🔌 Function

Supports the camshaft on a pressurised oil film and maintains correct alignment and running clearance.

⚠️ Common Signs of Failure

• Low engine-oil pressure at the camshaft gallery
• Camshaft knocking or abnormal valvetrain noise
• Scoring, wiping or heat discolouration
• Excessive camshaft journal clearance
• Metal contamination found during overhaul

🛠️ Service Notes

• This shell is used with camshaft 21771519 — check the camshaft fitted before ordering, and renew shells as a full set for the engine rather than one at a time, as assemblies commonly use six
• Inspect the camshaft journal before fitting a new shell; a shell that has picked up or spun will have marked the journal as well, and a new shell will not last against a damaged journal
• Bearing shells work as matched halves — order the correct pair and confirm the running clearance is within specification once assembled
