Note:
All parts of the injection pump are manufactured with utmost precision in special
workshops. This is the only guarantee for proper function. When repairing a pump, it is
to be ensured that the various components of the pump, e.g. control sleeve, control rack,
rack pointer etc. remain together with their respective housing.
Plunger and barrel must be renewed as a unit only. In order to keep repair costs low,
any parts to be reconditioned should be shipped only complete, and the possibility of
interchanging must be excluded. Lapped surfaces must be preserved and not touched
with fingers.
