ALL VIEWS FROM REAR (FLYWHEEL) END OF ENGINE

On the in-line engines, the model # & serial # are stamped on the right-hand side of the cylinder block in the upper rear corner.

An example of a Series 4-53 serial # is 04DXXXXXXX. Engines built in Brazil have a serial # prefix of 3DB (three cylinder), & 4DB (four cylinder). The engine serial # is required when placing a parts order.

Model # 5043-5100 is interpreted as follows: Series 53 Engine (5), four cylinder (04), industrial, fan to flywheel (3), right-hand rotation with "A" accessory arrangement (5), two-valve head engine (1), & specific model # 00 (00).
