Thread: Pto winch

Hand crank option was available for extra cost on the Thomas 8000ld winches in the early 80's. I know because I bought one with it. I thought it was only on the electric ones but is possible you could get it on the pto one. Thankfully never had to use it, hand crank that is.

Hi

I've a Thomas PTO winch hooked up to an LT85 5 speed. I have the crank handle it fits over the shaft which runs through the worm gear box under the winch.

If you have this you should be able to fit an crank handle. I have used, its easier to turn being a worm gear drive, though its as slow well as a worm, I'd get one for the extra security.

You could add a socket to a convert fast handle on a socket set too I'd say, carefully grinding some two divets on the end of a socket that fits over the shaft. Then attach the fast handle to that

or maybe a cordless drill

the winch safety for the perentie PTO is a ball and spring loaded ball ratchet torque limiter.

What it does

If these loads are exceed, the spring loaded ball ratched is activated separating the drive line from the winch. Once the excess load is removed, the torque limiter resets itself and winching can resume

the drive plate is has a series of "dimples" drilled into it and the driven plate has a series of springs that push balls into these dimples. When the amount of torque from drive line is too high and the winch is over loaded the balls overcome the spring pressure pushing them into the "dimples" and the balls ride up into the driven plate and the drive plate rotates and will continue to do so untill either the load is reduced OR the torque applied is reduced.

Continued operation of the mechanism in a slip condition causes the balls to wear grooves into the dimples making it easier for them to ride out lowering the slip point.

As the winch is a Worm drive configuration failure of the clutch will not cause loss of control of the load.

Quoted from the 102 and expanded on in Layman friendly Farey speak.

I don't understand how the sparkie winch would be any simpler in operation or reliability then a pto winch'the pto is variable speed and only requires the engine to be running to operate or a hand crank lever.it only take one wire to break or not earth properly and the sparks stop.

How far could you winch out of a bog with two batteries and no alternator?

Sure a PTO is sexy and all and if one fell into my lap I would go to the hassle of fitting up the driveline etc etc etc. BUT they are not easy to find, are slow and a little hasslesome to fit up (just ask Weeds).

5 years ago I plonked a cheapy tigerz 12ooo in the defender bar. Took less than an hour to fit. In those 5 years time it would have winched me or other vehicles hundreds of metres and out of grief too many times to count. Have overhauled it once (pulled down before install to check grease and sealing) and replaced the solenoids once. Never let me down. I call that KIS.

Hi

Depends what you are doing a PTO winch once set up is a working tool on the car. They almost seem to come form a farm background, working all day, whereas the electric ones are short use only.

Where a PTO is a genuine advantage is on hilly terrain where long hauls need to done and/or a lot of cars reduced pulled through.

I have a PTO, but if just playing around in the mud I'd go electrical next time round.

That said if you have to do a couple of 50m+ hauls up a hill, PTO hand down.

lol as steve points outs......i wont be giving my pto up

i have never owned or used an electric winch, i have used PTO's on and off over the last 25 years

just trying to think whats different to an electric

- another place for oil to leak from
- had to manufacture a cradle (nothing off the shelf)
- modify front bar
- had to fit new exhaust due to winch drive shaft
- pretty sure the drive is now the lowest part of the drive train, i could rotate it a bit
- replcing a shear pin would be take some time in the bush.....infact i dont even carry one
- engine has to tbe running

umm not sure about being slower........i must challange a sparky one to a race, i reckon using fifth gear no load i would win, fourth gear with the revs up would also be pretty quick

as said i would swap mine.....because ts different just like the defer its attached to

i agree an electric winch would be easier to install.

Just went and had a look, my Thomas 8000lber has a crank handle attachment too, i'm pleased to see. Seems to be more with than without.
