Stess Free Midi Anchor Winch

 Hi all,

Hoping someone can assist with an issue i have on with my anchor winch. I've had it for 12 years and it has never failed me. Until now. Problem-Motor works fine but the drum wont engage and spin under load. Light load its ok. I have half stripped it and found no issues so far.  I'm thinking that the worm drive on the motor shaft that drives the gearbox crown gear has stripped a retaining pin and it now slips. Has anyone had this issue or stripped a stress free anchor winch before. Stess Free dont open until the 13th Jan. Cheers in advance. Bunsen8
