The engine used in all 1942
passenger cars and trucks is a
six-cylinder, valve-in-head type. The regular production engine for passenger
cars and all trucks has a displacement of 216.5 cubic inches, using a 3-1/2" bore and 3-3/4" stroke. For
1-1/2-ton trucks only a heavy
duty optional engine is available. This engine has a
displacement of 235.5 cubic inches
using a 3-9/16" bore and 3-15/16" stroke.
All parts of the two engines are
interchangeable with exception of the
following parts. Cylinder block and Crankcase, crankshaft,
camshaft, pistons and pins, all piston rings, oil pump screen cover support, oil pan pipe assembly, oil pan,
oil distributor to valve
rocker shaft pipe, valve lifters and push rods.
Service operations on the two
engines are performed in exactly the same manner, and all checks
and clearances, with exception of the
connecting rod oiling system, are the same on the two engines.
The only additional tool required on
the heavy duty engine is the
J-1646 oil trough depth and connecting rod dipper height
