takes. 20-30 degrees she needs nothing. In this weather it will start like it was shut down a minute ago. No glo plugs, no engine heater. Just me and Allis. I love her of course.

Thanks again
Rick

I will try to get a pic but she is not at home for a week or two so will be difficult.

She is a bit over powered for the weight too. Breaks my heart.hehehe
