The GLOBELT Oil Pump Chain is crafted from high-strength metal for durability and reliability. Made up of interconnected metal links, it ensures consistent oil flow and engine lubrication.
While timing chains can generate noise due to their construction, the oil pump chain works seamlessly with the oil pump to maintain steady flow rates. Over time, it may stretch but continues to support optimal engine performance.
The Oil Pump Gear features a wheel disc with gear teeth along its edge, a central step hole, and multiple positioning holes on the front face. This design ensures precise gear alignment, minimizes vibration during operation, and guarantees smooth transmission.
The oil pump circulates pressurized engine oil, lubricating the gears, enabling the use of higher-capacity fluid gears, and helping to cool the engine.
The GLOBELT Oil Pump Guide, available in the Timing Chain Kit, is crafted from high-quality materials to provide long-lasting performance and reliability.
GLOBELT uses advanced design and cutting-edge material technology to ensure the guide operates quietly, with minimal maintenance required. This precision engineering helps maintain efficient oil flow and contributes to smooth, consistent engine performance over time.
A timing chain synchronizes the camshaft and crankshaft, ensuring precise opening and closing of the engine’s intake and exhaust valves for efficient combustion and power generation. Located inside the engine, it connects components like the timing gear, guide, adjuster pump, and oil pump chain, relying on engine oil for lubrication.
Regular oil maintenance is crucial to its performance and durability, as insufficient lubrication can lead to wear and engine damage. Unlike belts, timing chains are durable and transmit mechanical power via a roller chain meshing with sprocket gears, with some featuring signaling links for easier installation and maintenance.
The timing gear ensures proper engine timing by allowing the camshaft and crankshaft to turn the timing chain. The crankshaft moves pistons up and down inside the cylinders, while the camshaft controls the opening and closing of intake and exhaust valves. These actions are essential for the air-fuel mixture to enter and remain in the cylinders and for exhaust gases to be expelled.
The timing gear, connected to the crankshaft and camshaft by a chain, belt, or gears, prevents chain slippage, maintains tension, and minimizes space. It features timing marks around its perimeter to help set the optimal timing degrees for engine performance. These marks are critical near top dead center (TDC), where the piston reaches its highest point in the cylinder, ensuring precise valve timing for efficient operation.
A timing guide serves as a track for the timing chain, connecting the crankshaft and camshaft, and is crucial for maintaining proper tension to prevent chain flutter during engine speed changes. It acts as an indicator of the timing chain system’s health, including the chain, sprockets, tensioners, and oil pressure.
Abnormal wear patterns can reveal issues like crankshaft or camshaft endplay, insufficient lubrication, or faulty tensioners. Timing guides are designed to last the engine’s lifespan, withstand high temperatures, forces, engine oil, and vapors, but premature wear or breakage may result from poor maintenance, high mileage, failed components, overheating, or blocked oil passages.
The Timing Adjuster Pump is a high-precision component designed to optimize chain tension quickly and efficiently, using oil pressure to eliminate slack in the timing chain. It ensures the chain runs smoothly around the crankshaft and camshaft sprockets, preventing rattling, slippage, or dislodgment while protecting other components like alternators and water pumps from damage.
Over time, wear and tear can cause the chain to stretch, increasing vibration and leading to tensioner wear. Signs of a malfunctioning timing adjuster pump include engine rattling noises, loss of engine power, and difficulty starting the vehicle, all of which indicate a failing timing chain system requiring immediate attention.
Oil seals, also known as rotary shaft or grease seals, are essential in closing the gap between stationary and moving components, primarily in rotating shafts. They help prevent lubricant leakage while blocking harmful contaminants like dirt from entering. Commonly used in gearboxes and hydraulic cylinders, oil seals maintain lubrication and protect shafts and bearings.
Their key functions include preventing lubricant escape, retaining lubricating oil, and stopping dirt or contaminants from entering the unit. Features of oil seals include a nose gasket to prevent leakage, a lip design for excellent followability, a linear contact sealing edge for high durability at high speeds, and rubber material with self-lubricating properties.
The oil pump chain plays a crucial role in circulating engine oil to lubricate parts like pistons, camshafts, and bearings, helping reduce friction and heat while enhancing engine cooling. Made from high-grade alloys such as stainless steel and forged steel, the chain is designed to fit securely within the oil pump.
A poor-quality oil pump chain can be damaged by excessive temperature, corrosion, dirt, and debris, or cheap materials. Symptoms of a failing chain include a glowing engine indicator, fumes from the bonnet, engine overheating, and cracking noises.
The oil pump gear is responsible for drawing in and expelling oil to provide lubrication to an engine’s internal components. Its main function is to circulate pressurized oil to the bearings, pistons, and camshaft, reducing friction and assisting in engine cooling. The oil is trapped between the lobes and sent through the pump’s discharge tube, while a pressure relief valve helps maintain the proper function of rotor-type pumps.
Faulty oil pump gears can be caused by high pressure, engine overheating, temperature changes, poor-quality oil, or head gasket failure. Symptoms include black smoke, oil leakage, and ticking noises from the pump.
Oil pump guides are critical indicators of the health of the oil pump chain, sprockets, and the engine as a whole. They are designed to maintain chain tension and prevent fluttering during engine speed changes. Though built to wear over time, they should last for the engine’s lifespan. Premature wear of the guides signals issues with the chain path, lubricants, or tensioners.
Made to withstand high temperatures, engine oil, and harmful vapors, these guides also help assess if tensioners and oil pressure are functioning properly. A broken or cracked oil pump guide often indicates poor maintenance, high mileage, failed components, or issues like a damaged tensioner or blocked oil passages, which can accelerate timing chain failure.
The timing belt break more often because of a age. Just imagine what is happening to that chain as it spins in your engine at 4000 rpm. Timing is everything and the chain is the key timekeeper. At some point they just wear out no matter what you do to maintain. If you have an engine with a chain that has already gone 150,000 miles replace it for peace of mind and financial security.
Another cause of the breakdown of the timing chain component is failure of plastic guide rails. This relates specifically to the V8 gas engines but can also apply to other engines. It is common for the upper guide rails to break off. In some cases the plastic can get sucked up into the sprocket and cause the chain to jump timing. We have new upgraded genuine guide rails available along with instructions on how to install them. Don’t neglect this to the peril of your engine.
The engine’s timing will be messed up resulting in piston and valve collision.
Engine stops running. This can only be rectified with a very expensive general overhaul.
If the car is driven fast when the chain breaks, the engine block may crack. This would be very expensive to fix as it results in a total engine replacement.
Unless there is a specific fault, the timing chain should be replaced between 80,000 and 120,000 miles. Chain problems are frequent in automobiles with increasing mileage. If you’re driving an older car or one with a lot of miles on it, keep an eye out for signs that the timing chain is failing. Because the timing chain might break and require replacement, it’s critical to be able to spot the symptoms and have it serviced before it completely fails.
It is important for checking the oils levels of engine and changing them every year or after some milage is crucial for vehicle to keep the timing chain in good condition. Lubricating oil is essential keep the chain clean, as dirt (dust, rust, metal residues) is collected by the fluid, preventing the chain links from deteriorating due to excessive frictions.
Timing chains are being used more and more in modern engines. They are more durable and usually do not have a recommended replacement interval. Although the timing chain does not require maintenance per se, it does require constant lubrication. The engine does this normally as it runs. However, low oil level or using a poor-quality oil will keep the timing chain from being properly lubricated. A timing chain can last a few hundred thousand miles with regular oil changes using high quality oil.
The very nature of a chain unit means that failure often means total calamity. If the chain breaks, the part will no longer do its job and, unfortunately, the car will no longer be able to run since the chain is a heavy metal piece, which, if it breaks, can damage the engine block, the cylinder head, and even bend the crankshaft. Usually, if the chain breaks, you will likely need a completely new engine.
