88800318 Piston Ring Compressor | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta piston ring compressor 88800318, weighing 4.139 kg and superseding 88800225, which was catalogued earlier as an adapter. Volvo Penta's own special tools catalogue lists twelve products against it: the D11 4f JP and the TAD1140VE to TAD1172VE industrial engines. Other compressors in the same catalogue group are listed against different engines, 9990044 against the D11 range and 9998531 against the D13 range, so the product list is what matches a compressor to a bore.

⚙️ Key Features

• 4.139 kg
• Supersedes 88800225, catalogued earlier as an adapter
• Listed for the D11 4f JP and the TAD1140VE to TAD1172VE industrial engines
• Compressors 9990044 and 9998531 cover different engines again

🔌 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

• The superseded number 88800225 was listed under a different name, so check the tool list for your engine rather than matching on description alone
• Oil the rings and the compressor bore before entry, and stop if the piston will not push in by hand
