What This Part Does
The 22452005 is a genuine Volvo Penta OEM hydraulic steering cylinder — the main steering ram that connects the hydraulic steering system to the drive's steering linkage. When the helm is turned, hydraulic pressure moves this cylinder to push or pull the drive from side to side, providing smooth, responsive steering control. It is used on select DPH, DPR, and DPI sterndrive and transom shield assemblies where the Volvo Penta parts diagram specifically calls for part number 22452005.
Compatible Applications
Confirm fitment by drive model, drive serial number, transom shield type, steering system configuration, and the correct Volvo Penta steering diagram before ordering. Do not select by drive family alone — hose fittings, stroke, mounting geometry, and port/starboard position can vary within the same family.

Serial Number Requirement
Volvo Penta used different steering cylinders, hose fittings, mounting pins, seals, and steering layouts across similar DPH, DPR, and DPI drive families. Always confirm part number 22452005 against your drive serial number and the correct Volvo Penta steering system diagram before ordering.

When to Replace This Part
- Hydraulic fluid leaking from the rod seal, hose fittings, or cylinder body
- Steering feels loose, uneven, or requires excessive effort
- Ram rod is pitted, corroded, or scored
- Cylinder binds or sticks during steering movement
- Drive will not hold steering position or drifts off course
- Excessive play at the steering linkage connection
- Cylinder damaged by corrosion, impact, or failed seals
Installation Notes
- Inspect steering cylinder mounting pins, bushings, and retaining hardware during replacement
- Check hose fittings, hydraulic lines, and transom shield connection points for wear or damage
- If the steering system uses paired cylinders, inspect both sides — the opposite cylinder may have similar age and seal wear
- After installation, bleed the hydraulic steering system fully and cycle the drive lock-to-lock per the Volvo Penta service procedure to remove trapped air before returning to service
- Use only Volvo Penta-approved Power Trim & Steering Fluid when topping up or refilling the system
Technical FAQ
Can I use this cylinder on both port and starboard positions?
Not necessarily. Some DPH/DPR/DPI steering configurations use position-specific cylinders. Confirm the correct part for each mounting position using the Volvo Penta steering diagram for your drive serial number.
Do I need to replace both cylinders at the same time?
Not always required, but if one cylinder has failed from seal wear or rod corrosion, the opposite cylinder is likely at a similar service age. Inspecting both during the same service visit can prevent a repeat teardown.
What fluid does this system use?
Use Volvo Penta-approved Power Trim & Steering Fluid 3851039. Do not substitute with generic hydraulic fluid.

Parts Desk Insights
This is one of the more common steering-system calls on DPH and DPR drives. The most frequent issue is a leaking rod seal — usually visible as hydraulic fluid weeping from the cylinder body near the ram rod. A slow leak often goes unnoticed until steering becomes noticeably spongy or the fluid reservoir runs low. If a customer is chasing intermittent steering stiffness or a drive that wanders slightly off course, a partially failed cylinder seal is worth checking before assuming a pump or hose issue. Also worth noting: the hose fittings and mounting pin dimensions can differ between DPH generations, so confirming the serial number before ordering avoids a fitment mismatch on a high-value part.
