ht75 sprocket replace

MTS247

On the HT75 sprocket setup there are 3 concave/convex washers that i assume make up some sort of a basic clutch setup, any on know what order they go on.

i'm all googled out

(Manual calles it a "friction clutch")

Hi MTS247, I've got to be a bit careful giving advice on this as there are at least 2 versions of the HT75 that I'm aware of, probably more! The one I own is about 6 years old. On mine the washers are assembled like this: big one onto shaft 1st - then sprocket - then the 2 smaller ones. However, they do not act as a clutch. The saw has a dog clutch down where the engine & main bearing join together (please see pictures below) The first pic is an old salvaged engine showing the dog clutch, which is under where the white & orange shrouds meet in the last pic. Hope this helps!

Thats the same as mine, but as there is no spline for the sprocket to go on to, the preasure from the 2 smaller washers keeps the sprocket in place.
thanks for the order of the washers.
