About This Part
Genuine Volvo Penta 3886957 is an OEM pipe retainer used in the engine lubrication system on selected Volvo Penta D4 and D6 marine diesel engines. Parts diagrams place 3886957 directly with oil dipstick pipe 3593955, nipple 3886951, guide 22456382, and the oil dipstick assembly, where it secures and supports the oil-level tube arrangement in the lubricating system. This is not a generic clip or cable retainer — its position is specific to the D4/D6 dipstick pipe arrangement, and the number of retainers required varies by engine configuration: selected D4 F-series assemblies use one, while selected D6 F-series assemblies use two. Confirm engine model, suffix, serial number, and the applicable lubricating-system diagram before ordering.

When to Replace
Replace this pipe retainer if it shows any of the following:
- Bending or distortion that prevents correct pipe support
- Cracking or fracture
- Corrosion affecting structural integrity
- Looseness or inability to secure the pipe in the correct position
- Damage discovered during oil pan, dipstick tube, or lubricating-system service
A damaged or missing retainer can allow unnecessary movement of the oil-level tube and its related fittings. Inspect this retainer whenever the dipstick tube or surrounding lubricating-system components are being serviced.
Installation Notes
Inspect oil dipstick pipe 3593955, nipple 3886951, guide 22456382, O-ring 944124, and associated brackets while replacing the retainer. Confirm the quantity required for your specific engine configuration from the lubricating-system diagram, and ensure the pipe is fully seated and supported in the same position shown in the applicable Volvo Penta diagram after installation.

Parts Desk Insight
The most common issue with this retainer is overlooking it entirely during dipstick tube service — technicians typically focus on the pipe and nipple, and the retainer gets reused without inspection. On D6 F-series engines where two retainers are required, ordering only one is a frequent mistake. Check the lubricating-system diagram for your specific engine suffix to confirm the correct quantity before ordering. If surrounding oil-system components are already apart, replacing this retainer at the same service visit is worthwhile, as it is inexpensive and a damaged retainer can cause tube movement and potential damage to the nipple fitting over time.
