REPAIR INJECTION PUMP ANEROID--IF
EQUIPPED
For aneroid repair and adjustment, have an authorized
diesel repair station perform the work.
The aneroid controls fuel delivery to pump when intake
manifold pressure is about 100 kPa (1.00 bar) (15 psi) or
less. Therefore, all final adjustments are to be made on
the test stand with aneroid mounted on injection pump.
IMPORTANT: Correct aneroid adjustments are
essential for satisfactory engine
performance. Whenever aneroid has
been disassembled or adjustments have
been altered, injection pump (including
aneroid) must be calibrated on test
stand before releasing pump for
service.
