cafoose 3,153 #1 Posted December 12, 2017 Where do I check the gear oil in the gearbox on my Ber-vac snow thrower? I have the manuals from the files and they only show the parts diagrams Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,509 #2 Posted December 13, 2017 #13 should be a 3/8" pipe bushing with a 1/8" pipe thread vent #14 in it. 3/8" pipe has an OD of .675" so you have a hole almost 5/8" in diameter. If the oil is half way up the upper shaft it should be good. That way you know the bearing and bushing on that shaft are getting lubed and still leaves room for expansion.
