02-14069-000 Pilot Bearing Spacer for Diesel Engines
Issue Description: Reduced transmission input shaft support caused by insufficient engagement of the pilot bearing on Detroit Diesel engines. Reduced input shaft pilot support can cause the following symptoms and failures. ? Oil leak at transmission front bearing cover. ? Transmission main drive gear and input shaft damage. ? Difficult to get transmission into a start gear. ? Clutch noise and vibration. ? Clutch release bearing, driven disc, and pressure plate damage Field Containment: Detroit Diesel has released a spacer to properly place the pilot bearing in the engine flywheel. Installation / Inspection Process: ? Install spacer 02-14069-000 between the flywheel and a new pilot bearing when the transmission is removed for service work. ? Inspect the transmission input shaft pilot surface and oil return threads (see picture below). Replace the input shaft if there is evidence of any wear at these locations or the transmission was leaking oil at the front bearing cover before it was removed. ? Replace the transmission front bearing cover if the input shaft oil return threads are damaged. ? Remove shift bar housing and inspect the main drive gear set for tooth damage before placing the transmission back in the vehicle. Replace any damaged gearing
