22037504 Tool | Genuine Volvo Penta Part

🔧 Product Description

Special retaining pin used to compress and lock the camshaft timing-chain tensioner while the timing chain, camshaft actuator and sprockets are removed or installed. Removing the pin after final timing alignment releases the tensioner against the chain guide.

⚙️ Key Features

• Volvo Penta workshop designation for GM EN-46330
• Locks the timing-chain tensioner in its compressed position
• Prevents uncontrolled tensioner extension during timing work
• Used during camshaft actuator and timing-chain service
• Small precision pin; not a general-purpose drift
• Engine type: Volvo Penta GM-based direct-injection marine petrol V6 and V8

🔌 Function

Holds the timing-chain tensioner compressed so the camshaft actuator, chain and sprockets can be installed with the timing marks correctly aligned.

⚠️ Common Signs of Failure

• Damaged threads, pins or retaining features
• Corrosion affecting fit or dimensional accuracy
• Evidence of overloading or impact damage
• Missing adapters or incomplete tool assembly

🛠️ Service Notes

• Special tools are matched to particular engine and drive families — check the tool against the procedure in the workshop manual for your engine before ordering, as an almost-right tool will damage what it touches
• Use the tool only for the operation it was designed for, and do not add bars, extensions or leverage to make it reach further or pull harder than intended
• Inspect before every use and retire anything cracked, bent, spread at the jaws or worn in the threads rather than persevering with it
• Clean, dry and lightly oil the tool after use and store it where the working faces cannot be knocked out of true
