# 859765 Lock | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta lock for engines up to serial number 5100598713, from the Engine group, weighing 0.01 kg and listed for 5 applications across the TMD, MS and MD series. The serial breakpoint is what identifies it — engines built after that number take a different item.

## ⚠️ Common Signs of Failure

-   Fixing found backed off or slack in service
-   Lock tab cracked, torn or already bent flat
-   Fixing rotating with no locking action left
-   Component moving because the fixing has lost its clamp

## 🛠️ Service Notes

-   Locking tabs and plates are single-use — fit a new one rather than bending an old tab back
