Diagram Ref No 1
The bearing provides a low-friction surface between the connecting rod and crankshaft journal, helping maintain correct oil clearance and protect internal engine components.
What Does It Do?
The big end bearing supports the connecting rod on the crankshaft journal, allowing smooth rotation while maintaining a protective film of engine oil between moving surfaces.
Why Does It Fail?
Common causes include:
- Insufficient oil pressure or lubrication
- Contaminated engine oil
- Excessive engine wear
- Incorrect bearing clearance
- Engine overheating
When Should It Be Replaced?
Replace during an engine rebuild when the existing bearings show scoring, excessive wear or damage.
A 0.50 mm undersize bearing is required only when the crankshaft journals have been machined to the corresponding specification.
Checks & Installation
Measure crankshaft journal dimensions and bearing oil clearances before installation.
Inspect the connecting rods, crankshaft surfaces and oil passages for wear or damage. Installation should follow Porsche engine rebuilding specifications.
