Inspection
Inspection of big-end bearings is required whenever
removing pistons. If the wear pattern is unsatisfacto-
ry of if deep scoring and/or embedments of foreign
particles are discovered.
Inspect one main bearing also, in accordance with
the Maintenance Schedule, and, if in bad shape, the
rest als. The first bearing to be inspected should be
the central one.
Big-end bearings and main bearings which have
already been running for
20 000 hours with distillate fuel,
18 000 hours with mixed oil or heavy oil 1 and
15 000 hours with heavy oil 2
must be renewed, even if they are still of good appearance, since they are likely to have lost their running-in
properties due to advanced wear and tear at this stage.
Renewal of all big-end bearings and main bearings is due at the end of about 40.000 running hours.
Bearings to be refitted must be inspected with regard to:
● adequate spread (Job Card 02.03.02),
● correct running clearance (Job Card 02.03.03),
● wear pattern.
Depending on the number of running and operating conditions, the wear patterns of bearing shells may differ
widely. In all cases of doubt, therefore, it will be advisable to consult a DEUTZ serviceman.
