Chevrolet Avalanche Lash Adjuster

The Lash Adjuster in Chevrolet Avalanche vehicles corresponds in raising the valve closer to the camshaft to enable the vehicle to run with minimal wear which helps in increasing the life of the engine. This one is also referred to as a tappet and what it does is translate the circular motion of the camshaft into the straight up and down movement required for the valves to open and close both the intake and the exhaust. Chevrolet Avalanche models have employed different types of Lash Adjusters; solid, hydraulic and roller. Hydraulic lifters are most preferred since they can self-adjust for clearance by use of oil pressure and thus will require minimal adjustment. In recent years roller tappets are used in preference because of lower friction and improved performance, indicating the sophistication of engines. The type of valve lifter selected can do a lot in determining the performance of the engine as well as determine the frequency of the service.

Each OEM Chevrolet Avalanche Lash Adjuster we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

    A: Begin with taking off the camshaft by unscrewing or unbolting the Rocker Arms, push rods, Intake Manifolds, Timing Chains, cam sprocket and balance shaft drive gear; in addition, you may have to do away with such things as fan radiator and condenser. Place the lash adjusters in a labeled box and disconnect the lash adjuster retainer. A special tool can be employed together with magnet or even your fingers to extract the lash adjusters from their bores. Remove the camshaft retainer plate and use three 6-inch long, 5/16-18 bolts as a handle to remove the camshaft from block. When inspecting clean lash adjuster & cam shaft using solvent checking for wear on both of them. The journals as well as cam lobes should be checked for wear. Measure. If its damaged then it must be replaced along with bearings. To lubricate bearing journals and cam lobes with assembly lube, the camshaft will finally slide into engine during installation. Fix other parts like this: install that thrust plate for a Cam Shaft; balance shaft drive gear plus also timing chain & sprockets. Lubricate lash adjusters using clean engine oil then fix them within block. The rest of installation is opposite to that of removing these components. Cooling system should be refilled at last because we are starting again after changing an engine oil filter. Finally start engine (run) and check there are no leaks.
