Boxing the frame probably is more hassle than its worth for a regular on road rig. You would have to be careful welding it not to warp anything. As far as the speedo goes there are a couple places that will build a custom speedo adapter gear box to whatever specs you need so it will be accurate. Here is a link to a speedo error/tire size/gear ratio calculator:

I pulled the '94 12V donor truck into the shop last night.
I might just leave the P-pumped 12V attached to the built 47 RH 2wd unit and use it as a complete set up.
That will be completely different than my usual 5 speed manual 4x4 VE pumped 12V builds.

Please don't kick me off the 1st gen site if I choose to go that way...

Slush boxes are good, when you have that cup of Java in hand, and don't want to put it down to go from point a to point b.

You can pretend your shifting, just like I do.

I can drive my commercial truck with a 18 speed holding my travel mug in hand....shifting, steering and even turning corners....never have to put my cup down.

NJTman

Yeah, this might be true, but you cannot "pretend" you're shifting gears.

thrashingcows

True that...not pretending for me.... Although I have driven many "auto" commercial trucks, Allison, and computer controlled clutch and shifting (10/13/15/18spd units), and after almost 20 years of rowing gears I can say I do not mind them.

I remember riding with Dad in an early '60s Autocar...One arm thru the steering wheel on one shifter and the other arm on a second shifter. Rode with my Uncle Jim in his 1947 Brockway and it had the same setup.

Alec

That's why my father liked the aux stick to be on the near side of the main stick -- easier to make the close-ratio "snap" shift with the left hand through the wheel, and let the right hand follow a shift pattern & pause in neutral

. . . I thought everyone grew up in a truck with 230 hp hauling 120k on dirt roads in the mountains . . . It was quite a shock to learn about things like "automatic transmissions" . . .


Sorry about the Hi-Jack Oliver!

Blue Goose

no power steering...air? roll the windows down, maybe pop the windshield open if the truck is old enough...am radio if you could hear it over the engine...one air ride seat if you're lucky.

The donor powertrain was pulled from the '94 today.
I will be using the 160 HP P-pumped 12V and the 47 RH as a set.

The motor is sitting on the shop floor where I can do the KDP and case bolts, install a new OFV, swap out the turbo [it has an E-bay HX-35 turbo on it now], toss on a few gaskets, maybe an oil and water pump and install a fresh lift pump.
I will do this after cutting open the oil filter to check it out to do a final engine heath check.

The 47 RH will get the pan dropped, bands checked, new filter and refilled with fresh ATF.

The Ramcharger also got rolled closer to the shop lift, while my buddy Walter was over helping me at the shop, to get ready for pulling the tub to sort out the frame work. I will pull the fenders and core support next then head for lifting the tub off with the shop lift.

NJTman

Sounds like a productive day. Good thing with that huge storm heading your way. You'll be plowing....

oliver foster

This afternoon the front fenders, front core support and the body mount bolts came off.
I finally got to check out the front frame naked...I will be going with the welded in a diesel front frame half.
The front frame before the suspension arms has some issues I don't love.

The next step is remove the doors, steering shaft, e-brake cable, brake lines, fuel filler neck and the front seats, before pulling the tub.
This will give me access to the frame to cut it in half. It will also give me access to cut out and weld in a new drivers side floor pan piece.

Depending on the big snow storm, I might have some time to work on it tomorrow.

NJTman

Sounds like a fun project. How long before your welder dude to come by? Will he be able to get through?
How much fluff did ya get?

Tub today? Sounds like you're?on your way

We got about 9 inches of snow. Much less than the snowmageddon they where calling for. I didn't even plow out my own driveway. If it has not settled down a bit by Mon. I will plow it out for the UPS guy who is delivering some [MO]parts for the upcoming Wrench Week.

I didn't get the tub off yesterday, but I did get an hour or so before dinner to pull the wire harness and such off the powertrain.

I would like to see the frame ready for welding up in the next 10 days. Wrench Week starts on the 26th! I am hoping that after getting the rest of the 1st gens dialed in for the summer, we will have time left to get the powertrain dropped into the new frame. That would give me the specs. I need to get a rear driveshaft made up for it.
