ARB PTO Winch Bumper (HJ61)

There has been a few threads about fitting the factory PTO winch into an ARB bullbar but nothing definitive about how it is done just that it could be. To further complicate things, I did not realize that there were two different versions of the 60 series bar and that I had the "new style" which would change things considerably.
So anyway, this thread is my contribution to the Mud knowledge base.

The first thing that I did not realize until I began this project is that the winch is not in the centre of the vehicle and is, in fact, offset to the left side. This will be discussed later as I had to offset the hole for the fairlead. Next I elected to mount the bumper at the middle height of the three sets of holes available. I found that this position looked the best and actually covered the front indicators rather than leaving them partially exposed. There is another thread that shows what the various options are with the new style bumper.

So basically there is two main operations in getting the bumper to fit:

1) Cutting the bottom edge to allow the winch gearbox and drum to clear; and
2) Fabricating a new plate for the front "feet" of the winch to bolt to.

The first part was easy. I mounted the horns the frame rails and cut the large piece of angle iron that supports the winch so that it would fit between the horns. It is important to trim the same amount from each end of the angle so that the holes for the winch remain in the same position relative to the front of the truck keeping your PTO driveshaft aligned.

Next I hung the bumper on and marked where the gear box and drum were fouling the bottom rail. I also marked where the front feet of the winch were in relation to the existing mounting plate.

As you can see from the previous picture, the feet are much wider than the plate that was designed for electric winches. I started by removing this winch plate but in the end I could have done a lot less cutting.I did not need to cut out the thickening plate that ran along the bottom of the bumper rather I should have just cut out the mounting bracket itself.

I then attempted to fabricate a mounting plate of the original mounting plate from the front of the PTO winch as I could be assured that the bolt holes would line up. This too was a mis-step as I eventually bought some plate and made a complete new one which looked and worked much better.

Next I had to widen the opening to accommodate the location of the drum and fairlead as well as the mounting bolts for the feet. I drilled the corners with a 19mm (3/4") bit to give a similar radius as the other side and then cut the opening with a zip wheel.

A better mounting plate was fabricated and fitted. Side plates similar to those in the original mounting plate were added. The difficult part in this whole exercise is getting the bolts for the front feet in the right location. Be sure all your mounting bolts on the bumper are tight when you do your alignment as even a small change will leave those front bolts off which could be a nightmare.

Next I just welded everything up and splashed some paint on it. The powder coat was scorched in several areas but I found a Krylon satin black with a light clear coat matches up pretty good. You will note that the fairlead is too thin and at an angle there is a chance that the line could abrade on the front of the bumper. My plan is to either set the fairlead out with a spacer or Viking makes a nice thick fairlead that may fit perfectly. (1.5" thick, double my current fairlead)

Next steps include building a small skidplate for the Winch gearbox and mounting the locking tab for the freewheel lever.

(PS: no comments about the curtains; they were there when I bought the garage and my bumper has taken priority over decorating :D)

Wow, really good fab work, impressive. I just did the same thing mounting a Warn 9500 compressor winch to my new 4+plus bumper. It's great to see this done and recorded, very cool!
 
Unless there was an un-modified ARB next to yours I would never notice. Nice fab work!
 
I hate to bring this up but I make the 4-PLus front in versions that accommodate
both the compressor winch and the 8274. I also make a version for the 10,000-
15,000 class of Warns

Wow. That's really awesome. Thanks Jason , you helped me cut through a ton of hours. I do believe I now have what I need for this to work . Cheers all. I'll report back with my own experience and a pick or two with new addition. She's going in for some body work soon and new paint.
cheers all.

Do you end up doing something similar? I'm about to embark on the same path.
