641 Power Steering Question

J. J. R. · Mar 21, 2017

I recently bought a gas 641 Workmaster. First I rebuild the whole front end from loader work. And now I just finished rebuilding the power steering box with new seals and expensive sector gears. The old gears were damaged from the previous owner running the box dry. Before rebuilding the box, it steered rather hard to the left. It now steers allot better. However it steers easy when turning slowly, but gets harder the faster you try to turn the wheel. Is the pump weak, or is there another problem with the power steering console?
Thank you for any replys

It could be a weak pump, slave cylinders leaking internally, a control valve in need of overhaul or some combination of these.

Lots to consider. Where to start? Guess the cylinders would be a good starting point. Thanks Dean.

If mine, I would start with the control valve.

Just about all of them need overhaul.

Do you by any chance know the part number of the rebuild kit for the control valve?

Thanks

No, but they are readily available.

Should be easy to find.
