Norton Commando Clutch Packs
By David J. Comeau 24 Aug 2000- Rev. 29 Dec 2004
There are basically two variations of clutch pack in the Commando.
First is the early style THICK friction plates and are used with
the THICK pressure plate.
Next is the late style, which used the THIN friction plates and the
THIN pressure plate.
Plain Clutch Plate
Both clutch variations use these steel clutch plates 06-0746=.080”
Early Qty =3
Early-thick .145” friction plates Qty =4
Thru 70- bonded segment 06-0749
71-72- solid fiber 06-1339
Barnett- bonded segment-thick # 524-68
Late-thin .125” friction plates Qty=5
73-75 Bronze 06-3741
Barnett-bonded segment-thin # 524-73.
Early THICK pressure plate 06-0745 =.347” thick
Late THIN pressure plate 06-3768 =.227” thick
To derive the full clutch height you add all
the seperate components including the FULL height of the pressure
This is the FULL dimension filled by STACK HEIGHT
of the components, between the backing plate in the clutch basket out to
the diaphragm. From an engineering stand point
this is the correct number.
Early clutch, original stack height=1.167”
Late clutch, original stack heigth=1.172"
