20521748 Oil Pipe | Genuine Volvo Penta Part

🔧 Product Description

It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 16-litre TAD16 industrial diesel application. Technical identification: Formed oil pipe in the D16 engine lubrication circuit. In service, it transfers or controls lubricating oil so bearings, piston-cooling components and auxiliary equipment receive the required flow and pressure.

⚠️ Common Signs of Failure

• Oil weeping or spraying from the pipe or its unions
• Oil pressure lower than expected, or the pressure warning coming on under load
• Oil level falling with a wet trail along the pipe run
• On removal, chafing, cracking or fretting where the pipe passes a bracket or clip
• Union faces scored or distorted from a loose clamp or an overtightened joint

🛠️ Service Notes

• If 20521748 is changed, 20521749 must also be changed at the same time
• The catalogue records this pipe as replaced by 21081470 - confirm which number your engine now takes before ordering
• Supersedes 20502180, catalogued earlier as a return line, so the older number brings a differently shaped part
