Noma / Murray Snowblower
I recently acquired a Noma snowblower model 627104X8. This is a 27" cut with a 10hp Tecumseh - vintage 1998. Naturally it did not come with a user's manual nor can I find one on the internet.
I am in the process of refurbing it. I would like to drain and replace the auger gearbox lubricant; however I can not find what type is used on this model. I see references to 00 grease, 80-90 SAE gear lube, synthetic oil and SAE 30. Does anyone know what was used originally. To me, it appears to be SAE 30. I'm leery of using anything other than what it was designed for.
Any help will be appreciated. Particularly the lube type and any specific procedures to use. Also any lead to a user's manual.
