Nissan PTO winch - winding the rope on the top of the drum

[4x4rookie]

Any reason why the winch rope can't be wind on the pto winch drum on the top of the drum as against the usual way of the bottom of the drum. Effectively reverse becomes forward and forward reverse ?
Just wondered if the spiral gears are set for one way only or happy either way ?
cheers

The winch can run from either direction... The gear is symmetrical....

However if you are thinking of using your rev for winch in when in a std truck you will run into problems when you want to drive and winch at the same time......

They will be going in opposite directions..

Doesn't the Nissan pto run off the input shaft so it wouldn't matter? Just need to put pto lever into reverse instead but you will need to raise the fair lead.

True I think you are right I am a toyota man .lol

Any Nissan men or women for that matter can clarify hahahahah

Nissan Pto drive goes in the same direction and speed no matter what gear you are in

You have more pull with it running under than on top, it's all to do with drum strength too they are not designed to do over pulls. I know have done a drum in this way

[derk]

the drum is just a cast cylinder and effectively symmetrical so reversing the rotation wont make the drum any less strong the thing that breaks them is the way you load them, as posted above somewhere you'll have to lift your fairlead so its guiding the rope to the top of the drum not the bottom and make sure your fairlead slot is narrower that the drum width so your not loading up the side of the drum as much and breaking it off when hard winching on an angle.... breaking off the side of the drum is a common failure

I've seen an electric winch rope wound on top, by mistake, put a heap more leverage where mounted to chassis and bent bar down, never bent when rope was out bottom pulling straight on mount. fairlead was for bottom feed though, might make a difference.

don't know if be any different compared to pto.

[coxsy]

mines always been bottom feed in or out,but the extended winch drum has bent the main shaft on winch two,winch one had no free spool moved the shaft outward have free spool, till bolted into the cradle ,cut the support angles ,bolt up the winch ,now have free spool ,welded the angles back up.
these winches to take a beating but there is a limit

[diogenese]

Like Mudsurf said, you increase the forces on the mountings and can break side plates or bend the chassis mounts. Bottom feeds keeps the cable coser to the mountings.

The pto mounts vertically at rear , so top or bottom feed makes no difference to leverage, unlike a horizontal bottom std electric winch.
The std drum is aluminium and the weak point is generally the sides or ends, the issue like I experienced was bunching of dyneema rope on the end put so much compression loading that the side literally shattered, In saying that would have lasted awhile if it hadn't bunched...The internal gears are symmetrical as said but I would strip open and inspect, you can reverse the main bronze gear as its likely to be worn on one face. Clean and put in the right oil ep400, rotate end plate so filler plug is higher means U can put more oil in it, run breather tube from top to somewhere high so it breathes, will get warm under lots winching, some even mount a remote reservoir of oil to increase total volume in system to keep cool.
Great winch, strong go all day..
