Triumph Rattling Alternator
on: 15 June, 2021, 01:55:30 PM
Hi folks,
I raised this one before but never got to the bottom of it. I have an intermittent 'clatter' from the left side of the engine around the alternator. This happens regardless of the clutch being pulled in or out. I have only heard it at tick-over, although that is not to say it does not happen at higher revs.
A friend of mine googled it and found hits on 'Triumph Rattling Alternator' which apparently has a recall. Has anyone had this recall done or heard of it?
My bike is 2015 with 20K km.
Thanks!!

Not heard of that myself.  I think i'd whip the cover off and check all is securely bolted in and you don't have a foreign object in there.

Alternatively, could it be the water pump?

I just rang Triumph in Dublin and they told me they have never replaced a 1050 alternator. He mentioned it might be the sprag which I believe is part of the starter as they seem to give some trouble, but it is not on recall for sure. My model has never had a recall (2015). I'll have to open it up and have a snoop around...

Eeek! What was that, did he find out?

My first thought would be - look in the valve area, rather than the alternator. Can you use the tried old 'listening with a screwdriver' method to better locate it?

There was a problem with "Triumph rattling alternators" way back in early 90's when they fitted proper car type alternators & the bolt came loose, there was a recall, mine was done by a ham-fisted oaf, so the bolt head snapped off.

Could be owt eh, get yed in t'ava luksee.

There's another vid that explains what's loose in the comments, apparently the bolts holding the stator into the cover. Strange it's dated before the first vid:

Thanks guys. It is definitely in the side where the alternator lives. But it is very intermittent and sounds like there is something catching from time to time. It is not a clear clicking sound either, sort of hard to explain. I'll try to get a video of it at the weekend. Also I'll order up a gasket and pull the covers off. :084:
