What This Product Does

The shell forms the renewable bearing interface between a crankshaft journal and the connecting rod’s big end. With the correct measured clearance and lubrication, this interface accommodates rotation without direct contact between the rod and journal.

Functions

• Provide a replaceable journal-facing bearing surface.
• Support lubricated movement at the rod’s big end.
• Establish running clearance when correctly selected and installed.

Technical Details

• Manufacturer: Porsche; reference 94810323027.
• Yellow identification marking; lower position explicitly recorded for the applicable Macan and Panamera 3.0L diagram rows.
• Macan row codes: CTMA, CTM, DCNA, DCN; assembly quantity recorded as 6.
• Cayenne 4.8L row code: 4802; assembly quantity recorded as 16.
• Panamera 4.8L row codes: 4820, 4840, CXPA, CXRA, CXR; assembly quantity recorded as 16.
• Panamera 3.6L assembly quantity: 12; Panamera 3.0L assembly quantity: 6. These diagram quantities do not indicate pack contents.

Symptoms of Fault

• Big-end knocking that becomes more noticeable with rising revs or load.
• Reduced oil pressure after the engine reaches operating temperature.
• Metal fragments discovered during lubricant or filter inspection.
• Measured running clearance outside the engine specification.
• Scratched surfaces, overheating marks or other bearing damage.
• Inspection evidence of lubrication loss or shell rotation within the rod.

Why Replacement Matters

Bearing wear may increase clearance and affect journal lubrication, with further deterioration potentially damaging adjacent engine components. During rebuilding, assess the crankshaft, rod big-end dimensions, lubrication passages and fixing requirements before installation. Select the shell using engine-specific identification and clearance measurements; the yellow marking alone is not sufficient to establish suitability.

FAQs

Where is this shell installed?
The relevant Macan and Panamera 3.0L rows identify the lower position. Verify both location and identification marking against the particular engine assembly.

How many shells does the job require?
The supplied diagrams record assembly quantities of 6, 12 and 16, depending on application. Establish the required count from the engine being repaired; these figures are not a supplied-set specification.

What else needs checking during renewal?
Inspect journal condition, rod dimensions, lubricant passages and fasteners. Confirm the required bearing clearance before completing assembly.
