Myford Super 7

[KWILParticipant @kwil]

No problem with bushes, look on Bearingboys website for all sizes.

Sparky,

There are a couple of parts of your lathe which suggest to me that it is not an MLS7 but possibly an ML7R. I have a similar grey Myford and its a genuine S7. Id has different headstock bearings – yours look like ML7 style. Your leadscrew protector appears to be the tubular type. Mine is a short length of flat bar bolted to the end of the saddle at an angle to create a slope, making swarf + coolant run off.

What do you think?

Thanks Kwil, I will check them out for bushes. I need another bush for another project so two bushes will not make the postage seem so high !!

John. I have checked out many Super 7's on various sites and they all look like mine. I thought that the ML7 had removable caps on the headstock bearing? The swarf cover is of the telescopic type and was used on the earlier sevens.

As mine is a very early one could this be giving you the wrong impression?

Mike,
Your efforts are certainly impressive on this.

There is no wick down the oil hole in early drip feed machines!

Earliest countershaft/clutches ran on needle roller bearings and that is how you have picked up on the noise aspect. Yours clearly has had the bushes retrofitted at a date after manufacture. It was a Myford offer for all the early machines which became noisy; but not a free offer. A noisy countershaft would still work fine with no noticeable play, but sounded awful.

Hi Dennis, the worn bush is on the leadscrew, not the countershaft. My needle roller bearings are fine and quiet on the countershaft so I will leave them well alone for now.

mines the same as mikes and has the noisy needle rollers

Ive kind of learned to love the rythm they make as they go round
