best gear setup for 62 CJ5

What makes you guys decide who to get what from? Novak/Herm/AA?

 

Went out to the yard to verify what all I have around.

This is an early pickup, judging by the speedo and vertically split rearend. I has a D18 and unknown trans. Can I use axleshafts and other parts of the D25 for the D27 in my '71?





Have a '49 and a '50 Chevy both with SM420s I believe, one with a PTO on it and a "brownie box" aux trans. Anyone every done anything with one of them in a Jeep? Seems it would make the drivetrain too long.



Also have a T-176 but sold the D300 form my '81 CJ-7. T-176 isn't much, 1st is only 3.52 I belive.

 

Chuck - Nice pics! Hey, I noticed you bolted everything up and then installed (engine, BH, tranny, x-fer) - was that the easiest way to go? What did you have bolted to your engine to hang it from - some sort of bracket?

Well, the pickup D25 is wider than the CJ, but maybe I can use some parts. Short side shaft maybe, stub shafts, locking hubs, maybe diff parts.

The steering box is stiff but not 1/4 turn sloppy like my '71, haha!

Here's some pics of the trans, got it to shift - it's a 3 speed, same pattern as my '71 CJ. R 1 2 3






What rearened is this? Valuable?





Maybe I should move all this semi-offtopic stuff...

 

The rear is a Timken, forget the model #. Pretty tough diff but can be hard to get parts for and gear ratio changes, well, good luck. I see a T-90 with a long input and GM adapter. Model 18 transfer case that if stock should have the 1 1/4" intermediate. Would be a small hole case.
The front and rear are wider than CJ so the housing and inner axle shafts could not be used from the front. The stubs, hubs, locking hubs, brakes, knuckles, diff gears, etc. can be used. Some of the later models of these used Bendix 11" brakes. Non selfadjusting but still Bendix 11". Might be able to add the self adjusting hardware.

 

Hey, look, I found a guru.

Thanks!

OK so from looking at pics a 465 needs grinding to clear the shifter tower and an SM420 doesn't? Neither seem to have drive shaft clearance issues, wonder which one would supply the most room for it. Not crazy about the super small stock shaft. Anyone know what the largest series yoke the D18 will accept is?

 

I would guess 1310 too. Warloch, you said you have a bigger one? Is the later model 30 stuff bigger than the ole 27? Don't have my Jeep here at the house to check and haven't looked too close, but they look small. Do you know the series of the u-joint or the dimensions? Dia of caps, width of cross with caps on or distance between tabs on the yoke that retain the caps. 1310 is about 1-1/16" dia and I can't remember the width, maybe 3-1/4"?

 

Based on granny's post in this thread, I'm guess the earlier u-joint is smaller than the D30 1310 joint.

I was under mine (stock) last night and didn't measure but it looks smaller than 1310. We do driveshafts here at the shop so I have a pretty good eye, though I don't ususally do much 1310 stuff.

 

So that's what all that noise was in the front... R) I don't like warn lock-o-matic hubs. Pain in the rear to take apart.





Not sure the truck axle is a 25 or 27 but it's 4.88 I believe. Probably a 25 based on the guesstimated year of the truck. Maybe I'll build a hybrid 25/27?

Hmmm...39 over 8 = 4.88, no?

 

F.Y.I.
The axle model number is on the outer casting.
It's embossed with about 3/4 " tall numbers.
A model 25 ring gear is 7.75 diameter, always with 8 bolt fastening.
Vs. the model 27 ring having a 7.25 diameter.

 

Make sure my SM465 doesn't look like that inside. :smash:
