I recently bought a rockwell horizontal mill.
The back gears for the spindle are totally enclosed in a very tall cavity. The manual says to use grease (7oz). It appears there is a drain plug on the back of the machine (above the motor) and a fill plug on the side of the machine which is probably about 1 inch from the bottom.
Based on my previous experience with rockwell machines, I suspect the recommended lub is no longer made. What kind of grease should I use and how to I purge the old grease.
As a side note. The back gears run ok, but there is some noise which is typically of backlash in gears. I have no idea if the amount of noise is typical or excessive.
Anyone out there with a rockwell horizontial that can provide some advice????
