Bearing Technician's Guide from Detroit Company
كورس جامد جدا عن الــ Bearing
1 INTRODUCTION
The purpose of this guide is to illustrate variations of crankshaft main bearing and connecting
rod bearing wear after use in an engine. Bearings removed from an engine can be compared to
photographs in this guide to determine the cause of the bearing condition and old bearing usability.
The service life of the bearings are expected to be the same as the overhaul life of the engine under
normal operating conditions and recommend maintenance practices.
1.1 MAINTENANCE
An effective preventative maintenance program for the engine and its supporting systems will
maximize the engine bearing life. Preventative maintenance starts with a daily inspection
of the engine by the operator for correct fluid levels and replenishment of any low fluids,
refer to section 6. Periodic maintenance inspection of the engines air inlet, cooling, fuel, and
exhaust systems must be scheduled as each of the related systems can affect engine bearing
life. This periodic inspection schedule is available in the appropriate Detroit Diesel
engine
service manual.
Maximum bearing life, as well as long engine life, will depend upon an established maintenance
program that is followed on a regular basis.
The major cause of bearing damage is dirt and foreign particles which can come from careless
handling, poor cleanliness, and failure to follow a maintenance program.
Ensure the engine oil used in the engine meets Detroit Diesel lubricating oil requirements. The
requirements for proper lubricating oil are based on SAE Viscosity Grade and API Service
Designation. The requirements are covered in Detroit Diesel Lubricating Oil, Fuel and Filters
bulletin, 7SE270.
Filters make up integral part of fuel and lubricating systems. Proper filter selection and
maintenance are important to satisfactory engine operation and service life. Filters, however,
should be used to maintain a clean system, not to clean up a contaminated one. Filter performance
and test specifications very between manufacturers. The filters recommended by Detroit Diesel
have been qualified to appropriate SAE performance specifications and meet manufacturer’s
requirements. Refer to Specifications for Detroit Diesel Maintenance Products in Detroit Diesel
Lubricating Oil, Fuel and Filters bulletin, 7SE270. Other brands may be used, provided they
have demonstrated equivalent performance.
