# 184078 Needle Roller Bearing | Genuine Volvo Penta Part

## 🔧 Product Description

This genuine Volvo Penta needle roller bearing is a precision rolling-element or raceway component used in the IPS-A planetary steering gear. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it supports the steering axle/planetary member with a low-friction needle-roller race in the IPS steering gear. Selection must be confirmed by OEM part number 184078, the exact engine/product model, serial number and installed configuration.

## 🚤 Compatibility

-   **Engine Family:** IPS, D
-   **HP Range:** 110-480 HP

## ⚙️ Key Features

-   OEM Volvo Penta part number 184078
-   Needle roller bearing
-   Net weight 0.050 kg
-   Fits IPS pod drives and D series marine diesel engines

## 🔌 Function

Supports the steering axle/planetary member with a low-friction needle-roller race in the IPS steering gear. Measure shaft and housing fits, renew contaminated lubricant and related seals, and install using force only through the race being fitted. Set preload or end float to the applicable Volvo Penta specification.

## ⚠️ Common Signs of Failure

-   Rumbling or whining from the bearing location
-   Scoring or indentation of the shaft running surface
-   Rollers seized, flattened or out of the cage
-   Increased play or vibration at the shaft
-   Steel particles in the oil

## 🛠️ Service Notes

-   Press needle roller bearings in with a correctly sized mandrel — never drive them with a hammer, and never strike the cage or the shell directly
-   Press on the marked end face of the shell and keep the bearing square to the bore; a drawn cup that tilts as it enters is scrap
-   Check the bore and shaft for wear, scoring and size before fitting, and make sure both are spotlessly clean, as a needle bearing has no tolerance for grit
-   Press to the depth called for by the workshop procedure rather than driving it hard up against a shoulder
-   Leave the protective grease in place until fitting, handle the needles with clean hands only, and prime the bearing with the lubricant specified for that assembly before it goes into service
