Saab 96 - Engine, Sectioned

Fig. 4. Engine, sectioned
Lubrication is obtained by adding oil to the gasoline, when refueling.
The cylinder block is integral with the upper part of the crankcase
and is machined in pair with the lower crankcase half. These two parts
are iron castings while cylinder head and pistons are of aluminum
alloy.
The crankshaft is supported in the crankcase by four single-row
ball bearings, and the big-end bearings of the piston rods are double-
row roller bearings. Since the crankshaft is built-up of disks, intercon
nected by main and big-end bearing pins with very close tolerances
requiring special precision tools, it should be reconditioned only by
the manufacturer.
The engine and the transmission are bolted together and constitute
the power unit, which is supported on three rubber cushions. The
engine can be lifted out very easily either separately or together with
the transmission.
