Cadillac 24100294 Arm,Valve Rocker

Removal involves removing the valve covers and the camshafts to remove the rockers is the lash adjuster socket on the rocker. Place markings on each rocker arm to ensure they are returned to the same position, then lift each one from the engine. Once the rocker arms are removed, the hydraulic lash adjusters can be lifted from the cylinder head. It is important that any rocker arms or lash adjusters being used again must be returned to their original position on the engine. Inspection involves checking each rocker arm for wear, cracks and other damage, especially where the valve stems contact the rocker arm. Check the rollers for binding and roughness. If the bearings are worn or damaged, replacement of the entire rocker arm will be necessary. Keep in mind that there is no valve adjustment on these engines, so excessive wear or damage in the valve train can easily result in excessive valve clearance, which in tum will cause valve noise when the engine is running. Make sure the oil passage hole in each hydraulic lash adjuster is not blocked. Installation involves applying some camshaft/lifter prelu be to the pivot pockets, roller and the slot that contacts the valve on each rocker arm. Apply clean engine oil into the bores for the hydraulic lash adjusters and install them into the cylinder head. Position the rocker arms onto the lash adjusters. The remainder of installation is the reverse of removal. Before starting and running the engine, change the oil and install a new oil filter.

Lift the valve covers off the cylinder heads and take out the camshafts out of the engines. Mark each of the rocker arms so that they are returned to the same position as they were removed from the engine and lift each rocker arm from the engine. After the rocker arms had been taken off, the lash adjusters were lifted from the cylinder head. In case any rocker arms or adjusters that have been used have to be reused, then they must be put back on the engine as they were. Visually inspect each rocker arm for signs of wear and stress, cracks and any other signs of damage and in the area where the valve stems touch the rocker arm. Check the condition of the rollers, they should not bind and should not be rough, if the bearings of the rollers are worn or damaged then the whole rocker arm will need to be replaced. It should be remembered that there is no valve adjustment on these engines, and therefore a worn or damaged valve train can quickly lead to excess valve clearances, which makes the valves noisy when the engine is running. Finally is the rocker arm pivot support pedestal; check for any crack or any form of noticeable damage. Verify that the oil passage hole is open in each lash adjuster, and that there are no sharp edges, or burrs, on the bottom of the adjuster. Spray some camshaft/adjuster pre-lube on the area of the pivot pocket, on the roller and on the part of the slot that touches the valve on the specific rocker arm. Pour fresh engine oil into the bores for the lash adjusters and then fit these into the cylinder head, placing the rocker arms on to the adjusters. The rest of installation is actually the reverse of removal. The oil should be changed and a new oil filter fitted before starting and running the engine and before disconnecting.

Before the valve covers can be removed the camshafts must be taken off because in order to get to the rocker arms, and the lash adjuster socket on the rocker arm, they are needed. Identify every rocker arms so that through correct orientation they will be fitted back correctly then raise every rocker arm from the engine. With the rocker arms out of the way, the hydraulic lash adjusters can now be lifted of the cylinder head and for components that are being reused, they should be reinstalled in the correct positions. To carry out this process, a rocker arm should be closely examined on each for signs of wear, cracks, and other kinds of damage at the contact zone with the valve stems and to check the rollers for binding and roughness; if the rocker arm has worn or damaged bearings, the rocker arm must be replaced. Also, check for any sign of cracks or damage of the rocker arm pivot support pedestal. Please recall that these engines do not require valve adjustments and therefore if there is wear or damage in the valve train, the chances are high that it will cause high valve clearance and produce noises during operation. Make sure the passage for the oil for each hydraulic lash adjuster is auger and not hampered by any sharp edge. For the installation, smear camshaft assembly lube on the pivot pockets, roller and the part of slot that pushes onto the valve of the rocker arm. Pour clean engine oil in the bores where the hydraulic lash adjusters go, place the rocker arms in the lash adjusters, then put the lash adjusters into the cylinder head. The procedure for installation is the exact reverse of the removal, and before starting the engine, replace the oil and the oil filter.

To remove the valve covers from the cylinder heads, first loosen the rocker arm pivot bolts one at a time and take out the rocker arms and bolts, followed by the pivot support pedestal, ensuring to keep track of the component positions for reinstallation. Store each set of components separately in marked containers to maintain their original locations, including the rocker arms and pivot support. Next, remove the pushrods and store them in order to avoid mixing them up during installation. Inspect each rocker arm for wear, cracks, and damage, particularly at the contact points with the pushrods and valve stems, and check the pivot bearings for binding and roughness; if worn or damaged, the entire rocker arm will need replacement. Ensure the hole at the pushrod end of each rocker arm is clear, and inspect the pushrods for cracks and excessive wear, checking that the oil hole is not clogged and rolling each pushrod across a piece of plate glass to detect any bends. For installation, lubricate the lower end of each pushrod with clean engine oil or assembly lube and install them in their original locations, ensuring each pushrod seats completely in the lifter socket. Apply engine assembly lube to the ends of the valve stems and upper ends of the pushrods to prevent damage during initial start-up, and also apply clean engine oil to the pivot shaft and bearing of each rocker arm before loosely installing the rocker arms in their original locations without tightening the bolts. Rotate the crankshaft until the number one piston is at TDC on the compression stroke, ensuring both pushrods for the number one cylinder are in the lowered position, then tighten the intake valve rocker arms for cylinders 1, 3, 4, and 5, and the exhaust rocker arms for cylinders 1, 2, 7, and 8, to the specified torque. Rotate the crankshaft 360 degrees and tighten the intake valve rocker arms for cylinders 2, 6, 7, and 8, and the exhaust rocker arms for cylinders 3, 4, 5, and 6, to the specified torque. Finally, install the valve covers, start the engine, and listen for unusual valve train noises while checking for oil leaks at the valve cover gaskets.

To remove the components, first disconnect the cable from the negative terminal of the battery. Next, remove the valve cover(s). Starting at the drivebelt end of one cylinder head, remove the rocker arm mounting bolts one at a time and detach the rocker arms, pivot balls, and pedestals, ensuring to keep each set of rocker arm components separately stored in marked plastic bags for proper reinstallation. The rocker arms have a pedestal mount captured by a metal sleeve inside, and while components can be separated by tapping the bolt out of the pedestal, they typically remain as an assembly. Remove the pushrods and store them separately to avoid mixing them up during installation, using a perforated cardboard box for organization and labeling the front end of the engine. Inspect each rocker arm for wear, cracks, and damage, particularly at the contact points with the pushrods and valve stems, and ensure the rollers operate freely and the pushrod end holes are open. Check the pushrods for cracks and excessive wear, rolling each across a piece of plate glass to detect any bends. For installation, lubricate the lower end of each pushrod with clean engine oil or moly-base grease and reinstall them in their original locations, ensuring they seat completely in the lifter socket. Apply moly-base grease to the ends of the valve stems and the upper ends of the pushrods, then install the rocker arm assemblies, tightening them to the specified torque while ensuring proper engagement of the pushrods in the rocker arms and correct positioning of the pedestal projections. Finally, install the valve covers, start the engine, and check for oil leaks and unusual sounds from the valve cover area.

To remove valve covers one has to briefly remove the camshafts due to the presence of a spacer and the lash adjuster socket on the rocker. Label each of the rocker arms to know how to relocate them back into position and then remove it from the engine. With the rocker arms pulled out, the hydraulic lash adjusters can be accessed and extracted out of the cylinder head, their original position should be maintained for reused items. Check each rocker arm for signs of wear, cracks, and other kinds of damage at the areas that it makes contact with the valve stem; the rollers should be slippery to slide over, but if they are binding or rough, or if they make the bearings wobble, this is a clear sign that the rocker arm needs to be replaced as the bearings it is using are spoiled. That is right, these engines do not have provision for valve adjustments and therefore any wear or damage in the valve train will cause the valve clearance to increase and there will be noise when the machine is in operation. Check that the oil passage hole existing in each hydraulic lash adjuster is free. Camshaft lifter prelube should be applied to the pivot pockets, the roller and the slot that makes contact with the valve within the rocker arm to which it will be installedThe hydraulic lash adjusters get clean engine oil put into the bores before being installed into the cylinder head and the rocker arm fitted over the lash adjusters. The last procedures in it are the reverse of the above mentioned removal process, and before starting the engine, replace the oil and insert a new oil filter.

Rotate the crankshaft until the number one piston is at TDC on the compression stroke, ensuring both pushrods for the number one cylinder are in the lowered position, then tighten the intake valve rocker arms for cylinders 1, 3, 4, and 5, and the exhaust rocker arms for cylinders 1, 2, 7, and 8, to the specified torque. Rotate the crankshaft 360 degrees and tighten the intake valve rocker arms for cylinders 2, 6, 7, and 8, and the exhaust rocker arms for cylinders 3, 4, 5, and 6, to the specified torque. Finally, install the valve covers, start the engine, and listen for unusual valve train noises while checking for oil leaks at the valve cover gaskets.

Detach the valve covers from the cylinder heads, then loosen the rocker arm pivot bolts one at a time to detach the rocker arms and bolts, followed by the pivot support pedestal, ensuring to keep track of the rocker arm positions for reinstallation. Store each set of rocker components separately in marked plastic bags. Remove the pushrods and store them separately to avoid mixing during installation, noting the arrow indicating the front of the engine. Check each rocker arm for wear, cracks, and damage, particularly at the pushrod and valve stem contact points, and inspect the pivot bearings for binding and roughness; if worn or damaged, the entire rocker arm must be replaced. Ensure the hole at the pushrod end of each rocker arm is open and inspect the pushrods for cracks and excessive wear, checking that the oil hole is not clogged, rolling each pushrod across a piece of plate glass to detect any bending.

Rotate the crankshaft 360 degrees and tighten the intake valve rocker arms for cylinders 2, 6, 7, and 8, and the exhaust rocker arms for cylinders 3, 4, 5, and 6, again tightening each rocker arm bolt to the specified torque. Finally, install the valve covers and start the engine, listening for unusual valve train noises and checking for oil leaks at the valve cover gaskets.

In order to remove the valve covers, one has to take off camshafts and tightened paying attention to the wear points of the rocker arm and lash adjusters. We need to mark the rocker arms so that they will be reinstalled in the correct location, then pull them from the engine. The hydraulic lash adjusters become physically detached with the rocker arms being removed and can be withdrawn from the cylinder head. Rocker arms or lash adjusters that were remove should be reinstall to their original position if desire. Feel the rollers to identify cases where they are rigid; if bearings of the part are worn or damaged, the whole rocker arm will have to be replaced. Just as worth remembering, these engines do not need any valve adjustments, so the excessive wear or damage in the valve train will deepen the increased valve clearance and noise during the work of the engine. Check that the oil passage hole of each hydraulic lash adjuster is clear. Camshaft/lifter prelube should be applied at the pivot pockets, roller, and the slot that contacts the valve on each rocker arm also engine oil should must be used on the bores of hydraulic lash adjusters before putting them on the cylinder head. Place the rocker arms onto the lash adjusters after that, flip over the process of uninstallation to reinstall the rocker arms. Always ensure that you change the oil of your car and also fit in a new oil filter before you start the engine.
