# 991173 Roller Bearing | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta roller bearing weighing 0.633 kg and listed for 30 applications across the D and IPS series. It is the lighter of the two bearings in this run — the needle roller bearing 993204 is published at 1.252 kg over 17 D and IPS applications — but no bore, outside diameter or width is published for either, so confirm the application rather than working from the weight.

## 🚤 Compatibility

-   **Engine Family:** D, IPS

## ⚙️ Key Features

-   0.633 kg
-   30 applications across the D and IPS series
-   No published bore, outside diameter or width
-   Distinct from the needle roller bearing 993204

## 🔌 Function

Carries a rotating shaft on hardened rollers, supporting its load while keeping friction and running clearance under control.

## ⚠️ Common Signs of Failure

-   Rumbling, growling or a cyclic whine that rises with shaft speed
-   Roughness or notchiness felt when the shaft is turned by hand
-   Play or rock at the shaft that was not there before
-   Bright metallic glitter in the drained oil
-   Races or rollers found spalled, pitted or blued on strip-down

## 🛠️ Service Notes

-   Renew the mating seals and any shims disturbed on the same strip — several graded shim sets in this group serve bearing stacks on the same D and IPS applications
-   Look for the cause before condemning the bearing: contaminated or low oil and a picked-up shaft will destroy a new bearing just as fast
