The flywheel is bolted to a flangeforged solid with the crank shaft andis easily removable if required wheninstalling. Plunger pumps are used on the slowand medium speed motors for watercirculation and gear pumps on motorsbuilt for high-speed. All water fittingsbeing of brass or bronze every motor issuitable for salt water use without anyalteration. The chrome nickel steel valves areprovided with ample cooling arrange-ments and are so designed that theycannot drop into the cylinder should theretaining pin become broken. The cam.

Ample waterspace is provided, with a plug for clean-ing out the jacket. The valves being inthe cylinder head, side pockets are doneaway with, and the whole charge to beignited is directly over the piston, in-suring perfect combustion and givinggood economy in operation. The base is made in two pieces, theupper one being well ribbed throughoutto support the cylinders and crank shaftbearings. The supporting of the crankshaft bearings in the upper base castingprovides a unique adjustment for wearin that the shaft is raised to its originalposition and is not being graduallylowered as the bearings wear. Largeplates are provided on the side of thecase for the easy removal or adjust-ment of the co
