The Infamous Alternator Rattle

Well my 03 TB developed the alternator rattle a couple of days ago. I was going to pull it this weekend, but was able to take off early today so I just pulled it. This is what I found. The bolt head has sheared off. I was just hoping it would be loose. I found the bolt head with about 1/4" of threads and both washers laying there. Anyone know if this can be repaired (drilled and tapped). Or, do I need to find another alternator.

I had same thing. I had a machine shop get the bolt out and was able to salvage the threads.

Hi Zebraranger,
You can fix it at home. Same thing happened to me. Use this, I think I bought it at Homedepot.

I bought a set of those through Groupon a while back and haven't had the dubious opportunity to use them yet.

The original bolt has a locking compound on it, so use some heat first to break the bond.

Thanks for the links and the info, I'll get at it. Found a couple of older threads about it a little earlier today. Does anyone know if the bolt is a reverse thread?

I am in Orlando and getting ready to do this. How hard is it and any concerns?

Here's what I did.....

Last fixed in 2010 and it's still holding.

Before I used a longer bolt I had fixed this problem 3 times with the parts supplied by Triumph.

https://www.triumphrat.net/hinckley-...ml#post3001473

This is the Image from the Parts Manual.

#17 is the hardened washer
#22 is the Bellville washer
#21 is the Bolt (clearly shows an Allen head bolt). This is where I used a 12.9 Allen head 6mm x 20mm bolt to replace the Triumph supplied part.



Cheers,Denny

Wasn't there an update to the repair for this??? I've had my 97 TB for 7 years and I recall having the alternator rattle early on. From what I remember the shaft had bolts threading into it from both ends (alternator side & clutch side). When my sheared it was the bolt on the clutch side end. I believe the fix was a smooth-bore shaft with a long bolt going straight through and a washer/nut securing it.
