I'm trying to get a Rockwell Horizontal milling machine back in service. It's missing a couple of pieces and I hope I can get some measurements.
First up is the missing oil cup for the spindle. The real issue is that I want to make sure I have the right oil level for the spindle bearings. For those with original oil cups, how tall is the cup and where is the top relative to the spindle? Gits has some threaded cups that are 35.7mm (roughly 1-7/16"), 40.5mm (1-9/16"), and 52.4 mm (~2") tall. I could also use a street elbow (what I used to flush it), but still need the height.
Next is the missing motor pulley. I "reverse engineered" the step sizes using the published RPMs and the countershaft pulley sizes, and also tried to get the belt length to be the same for each position. I came up with a pretty good match, shown below. For those of you with a horizontal, do these seem right to you? How do they compare with the stock motor pulley?
Code: Select all
RPM Motor Pulley
374 2-3/8"
855 4-1/4""
1522 5-5/8"
1855 6-0/0"
2345 6-1/2"
Thanks for your help!

P.S. I posted over at the yahoo group last week but didn't yet get the response I hoped for.
