DM1114, if you would to take a look at the gearbox side facing the tailstock, you can see that the side is a 1.25" thick cast iron plate with two oiling ports. Now this plate is held in with three socket heads. Remove these socket heads and the plate will come off. What you should see are THREE, NOT TWO, oiling ports. One hole is circular and the other two is oval shaped. For the life of me, I could not figure out the necessity of having that cast iron plate in place; in my opinion it's becoming vestige. I could not find that cast iron part called out in all versions of Grizzly G4002, G4003, and G4003G manuals.
Now, with that plate off, the top oiling port goes directly into the top portion of the gearbox. The top portion performs as a shallow oiling pan/reservoir. The bottom of the pan has two or three additional holes situated above the gear assembly where it should be lubed. So the top oiling port needs to be squirted with oil generously. The other two oiling ports (oval shaped) go directly to some shaft bearings that need to be lubed.
Hope this helps.
I want to make sure I understand your post. Are you saying you take the endplate off every time you oil your transmission rather than using the two factory supplied oiling ports?
