lotus54 Posted June 10, 2020 Report Share Posted June 10, 2020 (edited) I have a customer 2012 Explorer (with fixer nut). It was stuck in 6th, I popped out the gearbox and found a broken gear. 6th drive gear tooth/engagement dog if I have it right. It appears on 6th the teeth just extend out to make an engagement dog. Not very thick there so seems a weak spot? But I always tell people to shift this slowly and gently and they will last great. Start ‘jamming gears’ like an enduro bike and you could probably break it in an hour. I had almost 400 hours on my Explorer (just sold it)- only gearbox issue was a broken return spring. Edit: Dang, I forgot the original reason for post. Who has gearbox parts? I have a call into Lewisport, but no answer back yet. I’m in the States.

lotus54 Posted June 30, 2020 Author Report Share Posted June 30, 2020 Adrian at Lewisport had everything- I just had him do the work, since he has done a bunch and has jigs etc. Quote Link to comment Share on other sites More sharing options...
lotus54 Posted July 5, 2020 Author Report Share Posted July 5, 2020 I carefully reinstalled the gearbox this morning. Along with clutch, side cover and a few other things. Fired up in just a few kicks, shifts great! Glad Adrian could fix the customer up at a reasonable price. Now to connect the computer and fine tune it, and make sure I got the list of other stuff fixed. Oddly, one that that didn’t work is the taillamp. It was wired up incorrectly- sure looked like factory to me. I could pop the pins out and fix. This bike has only 27 hours on it. good to get another OSSA back into use.

richardgg Posted July 29, 2020 Report Share Posted July 29, 2020 (edited) Send a PM to "peterb" on here... They don't have a website but do have some gearbox internals You can find him here on the Ossa forum and also the Vertigo one.
