Broken Clutch hub post!!!

[671M900]

DAMN DAMN DAMN....

Haha. So I was installing new clutch springs, and I'm turning the third bolt in, and next thing you know, *KERRRACK* clutch bolt post snapped off.

NOw, I've read people removing half the springs to lighten the clutch pull, but it also reduces clamping friction. Can I get away with one spring broken off while I wait for another clutch hub?

People remove the opposite spring to keep the spring pressure even when they pull the clutch. If the springs and plates are in good shape the clutch won't slip according to people who have tried it.

Go easy on those spring bolts and use some lube ( a little hi temp grease or anti seize product) on the threads. Strong finger or medium hand strength when tightening. I  figure that those allen bolts are under spring tension.

Go buy a nice light weight clutch drum if you can't get a bargain on a stocker. Reducing rotating weight is a good thing whenever you can. If you get away with it and don't want to spend, saw off the opposite post and use heavier springs (a tight arse like me comes up with those ideas).

Found one on ebay for $25, listed as fitting 919, 996, 999 etc... Double checked the part numbers, and those three, and my monster 900 share the same part number. I wasn't turning them in much either, I went finger tight and put the socket on, and bam, snapped!

Hmm, heavier springs, where does one go to get such springs, and what's the regular spring rate of the stockers?

Assuming the rest of the clutch is in good shape, you can run it with 4 springs.
Lever effort will be less, but it doesn't grab quite as hard, in my experience.

You can leave it sit with 5, but don't be pulling the clutch or riding it.

Alright, so just remove the opposite spring? It's not a track bike, nor a race bike in anyway, yet. Will mostly be used for my commuting and sunday rides

Yes, just remove the opposite spring.

Put the socket on it? Oh no no - the torque spec for those are 5-7 Nm which is almost nothing.

I once machined new posts that bolted on from the rear of the hub while I waited for a new hub... granted that was after sliding on the clutch side and shearing off 5 of the six posts...  But yes, it can be done.

The Barnett springs that came with my plates were stiffer and didn't rust.
Board sponsors would have a range of better springs than the rusty old stockers.
