Another 149 Rebuild

What it sounds like you are saying is that the basket pulley is not solid on the engine crankshaft. If that interpretation is correct, well it should NOT move once tightened down with the allen screw. If the pulley hub is moving on the crankshaft, your square key must be sheared. On the other hand, if the hub is solid on the crank and the pulley moves, then the hub/pulley weld must be broken.

Get that sucker off there and see what's worn.
Sounds like the keyway on the crank and/or the pulley itself are about to bite the dust, or, the key stock itself is badly worn, or a combination of all three adding up to lots of slop.

- Your interpretation is spot on. I can't even see the key, I had to slide something up the slot to feel it. I guess I have to pull the bearing off and check it out. Thanks for the guidance.

Nice job on the air cleaner!

Thanks. I know it isn't for everyone, but I thought it was tasteful.

Well I got it torn apart and discovered a few things:

I think the weld broke since the part with set screws spins 1/8 of a turn back and forth.

I think I should replace the collar and flange, they don't seem to lock together.

I'm not sure sure how long the key should be, but the one I have only fills the void under the pulley, should it also be under the collar?

What do y'all think?

[finsruskw]

It's probably the original key, only needs to be under the pulley assl'y as that is the only part that is keyed to the shaft. Parts lookup should tell what exact length if that is a concern
The collar is an eccentric lock and not a thread as such, I can see why some would call it that though.

If the pulley and basket part are not overly worn enough to throw the whole assl'y out of kilter and unbalanced enough that it would come "unglued" if re-spot welded, I would give that a try. Any body shop would be able to do that in about 5 minutes.
If not, it would call for a replacement.

Thanks finsruskw. I got four small spot welds on the basket, hopefully they hold. I also got some more painting done. Ready to get serious about reassembly.

The new paint looks very nice!

Nice work!
