Yup, I have the split collar. Good call Jeff, that's exactly why they don't seize. And yes, they are hard to tighten with the spanner wrench. Especially at that one spot.

I agree, I should just replace my heim's. After years of use they have simply worn out a little. As I expected they are squeaking again, a week after I used the lithium grease.

I must say, overall I have no complaints with my SAW's after several years of use.
