Default PTO Winch with Slipper Clutch

Couple years ago I fabbed up a Delrin PTO winch with TLT gears. It was driven off of a seperate MRC trans, so I caught some flak for it.

Fast forward two years.

My Jeepster build has been on my bench for a year and is about 80% right now.
Rig weighs approx 9lbs in current state.



Applying about another 15+lbs of downforce (thumb on stinger) causes the slipper to kick in.




Top view of R2D2 linkage and three positions. Allows Drive/Drive+winch/Winch.

This is part of my current Jeepster build, but not sure how much it was seen there.

Heavy Metal KOH Jeepster Commando (C-101)

Pretty cool stuff...

I've often stared at the unused front outdrive on my 1/6th Jeep's Axial transmission (the back outdrive powers the transfer case) and thought about what it would take to turn it into a useable PTO.

You're disconnecting it with some sort of dig-style arrangement?

Thanks Mike!
I added the video that shows the three positions and linkage on the trans.
Just hope the gears hold up!

Very cool arrangement.
I've been pondering over a PTO winch design for a few years. ;)

Thanks for all the comments!!

It's a little chunky. Would like to have it going on a build where the front bumper was very broad very thick.

Could have gotten it smaller without the slipper. It's a Holmes hobbies 10 pole mini out runner driving it and the rig.
I wonder what the slipper will do when it gets wet.
Wanted it on there though so no one loses a finger.

Perhaps a ramped-key style slipper would be better?
Like they have in kids toys where a spring forces both sides together, but when it slips it makes a huge click or clunk noise as the teeth slide over each other.
You may be able to make it smaller in alloy or delrin.
