Just a little update on the progress. I started it up and moved it on it's own yesterday. Only drove it about a hundred feet as I was sitting on a stool and there are lots of loose pieces laying around inside. I just needed to swap garages and get the bus back in it's barn.
The engine noise was a lot less than anticipated with only a bare wood floor up front. There didn't seem to be any unwanted vibrations to contend with either.. I have some 2 lb carpet underlayment from Soundown that should help in the noise department but the dash needs a lot of help first. It seems to have disintegrated as I took it apart. I'd like to replace it with one of Frank Jenkin's units but the freight from Florida to NM is a real killer.
Another issue was with the new torsion bars holding the front up about two inches too high. I had a heck of a time with the unloader and almost couldn't put enough pressure on the pork chops to get the adjustment nut in place. I'm kind of scratching my head on this one as nothing was altered that should cause a problem like this. The pork chop mounting cross member can be modified but there must be another solution somewhere.
I ended up using an air cleaner off a Dodge truck with the Cummins diesel. It's a nice tidy package and fit the space I had. I mounted the two engine batteries lower , but close to the stock location with the air cleaner box above them. The two house batteries are now located on the opposite side behind the steering box. The inter cooler plumbing will have to wait until I can fab up a new intake.
Using the Azure vacuum pump for the brakes may not pan out and a hydro boost may still be necessary. I'll need some road time to evaluate the system for sure.
Integrating the two electric systems proved to be quite a challenge. I ended up cutting out the original fuse panel and splicing in the one from my donor truck along with an additional seven circuit panel. There are also an extra half dozen cube relays installed as well as circuit breakers. If this were a total gut out and replace job it probably would have been easier to start from scratch and replace everything. The Mac dash wiring is all complete although there is still a little work left on the charging system and house 12 volt wiring.
I've got to take another break from the job as the grand kids need a little help. With dad still deployed (9 months and counting) things come up that their mother needs help with. Just wish they lived a little closer than 800 miles.
Should be back at it within a month. Still lots to do and I haven't even started on the diesel generator installation.
