24V Warn 8274 vs. 24V Aisin upright - no load line speeds

[lulo]

That's a good mod to have, but how the hell does he drill the shaft?!! That is shaft is so hard - must have to go into a machine shop.

Weld a bolt on the shaft, is a tricky task to do, but cheaper

Is almost impossible turning the shaft, is a hard axis

Always amazes me that Warn still use a CirClip to hold the brake on. Plus the R clip to stop the free spool disengaging.

Another easy up grade to a warn 8274 12v is to switch the motor to the 6hp XP line speed is a little slower but more pulling power. Does require the winch in solenoids to be up graded too but you can squeeze them in the Warn control pack.

Bronze bush with grease nipple.

Smaller longer drum to increase pulling power but again at the expense of off load line speed.

Leaves you with this.

Motor with breather.

If you want more put 24v through the 12v motor but don't stall the winch

Oh and for getting out of the $hit this is what it can do just on the batteries.



Old school made better with a few minor mods.

Great Job Matt

Nice Vids and pics...

there is at least 3 of us running this setup.
this one has been bounced between trucks since i am too cheap to buy more than a couple winches.
BJ74
PZJ70 hard top
PZJ70 ragtop
and it was run on a number of 12V trucks before that.

the first time i had the "ooops" it was on BJ74. i am a poor boy and didn't have the money for a 24V winch and i had this old 12V under the bench so i hooked it up in such a way i just took the power feed and attached it to the positive post of the 12V battery when i needed it. the ground was to the ground cable of the system.
i was out wheeling with Daryl in his 42. he had ended up high centered on the diffs in a mud hole. we tried pulling him out with my tugg'm (another story for another day) and he wouldn't budge an inch. we tried his 24V winch but he wouldn't budge either and then i hooked up with my 12V to give it a try thinking his 24V was not working right. i got out and went to hook the winch up to the one battery but by mistake i hooked to the 24V battery. i hooked to his truck and went to winch in and DAMN not only did he come out of the hole, he came out FAST, like he was on a greased log. it was then that i realized i had hooked to 24V battery on my 12V winch. i figured since it was an old winch and a cheap one that i would leave it like that to see how it held up.

that one is still working on a buddy's truck, there is one on a 24V Mits jeep and one on this truck.
...
now that i think of it, this event was long before my move so that would be 5 or 7 years back now

DISCLAIMER:
i am not recommending that you all go out and do this, i am saying it works for me and it works VERY well. others might not have the same results.

What estimate would be for your max pull on 24v going through a 12v 8274? Something has to running super hot in there.
Anyone else out you know done this? -- sounds too good to be true.

Great story! - well if others are doing it, it can't just be a fluke for you. I have an old 12v 8274 I was going to change out to 24v, but I think now I will run 24v and see how she goes. If I cook the motor, she was going to get replaced it anyway.

This is a great forum. Thanks for the info.
