4.3.2. Injection pump
The components related to the injection pump should be serviced at regular intervals as the
plunger and delivery valve may be worn after a given length of time for use and cause the dete-
rioration of the engine.
Make sure that servicing should be performed at the professional maintenance shop as autho-
rized by Bosch or Zexel Company.
For adjustment of fuel injection volume, refer to the 'Specifications of fuel injection pump'
described on the following pages.
