🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 27.4 kg and recorded against five applications in the TWD family. The reman catalogue lists this number against TD121G-87, TWD1230ME, TWD1210/1211/1230V, TWD1230VE and TWD1231VE, and splits the TD121G-87 entries by serial number - one up to 38631 and one from 38632 onwards - so read the serial off the engine plate as well as the designation. It consolidates 3826157 and 3826156, which between them covered a governor and an injection pump, so the two former orders are now one. 3803720 at 27 kg and 3803800 at 27.5 kg sit either side of it within 400 grams. Supplied on exchange: core deposit 3806740 is charged alongside it and refunded once the old pump is returned.

🔌 Function

Raises fuel to injection pressure and meters the right quantity to each cylinder in firing order, setting the engine's power and speed.

⚠️ Common Signs of Failure

  • Hard starting, or long cranking before it fires
  • Power down, with a flat spot as the throttle is opened
  • Black smoke and uneven running at idle
  • Engine speed hunting or surging
  • Diesel weeping from the pump body or the drive-end seal

🛠️ Service Notes

  • The governor is part of this assembly, so do not order one separately against the old numbers
  • On a TD121G-87 read the engine serial number - the listing separates engines up to 38631 from those from 38632 onwards
  • Have the pump timed and its fuel settings checked on fitting; core deposit 3806740 is refunded on return of the core
