Current parts references associate this bearing with the lower-unit assembly on DPH-A, DPH-B, DPH-C, DPH-D, DPH-D1, DPR-A, DPR-B, DPR-C, DPR-D, and DPI-A drives. Because bearing fitment within a drive family can vary by production break and lower-unit configuration, confirm the part number against your exact drive serial number before ordering.\u003c\/p\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eVolvo Penta DPH-A sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPH-B sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPH-C sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPH-D \/ DPH-D1 sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-A sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-B sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-C sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPR-D sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003cli\u003eVolvo Penta DPI-A sterndrive — propeller shaft \/ lower unit (verify by serial)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131484647460\"\u003eVolvo Penta DPH \/ DPR Inner Shaft Sealing Ring – 22876829\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/8131532881956\"\u003eVolvo Penta Needle Roller Bushing 984224 – DPH DPR Drive Shaft Lower Unit\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSerial Number \u0026amp; Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eBearing fitment on Volvo Penta DPH and DPR drives is highly specific to the drive model, production serial range, and lower-unit configuration.

Inspect during any lower-unit or propeller shaft service, at each haul-out where the drive is inspected, or any time bearing noise, vibration, or excessive play is noticed. Replace proactively when the lower unit is disassembled for other service if the bearing shows wear.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical FAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eCan I confirm fitment without the drive serial number?\u003c\/strong\u003e\u003cbr\u003eNot reliably. DPH and DPR drives span multiple production generations and lower-unit configurations. Bearings that look similar may occupy different positions within the same drive family. The drive serial number is required to locate the correct schematic position and confirm 425784 is the right part for your specific unit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere is this bearing located in the drive?\u003c\/strong\u003e\u003cbr\u003eCurrent parts references place 425784 in the propeller shaft \/ lower unit assembly on DPH and DPR drives. The exact diagram position should be confirmed using the Volvo Penta parts schematic for your specific drive model and serial range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace related seals at the same time?\u003c\/strong\u003e\u003cbr\u003eYes. When the lower unit is disassembled to the point where this bearing is accessible, it is good practice to inspect and replace related seals such as the \u003ca href=\"\/products\/8131484647460\"\u003eDPH\/DPR inner shaft sealing ring 22876829\u003c\/a\u003e.

Volvo Penta’s official parts shop lists 425784 as a current genuine part. No public supersession to a new number has been identified; 425784 remains the primary ordering reference.\u003c\/p\u003e\n\n\u003chr\u003e\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eBearings in DPH and DPR lower units are not interchangeable by eye — similar bearings can sit in different positions within the same drive family and have different load requirements. The serial number is essential here, not optional. The most common issue is a customer arriving with the old bearing in hand and assuming a dimensional match is sufficient; it may look right but be wrong for that housing position.
