When to Replace
Replace this bearing when the original shows signs of wear, roughness, noise, play, or corrosion. Also replace during major engine or drive overhauls when the bearing has been removed and cannot be confirmed as serviceable. Running a worn or damaged bearing can cause accelerated wear to surrounding components and lead to more extensive damage.
Installation Notes
- Confirm the correct part number against your engine or drive serial number and parts diagram before installation
- Use the correct bearing installation tools — never drive a bearing into place with direct hammer blows on the race
- Ensure the bearing seat and housing are clean and free of damage before installation
- Follow Volvo Penta torque and preload specifications for your specific application
- Inspect adjacent seals, races, and related components and replace as needed during the same service
Parts Desk Insights
Best Use Case: This bearing is most commonly needed during engine or drive overhauls, or when diagnosing noise, vibration, or play in a rotating assembly. At 0.9 kg, this is a substantial bearing — likely associated with a drive shaft, transmission, or major rotating assembly rather than a small accessory bearing. Getting the correct part number confirmed against the serial number is especially important for bearings, as dimensional differences between similar-looking parts can be very small but critical to proper function.
Common Questions: Customers sometimes ask whether a bearing with the same outer dimensions can substitute — for OEM applications, we always recommend using the correct Volvo Penta part number. Load rating, internal clearance, and material specification all matter in a marine drive application, and an incorrect bearing can fail prematurely under load. If you’re unsure whether this is the right bearing for your application, contact us with your engine or drive serial number.
Technical FAQ
Q: How do I confirm this is the correct bearing for my engine or drive?
A: Use your engine or drive serial number to look up the correct parts diagram in the Volvo Penta parts catalog for your specific model. The bearing will appear in the relevant assembly group. Contact us with your serial number if you need help confirming.
Q: What are the signs that a bearing needs replacing?
A: Common signs include unusual noise (grinding, rumbling, or whining) from the associated assembly, vibration, play or looseness in the shaft, or roughness when rotating by hand. Bearings should also be inspected and considered for replacement during any major overhaul.
Q: Can I reuse a bearing that has been removed?
A: Bearings that have been removed should be carefully inspected before reuse. Any sign of wear, pitting, corrosion, or roughness means replacement is required. When in doubt, replace — the cost of a new bearing is far less than the damage caused by a bearing failure in service.
