993987 Needle Roller Bearing | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta needle roller bearing weighing 0.386 kg and listed for 13 applications across the D series and IPS drives. It is one of two bearings in this range, alongside ball bearing 993430 at 1.406 kg - a needle roller carries its load on long thin rollers, so it takes radial load in a much shallower housing than a ball bearing would need.

🔌 Function

Carries radial load on its needle rollers while letting the shaft turn freely, in less radial space than a ball bearing of the same capacity.

⚠️ Common Signs of Failure

• Rumbling or growling that rises with speed
• Roughness or notchiness when the shaft is turned by hand
• Play felt when the shaft is rocked
• Rollers or track found pitted, flaked or blued on strip-down
• Metallic glitter in the oil

🛠️ Service Notes

• Check the shaft journal as well as the housing - a needle roller runs directly on the shaft surface in many positions and a scored journal will destroy a new bearing
• Renew any seal disturbed on removal
• Press only on the race being fitted, never through the rollers

📦 Condition

• Genuine Volvo Penta part

• Supplied in original or equivalent packaging
