Ok, four weeks since I posted and the winch is installed!
The Jeep winch plate arrived from Morris 4x4 in the USA. Here is a picture of it with the crash bar:
I had the crash bar modified with mounts for the plate in a similar way that forum member Fawlty did for his winch. Here it is from the top:
And here it is from underneath:
This is a close up of one of the top mounts:
And this is a close up of the underside:
I gave it a zinc undercoat:
And then painted it black:
I dismantled the front grill and bumper, took off the existing crash bar and fitted the fabricated winch bar:
I had to cut out the rear of the winch plate a little on each side to take the turbo intercooler (?) pipes and I cut the front support for the bonnet locking mechanism so that it now rests on a piece of rubber on the top of the winch housing. I also had to cut the bottom off the plastic air deflectors so that they now sit on the winch plate. This is the deflector on the off side of the car ... the gaffa tape covers repairs I had made to the deflector which had shattered in a previous hit the bumper had sustained in a car park!
Here is the Warn winch during installation:
Here it is with the front plastic bumper support back in place:
And here is the finished installation:
There was plenty of room to install the winch, and the bulk of it sits behind the numberplate where there is no air intake. The top of the winch sits below the upper grill, so it does not interfere with air flow there, and the plastic angled deflectors, mentioned earlier, pick up air each side of the fairlead, directing air to the radiators behind the winch. I've had no overheating problems so far.
I chose the Warn Zeon Platinum 10s Winch (10,000lb/4,545 kg pull) as it has a wireless remote control and doesn't need manual clutch release. The wireless activation button on the back of the winch has to be left on for wireless operation and the switch has a flashing green led light, so there is a small current drain ... I don't think it will be a problem for the house battery and if I don't plan to use the winch for months, I can pop out the VW badge and reach in to switch the wireless off.
The Warn fairlead is huge, but it just fits in the lower grill!
