Update.
Have been pretty busy with work, but I did manage to get some work done on the truck this past week.
First off, the doubler is slowly progressing. I used my uncles mill to get the filler pieces I welded in the sit flush with the case so it will contact the plate evenly.
I also got the shaft made, I turned the tranny output shaft down and pressed it into the tcase shaft. I made it about .005” interference fit, so the press fit held it straight when I welded it.
I also threw together a quick and dirty OBA setup. I decided to use two air compressors from Lincoln Continentals with air ride. They are only like 20 bucks at the junk yard and are simple 12 volt oil less compressors with Teflon rings on the pistons so they last damn near forever. I was going to use the compressor from a Town car, but I found the Continentals with 4 wheel air ride have a compressor with a longer stroke. The heads and pistons are still the same as the Town Car though.
I had to modify the compressor a bit to make it work. I removed the twist lock filter-drier thing with push lock 3/16 fittings, since it was a pain to work with. I pulled the head apart and removed the valves so I could make sure I kept all the debris out. I cut the part off of the head where the filter locked in, then I drilled and tapped it to 1/8 NPT, this way I could just is a threaded hose barb. The Lincoln also had a solenoid built in to the head to release pressure off of the bags, but I am using a external head relief, so I wanted to remove it. In order to remove it I had to drill out the hole in the head a little larger, then I tapped it to ¼-20 and used a bolt with RTV to seal it up. Under the plate where the solenoid was is also the intake hole, so I made a filter out of a scotch brite pad and stuffed it behind the plate.
Here is a comparison of the head before and after.
I used 3” muffler clamps to mount the compressors to the side of the box. I used an old air compressor cycle switch to control two 30 amp relays to control the compressors. The switch turns them on at 90 psi, and off at 120 psi. It also has a valve that releases pressure between the check valve and the compressors once the system reaches 120 psi.
I was able to use the check valve from the same compressor I pulled the switch from. It has the ¼” head relief fitting already on it.
I pulled a little two relay box from a Ranger at the JY to hold the relays, and I ran an 8 gauge with from the rear battery to a 40A breaker that supplies power to the relays. I found a rubber grommet at work that fits perfect in a 2” hole and allowed me to poke holes just big enough to shove the hoses through and keep the box sealed up from underneath.
I used a vent from Lowes that fits in a 2” hole to make an intake hole in the box. I also cut a scotch brite to fit behind the vent to make a little filter. I put toggle switch on the box so I can turn off the compressors as well.
I also had my dad make me some trim pieces for the edge of the carpet. Since everyone with a 93+ Ranger knows how fragile the stupid plastic ones are. They are stainless steel. ¾” x ¾” x ¾” Z-bar. I held them down with Stainless screws as well.
And lastly I finally got around to fixing the less than desirable shackle angle I have had since put the 5.5” Chevy lift springs on.
Here is how they looked before.
Getting the weight off of the springs took a little while.lol
With the slightest bit of a load the shackles went completely horizontal and the Chevy lowering shackles I used have beefier sleeve for the bushings and they rubbed the hanger whick made my truck squeek every time I turned or hit a small bump.
So I made new hangers that move the mounting point back about 2” and down about an inch. I used ¼” plate and some 1.5” x 1.5” x ¼” wall angle.
Now the shackles are 90* to the spring, and they don’t squeak, and my truck doesn’t lean back at all. My tuck used to sit almost perfectly level, but if I was accelerating or parked with my wheels turns or on a hill the truck leaned back, which I think looks atrocious.
I also turned the shackle around while I had them off. I remember getting shit about how they were mounted when I first put them on.lol
