split case 4:1 gear sets!!!!!

[Cruiserdrew]

The larger idler started in 4/86.

The output gears changed with the introduction of the FJ62. I don't think they are interchangable. The late Fj60 output gears were supported by brass bushings, the FJ62's by needle bearings.

But as has been said, you could swap in a late 60 output shaft into a 62 case and use thes new gears.

 

[orangefj45]

If they had the same size idler shaft they should be. Though I think the larger idler (38mm) started in 1985/6 after the FJ60 and FJ40.

not quite.....

the "long" h42 started in 85, the 38mm idler upgrade was in april 86. the low and high output gears from a 60 and 62 do not interchange, neither does the idler. like any mentioned, the difference is the bushing vs bearing supported gears. the bushings are a lot thinner than the bearings.

personally I only see running this set if an additional range box is also used especially behind a stock landcruiser motor. If someone was just going to run rocks all the time it would probably be fine but I think it limits your options too much.

Hmmm...From a cost/benefit perspective, this gear set is pretty amazing. With essentially no mods, you go from inadequate off road, to almost great off road. Obviously a range box is nice, but an H55f/4.0 gear set/4.88's would put you close to the 100:1 sweet spot for real wheeling.

I am especially stoked about these gears behind my H55. If it's limiting, I don't see it. Just the opposite.

If you are willing to give up some highway friendliness, an SM465 coupled to a split case with these gears would be awesome for fairly small $$.

If these gears are widely available, I see them as a significant option that was not available before. In fact, they may see their greatest use in FJ40's behind an H42/H41, and completely eliminate the Orion.

Especially for people that want to run a 2f-h55-split case in their 40 without significant wheelbase changes. You can have awesome gearing without an 8 inch driveshaft.

I have two Cruisers and my FJ40 is getting an H41-Orion in it.

The H55 overdrive would compensate a lot for the extra low gears on mild trails.

Isn't the H55 about the same length as an H41/42 with a toy box?

H55/Split case is shorter than H42/toybox/orion. So yes, a tidy package in an FJ40. I'd still run an H41 instead and keep the drivetrain short, and the rear shaft as long as possible.

The over drive gear in a 40 would not see much work.

 

[GLTHFJ60]

I've read that the 5th gearset is the weakest out of all of them, so it is not advisable to run in 5th at all while in low range.

Isn't the H55 about the same length as an H41/42 with a toy box?

No, the H41/42 in the short configuration is shorter than the H55, but the H41/42 in the long configuration is the same length as the H55. I would expect the H41/42 short version with Toybox to be a bit longer than the H55 by itself but I don't know for sure. How long is the gear reduction portion of the mini transfer case?

For going slow and crawling... I agree. However, I've been in lots of situations where some wheel speed is more important that "crawling" up something. Not too mention crawling in 4 to 1 on a long section of trail where "HI" isnt low enough to get you up the hill only leaves you the 4 to 1 to move... that would get really old moving that slow over a long section. Honestly, I think running a auto makes more sense with the gear set if doubler is not used but I'm an auto believer. I hate sticks for trail rigs (probably my lack of skill ).

To each their own. I'm not condemning anyone nor saying that the gears are a bad idea, just that the gear set leaves a void in some "on trail" situations without an additional range box.

So I get a 62 series case (and 62 series A440 since the 62 case wont bolt up to my A440), a 60 series split case output shaft, and these gears.....and it will all fit together nicely under my 80?

Theoretically, yes.

I run a 4:1 Orion in my 40 and I absolutely love it. I can CRAWL, and if i need wheel speed I can always run 2nd or 3rd gear low range and get all the wheel speed I need.

I also run no e-brake on my Orion because I have a late model 40 series FF in my truck w/ the parking brake at the wheels. I also have a rear line lock which I used before the FF.

I see an 80 axled, small block, 4 or 5 speed, Split Case Buggy in my future.

 

[wngrog]

I see no limitation to 4:1 if you are running 33's or bigger tires.

What this does is make a 60 something that you can build as a moderate wheeler without breaking the bank.

60's are almost free these days......

I don' t see why you'd spend the $$ for a 5 speed for a buggy.

Sad but true...

They don't get expensive until after you buy them.

But why, besides weight, would you want to eliminate the Orion? Front output?

Also, as an aside, can you swap the bushing output into a A440 so these gears can be utilized behind the auto?

i could'nt dis-agree more. you'd rather wheel with an auto with a single low geared t-case than with a standard and wheel speed is one of your concerns? unless you're running a full manual valve body you have to wait for the auto to shift it's way thru the gears. with the standard trans you can take off in whatever gear you desire.
and i don't subscribe to your theory of high being too high and low being too low either. you can't tell me that 5th in low is too low and for the same trail 1st in high is too high. even 4th gear in low range is higher than 1st in high range.
i like both sticks and automatics and they both have their place.

the split case shafts are way stronger than the early case counterparts. another item people negelct to see is that the split case utilizes a greater distance between the transmission main shaft and the outputs. so there's more offset for the split case which means no or less driveline clearance issues for guys running transmissions other than the oem standard units.
as for the bushing output, yes, you can install the main shaft from a standard trans version split case into the auto split case. no big deal.
