Hydraulic pump

badger bill · Oct 19, 2014

Can anyone help? Ive posted the question twice and no response. Im rebuilding the Hydraulic pump ( 180920M1 ). The manual shows a valve seat tool that does not seem to exist anymore. Can someone advise me on how to seat the new valve without this tool, or is that needed. Also the control valve looks good, but should it be replaced since I'm there.

BB, My manual doesn't seem to show such a tool for my TO30 or else I'm looking in the wrong place. I suppose any type of hone that would clean up irregularities in the seat would help a little but, absent a crack or other void in the seat the pressure probably deforms the valve disc enough to prevent regurgitation. Most folks recommend replacing the control valve only if there is significant scarring that would allow leaking. The safety valve is another animal though - $30 or less in most on-line shops is cheap insurance.
