Adding OEM A/C to a M1097R2

[stucazz74]

Hello all. I am in the process of buying my second HMMWV. The first one proved too costly to restore . So now I have a donor M1097R1 to pull parts from. The one I am looking to purchase was not born with A/C, however the donor was. So I am looking to use the components from the donor to add A/C to the new one. How hard is this and what do I need be aware of to do it? Same engines on both, 6.5L Non-Turbo. Is this as simple as swapping the components from one to the other? Any advice would be greatly appreciated.

I might suggest you have a moderator move this thread over to the HMMWV thread versus this restoration thread. You would have probably had a bunch of replies by now. Just not getting seen by the right people here. @Guyfang

That is a very good suggestion. And done.

Also does the R1 have a 3 speed or a 4 speed?
Especially if it has a 3 speed have you ever considered using the R1 to restore the A2 truck? Again if the R1 has a three speed there is allot more to be desired in the A2 truck, Of course I have no idea what the condition of the A2 truck is in.
Please post some pics!!

As far as working on AC, you kind of need some specialized tools unless you have a AC shop willing to help you out with those bits.

• You either need a recovery machine, or someone to pull the R134 from the old system unless you vent it which is illegal.
• Then you can then transfer parts.
• Then you either need a set of gauges (inexpensive enough), vacuum pump (kind of expensive), and a leak detector method or someone to do that work for you.
• Then you, or your shop, can fill it up and enjoy!

You can check around and see if you can rent the tools or perhaps borrow them from some local part stores (some do).

How much vacuum does the pump need to pull?

How much vacuum does the pump need to pull?

500 microns or lower

If the R1 uses V belts and the A2 serpentine belt i see a problem with the compressor.
