Build Ed’s Un-Did FJ40

[Rock40]

So clever!! What a time saver

Cute, until I realized that the PO had smoked the fitting in so hard it was ruined and a 4’ cheater bar just rounded off what was left. Welded a 3/8-16 nut to the top and finally got both out. Only caught fire while welding once, what a treat

Do you do your own blasting or do you outsource?

Both actually. Big stuff like frames go out, that was only $160 to get that done.

I’ve got a decent sized cabinet here and if it’ll fit inside, I’ll blast it. It’ll fit something like a rear FJ40 swing out door pretty easy. I’ve got a 125 CFM compressor to drive it if I’m really going nuts

I'm guessing a tow behind compressor for that much cmf? Have you ever looked into getting a pot to DIY it? I've been debating that for the amount of sheet metal I deal with

Yeah, it’s a tow behind Grimmerschmidt with the Ford 302 engine. Great when it actually runs

I’ve never looking into an actual pot, I’ve done larger stuff out in the driveway tho, using a 5 gallon bucket and the siphon nozzle from the blast cabinet. Works well

Any Landcruiser historians recognize this kit? Downey? AA?

It mated a Chevy SB to the stock Toyota 3 speed transmission using the factory rear bellhousing mounts. Definitely a production piece at some point, designed to run the small input retainer (SM420 4.687”) bellhousing.

The PO ran a bellhousing with the larger 5.125” retainer which defeated the indexing of the transmission to bellhousing

Attached is a pic from one of my old Downey catalogs. You make the call.

That’s awesome! So retro

Here we go, transfer case time. Thx for the kit @cruiseroutfit

All done for now. Still need to install the AA twin stick mode shaft on the 2WD/4WD shift housing. Left the e-brake guts out of it.

Toyota seal packing, best stuff out there for sealing a case

Looks super tidy!

A tutorial on how to wreck a 4 turn Saginaw box. Can’t not share it!!

thats a fairly easy fix actually. not too hard to change out the input shaft. just gotta not unscrew the center part that drops all the steering worm balls. still not hard to do even if that happens. I've built a bunch of those boxes, and changed things around to make them how I want them.

Ok, never tried taking one apart actually. Pulled another box from a ‘63 Bonneville in a yard here which should work as a core exchange with Redhead Steering. I think the cores are worth $250 or something

 

[John Smith]

I'm impressed to no end you have a yard nearby that has anything that old not crushed already.

 

[pb4ugo]

Saginaw boxes are not that difficult to rebuild. Just don't lose any of the balls. Here's my scout box.

Ha! I know. There’s just a few around here that have a row or two of old stuff. Hard to imagine they make much off them but

Nice, I’ll probably pull it apart just to see and learn something new

Little bit of leaf hanger repair…

Touch of silicone bronze on a few low spots and hit it with the DA. Small tack on the backside. Those M8 nuts should be quite a bit stronger than the threaded hanger

Notched the driver side spring hanger just a touch to clear the lower Saginaw box bolt sleeve.

Used old Toyota hot rivets and clamps to keep it aligned, then plug welded the old hot rivet holes

And normally the passenger side leaf hanger wouldn’t have been removed. Except the PO cut the hot rivets off leaving it only attached by the factory spot welds

 

[pb4ugo]

There are some videos out there. I think the Edelman kit was better.

 

[pb4ugo]

The 2 trickiest parts was dealing with the nylon seals and the steps to get them compress. There's several videos that show how to deal with them. There's also like 22 or 24 balls. There's two different sizes, usually black and silver and they need to alternate. Don't loose any of them.

Cracked open the GM NV4500 today. Ed thinks it maybe only had 20k original miles on it, insides sure seem to support that.

Figured the large balancer and 5th gear nut would be a pain, yep. Especially since I only have tools for Dodge NV4500’s

Called a local transmission shop to ask if we could borrow the special nut tool or actually bring the transmission in. Nope, apparently they just chisel the poor nut off. Not really my style but we don’t re-use it anyway.

Chisel wouldn’t budge it off the 300 some odd ft/lbs of torque. Ended up drilling the edge and cracking it with the chisel. MERCY

Chopped the end of the main shaft off according to AA’s instructions and sanded it smooth

Test fit the adapter extension housing, spud shaft and bearing. Good to go Yes, the dog is licking the bellhousing

Also found a date code on one of the front axle brake lines, nope. Certainly not using that, ha!!

 

[Rock40]

This is what you get when the PO assembles the front steering knuckles lacking any gaskets yet having a copious amount of anaerobic sealant on hand. Rock hard crap in absolutely every threaded boss

Got some media blasted fresh axles back too
