Hi can any one tell me what the circlip on the drive shaft is for, is its only purpose to stop it from falling out when you remove the final drive
-
Good Q Steve, never thought about it before but you probly nailed it. might also be to stop it shuttling axially inside the swing arm between splines to keep maximum engagement of surface area on both ends of the shaft.
-
the drive shaft dosent want to slide into the yoke with it on, is there a trick to it or just brute force
-
Steve,
There is a bit of brute force required to get the shaft to slip back into the yoke. I generally use a rubber hammer to knock it in, but check first to make sure the end of the splined section is started in the yoke and will slide straight back in when coerced in.
I just fetched my old driveshaft to get some photos for you in regard to your first question about it

Hopefully, the photo is clear enough to see the state of the splined sections

The end with the circlip has no wear whatsoever on it, most probably due to the fact that it's locked in position in the universal joint, as opposed to the back end....

where the splines slide fore and aft in the diff yoke.
I'd say that Jonesey is right on the mark with his reply, and that Yamaha designed it like this so any wear (like mine) will be concentrated where it's less critical, whereas if the front spline got worn like this, I'd hate to imagine the vibration from all the slack in the U joint, especially at speed.
BTW,
That driveshaft of mine is the culmination of years of improper maintenance, use of the wrong type of grease, and over 300,000 klms of worry free riding.
Just make sure to give your splines a nice coating of a quality MOLY grease before fitment, and you'll be right as rain.
-
yeah thanks for that i will persuade it go in with the clip on
-
no need for brute force,,,
if the clip stands to high out of its home, ease it off and squeeze it closed a little,
then all it should take is a firm bump with the palm of your hand to send it home with greased splines of course,
your right Jonesy, just stops it sliding

thanks i tried for 2 hours my mate Phill droped in and did it in 5 min but i did excaty what you said i compressed on circlip for a tighter fit on the shaft, the side car out fit is another step to being on the road cheers
