Assembly Context
This pin is part of a multi-component steering-cylinder linkage. The complete assembly includes the following parts in the same linkage group:
- 21910902 / 3812269 — Steering cylinder
- 3859048 — Cable attachment
- 3859047 — Companion pin
- 3859046 — This linkage pin (item 9)
- 3859045 — Split pin (retaining pin)
- 3859052 — Retaining ring
- 3859051 — Retaining ring
Because several small pins and retaining pieces are used together and can look similar on the bench, matching by part number is safer than matching by appearance alone.
Compatible Applications
Match 3859046 to the exact steering cylinder and drive configuration before ordering. Steering linkage hardware can vary by transom assembly and steering-cylinder version.
- Volvo Penta SX-A sterndrive installations
- Volvo Penta SX-MHP sterndrive installations
- Volvo Penta SX-ALT32 sterndrive installations
- Selected SX and DPS-M drive installations
- Volvo Penta D3-140A-G / D3-170A-G / D3-200A-G / D3-220A-G sterndrive installations (selected configurations)
When to Replace
Because this pin is in the steering system, any looseness, wear, or damage should be corrected before the vessel is returned to service. Replace the pin if inspection reveals:
- Visible wear grooves or surface corrosion
- Bending or deformation
- Excessive play at the steering linkage pivot point
- Damage during steering cylinder service or disassembly
- Wear at the retaining hole or mating linkage surfaces
Installation Notes
Inspect the cable attachment (3859048), companion pin (3859047), and split pin 3859045 while the linkage is apart — all of these components are accessible at the same time and wear together. Install the pin fully and confirm secure retention before operating the steering system. Follow the Volvo Penta service procedure for the specific steering cylinder assembly and verify free steering movement through full lock-to-lock travel after reassembly.
Technical FAQ
Can I identify this pin by size instead of part number?
Not reliably. Several pins and retaining pieces in the same steering-cylinder linkage assembly look similar but serve different positions. Matching by Volvo Penta part number 3859046 and diagram position (item 9) is the safest approach.
Does steering-linkage play always mean this pin needs replacement?
Not necessarily — play can originate from multiple points in the steering linkage. Inspect all linkage hardware, including the companion pin (3859047), split pin (3859045), and retaining rings (3859051, 3859052), before determining which component is the source.
How often should steering linkage hardware be inspected?
Volvo Penta recommends inspecting the steering system as part of annual service. In harsh marine environments or high-use applications, inspect for play and corrosion at each season start. Any detected looseness should be investigated and corrected before use.
Parts Desk Insights
This pin typically comes up during hydraulic steering cylinder service or when a customer is chasing steering play in an SX or DPS-M installation. The most common issue is customers ordering only this pin when the split pin (3859045) and companion pin (3859047) are equally worn and accessible at the same time. Replacing all linkage hardware in the group during a steering service is the most effective way to eliminate play and avoid a return visit. Because this is a steering component, any looseness should be resolved before the boat goes back in the water.
