• Volvo Penta D2-40F

⚙️ Key Features

• Confirmed D1-13F application

• Transfers governor movement to the fuel-control mechanism
• Matched to the specified shafts, springs and levers

🔌 Function

The arm transfers movement within the governor linkage to regulate fuel delivery and engine speed.

• Worn pivot or elongated hole
• Excess linkage play
• Engine-speed hunting
• Failure to return to idle
• Bent or binding arm

🛠️ Service Notes

• This arm interfaces with governor 21187328, governor shaft 21187733 and intermediate lever 21192501 — if the linkage feels loose or notchy, check those mating parts before assuming the arm itself is worn
• At 0.045 kg it's the heavier of the two D1-13F governor arms; the lighter 21187738 (0.036 kg) sits elsewhere in the same linkage, so order by part number rather than by feel
