Re: '46 Chevy Shorty

Hey Trunt --- Can't say as I've accomplished much but have begun removing the front sheet metal in preparation for the engine install. Grinding off more nuts & bolts than will otherwise cooperate is a pain. Sixty-six years of not moving makes for some mean fastener removal! And I am more convinced than ever that things were indeed "made better" in the olden days. Had one thoroughly frozen, slot-head sheet metal screw that wouldn't budge so I started out trying to whack it loose with an impact driver after soaking it in penetrant. Broke two Craftsman bits without budging it. Then I tried the drill and only succeeded in busting two Rigid bits without even even scratching it. The last resort was the angle grinder with a thin cutting disc and even it had a tough time cutting that sucker. Plus I wound up having to weld in a piece of steel to replace the spot-welded screw fastener that I wrecked in the process. All in all, probably an hour-and-a-half on one REALLY hard screw. The danged thing must've been Rockwell 28,000 on the hardness scale.

Anyhow, here is where I am now. Just hope I can remember how it all goes back together.

Man that is some nice looking sheet metal--makes me jealous.I agree that the old stuff was better quality.

Re: '46 Chevy Shorty

Yeah Trunt --- most of the "Chevy Metal" was in outstanding shape. Just a couple of small rust holes down low on the cowl behind each front fender. No dings or evidence of any body work on the whole front end so far.

Finally finished up hanging the black/gray tank today. Drilled, rust-proofed, painted, added rubber pads, and mounted the four big straps that support it on bottom. Now to get back on the fuel tank. Also visited my engine today. Dang it looks purddy! They threw on a coat of Cummins tan that makes it look almost brand new. Went there just to pick up my intercooler so I can begin the head scratchin' on how/where to mount it. It's real big, but I think if I cut & rotate the inlet & outlet I may be able to make it work. Sure hope so, as good custom built units don't come cheap. I am thinking I can route the big air tubes out through the inner fender then back into the grill. It will be close but hopefully doable. No problem with wheel clearance as the will be tucked high and close to the inner surface.

The trip also paid off in another way. Chatted one of the techs about various options and he wound up giving me a key remote oil filter component. Should really help as that engine is going to be a really tight fit. Also need to figure a similar system for some power brakes. I seriously doubt there will be room on the firewall to hang anything I've seen so far. Has anyone else here had to deal with/rig something similar? I am definitely open to suggestions.

Then there's the whole power steering thing...

Re: '46 Chevy Shorty

Hey Tango, I did a '56 chevy PU a few years ago and wanted a completely shaved cowl--so no brake stuff. I ended up using an aftermarket combo MC and vaccuum booster designed to go under the floor board. On the '56 the clutch and brake shared the same pivot point so I just cut off the clutch pedal below the pivot and used the stock brake pedal. I am assuming that the original MC on your bus was under the floor, correct? The kit included a proportioning valve set up for front disc brakes and drum rear though I'm sure that could be changed or eliminated as needed. As I remember the instructions were written in Chinese, translated by an Indian and copied on a mimeograph machine--they SUCKED. Anyway, the system works fine but throw away the instructions. Who made the kit you ask? I CRS but if you want I'll dig through my reciepts and let you know.

As far as the PS goes it isn't all that hard to figure out. Your Cummins might have a built in pump on an auxilarry drive like my Isuzu and if push came to shove you could adapt the old school drag link operated slave cyl -on- the- tie rod mechanism that Chevy, Ford and Studebaker used in the '50's and '60's ( Chevy actually used a pump run off a shaft sticking out of the back of the generator). That would eliminate the need to change out the steering gear (You'd be chasing the steering wheel a bit but man would it have power).

Of course I'd recommend changing the whole thing, column, gear and pump but that's only an effort to make more work for you

Wish my tanks were in (read green). Jack

Sounds like the first Lotus factory repair manual I bought. Loose leaf binder printed with a really BAD mimeo.

Re: '46 Chevy Shorty

Howdy Trunt --- This rig has the original single pot MC hung on the firewall with the pedals pushing from the other side (hydraulic clutch too). I'm going to need to locate a power brake elsewhere but will still need reasonable access to the MC for refills/service. The clutch goes away when the auto goes in. It does have a factory Hyrdoboost, but that will like give way to something newer...just not sure where to put it all. Under the floorboard appears to be the only option. Maybe with a small hatch to access the MC. And Roger the proportioning valve. Can't see dialing in the jury rigged system any other way. Right now I am looking for a complete package that has reasonably similar fluid moving capabilities...i.e, piston size & volume. The Cummins engine/tranny package came from a P30 Step Van and included a hydraulic pump & steering unit (no vacuum anywhere), but I will need to go through/rebuild it before I know what I have. Might work, might not. Would love to go with a Ross power steering system from the wheel down if it could be made to fit. The original gearbox is on the inside of the frame which makes for a tight squeeze. Once again, I wont know until I start stuffing that motor in and see what (if any) space is left.

Hmmmmm...maybe I should be looking into "fly-by-wire" systems. Any Drone mechanics out there?

Re: '46 Chevy Shorty

Might have been easier to get a newer frame and mount the 46 body on it......
just thinking out loud here....

Re: '46 Chevy Shorty

Hey GrayEagle --- I was tempted, but the very narrow "art deco" front end requires more mods than I was willing to deal with to keep the big,
old style wheels & tires that I think look right on these rigs (the hot rod look is not my thing). But I do envy those with the new running gear, rear ends & brakes...or...the talent to cut & fit a frame as necessary...like Trunt. I followed a P30 chassis makeover that made my head hurt just trying to keep up with all the frame and axle chopping. In the long run, it may be easier, just beyond my limited savvy.
