What This Product Does
These bearing shells sit between the connecting-rod big ends and crankshaft journals. With the correct clearance and oil supply, they provide a lubricated interface that accommodates rotation and transfers combustion loads through the connecting rods.
Functions
- Provide the bearing interface at the connecting-rod big ends.
- Maintain space for the lubricating oil film when correctly matched and installed.
- Distribute loads across the crankshaft journal bearing surfaces.
Technical Details
- Supplied part reference: 61610314272.
- Bearing specification: 0.75mm inner undersize.
- Product type: big end connecting-rod bearing set.
Symptoms of Fault
Possible signs of bearing wear include a knock or rumble under load, reduced oil pressure when hot, and metal particles found during oil or filter inspection. Scoring on removed shells also warrants investigation. These findings are not exclusive to con rod bearings, so establish the cause before selecting replacement parts.
Why Replacement Matters
Renewing worn shells forms part of restoring the specified bearing clearance during engine repair. Inspect the crankshaft journals and connecting rods, measure the assembled clearance, and investigate lubrication problems or contamination before reassembly. New bearings alone will not correct damaged journals or an unresolved oil-supply fault.
FAQs
Can I choose these bearings by vehicle model alone?
No. The 0.75mm inner undersize must also match the crankshaft's measured condition and machining specification.
What can cause premature bearing wear?
Insufficient lubrication, contaminated oil, overheating and incorrect assembly clearances can contribute.
What should be checked during replacement?
Inspect journal surfaces, measure bearing clearances and identify any debris or oil-system fault responsible for the original wear.

LIQUI MOLY LM 48 Spray Paste – 300ml
LIQUI MOLY LM 48 Spray Paste is a heavy-duty assembly and maintenance lubricant designed to reduce friction, prevent wear and protect metal components against corrosion.
Its molybdenum disulphide-based formulation provides excellent adhesion, even on smooth surfaces, making it particularly useful when assembling bearings, bushes, pins and sliding components.
What Does It Do?
LM 48 Spray Paste forms a strongly adhering lubricating film on metal surfaces, helping prevent direct metal-to-metal contact.
It is particularly useful for protecting components during assembly and initial operation, reducing the risk of scoring, seizing and premature wear.
Why Is It Important?
Bearings, bushes, pins and sliding components can experience high pressure and friction during installation and operation.
Insufficient lubrication may cause:
- Metal-to-metal contact Scoring and surface damage
- Seized components Increased mechanical wear
- Corrosion during service
LM 48 provides a protective lubricating layer to help minimise these problems.
When Should It Be Used?
Use during the assembly, repair or maintenance of suitable
metal components, particularly:
- Bearing and bush installation
- Press-fitting pins and bearing bushes
- Assembly of plain bearing rings
- Lubrication of sliding guides
- Basic lubrication of joints and small mechanical components
Do not apply to brake friction surfaces, belts or components requiring a specified alternative lubricant.
Application Instructions
- Clean the surfaces before application.
- Shake the aerosol thoroughly.
- Spray a thin, even coating onto the required surfaces.
- Avoid excessive application.
- After use, invert the can and spray briefly to clear the nozzle.
Key Features
- Contains molybdenum disulphide, graphite and other solid lubricants
- Excellent adhesion to metal surfaces
- Reduces friction and mechanical wear
- Helps prevent scoring and seizing
- Provides corrosion protection
- Suitable for heavy-duty assembly applications
- Emergency-running lubrication properties
- Operating temperature range -35°C to +450°C
LIQUI MOLY Assembly Lubricants & Maintenance Sprays for Porsche
Correct lubrication during component assembly helps prevent premature wear, corrosion and damage to precision metal surfaces.
LIQUI MOLY LM 48 Spray Paste is suitable for a wide range of appropriate Porsche workshop applications, including bearing installation, suspension component assembly and lubrication of metal sliding surfaces.
Its high-pressure lubricating properties make it particularly useful during classic Porsche restoration and routine mechanical maintenance.
