Timing belts are used to drive camshafts, balance shafts, fuel injection pumps, or water pumps.
Timing belts are essential for ensuring the synchronized transmission of the engine's timing system.
Their function is to drive camshafts, balance shafts, fuel injection pumps, or water pumps. ChiBOSS offers high-quality timing belts that you can trust.
We provide timing belts made of CR (chloroprene rubber) and HNBR (hydrogenated nitrile butadiene rubber) materials. The lifespan of the product varies depending on the quality, typically ranging from 60,000 to 250,000 kilometers. The minimum order quantity for a single specification is at least the natural quantity of one mold.
The main material of the belt body is high-quality synthetic chloroprene rubber (CR) or hydrogenated nitrile butadiene rubber (HNBR), both imported from Japan and mixed with various additives for different purposes. The skeleton material is high-quality glass fiber cord imported from Japan. The tooth surface is protected by nylon 66 high-elasticity fabric and strictly manufactured according to technical specifications. It has the characteristics of neat appearance, full tooth shape, long service life, and low noise. Chloroprene rubber can be used for a long time in working environments up to 120℃. It has good aging resistance, especially ozone resistance. It has good chemical stability and is resistant to general chemical substances, except for strong oxidizing acids. It is also resistant to combustion and water. Hydrogenated nitrile butadiene rubber has extremely low oil swell and excellent oil resistance. It has good durability and better dynamic abrasion resistance than chloroprene rubber, reducing noise and effectively extending the product's service life. It is the preferred choice for medium to high-end automotive drive belts. Timing belts made of hydrogenated nitrile butadiene rubber can operate in the range of -40℃ to +150℃. Their durability is increased by more than 1.5 times, belt width is reduced by 20%, and heat resistance is improved by 10℃. Therefore, in terms of fatigue life and water resistance, they are superior to timing belts made of chloroprene rubber and chlorosulfonated polyethylene.
(1) When purchasing, pay attention to the cleanliness of the product surface. The belt should not be twisted or deformed, and the teeth should be full. (2) During transportation and installation, it is strictly prohibited to bend the belt, as it may damage the skeleton material (glass fiber) and affect the strength of the belt. (3) During installation and use, the belt should not be scratched intentionally, and it should not come into contact with chemicals (especially strong oxidizing acids). Avoid long-term exposure to oil and water to avoid affecting the product's service life. (4) Installation guide for timing belts: (1) Remove all drive belts, pulleys, and components that hinder the movement of the belt casing, and then remove the timing belt casing. (2) Rotate the camshaft clockwise to the "TDC" mark, and the distributor should be aligned with the No.1 ignition position of the cylinder. (3) Loosen the tensioner and remove it from the belt, while removing the timing belt. (4) Check if the chain teeth, tensioners, pulleys, and idlers are rusty, and remove any oil and grease, as they can affect the service life of the belt. (5) Adjust and ensure that all timing marks are aligned, then assemble the new timing belt onto the pulleys. (6) Loosen the adjustment screw of the tensioner to allow the pulleys to move freely, and make sure the tensioner spring is fully engaged. (7) Rotate at least two turns clockwise to ensure that the timing belt is tightly grasped by the tensioner, and check the timing marks again. (8) Install the tensioner in the appropriate position and tighten the screws to the torque setting recommended by the manufacturer. (9) Reinstall the timing belt casing and all drive belts, pulleys, and other components. (10) Start the engine, check the ignition timing, and make necessary adjustments.
