Builds "Chunk+12ht" version 2.0 (5 Viewers)

So, sorry if I missed it but what's in those cable-lock diffs? 3.73's or 4.11's?

They are 4.11's. I kinda wish they were 3.73 for the diesel on the highway but for low gear wheeling it will be nice. I think it will be fine for 70 mph, just not sure about faster. At least the 5 speed will drop it down a bit in 5th gear.

You’re going to want some 35” rubber or overdrive T-case gears with 4.11’s even with the H55f. Offroad it will be nice though.

I have done some rpm calculations and 2500 rpm (on a 33" tire) should be 70ish mph, and 2700 rpm 76ish mph. The 12h-t can roll that rpm fine but lower would be nice. I may go with a 17" Wheel Vintiques wheel with a factory cap and run KO2 34" tires but that is a lot more expense over the 33x10.50-15 and steel wheels I already have. @bdyer12 has 34's on his truck and it seems pretty nice on the highway like that (1hd ft). I drove his 60 when my 12h-t was in it but never up at highway rpm. I have 33's and steelies on my fj55 that are brand new so I will probably run those initially and see how it goes.

Midnight madness time. I decided I wasn't going home til the housings were coated and headed home with me. I tried getting some hours in during the day but had other stuff to get done. Got back at the powder shop at 4 and should be out of here just after midnight. Some grinding, some welding, some blasting, prep, and powder coating. Not crazy about the spring plates but otherwise it all looks pretty good. Ready to sleep!

 

[dogfishlake]

Forgot to get the rivets out of the rear body mount brackets before powder coating to fit my 4plus bumper,
I got all the others at least. Came out clean enough that I can do a nice touch up job on it.

 

[dogfishlake]

Last night I was able to get some suspension install started. The housings are just sitting on the springs but it made me feel better at least making it LOOK like a near rolling chassis

Getting more axle pieces ready for blast/powder coat yet this weekend.
Funny thing, I've assumed from day one my cable lockers were 4.11's and didn't check. I would really rather have 3.73's but not spending the time/money right now to switch. Spent 24 seconds checking tonight and lo and behold, I have 3.73 gears!

The diffs have been apart previously as evidenced by the copious amounts of rtv. Not sure if they were added later or were original. Pretty cool though. Every dog gets a bone now and then.

That gear ratio puts me just under 2500 rpm at 75mph with the H55 and a 33" bfg which really is probably 32.5" tall. We shall see

Can you check the gear mesh/contact pattern with them in there?
May be worth seeing if they (R&P) were done well if they were done...

Not sure I want to know, no time to redo! Haha, seriously that is a good idea. They look good just checking what I can see in the wear pattern on there but some paste wouldn't hurt. For all I know they may be stock with 3.73 gears on some of these, perhaps an automatic truck? I think I saw a comment from @SteveJackson about that somewhere. Maybe I'm dreaming.

 

[Trapper50cal]

My knowledge is very limited and is NA based...

All I know is that the North American 60's had 3.73's and the 62s had 4.11's so people
were really coveting 62 front diffs to get hardly used 4.11's.

I say if you got the ratios you wanted and the wear looks good, run what yah brung

hj61's had both 3.73 and 4.11 I'm not sure who started the myth they were all 4.11. The set of hj61 axles I built up for my 60 are 3.73 and they were from a European truck. The set I built for tuckers 40 (only used the thirds) were from a japan spec rig and 4.11

I like the 3.73 for highway cruising with my current tires (31''s). I'm actually thinking when i move up to 33s I may prefer the 4.11s but a little too late at this point and wont really know until I put some miles on it.

I'd be willing to bet it was either an option or more likely the auto got one ratio and the 5 speed got the other (not sure which got which). It sure was a nice surprise though. As long as it isn't too high geared on the trail. This truck wont see rock crawling anyway, my 80 can do that pretty well and I think the 73 is going that direction too (not even here yet). Plans for this 60 are to have it be a nice ride down the highway to destinations in northern Michigan ranging from 2 hours away to 6 hours away. Once where I am going, the places I like have miles of 2 track that are the snowmobile trails in winter. Water puddles, big whooped out areas, sand tracks, etc. Not much rock really, more in the western Upper Peninsula that is fun. WIth my kid headed to Marquette for school, I will spend more time up around there for sure. Maybe a set of tracks on it for winter? I even know where a set is for a Toyota 6 lug. Dream stuff for later.

I got a bit nervous when I discovered the rear locker wouldn't engage. Upon teardown I found the head of the bolt the holds the shift fork broken off. The broken piece stayed up in the actuator thankfully. Quick trip up the street to see a buddy at the tool and die shop he works for (and me too, doing powder coating) to get the broken part out. He tig welded a stud on the broken part and popped it out for me. The shouldered bolt that goes in there is amazingly still available from Toyota so two new bolts are on the way for both front and rear lockers.

I have a couple of those bolts for spares. Same as the 80 elocker ones.
Just came home to a big package in my carport. What could this be?

I figured I would save the extra I have for the spares box. Brand new retail is $2.99 so I figured it was worth replacing both bolts. Too bad all the other parts are obsolete. New cables would be nice. Mine work fine, but they are ugly. They will clean up ok.

Something shiny in that package there, methinks.

@roma042987 , I think I see a spot of oil stain on your floor from pulling the diff cover on my stupid truck. That was huge helping me check that out. And letting me stay. Cheers buddy.

Wasn't first oil stain and definitely won't be the last. Shiny it is! Awesome packaging by the way Pat.

$30 and a weeks' wait, and my axle and diff bolts are plated and beautiful.
