Manual disengage for a centrifugal clutch

[janvos39]

Here a drawing of a possible solution for building in the overrunning clutch.
I checked the catalog from Formsprag.com and found that they have clutches in the 6200 series of bearing dimensions.
So if we take a CSK 2RS 6206 than this size fits like in the upper part of the cross section. The lower part is the standard cross section. By welding a piece to the center and turn it on a lath the overrunning bearing and the support bearing (6006.2RS) find their place.
The aluminum cover - green in the drawing- needs some additional ring welded to it and than machined.
Also a new (brown) ring is needed with the rivets to connect to the drum. A special nut with an extension is also needed.
If there is enough interest I will do the version with dimensions on it.

Consider me interested.

Some suggestions. Take the dimension of the material that will be welded to the center and to the housing larger than on the drawing. After welding some machining is needed to come to the wanted dimensions. In general check the dimensions of your clutch against the dimensions of the drawing not sure all Suzukis are identical and there will be tolerances also.
For the overrunning bearing I suggest to use a loctite to attach to the bore and the housing. This can be undone by heating in case disassembly is needed.
The nut can be made from two nuts by welding a bush inbetween and turn it on the lath.
Between the two bearings a spacer is needed of 1 mm thickness.
I did not check the fit of the plastic cover. Probably a hole needs to made where the longer nut is located.

I hope this is enough to do the modification.

I wish I knew how to interpret those drawings.

I will print them out and go have a chat with Dayton, though, see what we can up with.

Suzuki made modifications in the size of the drum for the rearwheel clutch. Older models have internal diameter of 150 mm on which above drawing is based. New models (donot know exactly when they changed) have an internal diamter of 160 mm. Basically this does not change the idea of the overrunning clutch, but the drawing dimensions have to be checked for the newer drum type.

I was studying the possibility of designing an overrunning clutch in the gearbox on the outgoing shaft. It looks very well possible and therefor I ordered the overrunning clutch from the CSK series. Soon to be installed. Than at every throttle close situation the engine goes to idling, no more engine braking.See what that can bring on FE improvement.

Kill the engine entirely for even greater benefits.
