1984 Lahman Big Dipper 20

Looking at purchasing a Lahman Big Dipper 20, Wisconsin engine...motor runs, no hydraulics. Owner said it was very sluggish so they changed the filters, worked great then went back to running sluggish then no hydraulics.

How big of a pain in the butt is it going to be to replace the pump? From reading up on it, there are replacement pumps not too badly priced.

If it worked OK for awhile after changing the filters I would guess the oil is badly contaminated!
