Convert a PTO winch to be electric driven

Thanks for that. looking like a goer.

I don't think it matters what side the shaft comes out of the winch body you can make it spool correctly by changing the direction the rope comes on to the drum. How did you get the bull gear off the winch main shaft? i've had the end plate off and the bolts out but it wouldn't come out, i'm guessing its a press fit

bull gear?? you mean the big brass/bronze gear its a very tight fit flat punch and a hammer carefull not to flare the end of the shaft out

thats a copy of the manual or the winches its a multipage image only somet programs can view it correctly

thanks mate

Load sensed variable piston pump is what they would have been talking about. Good stuff but costs could quite easy get outta control. Variable vanes pumps are about, but by design are usually used in low pressure systems.

Cheap and simple gear pump run of your existing PTO, basic solenoid valve or cable controlled manual valve and mount motor to winch. A bit of careful design and mounting of the oil tank and a cooler may not be nessasry.

From the $$$ you were kicking around, the hydraulic setup could still end up in the same ballpark.

Actually now that i think of it, the reason it came up was that a normal gear pump was ok for general winching but for competition use a variable piston would allow you to increase the volume/flow regardless of the PTO drive speed. Which is important given that if the flow on a gear drive is directly related to the PTO drive speed it's the same as having a shaft running to the winch. It means that if you drive assist then you'll over run the cable and birds nest it. With the variable piston you can drive assist and as the load comes off you can increase the flow without necessarily increasing the PTO speed.

Some of the comp vehicles in rain forst challenge were using Diffs welded up and cut down of the PTO drive so thay can winch and drive at the same time no real break system on them that a can remember.

suicide winches are totally banned here in oz comps.

i think some of these run off one side of an east-west motor/box combo, mounted north-south (the other side running to a divorced transfer for heaps low gearing).

Crazy shiz...
