936 hydraulic speed

[colesmotorsports]

Got a weird one,ive got one wreck ive had for awhile.
Always hated how slow the hydraulic speed was ,everything slow. kick the pto in rpms go to 1500,put transmission in 1-5 its just slow. Got another wrecker 936 kick the pto in throttle doesn't automaticaly put transmission in 1-5 raise throttle rpm to 1500, all the back crane stuff is 3 times faster . Seems way to fast,put throttle back to idle and transmission in to 1-1 doesnt seen to slow it down. why is the one so slow and other crazy fast that cant seem to slow it down.

Flow. One pump is obviously weaker than the other. GPM = speed

Transmission has to run at 1500rpms or more or it will burn it up when a load is put on it.

Don't know it's really a big difference but dang cool, probably a pump or something???? I ve changed hydraulic oil, new filter. Need to put pressure gauge on it. The pump drive shaft spins way faster on the faster one . Think I red the transmission should shift through the gears up and down with shifter , not sure though.
