Overview
The Volvo Penta 22121309 is the genuine OEM port-side hydraulic trimming cylinder for DPH and DPR sterndrive power-trim systems. It hydraulically raises and lowers the port side of the sterndrive to control running angle and trim position. This cylinder is sold individually — the port and starboard cylinders are different components and must be ordered separately.
For DPH-D1 installations, 22121309 applies from serial number A395817 and later, superseding the earlier 21840807. The corresponding starboard cylinder is 21840806.

Serial Number & Fitment Notice
The port and starboard trimming cylinders are different components — 22121309 is the port (left-hand) cylinder only. For DPH-D1 drives, this part applies from serial A395817 onward; earlier drives used 21840807. Always confirm drive model, side, and serial number before ordering.

Dimensions & Weight
Approximate weight: 2.5 kg (hydraulic cylinder assembly). Exact dimensions are not published in current Volvo Penta accessory literature. Confirm by part number and serial number match to the applicable DPH/DPR trim system diagram.
When to Replace
Replace the trimming cylinder when it develops hydraulic leakage, corrosion or scoring on the piston rod, excessive play at the mounting points, or difficulty holding the sterndrive at the commanded trim position. Inspect both port and starboard cylinders at the same service — if one is worn, the other is likely at a similar service age.
Installation Notes
Inspect the hydraulic hoses, tubes, fittings, bushings, and mounting hardware during replacement. After installation, service and bleed the power-trim hydraulic system per the applicable Volvo Penta workshop procedure. Confirm smooth drive movement through the full trim range and check for leakage at all connections before returning the vessel to service.

Technical FAQ
Q: Is 22121309 the port or starboard cylinder?
A: 22121309 is the port (left-hand) side trimming cylinder. The starboard cylinder is 21840806.
Q: Does 22121309 replace 21840807?
A: Yes, for DPH-D1 installations from serial A395817 onward. Earlier drives used 21840807. Confirm your serial number before ordering.
Q: Do I need to replace both cylinders at the same time?
A: Not always required, but recommended if both cylinders are at similar service age or if one shows wear that suggests the other is close behind. Replacing both at the same service avoids a repeat job shortly after.
Q: What causes trim cylinder failure on DPH/DPR drives?
A: The most common causes are corrosion on the piston rod (especially in saltwater environments), seal wear from age or contaminated hydraulic fluid, and physical damage to the rod or mounting points. Regular anode service and keeping the hydraulic fluid clean extend cylinder life.
Parts Desk Insights
The most important distinction with this part is side and serial range: 22121309 is the port-side cylinder, and for DPH-D1 drives it applies from serial A395817 onward — earlier drives used 21840807. Always confirm side and serial before processing the order. If a customer is replacing one cylinder due to a leak, recommend inspecting the starboard cylinder at the same time. Also check the hydraulic hoses and fittings while the drive is apart — a cylinder replacement is a good opportunity to address any hose wear before it becomes the next service call.
