Looking into options on adapting an M939 series winch onto an M809 series 5 ton. Reservoir, PTO, Pump, Hydraulic lines,Drive and Winch. First off the M809 winch from what I am reading is the same as the M939 series... Correct? if so I need to adapt the Spicer driven PTO to drive the hydraulic pump... Is this the way it is done? Or do I need the rear transfer case PTO nomally found on the M816 to drive the pump? With all the winches out there this has to have been done countless time but cannot seem to find a thread that covers the details. So before I over think this can someone point me to what is needed?
Learned from other threads:
1. Not all M939 series winch components are the same:
1.2. Two different M9393 PTO units, one with a removable plate that helps with the backlash adjustment and each has a top bolt that is tightened different.
1.3. Multiple mounting options, One where the Hydraulic drive is directly coupled to the PTO winch and one where the Hydraulic drive is mounted rearward and then coupled to the winch by a driveshaft.
1.4. There are different lengths of driveshafts when they are used.
2. There is a feeling that the hydraulic driven mode allows the winch to exceed 20K as the top "rating"
3. There are multiple reservoirs and mounting types.
On another note in trying still to buy up an M813 already with a winch I have noted that the shaft is broken or missing. I am guessing this is due to the winch being seized and the shaft busting trying to turn it OR the unit was overloaded and twisted off the shaft... any input on this? So part of the reason for my questions is if I purchase an M813 with a winch that is busted or inoperable what my possible options are.
