Winch Mounting

[Barrman]

We are finally done picking the engine up and down in Pistolnut's truck. So, now we can mount the winch. We have all the pieces along with the fasteners. Sitting in a pile in the bed. I have the one exploded view I can find in the manuals as a map. But, I can't remember what order we took it apart 2 years ago and I have all different students from them as well.

Anybody out there care to recommend an order to putting the parts on the truck that works? Thanks.

Thanks Jon. I guess I was looking for pictures too much instead of reading.

I hope it does the trick...I have never worked on a winch on these trucks...wish, but never been there...so I cant say how good the list above is...

[gimpyrobb]

Tim, the bar and side brackets that go against the frame are NO FUN to get lined up. Please let someone work on that that has patience.

[Barrman]

I remember the student that took it apart did not have patience. The one assigned to it now has plenty. I am having him piece everything together in the bed with the proper fasteners and all. We have already figured out the case halves are too close together after the winch rebuild a year or so ago. Which is a good thing to figure out now instead of when the winch is hanging from a hook.

Might be a good idea to post what works and any problems...since this seems to be something of a blind spot...
