Cougar Sv layshaft

[ian h]

Is it a good idea to glue in the needle pins to the layshaft before putting the o rings on. I ask because my first gearbox shredded when a pin came out!

Could you use roll pins instead of the solid pin? A good tight fitting one? Saw a couple of cars had these pins coming out at the weekend. Mine seems fine so far. Not sure why these were coming out. Any ideas?

My theory is that the original o rings are too soft and expand too much under the centrifugal force generated by the fast rotation hence the ring comes off or, expands sufficiently to allow the pin to fall out. Not 100% sure though.

Why not Carl? Fair play to schuey for replacing my damaged parts this time ( which suggests to me that they know this could be an issue) but I doubt they would keep replacing parts in these circumstances.

what happens when you need to remove them, check pin edges make sure there smooth (rounded of )

The first pins I had were fine and so are the replacement pins I have. Was thinking of using loctite retaining compound which I have experience with in other applications at work. This would defo hold the pin during running but one sharp tap of a pin punch would release it if necessary.

Steveb has had this issue too. So they replaced what bits?
