Drivetrain breakdown

[Clutch]

Hey clutch,
How did you go with getting the clutch cover off without draining the oil? I've got a minor clutch slipping issue, and might need to do the same if it gets too regular.

yeah! no problem, think I used 3/4" board under the wheels and you can see the oil  is just below that section when you get the cover off.

Thanks Pete,

I had the rear wheel off mine ( new rear tyre/ switching back to 16") and decided while it was off, I'd have a good look at everything that moves in the swingarm area. Pulled the diff and extracted the driveshaft. Then went for broke and dropped the whole swingarm out to lube and reassemble the bearings in the pivots. I noticed that the rubber uni joint cover had oil sitting in the bottom of it, so further investigation of the middle drive seal is required there. The oil level is still where it was when I changed it some months ago so it's not likely to be a real drama.
The driveshaft, on the other hand is a bit of a worry. Since reading this thread, I'd been meaning to have a look at things in there, but haven't had the time to do it.
In the past, my maintenance for this thing was to pull it out occasionally (maybe every 3 years or so) and fill the diff flange socket with grease and plug it back in. This time, I cleaned all the old grease off it and inspected the splines and this is what I found.


Though not worn to the point of having sharp edges on the teeth, there are visible steps in them


This looked fine when I pulled it out with grease covering the splines.


It's when you clean all the old grease off it that the wear becomes evident.
In its defence, this shaft has done a lot of klms (Bloody near 300,000) and considering it slides in and out a bit with each movement of the swingarm, it hasn't done a bad job over the years.
BTW - The socket that holds this end of the driveshaft had no visible wear in it, oddly enough. Must be made of a harder material.

G'day Xtian, I have just replaced the entire drive line from uni joint back due to exessive wear in all splnes ( it was all used parts so could have a bad brg but I had noticed the vibration before just not as bad) as I said only done only done limited kim's so far ( maybe 800 km's) ,I did do half of that 300 km's two up which added to the load.  and had no clutch slip??
  will keep you all posted as to what I find as I work through this.

Middle gearbox does get hot.

I had a similar problem and due to lack of flexability (old broken bugga) I did not track it down to the final problem but changing the uni joint back (swapped the rear from one of my other XS's) fixed the problem

thanks Aussie,
 Did another 300km's yesterday, did notice that "slip" a couple of times but really think it's in the gearbox/selector, seems to be only in top soon after selecting.
 have noticed a "growling" vibration between 3500-4500, feels like a bearing.
2 1/2 hours after getting home I found the middle gear box was the warmest part of the engine, I know the oil is good and there was no metalics in the old oil, think I might replace it to be sure and narrow down this vibration.
 I will have to check out this band, any band named after me can't be all that bad.

Hey Clutch, I read your comments, believe me if you have the same problem you will hear it too, generally on the throttle off as you slow down, sounds clunky.
The problem is certainly fixed , with a new driveshaft and rear "universal block"fitted and I must say it feels bllody good and for the first time in a long time (marvelous how we get used to little issues), the bike responds immediately without any issues in the driveline.
It is running really well. And as Jonesy said- we went out for a little "play" and no issues. I put a new clutch in mine prior to all this as it was slipping too, and Im glad i changed it out. But remeber when you toughen up the top end  /clutch /tune, then that extra power is going to highlight any old issues you have.
Good luck with it!!

PS- Clutch is the name of a US rock band- awesome -check em out all you rockers out there!

[Jonesy]

Hey Clutch,
I'm pretty sure you can, just to be sure you could park it on an old fence paling or similar to get that extra lean but still not to much

[Clutch]

G'day Jonesy,
     yeah I have noticed the clutch slip ( seems to come and go abit ) but this is a different feeling, there were no signs of metallic wear in either the eng oil o rmiddle gear case. My last xs had more than 200k on the clock but nowhere near the wear this one had in the driveline
 I can't remember but can I remove the clutch side cover without dropping the eng oi when on the side standl?
 I have the clutch plates but need to check if anything else is worn in that area.

Hey Clutch
As mentioned earlier in another topic somewhere......I took your bike for a test ride when it was up for sale and thought that it had some clutch slip. so its probablt a good decision you made to look in that area. If it any consolation my clutch is slipping too but probably in tihe illega,l playing, speed zone.
Oh yeah by the way, that was chasing Grant on his XS after the repairs....he didnt complain about any sprocket slipping noises.

G'day Aussie,
  just like to know if you have that bike back on the road yet?  I'd like to know if the first indication of a problem " like a chain slipping a tooth" that you mentioned is gone.
 I just replaced the entire drive from uni joint to wheel spline, as it showed signs of maybe going the way of yours did ( I have never seen this before either but then I have only seen inside two xs drive lines) but after riding I have noticed the occasional " slipping chain " feeling, no noises, no more xs backlash , so now I'm a bit more worried what I might find or rather how far I will need to go to find it.
  Next job is to do the clutch and have a look around inside the cases for any signs of wear/damage.                  Clutch.

Aussi
is there a fuel tank available locally?

[Aussiexs11]

Guys,
I got the parts I needed locally, and I will take a few photos and post them, its an unusual problem apparently.
Thanks.
