OK, all you cats running Nissan PTO winch's, either in club trucks or comp vehicles, tell me all the things that go wrong with them, and all the things that need to be beefed up or made differently to make them bulletproof and fast/strong. I have one sitting on the floor here, and it'll become another SNR product soon

I havn't broken mine yet, but when I change the oil in the winch it always has alot of brass in it . So I am guessing the brass/bronze gear inside must wear quite abit. Other than that I cant fault it.

Most of the winch challange competitors that run the PTO winches usually tend to go through the PTO drives quite often... as they get a hard life and have only small gears.

Worm gears? (I think)

Jafa,
To save me replying to your PM and for the benefit of others..

Don't know that steel worm wheel would be much good. We've used bronze alloy before to reduce amount of wear but doesn't have any "give in it", so can't see steel being much better.

PTO output is fragile. Has a constant driven gear whcih goes into the gearbox and breaks when overloaded. A few people have tried custom ones, hardened etc...still breaks. We've never broken one, but ours is religously maintained...and then abused in comps.

If overloaded, the input worm gear into the winch will push out the bottom of the housing. Housing is only cast alloy. Again, we've never broken one.

Bearings (x2) on the input shaft to the winch fail. Available from Seaco.

Collar on freespool end cracks next to grease nipple.

They are too slow to be able to effectively winch and drive (when you've got enough traction to be able to drive on), so you end up over-running the winch.

Using the correct high temp oil for gear types is essential.

We make a wider steel drum (capacity for 75m of 11mm dia Amsteel Blue) and make a freespool which a few other comp guys use also (Justin Wynyard, Roger McKay, 4WDBits, Simon Guy etc).
