Supersession Information
This part (21750952) has been superseded by Volvo Penta part number 22769792. Contact us or your Volvo Penta dealer to confirm current availability of the superseding part for your application before placing an order.
When to Replace
Replace the engine bracket when the original is cracked, bent, corroded, or no longer providing proper support and alignment at the engine mounting point. Also inspect during engine removal or any service that requires disturbing the engine mounts. A damaged or fatigued engine bracket can cause misalignment, increased vibration, and accelerated wear on the drivetrain and engine mounts.
Installation Notes
- Confirm the correct side (left-hand / port) and serial number match before installation
- Compare the new bracket to the original component before installing
- Inspect related engine mounts, fasteners, and surrounding support structure during installation
- Verify engine alignment after bracket replacement — improper alignment can cause vibration and drivetrain damage
- Torque all fasteners to Volvo Penta specification for your engine model
Parts Desk Insights
Best Use Case: Engine brackets are most commonly needed after impact damage, corrosion failure, or during a full engine removal and refit. This is not a part to defer on — a cracked or fatigued bracket can lead to engine misalignment, which puts stress on the shaft, coupling, and transmission over time. Getting the correct side (left-hand) and confirming the serial number match are the two most important steps before ordering.
Common Questions: Customers sometimes ask whether the left and right brackets are interchangeable — they are not. The left-hand and right-hand brackets are mirror-image parts with different mounting geometry. Also note that this part has been superseded by 22769792 — if you need a new bracket, it’s worth checking whether the current superseding part is available for your application.
Technical FAQ
Q: How do I confirm this is the correct bracket for my engine?
A: Use your engine serial number to look up the engine mounting diagram in the Volvo Penta parts catalog for your specific D3 variant. The left-hand bracket will appear in the engine mounting group. Contact us with your serial number if you need help confirming.
Q: This part has been superseded — should I order 21750952 or 22769792?
A: If 22769792 is available and confirmed for your application, it is the current OEM replacement. Contact us or your Volvo Penta dealer to confirm availability and fitment of the superseding part before ordering.
Q: Can I weld or repair a cracked engine bracket?
A: Volvo Penta does not recommend repairing structural engine mounting components. Replace with the correct OEM bracket to ensure proper load rating and alignment.
