727 clutch clearance

[Zwap]

My -66 Service Manual says .024 to .123 clearance in front clutch and .037 to 0.060 in rear clutch, should I go for the low side of these?
With new clutch plates I got .080 clearence in front clutch and 0.038 in rear clutch, is it OK?

The Service Manual also says 10 springs in front clutch but when I teared it down there was only 7 springs, should I add 3 springs or should I keep the 7 springs?

So for a thumb rule you can say .015 per clutch.
4 clutches .060, 5 clutches .075 and so on.


The springs in the Front piston don´t have to be that much, but 7 is a littlebit weak.
go for 9 or 12.( KD Lever 3.2 or 3.8)
When you have a high ratio KD Lever,Like 4.2 or higher, add more springs like 12 or full equipped.

Ok, same thumb rule @ the front as the rear clutch?
The KD Lever is 3.8, then I can go for FSM recommendation 10 springs.

Yes, thats the same rule
If you go with 10 springs, you will be fine!
