synchro spring install
What is the correct way to align and install synchro springs?
I am working on a WC T-5.

The way I found one, the little ends were both in the same key. Is that the way it should be or should they be in different keys?

Opps. Hate having to read carefully.
So that end of the spring goes under the key and hooks the side of it?
I assume lining them up on the same key is the way to do it.

The hook end of the spring goes into the cavity in the back of the dog, or "key" as you called it. I would install the hook ends of the top and bottom springs in different dogs, to prevent one dog from having more pressure on it than the others.

Are you saying I should put the hook end in where the other gentleman said not to put it? Are you refering to a different spot? Sorry about my confusion.

No, we're both saying the same thing.

I will have to take a look at this more closely and find the other cavity. The only cavity I know of is the underside of the key or dog or insert or whatever else we are calling those three little pieces. Thanks for the help.

Yes, that's what we're saying. Install the hook end of the spring (79) into the backside of the dog (81). Don't install both the hook ends into the same dog though. It probably wouldn't hurt anything, but it will make it a bit tougher to get the sleeve over the hub assembly.

That's exactly how they are to be installed.
Breazlan, facing the synchro, you hook one spring into the key at 12 o'clock, winding clockwise. Turn the synchro so the other side is facing you, install the other spring hook into the same key, and wind it clockwise. When you're done, they will be winding opposite each other.
It probably wouldn't hurt anything, but it will make it a bit tougher to get the sleeve over the hub assembly.
The reason you hook the keys into the same key, but winding different directions is as follows:
The key with both hooks has some force to the left from one spring, and some force to the right from one spring. If the springs would the same direction, the key would get cockeyed.
If you install a key with the hook of one spring in it, and the hook of the other spring in another key, the key will be unevenly pressed on by the springs, and you'll run into keys that don't move properly, like the 3rd/4th synchro in the Tremec/BorgW. T56.
I have an old T5 or T56 synchro around; hit me up if you need pics to help clarify all this.

I've installed them exactly as mentioned many times and never had a problem with a synchronizer in a trans I've rebuilt. That's the way I was taught to do it.
What you are saying makes sense logically, though.

In the video from hanlon motor sports and the tcc manual they install the springs hooked on the same key in opposite directions.
That is the "offical" way to do it. Wether it is better or not, who knows??
