Part Details
- Part Number: 3586568
- Brand: Volvo Penta
- Type: Seal — lower gear unit / gear housing
- System: IPS propulsion drive — lower gear unit, propeller-shaft area
- Diagram Position: Lower gear housing beside propeller nut 3861207, splined sleeve 3861201, lock plate 3861088, and propeller-cone / spinner components
- Qty Per Assembly: 1 per applicable lower gear unit
- Weight: Approx. 0.102 kg
- Important: Several visually similar seals and O-rings occupy nearby positions in the same IPS lower gear assembly. Confirm by the exact 3586568 diagram position — do not order by appearance or size alone.
About This Part
Genuine Volvo Penta 3586568 is an OEM lower gear unit seal used in Volvo Penta IPS marine propulsion drives. Parts diagrams place it in the lower gear housing beside the propeller nut, splined sleeve, lock plate, and propeller-cone components, identifying it as a specific IPS drive seal rather than a general engine seal. It is confirmed across multiple IPS drive generations from IPS-A through IPS-F and IPS10-A. Because several sealing components occupy nearby positions in the same lower gear assembly — including sealing-ring kit 3842290 and O-rings 925096 and 968241 — the correct part must be confirmed from the exact diagram position for the specific IPS drive being serviced.
Compatible Applications
- Volvo Penta IPS-A — lower gear unit
- Volvo Penta IPS-B — lower gear unit
- Volvo Penta IPS-C — lower gear unit
- Volvo Penta IPS-D — lower gear unit
- Volvo Penta IPS-E — lower gear unit
- Volvo Penta IPS-F — lower gear unit
- Volvo Penta IPS10-A — lower gear unit
Confirm the exact IPS drive model and lower-gear-unit diagram before ordering. The IPS lower gear assembly contains several different sealing components at nearby positions — 3586568 is distinct from the propeller-shaft sealing-ring kit (3842290) and adjacent O-rings.
Nearby Sealing Components — Same Lower Gear Assembly
The following parts occupy different positions in the same IPS lower gear unit and are not interchangeable with 3586568:
- 3842290 — Sealing Ring Kit (propeller-shaft sealing)
- 3842288 — Blue Sealing Ring
- 3842286 — Brown Sealing Ring
- 925096 — O-Ring
- 968241 — O-Ring
These are separate components at different diagram positions. If water intrusion into the lower gear unit is suspected, inspect all sealing components in the assembly before ordering.
Components in the Same Assembly Group
- 3861207 — Propeller nut
- 3862108 — Hex socket screw
- 3586568 — Seal (this part)
- 3861201 — Splined sleeve
- 3861088 — Lock plate
- 3861209 — Lock ring
When to Replace
Replace this seal when inspection reveals any of the following:
- Visible damage or deformation of the seal
- Hardening or loss of sealing elasticity
- Visible leakage in the lower gear housing area
- Water intrusion into the drive lubricant
- Damage discovered during lower gear or propeller-shaft service
- Wear around the sealing surface
Any suspected water intrusion into an IPS lower gear unit should also prompt inspection of the related propeller-shaft seals and sealing-ring kit 3842290, as water contamination typically affects multiple sealing points simultaneously.
Installation Notes
Before installation, inspect the complete lower gear sealing area including the mating surface, splined sleeve 3861201, propeller hardware, and adjacent sealing rings. Use the applicable Volvo Penta IPS workshop procedure when installing this seal or performing any lower gear unit service. Do not reuse a seal that has been removed — replace with a new OEM part and confirm the correct diagram position before assembly.
Cross-Reference Part Numbers
- OEM: 3586568
- Note: No confirmed Volvo Penta OEM superseding number identified. 3586568 remains the active service number across IPS-A through IPS-F and IPS10-A.
Parts Desk Insight
3586568 is a specific IPS lower gear-unit seal, and the most common issue when ordering IPS lower gear seals is selecting the wrong component because several visually similar seals and O-rings sit next to each other in the same propulsion assembly. Matching the exact diagram position for 3586568 is the only reliable method — do not order by appearance or size. If the lower gear unit is being opened for any reason, it is worth inspecting all sealing components in the assembly at the same time, as the sealing-ring kit 3842290 and adjacent O-rings are inexpensive relative to the labour cost of a repeat lower gear service on an IPS drive.
