Flywheel Forum


| January 2005

I have a nice, quite common, McCormick-Deering IHC 1-1/2 HP farm engine (#AW29626) that is missing the drip oiler, and I have a nice replacement one that can be threaded onto the vertical pipe that goes through the water hopper to the cylinder. It has the needle valve and glass tube window below for setting the drip rate. My question is: Does this engine require any kind of check valve between the oiler and the pipe leading down to the cylinder to prevent pressure from blowing back through the oiler? This engine has an enclosed crankcase, and I can imagine pressure in there would interfere with the oil drip flow. What oiler should this engine have?

This engine runs nicely and the governor-controlled throttle makes it chug delightfully when under load. The engine is in great original shape and is on the original iron-wheeled cart, which has a nice laminated maple mounting deck.

I also have a 30-year-old, good-sized Massey Ferguson lawn tractor powered by a 12 HP Kohler that I no longer need. The mower deck has been off for years and the tractor would not bring much if sold. I am thinking of mounting the McCormick-Deering engine in place of the Kohler to make a drivable vehicle. The power path to the transmission looks quite feasible by pulling a flywheel and adding a pulley or sprocket. If possible, rotation would be reversed with gears somewhere so that the engine can be mounted with the cylinder facing forward.

Ignoring the cost and work involved, is it wise to cannibalize this original, pristine, cart-mounted engine for this project? The engine is ideal, the governor throttle better than hit-and-miss, and the enclosed crankcase will not throw oil back on the driver. Opinions are requested.
