Although I never had any problem with my original (2009) Carrier Assembly, apparently Mat had the same needle bearing issue I'm now having after I changed to the revised Carrier Assembly, per Triumph advisory. Mat's solution was replacing needle bearing and race with three ball bearings and a spacer (leaving out circlip in hub's 37mm bore).
Revised Carrier Assembly (replacing all previous) has a smaller 35mm bore, thus a smaller needle bearing and race. And now I have the same problem Mat was chasing in posts linked above.
I was able to obtain three 20mm x 35mm x 9mm bearings, but chose to go with two 20mm x 35mm x 11mm bearings and two spacers instead, allowing install of circlip. (The three-bearing mod impinges on circlip area.) Both sets of bearings came from VXB.com.
If choosing to do this, please double-check and triple-check all dimensions before proceeding.
Pressing needle bearing out of hub requires a precise diameter drift and significant pressure. Someone here managed to cut one out. Removing needle bearing is first challenge; replacements are no longer available - bearing failure means replacing entire Carrier Assembly.
The ideal solution would be a single roller bearing: 20mm ID, 35mm OD x 25mm long - unable to find one of these.
(20mm x 37mm OD x 25mm with thrust bearing looks interesting, tho: Link )
Problem may be caused by too-tight belt adjustment; I've been setting tension to 3/8-inch (same setting HD uses), where Triumph shop manual specifies 1/4-inch. Next adjustment will likely be closer to 1/2-inch.

Not only was it tight in the bore it was also corrosion welded. I can't remember the mileage when I did this but it was right after Matt posted his solution and the last time I did an R&R on the hub it was way easier.

Annoying that all they had to do was to have a bigger diam. pulley fitting and they could have put a full bearing in there .. like the other side.
Good work though .....if mine goes and its this version I shall do this. It will work.

I don't know if original hub had a 2nd circlip in its snout or not, I don't see it or it's groove in your drawing, either. Might show up in parts list for the now-extinct version, but version 2 is the only one available for 2010 (and possibly later models). No clue as to why they went to a smaller needle bearing, but there it is.
Never had any issue with original hub, but I now have four of the new ones. First failure shows obvious wear on inner race; when we pressed it out, one needle bearing seal was separated from bearing, hard and brittle as metal - thought it was a washer at first. Seal caused failure, or bearing cooked seal, dunno. Replacement hub lasted about two weeks before making its familiar noise. Don't think I can wait for tire to wear out, will have to install modified hub soon.
Throttle is smooth as silk, and wheel adjusters still provide finesse - thank you, Mat.

| | Posted : 14 Aug 2023 - 20:39 Post title : Re: Mat's Hub Mod - modified (Re: MotorMac) | | | I am sure mine gave up because of water and dirt ingress. Pretty harsh road conditions where I live. My 2015 seems OK ... but I dont do the miles I used to as I have another 4 bikes to ride ... and I tend to do local rideouts on my new Fantic Caballero which is much more suited to our back roads (and farm tracks )
But its good to have options when needed.
