WAS THIS ADDED BY THE GUY WHO INSTALLED THE FLYWHEEL?

Among the parts I took off the bike when dissembling to check for damage, I found the following 'washer, as per manual or parts catalogue, this doesn't belong anywhere, or?

Whereabouts on the bike did you find that?

with the flywheel assembly . . . lemme fetch some pics

[DarkMonster620]

Here,



It was in front of the flywheel when I took it down . . . Never trust someone else to do your job . . .

[Speeddog]

Oh. 

That's not right at all.

Was that a Nichols flywheel?

OK, almost on final assembly, just taking my sweet time while I work on other customers bikes to earn a living . . .

Installed OEM flywheel . . .

I take it this washer was the cause of the damage that you were looking for? What ended up happening?

I take it this washer was the cause of the damage that you were looking for? What ended up happening?

Got to the shop one day, stopped the bike, no noise, no nothing . . . come 1400h, want to go home, hit starter button, just heard a buzzzzzz . .  had to kill it via kill switch.

It was "diagnosed" in the forum that it was the starter clutch since there was no start . . . when I received all the new parts I ordered, with dealer discount, I discovered that the issue was that the nut holding the flywheel had come loose and eaten away the aluminium flywheel, when all parts were taken off to clean the mess, somewhere in the forum you can find pics of it, this humungous washer shows and suddenly I am at a lost and have NO idea where it goes, I printed images of the manual and parts catalogue, nowhere to be found, so I already assembled it without this washer.

What I am assuming is that the guy who did the job, I had no time and at the time didn't have the flywheel locking tool which this shop, don't ask me how they had it, had it and the owner is a good friend and he was the previous dealer's service manager . . . I can only assume that since the 'mechanic' thought that the flywheel was 'smaller', it needed this extra part to hold it . . . Damm it lasted well over a year, almost 18 months !!!!

So now, back to OEM flywheel and goodbye to the faster accel I had for 18 months . . . I think anyways that for the traffic here, the OEM might be best . . .

the early 3 phase alt bikes had a lump on the back of the flywheel and the bearing sleeve inside the roller bearing inside the was just a sleeve.  later, the lump on the back of the flywheel disappeared and the bearing inner sleeve had a piece put on the end of it instead, so it was a stepped sleeve.

if you bought a dp flywheel it came with a spacer like that, which would be needed if you were fitting it to an early bike which originally had the lump on the flywheel and bearing sleeve without stepped end.  as the dp didn't have a lump on the back.

maybe someone saw it and thought they had to use it.

i have seen aluminium flywheels loose their splines due to the nut being not tight enough.  like 180, not 270nm.  as the aluminium frets a little, more torque is lost, more fretting, splines start banging, etc.
