I want the land cruiser to have air conditioning. If you do a search for R2.8 and air conditioning you will find that there is a compressor available. What isn't abundantly clear is that it requires some modification to fit and isn't really in the greatest place. Here is a picture of the front of the R2.8.
The top accessory is the alternator. Below that is the power steering pump. Last there is an empty spot. Looks prime for an AC compressor. It's a bit misleading because the AC compressor will be very close to the frame rails and is fairly deep so it might interfere with some motor mounts (you'll see how this is avoided later). I wasn't too keen on putting the angle grinder to a brand new compressor so I kept doing research. I discovered some parts that reconfigure the front of the R2.8. There is a new bracket. They call them "mega brackets". It is surprisingly inexpensive. Here is a list of parts.
Bracket = PN 5286677
Tensioner = PN 5262500
Compressor = PN 5295582
Belt = PN 5254354
M10x1.5mm x 35mm long Quantity 2
M10x1.5mm x 100mm long Quantity 2
With the new bracket there is a suggested change to the tensioner, and a longer belt is needed. The tensioners look identical, but are different numbers. I assume it's got a different pressure spring. It's only 20 bucks so not worth skipping. I ordered all of the above from my local cummins depot and the total bill was a hair over $300. Not bad really considering $200 of that is the compressor. Today I started swapping everything over.
Comparing the new bracket (in hand) and the old.
New bracket "installed". I realized I needed some different hardware at this point.
The new bracket is a bit different than the original. The mounting pads for the fasteners are all the same height on the new bracket. The old bracket was thicker in places. This is why there are a few 45mm long bolts listed above. The below picture is the longer bolts that came out of the old bracket touching the threads on the block If you try to insert them in the new bracket. They are considerably too long.
I also had to close up a small gap between this press-in insert on the bracket and the back of the power steering pump. There is a fastener that goes in from the back there along with three on the front. I bet just tightening down the fastener would work, but I didn't want to break off an aluminum tab or something. A solid tap got it to close up.
Similarly I had to push out this press-in insert that was in the alternator just a little for it to slip over the new bracket. I threaded the long bolt from the alternator through to it and then hit the head of the bolt just a few times to press it out a little. It didn't take much at all.
The longer bolts above, with the nuts are for mounting the compressor. The compressor doesn't come with hardware. Here it is all set.
Here's a few pictures between the accessories and the turbo. These all show the new setup. You can imagine how having the ac compressor on the bottom would be a bit of an issue.
The only real downside to this setup is the inlet to the turbo will have to turn out pretty quickly. Still enough room considering the turbo is so small it won't be quite as gradual as it could be done with the power steering pump in front of it.
Just have to kick out turbo outlet a little. It's on a v-band so it will be easy. Keeping it straight like this would make tubing easier though. I'll figure that out when it's in the truck.
