I might have killed my Orion

I am confused about the spacer. I was running a 3 speed case behind a 465 with a 3/4" thick adapter when I took it out it had no spacer. I did not use one when I out it back to gether with the orion. Where I am getting confused is with the sligning of the gears. The gear that goes on the 465's output shaft is crrently aligned with the next gear in the transfer case. If I out a spacer on that shaft and move the gear out 3/4" than it will be 3/4" out of alignment on the next gear. What am I not seeing or understanding?

Does your adapter have a bearing in it???
 
no my plate adapter is the same as the one in lemon's post.

Here is a picture of mine before I took it apart. If I move that gear 3/4" out it will barley mesh with the gear it meshes with. You can also see the safety wire that was on mine it goes through the bolthead and then through the thick washer that the bolt goes thorugh. that washer on the back side has a key on it and a slot cut in the output shaft so it doesn't spin.

So what am I missing on the spacer and moving that gear out?????

Steve, aka Poser is the smartest man alive!!!! I will call AA and ask that they add a note for all who are running a non OEM transmission. You need a spacer just like Poser says. Here are the pics:

Thank you Steve I owe you one :beer:

All's well that ends well.

Other than machining your case a bit and running the chips through the bearings, there is no harm, no foul. Put that spacer in and you are done.
 
I'd like to see the next gear lube change ;) Glad to see you worked it out.
 
OK am I dense here or what - Treeroot - when you add that spacer how are the gears going to line up?

the gears are already lined up...the spacer will keep the gear from walking in towards the transmission and rubbing on the case.
 
On the GM SM465 the bearing is in the transmission. Woody's adapter plate goes around the bearing retainer of this bearing. The 420 adapters have bearings if I remember correctly. The splines on the output of the transmission flare out toward the transmission so on a stock setup, there is a tube that connects both the transmission and the t-case (both are male), and this keeps everything aligned. On the Orion mated to a 465, the gear walked toward the bearing retainer and machined the case. The pic below is about where the gear was riding in my case when it was "self clearancing". Also, in case you were wondering, the bearing retainer spins with the output so a spacer wouldn't be stationary, it would spin with the assembly.

Can someone post up a pic of what the Orion case is supposed to look like? I need a pic of the casting that is behind the input gear to the tranny inside the t-case. I am concerned that my gear machined off the retaining lip for the input seal.
 
Sorry that I did not get that out here for you Mike....things went south Saturday after we spoke.

It would look to me like the gear did remove that much material....

Treeroot,

What did you use for the spacer? did you make one or buy one somewhere? I guess I need one as well. I am confused by that still a little because there was never a spacer on my origional toyota case mated to an sm465 and I didn't seem to have that issue.

So how much for Poser to get me an Orion ready to bolt on and not leak and stay in gear??? :D

That is what I did, delivered to my house. All I had to do was stick it in and send him back my core.

so if I have the old school 420 adapter with the replacement output for the 420 from A/A I do not have to use this spacer? cool if so. I would preume that the bearing ( there was a second bearing and one on the end under the cone ) ineer race holds the input gear ?

John-


Are you talking about a spud shaft that slips over the 420 output shaft?


If this is what you are talking about, then you would not have to worry about the spacer that is being talked about in this thread, as that shaft replicates the Toyota transmission output shaft, and passes through the case, and the rear bearing in the transfer case.( the one behind the cone shaped cover ) You should then have a spacer back there, and a nylon locking nut to hold everything tight on the spud shaft.

My adapter has a bearing where that spacer sits...

So I suppose that I jus tneed that thin washer between the bearing and the input gear?

Also, when installing the seal in the t-case, does the spring in the seal face the transmission or the t-case? Does it matter?

I installed mine with the spring facing the t-case.....

Yeah. My Warden's adapter has a bearing there, too. So I should be OK?

Simple question for anyone that is confused. Ask yourself, can my input gear walk towards the transmission, away from your locking nut, and make contact with the inside of the T-case. You need to assemble the output gear on the T-case with your adapter (Sm420) or without adapter (Sm465) and see if there is a gap. In the pic below you can see the Sm465 without the adapter, and the input gear to the T-case assembled. This is exactly how it would be assembled with the T-case and adapter in place. I felt that the gear was good because of the press fit onto the tranny output, the flared splines, and the fact that it took a puller to get the gear off. I was wrong...

And I'm asking myself, if it was so f'n simple, why didn't Treeroot catch it when he was building it?? :confused: :confused: :D :D
