VALVE-CHECK 2339821 - Caterpillar

The level of maintenance an engine receives is crucial to the life of crankshaft bearings. Other major factors affecting crankshaft bearing life are operating rpm and bearing loads.Since the levels of maintenance and operating conditions experienced by the wide spectrum of owners is so varied, our recommendations for the 3406B crankshaft bearing maintenance are as follows:Connecting Rod Bearing Inspection And Replacement
* Engines should be inspected between 250,000 and 300,000 miles (400 000 and 480 000 km). See the Maintenance Management Schedule for your engine. This inspection consists of removing connecting rod bearings only and inspecting them for any sign of dirt and debris having been passed from the main bearings.* If connecting rod bearings do not show any of these signs, Caterpillar recommends that the main bearings be left alone and only connecting rod bearings be replaced.Caterpillar believes that crankshaft bearing maintenance as outlined above, and offered by many dealers, is relatively inexpensive and a good value. In addition, the new connecting rod bearings have a one year parts warranty. See the Maintenance Management Schedules in this publication for the proper intervals of the specific power rating for your engine.
