# 991660 Toothed Washer | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta toothed washer weighing 0.005 kg and listed for 101 applications across the IPS, D, V, DPH, DPI and DPR series. The plain washer 991659 carries an identical published weight and an identical application list, so the toothed profile is the only distinguishing feature — check the old washer rather than the figures.

## 🚤 Compatibility

-   **Engine Family:** IPS, D, V, DPH, DPI, DPR
-   **HP Range:** 140-480 HP

## ⚙️ Key Features

-   Toothed pattern
-   0.005 kg
-   101 applications across the IPS, D, V, DPH, DPI and DPR series
-   Identical published weight and fitment to the plain washer 991659

## 🔌 Function

Spreads the fastener's clamping load while its teeth bite into the mating face to resist the fastener backing off.

## ⚠️ Common Signs of Failure

-   Fastener backing off or the joint rattling loose
-   Teeth flattened, blunted or broken off
-   Washer dished, cupped or cracked
-   Corrosion or pitting through the washer

## 🛠️ Service Notes

-   A toothed washer that has already bitten in is a single-use item — flattened teeth no longer lock, so renew rather than refit
-   If the old washer has no teeth you want the plain washer 991659; the published weight and fitment are the same for both
