Good working conditions+standardized maintenance (standard load, highway, regular oiling, no frequent sudden braking)<br>-Camshaft body (short shaft base): 8-12 years\/800000 to 1.2 million kilometers<br>-Cam working surface, splines, bushings, oil seals and other vulnerable parts: 2-4 years\/200000 to 400000 kilometers (not part of the main shaft body, requiring regular replacement)<br>b. Moderate working conditions (occasional overloading, mixed road surface on national highways, routine maintenance)<br>-Short axis body: 5-8 years\/500000 to 800000 kilometers<br>-Cams, bushings, rollers: 1.5 to 3 years<br>c. Adverse working conditions (frequent overloading, dirt roads in mines\/construction sites, frequent emergency braking, lack of maintenance)<br>-Short shaft body: 2-5 years\/200000 to 500000 kilometers, prone to cam wear, shaft bending, and seat hole cracking<br>-Vulnerable parts: Six months to two years, oil seals and bushings are easily damaged<\/li>\n\n\n\n<li>Key factors affecting lifespan<br>a. Load: Long term overload is the main reason for shortening the service life, which will accelerate cam wear and shaft bending deformation<br>b. Lubrication: The position of the cam liner must be regularly lubricated with grease; Lack of oil will quickly wear down the cam and liner<br>c. Usage habits: frequent emergency braking, continuous braking on long downhill slopes, and high impact loads<br>d. Environment: Construction sites, saline alkali, and rainy environments are prone to water ingress, corrosion, and oil seal failure<br>e. Assembly and debugging: The brake clearance is adjusted too small, continuous dragging of the brake, and continuous high temperature accelerated wear<\/li>\n\n\n\n<li>Change the judgment criteria (do not rely solely on age and mileage, it is recommended to replace if the following situations occur)<br>-The wear groove depth of the cam working surface is greater than 1.5mm<br>-Short axis undergoes bending deformation<br>-Spline wear, slipping rolling key<br>-Wear and looseness of the shaft seat hole, and cracking of the bracket<\/li>\n\n\n\n<li>Maintenance suggestions<br>-Add lubricating grease to the camshaft liner every 10000 to 20000 kilometers<br>-Check the oil seal for oil leakage and the dust cover for damage during each maintenance<br>-Regularly check the brake clearance to avoid dragging the brakes<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":3510,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center
