Volvo Penta Roller Bearing 184849 | IPS Lower Gear Unit OEM

Volvo Penta 184849 – Roller Bearing

Part Number: 184849  |  Brand: Volvo Penta  |  Type: OEM Roller Bearing  |  Sold: Individually

This is the genuine OEM roller bearing for the lower gear unit of Volvo Penta IPS drives. Volvo Penta lower-unit diagrams place 184849 within the gear and shaft assembly, alongside selectable shims, the inner ring, needle roller bushing, and bearing carrier. It is a drivetrain-critical component — not a general-purpose bearing — and correct shim setup is required after installation.

IPS lower units use multiple bearings and selectable shims. Always confirm the exact IPS model, drive serial number, and lower-gear-unit diagram before ordering to ensure the correct bearing position and setup.

When to Replace

Replace this bearing when lower-unit inspection reveals rough rotation, excessive play, pitting, corrosion, abnormal noise, or damage during propeller-shaft or gear service. Bearing condition should also be checked whenever water intrusion or internal gearcase damage is found.

Installation Notes

Correct bearing and shim setup is critical in the IPS lower gear unit. Volvo Penta diagrams show 184849 adjacent to selectable 0.10 mm, 0.15 mm, and 0.35 mm shims — existing setup measurements should not be assumed correct after replacing gears, shafts, or bearings. Follow the applicable Volvo Penta workshop procedure for bearing installation and gear setup.

Parts Desk Insights

Best use case: This is the correct service part for technicians performing lower gear unit work on Volvo Penta IPS drives. It's an IPS gearbox-specific roller bearing — not a general engine bearing — and is most commonly needed during a full lower-unit overhaul or after water intrusion damage.

Common questions: The most important thing to flag is shim setup. When replacing this bearing, the neighboring shims need to be measured and selected fresh — don't assume the old shim stack is still correct after replacing gears, shafts, or bearings. While the assembly is apart, it's also worth inspecting the inner ring, needle roller bushing, and bearing carrier, as replacing worn neighbors at the same time avoids a repeat teardown.
