17C ENGINE TIMING
General description
The timing gears are stamped with timing marks to
ensure that they are assembled correctly (A). The
stamped teeth of the crankshaft, camshaft and fuel
pump gears will be in mesh with the idler gear
when number 1 piston is at top dead centre (TDC)
on the compression stroke. The marked teeth of
the idler gear may not necessarily be in mesh in
this position, because of the different speeds at
which the gears rotate.The fuel pump gear has
timing marks for four and six cylinder engines. Also
the gear is stamped with the letter "C" where a
Lucas fuel pump is fitted. The letter "M" is stamped
on the fuel pump gear to indicate that the threads
for the screws of the gear puller are metric.
A data plate is fitted to the side of the pump. An
example of the information shown on the plate (B)
is:
Manufacturers model number (1)
Manufacturers description number (2)
Maximum engine no load speed (3)
Fuel pump code letters (4)
Perkins part number (5)
Fuel pump serial number (6)
For details of the fuel pump code letters for the
engine see the data and dimensions at the end of
this section.
