3840033 Filter Insert | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta filter insert from the Inlet and Exhaust System group, weighing 1.41 kg and listed for 6 applications across TD and TAD series engines. It supersedes 20405827, which was catalogued earlier simply as a filter. At 1.41 kg it is clearly the smallest of the three filter inserts here.

⚙️ Key Features

• Supersedes 20405827, previously listed as a filter
• 1.41 kg — the smallest of the three filter inserts here
• 6 applications across TD and TAD series engines
• Inlet and Exhaust System filtration

🔌 Function

Traps dust and airborne debris before it can reach the turbocharger and cylinders, protecting the compressor wheel and bores from abrasive wear.

⚠️ Common Signs of Failure

• Power down and exhaust smoke up under load
• Element visibly clogged, oily or discoloured
• Restriction indicator tripped
• Media damp or collapsed after water ingress
• Dust tracks on the clean side showing the element has been bypassed

🛠️ Service Notes

• Filter inserts 3840034 at 2.22 kg and 3840036 at 2.29 kg are the larger sizes here and are only 68 grams apart, so measure or order by part number
• Check the housing seal and the clean-side ducting for dust tracks — a leak past the element is worse than a blocked one
