# 88800319 Piston Ring Compressor | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta piston ring compressor weighing 4.112 kg, listed in the Special Tools group. It supersedes 9990044, which was catalogued earlier simply as a tool. It is one of seven compressors in this run — 88800313, 88800314, 88800316, 88800317, 88800318, 88800319 and 88800831 — and their published weights all sit close together, so weight will not identify which bore a given compressor suits.

## ⚙️ Key Features

-   4.112 kg
-   Supersedes 9990044, catalogued earlier as a tool
-   One of seven compressors listed here — order by number, not by weight
-   Special Tools group

## 🔌 Function

Squeezes the piston rings flush into their grooves so the piston can be pushed square into the bore without a ring catching.

## ⚠️ Common Signs of Failure

-   Rings catching or breaking on entry to the bore
-   Band or taper bore scored, stepped or worn
-   Clamp not closing evenly all the way round the piston
-   Compressor scuffing or marking the piston skirt
-   Body distorted, so it no longer sits square on the block face

## 🛠️ Service Notes

-   Oil the rings and the compressor bore before entry, and stop and investigate if the piston does not push in with hand pressure
-   An order placed against the older number 9990044 will bring this tool
