🔧 Product Description

A threaded closure plug used in the oil-filter housing on later-production Volvo Penta TAD1140VE, TAD1141VE and TAD1142VE engines. It seals the designated lubrication passage.

🚤 Compatibility

  • Engine Family: TAD, D, TWD

Full model list at the end of this description.

⚙️ Key Features

  • Correct thread and sealing profile
  • Replace if threads or sealing face are damaged
  • Direct replacement where part number 21235758 is specified
  • Engine type: TAD11 inline-six turbocharged industrial diesel

🔌 Function

Closes and seals a lubrication passage in the oil-filter housing.

⚠️ Common Signs of Failure

  • Oil seepage around the plug
  • Rounded or damaged tool drive
  • Missing sealing ring
  • Falling engine-oil level

🛠️ Service Notes

  • Clean the threads and the seating face before fitting, and make sure the opening itself is clear of old sealant, swarf and corrosion
  • Renew the sealing washer or O-ring where one is fitted rather than reusing a flattened one, and only use thread sealant where the workshop manual for your engine calls for it
  • Tighten to the figure given in the workshop manual for your engine — plugs in aluminium and other soft castings strip easily, and a plug pulled up hard to cure a leak usually distorts the seat and makes it worse
  • Where the plug closes an oil, fuel or coolant passage, run the engine up to temperature afterwards and check the joint under pressure before signing the job off
  • Keep removed plugs paired with the holes they came out of during a strip-down — plugs of very similar appearance often differ in thread, reach or sealing type
