Flywheel question....

It seems there's no threads in my flywheel like normal.

Trying to get the crank out to the shop to get a new rod in it and I can't seem to get the flywheel off.

I have the normal 27MM puller i've used hundreds of times but this beast seems to have tricked me :thumbsup:

Anyone know what the deal is here?

Thanks in advance!

It may have an add-on weight that threads into the puller threads and then bolts to the flywheel. If you see a pair of hex bolts on the outside surface, that's probably the case. You may find, if those exist, that you can remove them and unscrew the weight (remember the puller threads are left handed), which would give you access to the threads for removal of the actual flywheel. If it seems stubborn about unscrewing, you can use a plate-and-bolt type wheel puller in the holes the bolts came from (carefully).

Just wanted to throw an update...

Apparently the flywheel "puller threads" are covered in some kind of compound, once i just tried threading it in... it cleared the stuff off and it's off now.

Another Question tho, I'm going to suppose i need the Crank puller to get the crank out of the bearing? the timing chain gear seems to be the same size as the ID of the main bearing. (I thought I remembered in the clymer manual that i'd need a puller, just can't find the manual right this minute.)

I have just had my bike apart.

While the gear looks the same it is slightly smaller and will clear the bearing OK
