Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I picked up an old Bolens 726 off Ebay last summer.     The engine is a Tecumseh H70 made in 1976.   The blower was in pretty good shape- still had factory paint on the augers. [the shoes had never touched the ground, though- so the bottom of the scoop took some abuse and needed a bit of welding]

I've been tinkering long enough and finally have it almost ready for work.   The differential has me puzzled, though.    It has two little tubes, maybe 1/8-3/16" outside diameter, coming up from either end of the axle.   There are screws plugging the ends.     I'm guessing they are there to add/check fluid levels, but I don't know how much of what fluid to put there. [if any]

The differential has a big cast iron 'wing nut' on the right hand wheel.  I can take photos if necessary.

Thanks,

Jim

Are there any gaskets on the screws?

Boy am I redfaced.   I just went out to the garage to take some pics of these little 'pipes'.      While trying to get a good shot of where they terminate, I realized they are for lubing the axle bushings!   They don't go to the sealed differential.

Thanks for making me take a second [10th?] look at them.

Now I'm wondering if those screws replaced zircs, or are the pipes an add-on by a previous owner to make oil holes more accessible.

The pipes suggest oil- but my gut says grease would be more appropriate for brass bushing on the axle.

Thanks,

Jim
