back gear spacer 003.jpgback gear spacer 002.jpgHave just acquired a myford super 7 & back gear spacer 001.jpgin box there was the change gear bush, change gear stud, spacer with cut out for woodruff key etc. Does anyone know which is the correct order in which these are set on the gear stud. I have att' a pic showing the bits I have. Does the spacer with cut out go at the end of the train before the lock nut/washer or between the bush & the sleeve? Thanks in anticipation DW.

Hi DW,

Put a gear on first, then the spacer, then another gear.

I had to look this up since I've never actually used the spacer. According to my manual, the spacer separates the 2 gears on the stud. Thanks for the prompt, one lives and learns - although it doesn't seem to be terribly important.



edit - too slow again

As indicated above it goes between two change wheels (gears) on the stud. The purpose is to create a clearance between the outer wheel and the inner wheel on the next stud in the chain.

Thank you all for your time, makes sense as when I look closely the woodruff key has a taper at either end so if put at the ends it would not contact the key. Off now to carry on cleaning setting it up. Regards Dave

This is very interesting as it is a Super 7-only spacer.

The ML7 which uses the same gears and studs doesn't benefit from the spacer - the edges of the gears do occassionally rub together.

So, Rod's observation that it isn't terribly important seems fairly accurate.
