Removing the countershaft pulley speed 10 lathe?

[jon hill 3Participant @jonhill3]

Hi all

My Myford speed 10 countershaft pulley (the one on the same side as the motor pulley) makes a funny noise at low rpm. This probably due to mistakingly filling it with grease instead of oil. Rooky mistake which I left for sometime until the noise became noticable, so thought it might be time to sort it out.

Anyway I removed the primary drive belt and took out one retaining grub screw for the pulley but it still won't come off. Is there some other retaining screw or fixing? I have'nt taken off the grease nipple if this holds the shaft to the pulley?

Any ideas on removal?

Have you checked whether there is another grub screw hidden under the first one you already removed?

There are indeed two, 90 degrees apart.

[ALLAN QURASHIParticipant @allanqurashi51750]

sorry….180 (ish) apart.

Hi Ajax as far as I can see and feel there is only one grub screw per hole.

Allan on my speed 10 the grub screws are drill and taped 90 deg apart, there are only 2. Could be different on the ml10?

Anyway the pulley is still held fast, I have taken off the oil nipple.

Plan b is it advisable to put some light penetrating oil to displace the grease, clean and shot some more of the correct myford oil?

A 3 legged puller and some heat (hot air gun or paint stripper) applied to the pulley should get it off.
You really need to take the shaft out, clean and inspect it and the bore to find out what is going on.

Could be difficult, as there is only 5" of space between the pulley and window. Is it possible to use some forked wedges?

[Clive HartlandParticipant @clivehartland94829]

Socket set screw, cup point. could have raised a burr?

[jon hill 3Participant @jonhill3]

I got it apart, it came off quite easily with the 2 legged pullers I had.

Is there some sort of honeycomb reservoir for the oil in the shaft or bronze bearing? Also how do I best remove all grease and re-oil?
