Overdrive did you install the idler pulley? If so, was it a grooved pulley or a flat, serpentine style?

It's a single groove pulley.

 

[InMemoryofRex]

Is that compressor for the C7 or the 3116 engine?

 

[tybaslee]

how many pounds of Freon is everyone using on the setup?

Does anyone know where I can get the pulley that goes on the engine crank for the AC kit

M1078 or M1078A1?

 

[Rage]

I have a m1078

I have a m1078

Can't help you there. I've got a couple of pulleys for the C7 (which doesn't help me either). I haven't seen a loose one for the 3116. I'm going to see if I can't modify the one I have to work but it's not a direct bolt in.

 

[Lmtv772]

So you have a pulley that will work on A1?

Yes. Scottmandu has them.



From what I could tell in the schematic for the 3116 the pulley is on something that sticks out from the engine like a block or "pier" with the pulley on the very end. This one looks like it just bolts on to the head or something else but more direct to the engine. Since I don't have the drawings for the A1 AC system can't speak directly as to how it mounts. And as I don't have a NSN or P/N with it I cannot verify what exactly this fits.

The picture of the parachute tiedown cover, what is that for? My truck is missing one of them & I need to replace it! A/C system, that is a ways off for me with no window & air system problems!

It came in with the pulley pics and I couldn't delete it.

I have an M998 ac kit sitting waiting to go on once I get brackets for my 3116 engine.

 

[mkcoen]

Yes. Scottmandu has them.

Okay after reviewing the schematic in Overdrive's thread (http://www.steelsoldiers.com/showth...Compressor-Mounting-Brackets-Install-Write-Up) it looks like this is the correct pulley for the 3116 after all. I couldn't get a very large version of the pic but now that I have one in hand and look at it again it does appear to be the one I, and so many others, need. Sorry for the confusion, jumping to conclusions, etc, etc. But the good news is they're out there.

What's the damage on these pulleys
