GENERAL
These instructions are written for worldwide use. In territories
where legal requirements govern engine smoke emissions,
noise, safety factors, etc., then all instructions, data and
dimensions given must be applied in such a way that, after
maintaining or repairing the engine, it does not contravene
regulations when in use.
NOTE: These instructions cover only the routine
maintenance of the engine. Refer to the engine
manual furnished with the crane for engine
diagnosis, repair and component replacement.
ENGINE TYPE
The engine is a Cummins QSB3.3 Tier 4i diesel.
ENGINE PERFORMANCE
Engine performance is very important to the operation of the
crane, the engine is the drive for the hydraulic pump, which
supplies power to operate the work functions of the crane.
For maximum power the engine must be kept in good
working condition.
ENGINE RPM
To check the engine speed, follow the instructions in the
engine operator’s manual. Maximum and minimum speeds
are controlled by the engine Electronic Control Module
(ECM). The throttle gives variable control of the engine
speed.
ENGINE CRANKCASE SYSTEM
The engine crankcase system must be well lubricated to
inhibit damage to the engine. The correct type of oil must be
used, as well as proper maintenance at regular intervals. For
correct intervals, see SECTION 5.
Crankcase Oil Data
Use oil viscosity based upon the expected air temperature
range during the period between oil changes.
Oil Performance Recommendations
CF-4, CH-4, CI-4, or CJ-4 for use in naturally aspirated
engines and in engines that operate in light duty service
including standby and emergency operation (equivalent to
MIL-L-2104B).
Sulfated Ash Limit of 1.0% by weight is recommended. Oils
with higher ash count may produce deposits on valves that
can progress to guttering and valve burning.
