I am putting back together my '93 VX transmission. While I was putting it together, the fifth gear syncho hub slipped out of the syncho sleeve. I had to put it back together, but am wondering if I did it correctly.

Each synchro sleeve has three sets of longer teeth (120 degress apart) that must be matched with the three sets of deeper grooves in the hub when assembled. Installing the synchro sleeve with its longer teeth in the 1st/2nd syncro hub slots will damage the spring ring. (this is a quote from the helms manual, sec 13-25).

If I can slip the hub into the sleeve can I assume I'm ok? If the teeth is longer, I assume it won't fit correctly until I rotate it and have the correct alignment. Please say this is true because I don't want to take the tranny apart again.

Thanks,
Gary

 

I think youre alright with that. As long as the gears are meshing and they are allowing to turn with out to much restriction... you should be fine. It should just slip together

 

Where's the Bense...

 

I'm a bit paranoid and am thinking about pulling the main bearing over the 5th gear syncho to check (have to buy yet another tool). My main shaft bearing (opposite of the input shaft bearing) went out and I replaced it (plus the countershaft and input shaft bearing). Because the main bearing wasn't there, it allowed the shaft to slip downwards so the 5th gear syncho hub came off the syncho sleeve when I picked it up off the ground to put it back in the tranny case. Args!

Just wondering, why are those teeth longer? There must be a reason for it.
Thanks for your prompt reply.

what's a bense?

Gear ratio and because of the force as well. When you are in 5th gear its a straight 1:1 so the syncro should line up and power should go directly from the input shaft to the halfshaft.

 

Are we talking about the same thing?

I'm sure I'm no longer in alignment, unless it can only go in one way. I doubt it since there's a mention about it in the helms. The longer teeth, in theory, can end up in the syncho hub slots.

I doubt it. It realy should just push together and sit flush. The longer teeth with mesh with the smaller teeth and sit flush, allignment really shouldnt come into play.

 

Here's more pics of the vx tranny project:

These pics are right after I cracked open the tranny case.

The syncho hub and sleeve are flush when I put it together today.
Well, I think I'm going to pull the main bearing to check to make sure I got it
right. You might be right that it should be ok, but since the tranny is still out, I
better make sure it's right.

Now I'm wondering if I should replace both differential bearings as well. Kinda costly, but the one on the passenger side is kinda rough and noisy when I spun it.

It is smart to double check when it's out though. You are right about that. I say get rid of the tranny though. The del sol VX always had issues...

 

Update: I pulled out the main bearing to check the orientation of the long teeth and I have it set correctly. It seems it will only go in one way and the long teeth will not end up in the slot in the synchro hub because the teeths wont mesh to allow it.

 

the Tech/Misc forum is for transmission posts; not the 92-00 forum. PM Bense; he's very well capable of answering these type of questions.
