⚙️ Key Features

• For the 1500 rpm governor setting
• 0.010 kg
• Supersedes 863059, listed by Volvo under its Swedish name ytterfjäder, meaning outer spring
• 45 applications across TD, TWD, TMD, TID, TAMD and TAD series engines
• 2 used per assembly

🔌 Function

Sets the load the governor works against so the engine holds its speed as demand changes.

⚠️ Common Signs of Failure

• Engine hunting or surging rather than holding a steady speed
• Speed drooping under load and slow to pick up
• Set speed drifting away from its adjustment
• Coils corroded, pitted or broken
• Spring visibly shortened or the coils touching, showing it has taken a set

🛠️ Service Notes

• Regulator spring 849828 at 0.020 kg carries the same 1500 rpm note and the same 45 applications, so this pair is best ordered by number and the two are likely the inner and outer springs of one set
• Have the governor set on a test bench after fitting
