Double ball bearings in the Velvet Drive series carry both radial and axial loads on primary rotating shafts — they are precision components that maintain shaft alignment and absorb thrust forces generated during forward and reverse operation. At this price point, part 4920A is a significant bearing assembly, typically located at a primary shaft support position within the transmission. It is replaced during a full rebuild or when bearing failure is confirmed through noise, vibration, or inspection.\u003c\/p\u003e\n\n\u003ch3\u003ePart Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 4920A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Borg Warner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Double Ball Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Family:\u003c\/strong\u003e Velvet Drive – 71 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Marine transmission – shaft support \/ load bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagram Position:\u003c\/strong\u003e Primary shaft bearing location — refer to your Velvet Drive 71 series parts diagram for exact position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New OEM replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBorg Warner Velvet Drive 71C series marine transmissions\u003c\/li\u003e\n\u003cli\u003eBorg Warner Velvet Drive 71 series variants where part number 4920A is specified\u003c\/li\u003e\n\u003cli\u003eMarine inboard applications where 4920A appears in the transmission parts diagram\u003c\/li\u003e\n\u003cli\u003eAlways confirm fitment against your transmission model number, ratio, and parts diagram before ordering — Velvet Drive bearing part numbers are position-specific\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDuring a full Velvet Drive 71 series transmission rebuild\u003c\/li\u003e\n\u003cli\u003eWhen the bearing shows pitting, spalling, roughness, or play on inspection\u003c\/li\u003e\n\u003cli\u003eWhen rumbling, grinding, or vibration is traced to the bearing location inside the transmission\u003c\/li\u003e\n\u003cli\u003eWhen shaft end-play or radial play exceeds service limits specified in the Velvet Drive service manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDouble ball bearing replacement requires full transmission disassembly — refer to the Velvet Drive 71 series service manual for the correct procedure and bearing press specifications\u003c\/li\u003e\n\u003cli\u003eUse the correct bearing driver or press to avoid damaging the bearing races during installation\u003c\/li\u003e\n\u003cli\u003eInspect the bearing bore and shaft journal for wear, scoring, or out-of-round condition before installing\u003c\/li\u003e\n\u003cli\u003eReplace all seals and gaskets disturbed during disassembly — do not reuse old seals\u003c\/li\u003e\n\u003cli\u003eVerify correct bearing orientation and preload as specified in the service manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does “double ball bearing” mean?\u003c\/strong\u003e A double ball bearing has two rows of ball elements, allowing it to carry both radial loads (perpendicular to the shaft) and axial\/thrust loads (along the shaft axis) simultaneously — making it suitable for primary shaft positions in a marine transmission.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow do I confirm this is the correct bearing for my transmission?\u003c\/strong\u003e Locate the model plate on your transmission, note the model number and ratio, then cross-reference part number 4920A against the Velvet Drive 71 series parts diagram for your specific unit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I replace just this bearing without a full rebuild?\u003c\/strong\u003e Accessing this bearing requires full transmission disassembly.

Also worth noting: when replacing a relay, always inspect the socket and surrounding terminals for corrosion or heat damage. A corroded socket can cause the new relay to fail prematurely.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I test a relay before replacing it?\u003c\/strong\u003e\u003cbr\u003eA: A relay can be tested with a multimeter or by swapping it with a known-good relay of the same part number. Listen for the click when the control circuit is energized — if the relay clicks but the load circuit doesn’t activate, the relay contacts have likely failed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use a generic relay with the same pin layout?\u003c\/strong\u003e\u003cbr\u003eA: While generic relays with matching pin layouts may fit physically, the OEM relay is specified for the correct switching current, coil resistance, and contact rating for the Volvo Penta circuit.
