1.3.2 Pump Options/Identification
The Century Pump is available in either 4 or 8 cylinder options, with each having a choice
of piston/cylinder diameter options of 22.5 mm, 25.0 mm or 27.5 mm.
All barrels are given a letter code to indicate their position in the crankcase (refer to
Section 4, Fig 4.2). This letter code can be found stamped on the face adjacent the inner
cylinder. Letters A to H are used. Each barrel of a different code is given its own part
number.
A pump specification label is fitted on the pump crankcase, adjacent to the oil filler cap.
This label will give the pump type, ie number of cylinders and piston/cylinder diameter.
For example:
8 22.5
no. of cyl piston dia.
The label also gives the pump serial number, the type of oil to be used (Shell Tellus or
equivalent), the maximum working pressure, the maximum working flow, and the pump's
year of manufacture.
