Daytona Shelby Z L4-135 2.2L SOHC Turbo VIN E FI (1988)
Balance Shaft: Description and Operation
The 4-135 engine is equipped with two balance shafts installed in a carrier attached to the lower crankcase.
The shafts are interconnected through gears to rotate in opposite directions. These gears are driven by a short chain from the crankshaft, to rotate at two
times crankshaft speed. This counterbalances certain engine reciprocating masses.
