Well it was in the upper 40's to low 60's last weekend and I go all excited to get this car back on the road but the nice weather seems to have broken and its back to normal 20-40's. Roads are still full of garbage so not driving this car yet. Its still march though, no harm no foul.
I did pick up a brand new sanden 508 style AC compressor of FB marketplace for $75 that someone had bought for a ford 302 vintage air kit and never installed. Original plan was to try and use the factory bracket and pump in some form but the more I looked I didn't see an easy method to make it work. Eaiser to go to a known pump with published dimensions.
I did some research and this bracket is basically what I want to do except it needs to sit farther forward (on the front 6 rib drive) and have an additional idler pulley potentially. I like it, its simple, clean, and something I can fab easy. Plus, I get to try out the waterjet on campus. In person classes are cancelled until April 1st with this whole coronacircus fiasco so all the undergrads aren't in the shop so I have sorta free reign as a grad student. Ye-haw
Since I made my own belt routing to clear the blower, I think this is what the AC setup will look like. Thanks powerpoint and snipping tool (my favorite engineering tools haha). Only thing unique I have to come up with is the blue tensioner pulley and the yellow arrow for a tensioning force. The distance between the tension side of the AC pump and the slack side of the water pump seems a bit long also so I might end up throwing another idler pulley in there. If I do, I will end up putting a bracket attached to something and double up that bracket to mount a traditional idler to. I think i saw a dodge 05ish 4.7 used a 6 rib tensioner that should work for this setup so I just gotta start drawing parts and doing some fab work and see where it ends up.
I might be able to be sneaky and use the 3rd mount tab on the pump itself in between the top and bottom mounts of the mounts that bolt to the block to fasten the tensioner to. I think I will have to go with a normal coil spring instead of a clock style spring usually in a tensioner and fab something up but i think it will work out.
