Information
SET OF 12 connecting rod bearing shells - standard size.
This bearing set directly replaces the factory standard-size bearings and includes all shells required for one engine rebuild. These bearings provide smooth, low-friction rotation between the connecting rod and crankshaft journal, maintaining the correct oil film clearance critical to engine reliability and longevity.
Fits:
Porsche 911 T-E 2.4L (US/Canadian Market - Mechanical Fuel Injection) 1972-1973

Diagram Ref. 23.
• Position: Connecting rod big-end journals
• Function: Maintains oil film clearance and crankshaft rotation stability
• Symptoms of Failure: Low oil pressure, engine knock, metal debris in oil
• Replacement Interval: During rebuild or low oil pressure diagnosis
• Benefits: OEM fit, stable lubrication, high load resistance, quiet operation
• Set Contents: Complete set for one engine (6 cylinders)
Rod bearings gradually wear due to high-speed loading, heat, and oil contamination.
Excessive clearance or bearing wear can lead to:
• Low oil pressure Metallic noise or “rod knock”
• Engine vibration or bearing seizure
Replace bearings:
• During every engine rebuild or crankshaft regrind
• If metal particles are found in oil
• When oil pressure is below specification or knocking occurs
Installing a new bearing set restores correct oil clearance, stable pressure, and long-term bottom-end reliability.
