What This Part Does

This is the genuine Volvo Penta OEM starboard thrust plate for the upper gear housing on select DP-SMTD1 and SX sterndrive units. It works alongside the pressure plate (3852562) to manage axial load within the upper gear assembly. Getting the correct side matters the port and starboard plates in the same housing can look nearly identical but are not interchangeable.

Compatible Applications

• Volvo Penta DP-SMTD1 Marine Propulsion upper gear housing
• Volvo Penta SX sterndrive upper gear unit
• OMC Cobra drive-side upper gear applications (verify by schematic)

Serial Number Notice: Match part number 3589524 to your drive serial number and the correct Volvo Penta upper gear housing diagram before ordering. Drive-side plates and adjacent thrust hardware can vary by sterndrive family, production break, and housing version.

Dimensions & Weight

Approximate weight: 0.020 kg (20 g). Exact installed dimensions should be verified against the Volvo Penta upper gear housing schematic for your specific drive serial number.

When to Replace

Replace this plate when it shows wear, scoring, deformation, or corrosion during upper gear housing service. It is also worth inspecting any time the surrounding pressure plate, bearing cover, seal, or related drive hardware is already disassembled reusing a worn plate in this section of the upper gear unit can lead to repeat labor.

Installation Notes

Confirm the exact application in the correct Volvo Penta schematic before installation. Compare the removed part carefully against the replacement plate and inspect mating surfaces, the adjacent pressure plate, and surrounding upper gear housing components before reassembly.

Parts Desk Insights

The most common mistake with upper gear housing plates is matching by shape alone. The port and starboard thrust plates in the same assembly look nearly identical always confirm the correct side using the Volvo Penta schematic for your specific drive serial number before ordering. If the upper gear unit has been apart before, also check the mating surfaces on the pressure plate; worn contact surfaces on either piece will shorten the life of a new plate.
