Carbon synchros normal? (pics)
This is a picture of my carbon synchro.. The synchro slides down enough to where it touches the gear.. is this normal?
Here is a picture of my stock synchro.. notice the space in between the synchro and the gear..
Also since the synchro slides down more than the stock synchro... The synchro itself has more play in between gears allowing it to move around alot..
Is it normal for carbon synchros to do this? or Do i need to order another one from synchrotech?

Got a very quick response from David @ synchro tech saying the synchro is actually worn out. There should me a 1 mm space in between synchro and the gear cone it sits on.
This was causing me to miss shift at high RPM.

The blocking ring (brass part) should not mate flush with the gear surface. If it does, no friction will be transmitted to slow the gear down when the shift fork moves the collar over both parts, resulting in a clash between the gear and the blocking ring (grind).
The fit you have pictured is a completely unusable blocking ring. The last one appears near new. There is a gap specification for these two parts, and this gap might change slightly with aftermarket parts. Reference a service manual for the wear limits if you are not certain. 1mm is not an unreasonable new measurement.

Old thread.. i've already replaced the syncrho but here is a picture of the worn out inner carbon lining that caused the synchro to touch the gears.
