Lube the splines...

[Kevin frazier]

Triumph did a good job of making this part of bike, like all of it really, much improved, very strong looking differential and torsional damper end. Very impressive

For anyone doing this do both ends. I got my grease this morning so I dropped my wheel and new metzeler to my tyre guy. As luck would have it all 4 diff studs came out. The flange looked pretty clean but I could see a few if the splines were shiny and not much grease to be seen.
I decided to look at the other end and there was nothing there. Slightly rusty and some polished splines again.

Don't short cut do both i

****, I didn't even think of the other end.

Simple to do. Remove the heel plate and cover for the starter. Remove the brushed alloy cover and there a plastic cover over the universal joint on the shaft. If you squeeze the cover with your hand you should be able to get it under the lip and pull it out

How long does that spring do exactly what its supposed to?

I am guessing that it is to hold the drive shaft against the transmission
i doubt that it is spring loaded more like a small bumper spring.
and of coarse i have never added a spacer to see if this is true.

Good question. It should probably be replaced at some point ( when?). My Roadster had one too. Just saw @TURBO200R4 response. He’s no doubt right and could be good for the life of the bike

Excellent - thank you. On the Roadster you had to remove the swing arm - a total PIA. This sounds more like it.

i usually keep an eye on all the threads and have never seen one that was broken
i doubt if it gets used that much under normal conditions
Kevin probably tortures that little bugger.

There might be a few gouges in there but my cush drive is shimmed and tight

I actually didn't look into whether or not it even had splines at both ends. I thought one end would be enough to accommodate the bit of movement it would need for the small swingarm arc. I wonder if the splines froze at the engine side, what would happen. Or how much movement each end has

that is a good question
i only weight about 150 lbs and have a light weight spring on the bike so it is going to move with the full swing.
may be i will check the next time a change tires (going to be a while be i just put new rubber on)
i am guessing that you could use different length rods to find out what the clearance is (how much space is there)
