<VV> FW: 64/65 4spd question

[mherwald at mgwnet.com]

I have rebuilt a couple of 64/65 transmissions. In the course of doing so I
read Craig Nichol's article in the Corsa Tech guide regarding the evolution
from late 63 till 65.

The early 64's had a one hole cluster gear and apparently a unique clutch
gear.

The late 64/65 had a 2 hole cluster(countergear) gear and a different clutch
gear. 

 

If I look at each clutch gear they look exactly the same except for the
angle cut on the edge of the gear.

What is the difference in the clutch gears?

I learned the hard way because I tried using the later clutch gear with a 1
hole cluster gear and when I got the mainshaft in with a new front bearing
front bearing in nothing would turn.

Putting a known clutch gear from a known 1 hole cluster gear and everything
was fine.

 

Also what is the difference between the 1 hole cluster gear and the 2 hole
cluster gear? Aside from the hole they appear the same.

I tried measuring with outside mic's but don't think I got consistent
results due to the gear teeth.

 

So in summary what is the difference in the clutch gears and cluster gears?

And what works with what?

 

Thank you.

 

Regards,

Mel
