I am renovating a Pultra 1770 lathe and Mardrive bench drive unit.

The oil cups need replacing.
The third pulley (lower one that drives the final pulley that drives the lathe) has been removed and replaced without the key and nut, I have found the key and nut in the assortment of bits that came with it.

Could anybody help withe following information.
What thread is used for the oil cups on the lathe and Mardrive?
Is any thing else required to fit the pulley?
Thanks
Ken
