Re: Gearbox Key

Just because a tooth on the lock ring lines up with then keyway doesn't mean your key is safe. That's an assumption that 228 made last year, only to have the machine key fall out when it slid through a gap in the teeth (somehow the lock ring rotated).

If you use a [tight fit] washer with the lock ring, or alternately a shaft collar, you can prevent this. The CIM shaft is 8mm diameter, which is only a few thousandths larger than 5/16"; you should be able to use an oversize tolerance 5/16" washer.
