Compression pressure
4. Connect compression tester. Turn engine with starter.
Compression pressure:
F engine 25-30 bar
BF engine 22-27 bar
The measured compression pressure is dependent on the
starting speed dur-ing the measuring process and also on
the altitude of the engine site.
Therefore it is difficult to specify precise limit values. It is
recommended to use the compression pressure measure-
ment only for comparison of compression pressures of all
cylinders in one engine. If a difference in pressure in
excess of 15 % is determined, the cylinder unit concerned
should be dismantled to establish the cause.
Note: Fit injector with new special seal
and tighten.
Tightening specification: 21 Nm
Tighten injection lines.
Tightening specification: 22 + 2 Nm
The leakage fuel line must always be renewed.
