Today I love BMW shaft drive just a little bit.
« on: July 21, 2016, 09:00:35 PM »
Was pissing down rain at 5:00 yesterday and I was looking forward to buggering off as it is show day holiday today in Cairns, long weekend Yee Hah!

Herself and I were going up to the wilds of Cape Tribulation on the grounds we haven't been there for a lot of years.


Anyway at 5:30 it was still pissing down, at about that time the bottle of Ballantines  I keep in the desk for "emergencies' started to look good.


By 6:15 it looked like the rain had cleared so I hopped on the mighty KLE and pointed it at home. Set off, changed in 2nd and there was a funny "rustle, rustle, thump!" sound and all forward drive ceased. The old tart has taken to jumping out of a couple of gears lately so I tried a few of those, but no forward motion resulted.


"Its blown the gearbox, or clutch or something was my first thought".


I got off and the 4 month old DID "racing' 520 chain was laid out for its full length about 15m behind the bike. "Bugger" was my second thought.


I collected the chain using a plastic bag that was conveniently blowing down the street, pushed the bike back across the street, went upstairs and located the Ballantines.


I then rang "Wayne's motorcycle towing", Wayne said he was having a brisk evening and would be about an hour, he then asked me "what is it and will it roll." I told him and asked "do you need me to load it?" to which he replied "no".


The first result of the evening so far.!


I said "I'm going back up to my office to wait, give me a ring when you are outside." Wayne said that was cool, so Mr Ballantines and I settled in for the next hour.


Wayne arrived in a nifty little people mover with a very low tilt trailer behind it.  I took him all of 2 minutes to singlehandedly run the KLE onto the trailer and secure it with a quite impressive number of tie-downs,

I chucked my shoulder bag, jacket, gloves and helmet into the back of the people mover and off we went.


Wayne said "you were not riding home like that were you?" I assured him that I wasn't pissed 2 hours beforehand when I was heading home, but if I wasn't pissed now I'd lose all faith in the Scotch industry. Anyway as we drove to Clifton beach Wayne took two more calls  from motorcyclists in strife, I asked if this was a typical night and he said that it was really because he hadn't been called to a prang yet, they were all breakdowns, or people too pissed to ride.


The fare from town to our place was $110, a bargain and about $5 more than a cab would have been. If it weren't for the 1.5 hour wait Wayne would be my go-to call on the occasions when "just the one" turns into a bottle or two at the conservatory bar.


Anyway, this morning I've put it back together with a new master link. I reckon the old one has an interesting story to tell.


There are two failures, although only one caused the chain break (the other probably would have eventually).

The non-critical failure was that the pins were devoid of lubrication, proving that bloody 'O" rings work both ways. When I assembled that chain I smeared grease all over the pins and the holes in the links and then could not get the keeper to seat, eventually I used a chain rivet tool against the flanks of the link to force them together enough to get the keeper on - in the process I reckon I must have wiped all the grease off and then forgotten to replace it. Those pins would have failed eventually from lack of lube.

But what did it in was the pin that  failed just below the groove cut for the keeper. Initially the link didn't break because the still fitted keeper held the outer plate on, but the inner plate would have been flexing ever so slightly it simply gave up just as I was going home last night.

I think I have every right to be pissed-off. I think I'll right to DID and see if they would like to come to the party with a new chain and master-link.

Think I'll write that one tonight - I thoughtfully chucked the remaining 1/3rd of a bottle of Ballantines in my shoulder bag last night and a bit of thinking fluid never goes astray.


Cheers

Wow, quite a failure on that.  

On the plus side - at least it failed while you were just starting out and not while you were clicking along at high speed.  Still, seems like something wasn't properly made on that link..

Ouch.  

And here I was thinking you would have been a single malt man Tony.  Work not doing so well?

Broke the chain on my Stornello a couple of years ago, it'd been soaking in gear oil for months during the rebuild. Snapped on a gravel hill.  This was my ride home, he just had his next load cancelled as he drove past.  I had to push it the last  2km home.



The chain had only done 14,000km....but is over 40 years old.

My preference is Glen Livet, but any port in a storm . I usually keep a bottle of Chivas or even Teachers in the office, someone gave me the Ballantines - it's actually not too bad.

I miss the drips and associated mess of lubing chains so much so that I added a ScottOiler on the R100S.  [smiley=mad.gif]

The chain on my Z900 snapped at slow speed just before I sold the bike. It was a huge 630 so you'd think it would have been strong enough.

Scary things chains, I often wonder how the Moto GP bike chains survive all that power.

Tony,
You need another bike without a chain. This is five minutes away.

Barry I agree. What peeves more more than a little is that I don't skimp on chains.  Anyway, I've decided it was a random bit of bad luck, it does however point out that the keeper groove is a potential failure point.

Funny thing is I have a tool to peen rivets that I have used exactly once in the 40 years, in fact over the years I have amassed a decent collection of rivet type master-links that I have never used because they are so "in-convenient."

I may rethink that in the light of my failure.

Not really tempting. Much as I always wanted an LS I'd rather buy (in descending order of want) and R100/80 GS, R75 or R60/50.

If I had someone falling over themselves to buy my R65  maybe, but I made some very dumb decisions when I put my R65 back on the road and as a result the cosmetics are shite, which in retrospect is a pity because mechanically it got a 1st class "birthday' and did spend 20 years under my back deck not wearing itself out.

You could boil your final drive in Duckhams if it made you feel better Monte.

On Friday I untangled the chain and gave it a good clean. After carefully looking at every link I put it back on the bike with a new (and non-DID) master link of the riveted variety.

Whilst doing so I contemplated how long since I last used a riveted master-link and came up with 1979.

Anyway, we did a quick trip to Cape Tribulation for lunch with no chain related problems.

I'll keep a close eye on it however.

The old manual that came with the '53 T100C spent a page or two detailing this nasty chore.

Except for the bollocking you got of your mum for doing it on the kitchen stove, I didn't mind the boiling in grease bit so much, it was the cleaning it before hand that was the dirty job.

I never did it again after the 75 Triumph T140V as Japanese bikes came with an O ring chain and no split link.
