Ponsell Floor Machine


Hello all. I'm helping a friend with a Ponsell Floor Machine. It has a 1/2 hp motor with about 1700 rpms. I took the top cap off where the gears are located and the black arrow is pointing. I don't know how much oil goes back in but there is none in there exposing the gears. What type of oil goes in there? Thanks in advance.



most old gear boxes use 80-wt mineral oil or sometimes 40 wt but like the last guy said oil is better than no oil, (grease is cheaper than steal)….:D
