This chain’s job is pretty straightforward – it physically connects the crankshaft to the oil pump. As the engine runs, the crankshaft spins, and that rotation is transferred to the oil pump via this chain. That pump then circulates oil throughout the engine to keep everything lubricated and running smoothly. It's a pretty vital mechanical link in getting oil where it needs to go. Think of it as part of the engine’s circulatory system. The crankshaft is the heart, the oil pump is… well, the pump, and this chain is a major artery. Without it, the pump won’t turn, and you’ll have absolutely no oil pressure. That's obviously a bad situation. It’s located inside the engine, usually under the front or rear cover, so it’s not something you can just visually inspect easily. It's important because oil is the lifeblood of your engine. Without proper lubrication, parts quickly wear out, overheat, and eventually fail. This chain acts like a shield, protecting your engine from that kind of damage. You’ll notice if this chain fails pretty quickly – usually with a very loud rattling noise and an oil pressure light illuminating on your dash. If that happens, stop driving immediately. You can find a replacement for a lot of vehicles over at Fixparts Online, but honestly, getting it fixed quickly is the most important thing. A broken oil pump chain can lead to catastrophic engine damage if ignored. Dedicated to your needs: Chain (MPN 11411735713) comes with a 12-month warranty!
