These high-quality bearings resist wear, maintain stability under loading, and reduce friction. The shoulder shell is designed to handle axial load and keep the shaft from shifting. Both shells are matched to OE tolerances for crush and thickness to preserve ideal oil film clearance and ensure long life.
• Location: Inside the engine case, at the intermediate shaft bore, flanking the connecting housing
• Function: Provides radial support and axial control (shoulder shell) for the intermediate shaft
Over time, the intermediate shaft bearing shells may wear, lose geometry, or develop surface fatigue. Symptoms of failure include increased endplay (shaft axial movement), chain rattle, timing variation, and rapid wear of adjacent sprockets or tensioners.
This pair should be replaced during any engine rebuild, crankshaft pull, or when measurements show endplay outside specification. Installing fresh shells restores proper shaft location and timing stability for durable performance.

Main bearing set Standard Size.
Set includes: 24 x Bearing shells / 2 x End shells
The Main Bearing Set is a replacement for the original Porsche crankshaft main bearings used in 911 and 914 engines. These standard-size bearings are manufactured to exact OEM tolerances, providing a perfect fit, proper crush, and ideal oil clearance for stable lubrication and crankshaft alignment. The set includes all main bearing shells required for a complete rebuild of one engine, providing smooth, quiet rotation and factory-spec oil pressure.

- 901 101 132 02 - Bearing shell x12
Main bearings wear over time due to heat, load, and oil pressure fluctuations. Worn bearings can cause low oil pressure, crankshaft vibration, or bearing noise.
Replace these bearings:
• During a full engine rebuild or bottom-end overhaul
• When oil pressure drops or metal particles appear in the oil
• As part of preventative maintenance on high-mileage or vintage engines
New bearings restore precise crankshaft support, improve lubrication stability, and extend engine life.

• When oil pressure drops or metal particles appear in the oil
• As part of preventative maintenance on high-mileage or vintage engines
New bearings restore precise crankshaft support, improve lubrication stability, and extend engine life.

About Engine Bearings / Shells
OEMatch Engine Bearings / Shells — Durability, Sealing, Performance
OEMatch engine bearings / shells for Porsche models are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Shell bearings support crankshaft and connecting rod rotation, maintain oil clearance and distribute combustion loads to protect internal components.
Available Types- Big end (connecting rod) bearings
- Thrust bearings
- Main and journal bearing shells
Understanding OEMatch Engine Bearings / Shells
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine bearings / shells.
OE (Original Equipment) refers to parts matching original specifications for the engine bearings / shells and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine bearings / shells engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.

Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine bearings / shells engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide selection of Porsche parts, including engine items, and maintains thousands of part numbers and cross-references to support rebuilds and restorations.
- Restores correct oil clearance and lubrication
- Reduces knocking and vibration from worn journals
- Prevents crankshaft scoring and internal wear
- Oil starvation or sustained low oil pressure
- Contaminated or degraded engine oil introducing abrasive particles
- Incorrect clearance, poor installation or worn mating journals
The Importance of Replacing with OEMatch Engine Bearings / Shells
Replacing worn shell bearings during an engine rebuild or repair protects the crankshaft and block from scoring, restores reliable oil pressure and film strength, and supports consistent operation across varying loads and temperatures in Porsche engines. Timely replacement reduces the risk of secondary damage and helps preserve engine life.
Advantages
- Tri‑metal and bi‑metal alloy options for thermal stability
- Precision-machined tolerances to maintain oil film and clearance
- Suitable for a wide range of air-cooled and water-cooled Porsche engines
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
