Engine Cam Timing Sprocket for Mitsubishi

This precision gear is a key part of the valve timing system. It sits on the camshaft and works with the timing belt/chain to keep the cam and crank perfectly synchronized. When timing is correct, the engine breathes right, starts easier, and delivers smooth power ?.

Why this part is needed

The camshaft must open and close valves at the exact moment. This sprocket provides the accurate tooth profile and alignment marks that keep timing set where the factory intended. It also helps maintain stable timing under load and high RPM ⚙️.

How it works

As the crankshaft turns, the belt/chain pulls the sprocket teeth, rotating the camshaft. The cam lobes then actuate valves in sequence. Correct sprocket indexing keeps valve events matched to piston position, protecting performance and fuel economy ⛽.

What happens if it’s worn or damaged

A bad sprocket can cause belt/chain slippage, noisy timing, rough idle, loss of power, misfires, and hard starting. In severe cases, timing can jump and lead to valve-to-piston contact on interference engines, risking major cylinder head damage ?️.

Technician tip

Replace if teeth are hooked, the keyway is loose, or timing marks are hard to read. Always inspect the belt/chain, tensioner, and oil seals during service for best reliability ✅.
