Volvo Penta Bearing Box 22173381 – DPH DPR Sterndrive

Part Number: 22173381
Brand: Volvo Penta
Official Product Type: Bearing Box / Bearing Housing
System: Sterndrive Driveline – Drive Shaft & Bearing Housing Assembly

Overview

The Volvo Penta 22173381 is the genuine OEM bearing box (bearing housing) for the drive shaft and bearing housing assembly on selected Volvo Penta DPH and DPR sterndrives. It supports and locates the associated shaft, bearing, seal, and shim components within the upper driveline housing. This is the housing itself — not a complete bearing rebuild kit. Bearings, seals, O-rings, and shims are separate components identified individually in the Volvo Penta parts diagram.

Compatible Applications

• Volvo Penta DPH-D
• Volvo Penta DPH-D1 (including SN 3020295798 and later configurations)
• Volvo Penta DPR-D

Confirm the exact sterndrive model and serial number against the applicable Volvo Penta drive shaft and bearing housing diagram before ordering. The bearing box is part of a precision driveline assembly that uses model-specific bearings, seals, and selectable shims.

Serial Number & Fitment Notice

Bearing housing configurations vary by drive model and serial number range within the DPH and DPR families. For DPH-D1 drives, Volvo Penta parts references show 22173381 in both earlier and later drive shaft / bearing housing configurations, including the SN 3020295798 and later arrangement. Always confirm by drive model and serial number before ordering.

Dimensions & Weight

Approximate weight: 1.5 kg. Exact dimensions are not published in current Volvo Penta accessory literature. Confirm by part number and serial number match to the drive shaft and bearing housing assembly diagram.

When to Replace

Replacement may be required if the housing shows bearing-seat wear, corrosion, cracking, distortion, damaged threads, or sealing-surface damage discovered during drive shaft service. Inspect all related bearings and sealing components while the assembly is apart.

Installation Notes

The surrounding assembly includes components that are separately identified in the Volvo Penta parts diagram and are not included with 22173381:

Technical FAQ

Q: Does 22173381 include the bearings, seals, and shims?
A: No. 22173381 is the bearing housing only. Bearings, seals, O-rings, and shims are separate components identified individually in the Volvo Penta parts diagram for the drive shaft and bearing housing assembly.

Q: Does this fit all DPH and DPR drives?
A: No. Confirmed applications are DPH-D, DPH-D1, and DPR-D. Other DPH and DPR variants use different bearing housing configurations. Always confirm by drive model and serial number.

Q: How important is shim selection when installing this housing?
A: Shim selection is critical. Incorrect bearing preload in this assembly can cause premature bearing failure and driveline damage. Follow the Volvo Penta workshop procedure for the specific drive model and serial number range.

Q: How do I confirm this is the right part for my drive?
A: Match by drive model and serial number using the Volvo Penta DPH or DPR drive shaft and bearing housing parts diagram. Contact us with your drive serial number if you need confirmation before ordering.

Parts Desk Insights

22173381 is the bearing housing itself — not a complete bearing rebuild kit. The most common issue is customers assuming the bearings, seals, and shims are included. When servicing this assembly, identify all required bearings, seals, O-rings, and shims separately from the exact drive diagram before ordering. This is a precision driveline component — confirm drive model and serial number before processing the order, and ensure the customer has the full workshop procedure before starting the job.
