Glenno I was going to suggest Loctite 263. I have seen it used on the front sprocket nut of my R6 track bike in place of buying a $40 nut from Yamaha... Stiff to undo but not a big problem. I think it will do your job nicely.

I have since purchased the OEM nut for the Yammie

AusMV312 Thanks Noel,
So I've fitted the flat washer and used Loctite 263. I put a drop on all contact surfaces...both sides of washer, underside of bolt head and of course the thread.
We'll see how that goes 😎

AusMV312,
If you can get a flat washer in there go for it ....
If you used thread locker and it didn't hold the parts weren't clean
You can use LocTite 271 BUT IT TAKES 500F TO UNDO IT, use 242 instead

AusMV312 I've found a washer that will fit under the bolt and increase the contact area to 100%. the head of the bolt still clears the opposite hub bolt on the alternator when the two hubs and cush rubbers are assembled. Should I use a Lock Washer instead of this standard flat washer?
I will use Threadlocker again as a secondary precaution.
Thanks in advance for any input.

Loose Again!!??

OK, so it's been nearly 12 months and a few Trackdays under my belt. I've had to remove the alternator again due to an oil leak coming from that region and my assumption was correct that "O" ring had failed. No problem, replace "O" ring.
I checked the Cush Drive centre bolt and Hub (Engine Side) and it was loose again The centre bolt was not finger tight this time so the Thread Locker I used half worked as there was slight resistance as I unscrewed the bolt.

I'm figuring there's an engineering issue with the design of this component regarding surface area. If you look at the contact area of the head of the bolt to the hub it may be just 50% which I think is the problem.....Any thoughts from the great minds that lurk in this Forum.

These photos are well within the limits of the website requirements but they look huge on the preview on my computer.... hope they adjust folks

silentservice703 Since you are using Loctite you shouldn't need a lock washer.

AusMV312 Purchased and fitted an NSK sealed bearing $8.50AU. It was very easy to remove and re-fit with some heat on the casing. I have used 'strong' Thread Lock on the the Cush Drive Hub centre bolt and torqued it to recommended 25nm.
I'm wondering whether I should put a lockwasher of some sort with that centre bolt. I'm at work for a week so I'll make a decision when I get back home.
Any opinions out there....?

AusMV312 Thanks,
Any suggestions on how to prevent the centre bolt from winding out again?
Or maybe, why it did it in the first place as the alternator rattle has been mentioned a few times in the past on this forum and it has been said, that it's nothing to be concerned about etc.
I'm sure glad I investigated the issue.

I'd go with a sealed one since the broken pieces of the bearing cage were floating
around

sealed 6005-2RS

AusMV312 I'm going to replace the bearing...should I replace with same bearing (SKF EXPLORER 6005 ???D) or is there a better quality option?
Appreciate the advice.
Thanks
