Installation Help - Control Sheave & Quadrant

mountaingriller · Post by **mountaingriller** » Mon May 17, 2010 3:41 pm

Over the weekend my 30+ year old shopsmith locked up - I know, I'm guilty of not doing proper maintenance over the years - Anyway, I called and ordered the Quadrant Assembly and the Control Sheave Assembly. If anyone has any installation tips or tricks I would really appreciate it.

Usually it will have instructions as to how to install it.

Pay particular attention to disassembly as well as assembly. If it 'locked' up, it may be a chore to get things separated.

OK, good to know - I'll be able to work on it the end of the week.
Is is best to remove the motor and work from the bottom of the SS?

If your unit is 30 years past due for maintenance, you might consider going ahead and pulling the motor and going thru the entire unit. In rebuilding my '55 greenie, I've come to the conclusion that servicing it periodically would be easier if I just pulled the headstock and took it apart rather than try to work from outside the machine. But then my old machine doesn't have the service access hole behind the logo. Just my opinion, but pulling the motor off is relatively easy and allows you to clean the quill pinion, inspect the wedge locks, and will make hooking the quadrant to the drive MUCH easier.

Definately pull the motor. Having just replaced the control sheave, I can definately say there isn't a lot of space in there. And make sure that the wires going up to the on/off switch are fastened down to keep them away from the sheave.
Last but not least, find the access hole and reoil the motor sheave. Mine had frozen up. I used a screwdriver to break it free, being caredul not to bend it.
While I had it all apart, I went ahead and replaced the switch

And while having the motor 'pulled', add a connector to the switch wires so they can be easily disconnected in the future when 'dropping' the motor thus eliminating the need to remove/reinstall the switch/wires.
