# 184852 Needle Roller Bushing | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta needle roller bushing is a needle-roller bushing designed to support a propeller or gear shaft within a compact housing used in the IPS inner propeller-shaft needle-bearing support. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it supports the inner propeller shaft and maintains radial alignment inside the IPS lower gear. Selection must be confirmed by OEM part number 184852, the exact engine or product model, serial number and installed configuration.

## 🚤 Compatibility

-   **Engine Family:** D, IPS
-   **HP Range:** 260-480 HP

## ⚙️ Key Features

-   OEM Volvo Penta part number 184852
-   Needle roller bushing, drawn-cup type
-   Net weight 0.029 kg
-   Fits D series marine diesel engines and IPS pod drive installations

## 🔌 Function

Supports the inner propeller shaft and maintains radial alignment inside the IPS lower gear. Press the bushing with a piloted tool, maintain the specified depth and orientation, and inspect the mating shaft or inner ring.

## ⚠️ Common Signs of Failure

-   Whining or rumbling at the bearing position
-   Wear ridges or scoring on the shaft or pin
-   Needles loose, missing or seized
-   Play developing at the supported component
-   Fine metallic debris in the drive oil

## 🛠️ Service Notes

-   Press only on the stamped, marked end face of the outer shell — that face is made to take the fitting load, and pressing on the opposite end will fold the thin shell over
-   Use a proper mandrel with a pilot to enter the bearing square and support the shell right across its face; never hammer directly on the shell and never press on the rollers or the cage
-   Check the housing bore is clean, undamaged and within the size the manual for your engine gives; a drawn-cup needle bearing takes its running clearance from the bore, so a worn or oval housing will ruin a new bearing
-   Inspect the shaft or journal the rollers run on and renew it if scored or worn — needle rollers mark a shaft, and a new bearing on a scored shaft will not last
-   Press to the depth the workshop manual specifies rather than clamping the shell hard against a shoulder in the housing, lubricate as the manual for your engine specifies, then turn the assembly over by hand and check it runs free before any load goes on it
