pump drive rod
To check the drive rod it is necessary to
disassemble the fuel pump.
See “Disassembling the fuel pump” for the
correct procedure.
1 - Rotate the camshaft until the drive rod is
at the most indented point.
2 - Check that the distance between the drive
rod (A) and the cylinder head is between
1.66 and 2.18mm. If the distance does not
correspond to this value, replace the drive
rod with an original spare.
3 - Assemble the fuel pump (see “Assembling
the fuel pump”).
