Not my day. Not only does it appear I have the wrong compressor, but it look like the new Retro-Air tension pulley and Ray’s crank pick-up want to be in the same spot. I have a dim memory of somebody finding a work-around but can’t find it in a search.
If you figure one out come back and share. I have an EDIS and have been threatening for years to install an AC. I would think that the workaround would be to build a tensioner that fits in the original spot on the the left side.
I have EDIS on a 3.8 Mk2 engine and mounted the trigger wheel on the backside of the crank pulley. I took a stock trigger wheel (can look up size if needed) to a machinist and had him cut out a hole to slip onto the taper of the backside of the pulley. He also machined a flat into the pulley itself so it fits snugly. Got it positioned and welded it in place. Attached photo is before it was painted.
No, I figured I’d leave it like that to see if it would work…testing Erica’s theory
For those of you concerned…it was a trial fit for the pulley. Lock tab was replaced with a new one and properly installed after the pulley was painted.
One thing I like about this set-up is you still have access to the crank bolt. Ray’s set up covers the bolt head.
I wonder if it’s safe/smart to drill/cut a hole though the trigger wheel to expose the bolt?
That’s one of the reasons I did it that way. Ultimately I couldn’t find a direct bolt-on solution, so I was left to engineer what I thought was best. I also positioned the VR sensor on the inside of the fan belt loop so I can change a belt without taking off the sensor. The only issue I have (which I may fix before the engine goes back into the car…it’s currently on a test stand) is some minor interference between the generator and the VR sensor bracket when trying to put a belt on. Once the belt is on it’s not an issue, but when trying to create slack to install a belt it falls just a little short. I had to remove the fan and water pump pulley to slip it on. No big deal when doing this in the shop…but would be a bit of a struggle on the road.
Regarding your question --with a bolt-on trigger wheel, having a hole large enough to access the bolt shouldn’t be an issue. Most that I’ve seen do this.
OK, I think I’ve got it. The key was the AC compressor, it came with two pulleys, which is the type they provide in the kit now. So, I made a new bracket for their idler pulley and moved it up, adding a second belt to run the Alternator.
