Diagram ref no 29.
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.

NOTE: For the 2001 model year, Porsche replaced the intermediate shaft's roller-type (duplex) chain with a tooth-type chain. This listing is for the later tooth-type chain and is not compatible with earlier engines equipped with the roller-type chain.
While unlikely, it's possible that an earlier engine may have been rebuilt and upgraded to use the newer chain design. For this reason, Design 911 strongly recommends confirming which type of chain your engine uses before placing an order. To assist with identification, our product images include a helpful comparison between the roller-type (duplex) chain and the tooth-type chain.

OEMatch Intermediate Shaft — Fit, Function, Confidence
OEMatch provides intermediate shaft parts and bearing kits for Porsche models, aimed at restoring timing integrity and supporting engine rebuilds or preventive maintenance. Parts and kits are selected to address known weak points in certain flat-six engines while maintaining compatibility with factory mounting points and lubrication paths.
Understanding OEMatch Intermediate Shaft
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original intermediate shaft.
OE (Original Equipment) refers to parts matching original specifications for the intermediate shaft and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM intermediate shaft engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The intermediate shaft links crank and cam timing on Porsche flat-six engines; it supports bearings and transmits rotation to maintain valve timing, balance and smooth power delivery. Wear or bearing damage can upset timing and lead to secondary engine damage.
Benefits Include
- Restored camshaft-to-crankshaft synchronization for consistent combustion and idling.
- Improved bearing durability through upgraded materials and clearer oiling paths.
- Reduced risk of debris circulation by replacing worn bearings and seals.
Why Intermediate Shaft Wear and Fail
- Bearing degradation caused by age, contamination or oil breakdown.
- Insufficient lubrication or oil-passage blockages leading to overheating.
- Metal fatigue and material weakness in earlier bearing designs.
The Importance of Replacing with OEMatch Intermediate Shaft
Addressing intermediate shaft wear promptly reduces the chance of catastrophic engine damage and limits secondary repairs. Replacing the shaft or bearing assembly during a rebuild or at the first sign of distress restores correct timing and helps maintain the characteristic balance of Porsche flat-six engines. Choosing appropriately specified parts simplifies installation and reduces the need for additional remedial work.
Advantages
- Parts selected for Porsche applications and engineered to original-spec dimensions where applicable.
- Options suitable for rebuilds, preventive maintenance or performance-oriented projects.
- Detailed product descriptions and part references to aid correct selection.
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. If you are uncertain about hidden sensors, oiling passages or alignment procedures, seek professional installation to avoid engine damage.
