Question 1978 Bob-Cat Snow Thrower

My Bob-Cat's the oldie, made by Wisconsin Marine, Lake Mills, WI, not the Bobcat skid steer folks. It's a 5 HP, 20" model.

The operating instructions say, "...remove engine plate and apply Lubriplate Marine A to chains in transmission. Add Lubriplate No. 2 to felt bearing feeders."

Hoping someone's familiar with these old workhorses and can tell me what/where the engine plate and bearing feeders are. Drawings/sketches/pics would be really helpful.

Thanks.

Welcome to the forum. Does your machine look like the one in this thread?

Similar, but not exactly. Mine has a B & S engine, not Tecumseh, and belt guard is orange like rest of machine, not black. I also have no headlight.

The Tecumseh engine on sj701's Bobcat is clearly not the original engine..
that engine is much newer than the snowblower..his likely originally had a Briggs as well..

If yours is a 2-speed forward and reverse, the insides look like this. The motor plate is the plate that the motor is bolted to, so no easy access. The felt bearing feeders can be seen in the dismantled photo. There are also oil cups on the outer ends of the shafts and the auger.

Thanks for the really helpful pics. I was afraid the motor plate was as you described, definitely not easy access. How important do you think it is to do this?

I assume the felt bearing feeders are the disc-shaped, felt-appearing items in your pic. Do they "feed" lube to the bearings?

Yes, they hold oil and gradually "feed" it to the porous bronze iolite bushings.
The manual says;
"Every 100 hours or 4 years remove engine and engine mounting plate and apply Texaco All-Temp Grease or similar grade to chains in transmission. Saturate 3 felt bearing feeders (37) with motor oil (5W-30)."
