Rich , I had trouble on the tele cylinders for the mack only do to not enough time on them
(rushing
) what I have now acctually works better anyways . I'll be making these ( walk in the park ) I even found actual wiper seals that'll work for the size . I have a couple pumps from index to play around with . 2 have motors on them . the problem with these is the magnetic coupling which is no problem to change (again , lathe time
the mill always is ready for more work for some reason
) ) I still have a sickle set of gears like what the jung pump uses , that I need to make a housing for .
