    Q:
    How to remove and install the camshaft and oil pump drive in V6 engine on Chevrolet Impala? Posted by Customer
    A:
    To get the engine out of the car, loose the commanding nut of the oil pump drive and pull out the clamp as well, finally, pull the oil pump drive upward and backward in order to separate from the block. However, before you even start, take out the timing chain and sprockets; and the valve lifters Next, look for the bolts on the underside of the camshaft that hold the thrust plate to the block and, finally, take out the thrust plate. Carefully, pull the camshaft out without seriously touching the bearings; this may be done by using a long bolt as a handle while supporting the shaft near the block. Post removal wash the camshaft with solvent and check the bearing journals for any sign of wear or pitting or seizure as in the event the two are seized, both the camshaft and bearings will require replacement. It is possible to reuse the camshaft if the bearing journals and camshaft lobes have not worn excessively, and if they have no discoloration or damage; use the micrometer to measure the journals and lobes. Inspect the camshaft bearings in the block for signs of wear and damage and measure the internal diameter of the bearings to arrive at the bearing oil clearance; here, if there is much clearance, new bearings or housings will be required. Camshaft bearing replacement involves the use of special tools, and therefore it is recommended that the block be taken to automotive machine shops. Ford Camshaft Installation: Prior to installation of the new camshaft, the camshaft bearing journals and the cam lobes should be liberally coated with a special lubricant, the camshaft is then inserted into the engine using a long bolt to help by placing it at the end of the block. Place the camshaft retainer plate and fasten the bolts to the prescribed tightness. Last it is essential to apply new engine oil on the gear portion of the oil pump drive before fitting it into the block place the O-ring on its shaft before final insertion of the shaft into the block with the O-ring and the gear of the oil pump drive inserted into the block until it comes in contact with its mounting boss and is fixed with the new nut and the retainer bolt.

    Q:
    How to remove the camshaft and Lash Adjuster on V8 engine on Chevrolet Tahoe? Posted by Customer
    A:
    To take off the camshaft, first disconnect the cable from the negative battery terminal and release fuel system pressure. From there on, remove; radiator, auxiliary automatic transmission fluid cooler (if equipped), power steering cooler, air conditioning condenser, valve covers, intake manifold, rocker arms, pushrods, timing chain and sprockets, and cylinder heads. Before you remove the lifters arrange to store them in a labeled container. Remove lash adjusters and camshaft retainer plate using a bolt as a handle to carefully pull out camshaft. To check out the camshaft measure lobe height and base circle for lobe lift determination; compare with specifications and replace the camshaft if necessary. Check the camshaft bearing journals for wear or damage; use a micrometer to measure them. Inspect the camshafts lobes for discoloration; score marks; chipped areas; unalike wear. Clean and inspect lash adjuster bodies for damage, wear and proper roller function. Put in place by lubricating bearing journals and lobes with assembly lube before sliding it into the engine, securing it with the Cam Thrust Plate. Install timing chain and sprockets , camshaft position sensor, lash adjusters As well as this refill cooling system, change oil, new oil filter installation precede start up-run engine process.

    Q:
    How to remove and reinstall camshafts,Lash Adjuster and Rocker Arm in six cylinder engine on Chevrolet Trailblazer? Posted by Customer
    A:
    A special camshaft holding tool Number GM# J-44221 or equivalent is necessary for this action. When the cam sprocket has been taken off, do not turn the crankshaft this may cause improper timing of the engine with consequent damages of the engine. Start by unwiring the valve cover and the spark plugs so as to be in a position to rotate the engine. Turn the engine clockwise until grooves for sprockets match with a black link on the chain; the flats at the back of the camshafts will be up if the engine is at the Top Dead Centre for cylinder number one. Take out the camshaft sprocket bolts, and then do so carefully with the sprockets of the camshafts. Make sure the camshaft caps have been scribed; if they haven't been scribed, scribe them with paint before you remove them, so that it will be easier for you to align them later. Loosen and take out the camshaft cap bolts and in slow procedures extract the camshafts with caution to ensure that each of them is not mixed up. This is a good time to lift out the rocker arms and the lash adjusters and it will be wise to ensure that set is orderly set aside to be re-fixed later. When camshafts are removed they should be cleaned with solvent and dried, Check each camshaft for; scored journals, heat discoloration, score marks, chipped areas, pitting and uneven wear, damaged sprocket locator slots and damaged threads. You can use micrometer to take measurement of bearing journals looking for elevated levels of wear or out-of-round. To replace it, the lash adjusters and rocker arms must be immersed in clean engine oil, before being placed back in their positions. Ensure that the camshaft is clean then apply some drop of clean engine oil on the camshaft before putting it on the right place on the cylinder head and then fitting the holding tool for the camshaft correctly. Replace all camshaft caps in their proper positions and tighten them using your hands, afterwards using a pattern tighten the caps to the prescribed torque. Take out the holding fixture, put the sprockets on the camshafts in the right way, and screw the bolts to the suggested level of tension. However, after removing the crankshaft pulley bolt, positioned with large breaker bar and socket on it, rotate the crankshaft 720 degrees the crankshaft twice and again examine the sprocket and chain and see to it that the darkened links lines up with the sprocket marks. Any kind of grinding or any feeling of friction when working on the crankshaft should indicate that operations have to be ceased. Finally, fit back the spark plugs and the valve cover in position.

    Q:
    How to remove the camshaft and Lash Adjuster on 4.3L V6 engine on GMC Sierra? Posted by Customer
    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.
