Re: 1947 Hiawatha 3hp
There should be a large screw on one side of the gearcase (grease fill) and a small one on the other side (vent). There probably is a third one, water flush. It uses grease for gear lube. The seals are not good enough to hold oil. Most people use Lubriplate 105 "Motor Assembly Grease" from NAPA Auto Parts Stores. Others use "Corn Head Grease" from John Deere farm equipment dealers. The Lubriplate comes in a squeeze tube, corn head doesn't.
Daymon, your motor is a 5hp.
That is awesome. I'm so glad you told me that. I would have loaded it up with 80W gear oil otherwise. I'll go to our local John Deere dealer and grab some of that grease. I was wondering how in the world I was going to get the lower unit filled without a "bleed" cap at the top of it.
There is a screw on the right side (looking at the engine from the back) that looks large enough to fit a small grease hose in, and there is a really small screw on the left side of the unit, but it is super small.
Do you happen to know the "
year" on mine as well? The person I bought it from said it was from the 40's but it doesn't look quite that old. Couldn't find a plate on it anywhere that would indicate a year/make/model.
They haven't started it in 45 years. I pulled lightly on the starter rope and it isn't locked up thankfully.
Thanks again for your input and information regarding this motor.
