My engine is 1972 and the tranny is older.  So old it didn't  have the back up light switch in the nose cone.  My question is,  what size clutch does it take?  180mm or 200mm?
By Jeffrey P 655 Date 2012-10-21 13:22
Clutch is dependent on the flywheel. Measure that and it will tell you. Most likely a 200mm
By minivolks Date 2012-10-21 14:37
so a 200mm flywheel would equal a 200mm clutch?
By Brad H 1498 Date 2012-10-21 14:46
Yes, anything after 1966 will be a 200m clutch in the T1 based motors.

whats the difference between rigid and spring type?
By Jeffrey P 655 Date 2012-10-21 18:58
My understanding is the spring loaded one is a little easier on the tranny. Its a little smoother engaging. Either is fine for a street buggy.

The sprung ones have springs in the hub of the clutch disk that absorb a bit of hte shock when shifting. As Jeffery said, they are smoother and nice for a street car. They don't like abuse, I've blown up a couple from high rpm clutch dumps. The solid ones area solid center, the clutch material is bonded direct to the hub or sprung platesbetween the friction material and the hub. the aren't bad for street use, I wouldn't consider them harsh by any means unless you start getting into a 3 or 4 puck design or exotic materials (for racing) and they will stand up to some hp and abuse. I'm running a Kennedy 1700# clutch with a Cushloc solid disk in both my big motors. They work very well.

Thanks for the info.  My engine isn't a power house.  I will get the spring type.  Now to unbolt everything and get started.  It is an easy job.  Just as long as my back holds up.  Getting old.
