In the process on stripping my primary to fix that leaking main seal and found some loose hard bits in the bottom of my housing. Pulled the stator off and found cracks in the insulation, and what seems to be a bit of insulation has come out. I thought I might have fryed it when the wire broke off halfway between Te Kuiti and Taumarunui last week, but when the wire was fixed , the charging was fixed as well. Is this going to be a problem if I refit it.

PS rotor looks good.

Just reglue it with some Arildite or simlartwo pack glue.

+1. ...any two part epoxy should do. I would avoid the quick set type.
Be sure to degrease and de-oil it first.

Slick
 
I would not use 2 part hardening brittle epoxy but a sealant that stays slightly flexable as I've done to repair a couple of primary damaging evens.

That's what I've used. When the wires eventually break you can carefully dig out the old wires with a utility knife and solder on lamp cord. It's insulation appears to hold up as least as well as the original Lucas stuff. I have two stators that I've repaired like this. I carry one as a spare on long trips.
 
I have been away again for the weekend, and realised I should have said the epoxy like surrounding the stator is cracked. I agree with the above in using apoxy on that area, also using a softer compound where the wires come out of the coils. Just needed a bit of confirmation that this was not serious.
Many thanks for your replies.

Now to the serious work of finding that new main seal I bought about 2 years ago. Everything else in the primary seems ok.
BTW, I found the 3 bolts holing the primary to the crank case were loose. Reason for an extremely slight weep in that area.
