I have a 1989 Peterbilt 357 Concrete mixer truck that has a worn out 8 yard mixer barrel. I am thinking about making it into a 10 wheel dump truck rather than replace the barrel as all my other mixer trucks are 10.5 yards. It has front crankshaft mounted hydraulic pump that runs the mixer bowl. Could I use that pump to power the ram for a dump bed rather than buy a trans mounted married pto/pump wet kit? Has anyone done this conversion? Any info would be appreciated.
