Official Crawlbox BS thread!

I believe they used to be, but they both tell me that they are cut to toyota factory spec for the splines
If there's a ton of slop then I'll try and get my hands on a MC 26-23 coupler maybe.
I'll let you guys know how the fitment is when I get the adapter in and can test it out.

 

The spline cut is the same and the fitment was tight on mine. But let the masses believe what they will. lol

 

Are you running 2.28 or 4.7?

 

2.28

 

Those are purdy. Whats with the atlas thing? I can still run those right? I dont have an atlas? I know, im a noob. Lol

 

Yep, just a knob, you would need to figure out the thread on them and fab up a lever. I have a set of the plastic ones that came with my case you can have if you want.

Looks like they are 1/2-13 threads

 

Thanks bro. Mine came with blank ones (rad designs). I think those billet ones will fit

 

The spline cut is different between MC 4.7 and TG 4.7. If you're comparing factory 23s 2.28 input to TG 23s 2.28 input than maybe since your running 2.28 instead of the 4.7

 

I'm comparing Marlin's 23 Spline Total Input, which is in my case, to TG's coupler. So please explain how the cut of the 4.7 could be any different then the cut of the 2.28 for the splines. It's not like they have a matching coupler for the 2.28 and the 4.7 23 spline. It's the same coupler on the input side. The only difference is the 26 or 23 spline on the trans output.

 

Mc 2.28 cut is the same for their 4.7. I'm comparing mc 4.7 input to tg 4.7 input. @Spoonman had a video using tg coupler with mc 4.7, lots of play. Spoonman post on page 64 post 1271 will explain itself.

Only if I could find the picture i took when a local business had mc 4.7 input next to tg 4.7 and their 23/23 coupler for comparison. Looking through the coupler, the spline are different. The tg coupler will fit on mc 4.7 but it had so much play, you can move it freely by hand. The mc coupler on the other hand will slide into tg 4.7 input, but with some force. Once its in, is a tight fitment, not like the tg coupler.

So yes, I would say the cut is different between the two.

 

Interesting. When I bench tested my duals I placed the TG coupler over the Marlin 2.28 TSI. It fit perfectly. I had to give it a few tiny love taps with a mallet to get it on. It's very tight with zero slop. I believe @betterbuckleup is going with the Marlin 4.7 TSI and TG adapters. Maybe he'll be able to verify the fitment.

As for the Marlin 2.28 and TG coupler it's fits like I said upthread. I have 3 years of running it that way. I've always wondered why you guys think it doesn't work but never gave enough of a shit to post up about it. @betterbuckleup sent me a PM asking me about it. Then he called Eric at Yotamasters to verify it. Eric said he sets them up with Marlin TSI and TG coullers all the time. Maybe there's was a some bad machining at play?

 

So school me up. I was reading a for sale add on a crawler. Dude said he had 2.28 and 4.71. How is that possible?

 

Older pre Tacoma gen pickups were gear driven tcases. The crawler section of the tacoma crawlbox are based on that same gear reduction section.
What's nice about pre Tacoma tcases is that they are modular and therefore stackable. Ideally for that style setup, guys would keep the factory 2.28 tcase gears in the front gear reduction box and then install the 4.7s behind it.

 

Ahhh. Makes sense! Thanks man

 

There is a difference between mc 4.7 spline cut and tg 4.7 spline. A buddy just built his crawlbox using mc 4.7 gears with tg adapters. There's so much play with the tg coupler with the mc 4.7 that he end up buying mc 23 spline coupler. You can run it if you don't care. So for those that say there's no difference between mc and tg spline cut, your wrong.

 

My hole thing is availability. When I get the money, I want the stuff now. Not next year. Sure marlin may be superior but there’s plenty of guys (myself included) beating on tg gears with no issues. Run what’s available and forget about it. I’ve said it before and I’ll say it again. Way to many web wheelers who say you need xyz part to wheel but don’t even wheel themselves.

 

No one say you'll need xyz parts to wheel. If the option is there, wouldn't you buy better parts? True, it's useless to buy better parts if it's not in stock. But the funny thing is TG 23s 4.7 cost $629 which is more then MC 23s 4.7 at $569. Both are in stock right now, why would anyone buy TG? Pay more for less quality parts?

 

Man...all this talk about 4.7s

 

I'm thinking people are confused by the "different" term, they're the same spline, just cut to different tolerances.
