# 9995031 Piston Ring Compressor | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta piston ring compressor weighing 0.771 kg. It squeezes the piston rings into their grooves so the piston can be entered into the bore without a ring catching on the bore edge and breaking.

## ⚙️ Key Features

-   Piston ring compressor
-   0.771 kg
-   Holds the rings compressed during piston entry
-   Prevents rings catching on the bore edge

## 🔌 Function

Compresses the piston rings flush into their grooves so the piston can be entered into the cylinder bore cleanly.

## ⚠️ Common Signs of Failure

-   Band no longer closing evenly all round
-   Inner face scored, burred or worn so it marks the rings
-   Ratchet, screw or clamp slipping under tension
-   Distortion or a step where the band overlaps
-   Rings breaking on entry despite the compressor being used

## 🛠️ Service Notes

-   Oil the rings and the inside of the compressor before entering the piston, and check the band sits flat on the block deck
-   If a ring catches, stop and withdraw the piston rather than tapping harder — a broken ring in the bore means starting again
