33K, Driveshaft Replacement

[deanmichele]

Hey guys, I have just found my spline in a bad way. I have had the bike serviced regularly the whole time. Do we have a reference to the maintenance bulletin from Triumph instructing dealers to grease the spline. I have asked Triumph Australia to assist.
Cheers

Just imagine the poor guys who have the Carpenter kits!!!!!!!!!!! 240 or 210HP will really screw them up if it's a heat treating problem, or an under engineered drive shaft!!

ONE customer has 47, 000 miles on his 265 hp Roadster and no driveshaft problems so whats going on with

So Josey, are youy you implying that you pull that square tire off every 6-10K miles to grease your splines?

I suspect that yours and rainman's and prolly a bunch of other Darksiders have forgotten to perform this necessary maintainence routine regularly, which just happens to need to be done at about the same time that most motorcycle tires require replacement.

YES exactly

Almost an even trade and extra Rocket III parts will appear on the Classified section if I go through with this or a Scrambler.

Bye for now.

DONT know whats up with your bike how often did you lube the driveshaft ?

I can see it has had the update kit in it from this picture and the one below.




Looks like the gears been hit hard by the dogs of the male gear would like to se ethe pictures of the mating male gear if you have it. I am interested in how the dogs that mesh faired out.

On the plus side this is definetly fixable.

These engines are tough






But they do break, mine is my fault as I am the one who decided on this search for maximu horse power .

WELL do not use the **** lockup clutches they are the cause of these failures

Rust could not form in that thick of a configuration at that wear point for one thing. Its the really thick RED synthetic grease the mechanic uses. My issue now is, are they using the correct grease or whats sitting on the bench in a Harley shop. I bought the Honda stuff for the next one.

Sadly, I fear that there is some other issue at work here. I go now to look at Japanese offerings.

Dont know what that was but obviously no good find a better shop to service your bike

After reading the posts here regarding the spline failure on some of our Rocket drive shafts, I think EVERYONE should remove their final drive unit, clean and re-grease the shaft splines with a high Moly content grease. Regardless of mileage. Triumph may have a heat treating problem with some of their drive shafts on the Rockets.

I posted earlier when I replaced my rear tire I removed the final drive unit and cleaned and greased my shaft using Honda M/C "Moly 60" paste. There was a light blue colored grease on the shaft splines from the factory. High Moly content or regular grease I'm not sure.

I know there are higher Moly content greases out there, but the Honda M/C shop is close to me and I've not heard of any shaft spline failures on Honda shaft drive motorcycles. What say you?

ALL shaft drive motorcycles require lubing the driveshaft every 10,000 miles so if your running car tires remember to do this with the proper grease not some crap that some Harley shop uses

Think I will trade my rocket for something more reliable like a Yamaha!

THEY have shaft drive bikes and you have to lube them also with the CORRECT grease

Every 10,000 miles home boy.

Okay....so here is my comment and question. My shaft splines were not lubed at my first rear tire change at 7K. I'm sure the guy I had swap the tire out didn't do this. I plan to do this at the next tire change as I will be jacking up and removing the tire myself this time. In looking at the service manual, it looks like I have to remove the rear shock bolt and the 4 other acorn nuts to remove the bevel box to allow access to the driveshaft spline. My question is...once this is done, does the whole drive shaft pull out so you can access both ends or not? Are we talking about just lubricating the bevel box end of the shaft or somehow doing both ends? Does the shaft somehow receive lubrication where it attaches at the engine? The manual addresses the specifics about making sure you insert the axle shaft before tightening and torquing the bevel box bolts , but I don't see much as to whether the drive shaft pulls out. Are there any pitfalls I should be aware of when lubing or more specifically assembling the drive shaft back on the bevel box? This will be on the touring model, not the roadster.
