Keep Hydraulic System @ Rated RPM

[3RRL]

The KAMA 554 has 2 pumps...one separate for the power steering. That is really the one I'm interested in reving up. Under normal loader use when transporting dirt in the bucket, I cruise to the spot for dumping and sometimes the power steering does not react unless I crank up the rpm's.

My question was to see if
1) it is possible to change to a higher flow?
2) if there is something out there already?
3) keep it simple?
4) or not worth it?..just increase the rpm's? (obvious solution, ha ha)

Thanks,

I'd look for a higher capacity pump... the excess oil is just dumped anyway..

it's mostly the way things are, unless you wanna spend gobs of money, on a system that's gonna take alot of room, alot of plumbing, and may have some odd quirks. some excivators and new equipment have varriable displacement pumps, and presure compensated systems, but they are $$$ equipment, and built for a guy who's running them 10-12 hours a day.

our 580 case, although an older machine has the same thing. if you want more power to steer, or faster loader travel, you shove in the clutch, and rev it up.

if its your steering. have you tried putting some weight on the 3pt hitch when doin loader work? it'll take some of the load off the front, and allow it to steer easier.

That's where hydrostatic transmissions really shine. The ground speed is independant of engine speed (except for maximum speed of course).

 

[Soundguy]

However.. PTO speed is still ratio-locked with the engine speed...

I would look into changing JUST the pully on the pump.
Surely you can find one to fit or make one fit.
You'll need to go smaller, just a little smaller than stock.

Well,
I looked in the parts manual and it appears that my pump(s) are gear driven. But you have given me an idea. Now I'll need to check if spinning the OEM pump faster will hurt it?
Thanks,

Thats what i would be conserned with. If it spins close to "normal" speed after you modifiy it at only 1500 (engine) rpm then it might over rev and cavatate at higher engine rpm.
