if you actually going to USE the PTO then factory sells a larger one, drill and insert. works very well.
the original size pin is great for a winch that isn't going to see application.

nail works well
bolt is great for those that PAY ATTENTION but will cause serious damage in unattentive hands.

I think std is 4.3mm and next size is 5mm.

4.318mm ..... :)
My only experience with shear pins has been on outboard boat motors but the theory has always been if the shear pin is substantially larger than what is recommended by the factory you are just going to break something else. Does that same theory not apply to a PTO winch?
 
i don't remember the size but i do know that when i ordered a new replacement from ENS, the one that came in was substantially larger.
 
:lol:
well, yes and no.
the PTO itself is VERY robust.
one young kid i know had a PTO on the front of his BJ70, he replaced the pin with a small bolt.
after winching out of a hole in Wiperous he disconnected from the tree, wound the cable in. got out and bragged how great the PTO is compared to the trusted 8274 ... jumped back in his truck and started to drive down the trail.
seems as he was driving away the winch was still engaged and CRUSHED his front bumper.

ooops

so, as i pointed out, IF you are going with something other than a sheer pin you best be attentive to what you are doing.

crap, is this ruining this thread? if so i will delete.
 
I worked on the PTO driveshaft today. I replaced all the u joints on the PTO driveshaft, and worked on mounting everything up. I used a 5mm bolt for the shear pin, which fit pretty well. The holes were about 4.7mm on average already. I did have to run a drill bit through the holes, but didn't take much material out at all. more rust than anything. I am a little concerned on the yoke that goes onto the winch. I'm finding the yoke is loose on the shaft to the PTO head - it has wobble on the shaft. Is that normal or is it typically a nice close fit for that shaft diameter? I don't want it to come flying off under load and wreck a bunch of stuff.
 
My winch head yoke flops around like a fish out of water. I hope it's normal. It will deflect very noticeably when you put sideways pressure on the driveshaft.

I suspect that PTO shaft RPM is actually not that high during operation. When the shaft is turned by hand the drum moves significantly.

yes, that is normal to have slop at the winch end. relax and enjoy

No not out of context. I have seen it done several times including pulling the hook through the fairlead all the way back destroying a bit of stuff with rear mounted ptos and front mounted.

Hand should never leave pro lever unless changing gears and then back to pto lever until winching finished. It's the rule I follow to not forget to release pto lever.

More PTO questions

The yoke on the transfer case end moves freely on the driveshaft. fell off a couple of times. The yoke end on the winch is splined also, but does not move at all. I assume it is supposed to move to allow some movement in the shaft.

Please verify. I will probably have to go to work getting it loose
 
i just pulled yet another PTO "kit" off a truck ... once again the splines are snug as well as the end to the PTO.
but not to the point you have to work it loose.
 
checking the voltage on my 24v to 12v converter, I have 24 going in, but 17+ coming out on the terminal marked 13+

Is that normal, or do I have a bad converter. I do not want to burn anything up!
 
i would have to say ... you got a dud.
usually i have 13 coming out.
but those more knowledgeable will have to confirm.
 
Just for grins, does your meter actually show 24v on the input side? If that number is also high perhaps your meter is wacky.

The meter shows 24.02V on the input side. This system has a battery. Maybe it is charging at that level. The light shows charging
 
That would rule out a faulty meter. So the converter is probably at fault.
 
I got this plate from landcruiserjunkey. Nice place for it on the ARB bumper. Going to use it on the front of the BJ74. I will get a personalized plate in the rear with the same number.

I might name the landcruiser Vic!
