XV1000 84 odd spring in crankcase (pictures)

PostAuthor: Mrljack » Thu Jan 25, 2018 11:47 pm

Problem is, while opening the crank case to change the starter, a spring came off and I can't find where it come from.
It looks like it could be one of the six behind the flywheel. Although the flywheel seems well installed, it would be weird the spring just came off.
I linked pictures of the spring below. Could it be from elsewhere in the crankcase? I can't find anything in the manual related to this spring.
I did not disassemble the flywheel, since I want to be sure of its origin.

Thank you in advance!

Flywheel retainer springs&dowels.PNG
Damn...never heard of that one. Sure looks like it. Same number of twists and size. You got six on the right side, too. Off cam gear. Never had the (pleasure?) of breaking down this far, but thought there were same springs as retainer/shock springs. Only thing I've dug into on right side is clutch basket. Those springs in the drive gear (clutch basket), I thought were bigger. Been awhile. I don't want to get too deep in the weeds in an area I'm not all that familiar with on the right side. Hopefully someone with more experience this deep, will get chime in.

with nothing for size reference, best guess is #3 ---> https://www.mrcycles.com/oemparts/a/yam ... haft-chain

Yes I think that would be the spring (90501-21133-00). It's about 1,1cm long by 0.9cm diameter. Thank you!

Now I have to figure out why it was out there... I think I won't have other choice than opening this thing some more.

Changing the starter was the further I went so far! :P

I'm guessing you already pulled the flywheel because that's where those springs are located. Otherwise the PO or prior service person left that spring out the last time the flywheel was R&R'ed. The flywheel and cam drive gear behind it should be pulled together to prevent the springs and dowels from spilling into the crankcase.

That's also what we though but we just did removed the flywheel and all springs and pins are in place. Now I'm just guessing that the PO changed the flywheel and somehow left one spring inside the crankcase.

Wow..good damn thing that (extra ?) spring was heavy enough not to get sucked up into the gears or anywhere else. It's hard enough to break some teeth or whatever.


Edit: Let's just hope that was a 'leftover' spring.
