Alternator Cush Drive Replacement

BAZIT · Mar 28, 2023

Hi
I have removed my alternator on my Trident 900 to replace the cush drive. The 4 bladed part which sits in the engine is retained by a single bolt ,this was slightly loose so I re tightened it ,as I removed my socket the bolt along with what looked like a splined shaft came with it .I immediately stopped and pushed the splined shaft back in .
I heard no noise which would have been something dropping off the shaft inside the engine and the 4 bladed part appeared to be back in place .
Have I averted disaster ?
Any one who has done this who has any info would be welcome .
Thanks

Hi, I think that you have a problem!! the splined shaft brings the drive to the alternator from the back of the clutch through the sprag and to the alternator. Both ends are threaded for a bolt, the alternator one you have the other end looks to have sheared off and the head of it must have fallen down behind the clutch.
If you have an early model with the lid over the sprag area you are in luck as you only!! need to remove the clutch cover and the bolt head may be there but you will still need to lift the lid and check that the spacers are still on the splined shaft ( very unlikely I would think).The gear train behind the clutch is fairly easy to get to once you have stripped the clutch , but the spacer behind the clutch is a right pig to get lined up again as you cannot see it and everything falls down, the best way I have found is laying the bike on its left side then it is just difficult but not impossible.
