Clarke bench drill, is spindle nut reverse thread

[Mel769]

Hi all, great forum and hope someone can help

Ive got this old clarke bench drill and need to remove the spindle nut which is located (at the top of the machine) in the hollow of one of the pulley wheels. I have finally found the right size socket (which is a 32mm, had to grind the sides down so it would drop in) but the nut's really stiff. Anyone know if it is a reverse thread on these spindle nuts ?? Thanks

If there is no sign of a tab washer, then it should be a left hand thread to prevent is unscrewing. You might find fitting your socket to an impact wrench (even a manual one you use with a hammer like this http://wiki.diyfaq.org.uk/index.php?*** ... act_driver ) might help to loosen it. Hold the pulley with a strap wrench or similar.

Thanks for the response, i cannot see any tab washer. Left hand threads you turn counter clockwise (left) to tighten ?? Is that correct
