In this way specified oil clearance could be maintained.
The bearing was adjustable for wear by removing copper shims placed between the rod cap and connecting rod. Rod bearings were made of babbitt cast integral with the rod. The connecting rods were oiled using an "oil trough" built into the oil pan that had spray nozzles that squirted a stream of oil at the connecting rods (which were equipped with "dippers"), thus supplying oil to the rod bearings. This generation did not use a fully pressurized oiling system. A new cylinder head in 1941 increased output to 90 hp (67 kW), and 6.6:1 compression gave the 1949 model 92 hp (69 kW).
A four-bearing crankshaft was added, along with 6.5:1 compression pistons, for 85 hp (63 kW). This engine had a 216.48-cubic-inch (3.5 L) displacement with a bore and stroke of 3.5 by 3.75 inches (88.90 mm × 95.25 mm).
