Thread: Myford Super 7 clutch adjusting screw over tightened
23/11/2021 15:24:00

Dear All,

Many thanks for the replies. I suspect it's an early clutch and yes, I did try the "brute force" option but unfortunately no slippage atween the countershaft and cone pulley, perhaps insufficient brutality !

My only option is to remove the complete swing head carrier and try to dismantle the countershaft / cone pulley assembly in the hope that my actions have not virtually locked the cone / clutch to the shaft. Or I could leave as is and risk the early demise if the single phase motor with more frequent stop / start cycles.

When I bought the lathe in 2005 I'd reason to call Myford at Nottingham and spoke with David Auchell who advised on set up after a transcontinental move and sent me copies of Accessories & Ancillary Equipment for Series 10, 7 and 254 Lathes, Super 7 User Manual and similar for the Quick Change Gearbox. In fact from the serial number he confirmed the delivery date and address to first owner from whom I bought it from.

Dear All,

In my haste to adjust a slipping countershaft clutch I wound on the adjusting allen grub screw with the clutch in the "in" position, i.e. the disengage setting, refitted the blanking plug, then switched it on to commence cutting.

The clutch is now permanently engaged, the lever effectively fixed in the disengage position and worst of all the blanking screw hole no longer aligns with that for the allen screw to permit a back out.

Suggestions please as to how I rotate the the belt pulley with respect to the shaft to align both and permit access to that allen screw.

Any help greatly appreciated, thanks.
