How to remove and install Timing Chain and Variable Timing Sprocket in V8 engine on Chevrolet El Camino?

If the engine has been removed from the car, disregard the following steps which do not apply. Begin by removing the torsional damper and crankcase. Turn the engine until the marks on the camshaft and crankshaft sprockets are in alignment, ensuring not to remove either sprocket or the chain until this is completed. Next, remove the three camshaft sprocket retaining bolts and lift the camshaft sprocket and timing chain together off the front of the engine, using a soft-faced mallet if necessary. If it becomes necessary to remove the crankcase sprocket, it can be pulled from the crankshaft using a puller designed for this purpose. Install the crankshaft sprocket to the crankshaft using a bolt and washer from the puller set. Then, install the timing chain over the camshaft sprocket, allowing slack in the chain to hang down over the crankshaft sprocket. With the timing marks aligned, slip the chain over the crankshaft sprocket and draw the camshaft sprocket into place with the three retaining bolts, avoiding any hammering or driving that could dislodge the welsh plug at the rear of the engine. After ensuring that the timing marks on both sprockets are perfectly aligned, if they are not, remove the camshaft sprocket and adjust until the marks align. Finally, lubricate the chain with engine oil and install the remaining components in the reverse order of removal.

Chevrolet El Camino Variable Timing Sprocket

The Chevrolet El Camino Variable Timing Sprocket lets the iconic coupe-utility squeeze more power and flexibility from its small block by precisely matching cam rotation to crankshaft position. Unlike fixed gears, the Variable Timing Sprocket teams up with the timing chain, tensioners and guides as a complete set, allowing accurate alignment of cam and crank marks during standard assembly yet also providing built-in adjustment points for performance tuning. Chevrolet equips select models with multiple keyways in the crank gear or offset slots in the cam gear so the Variable Timing Sprocket can be advanced or retarded a few degrees, a small change that can shift torque toward low rpm or push horsepower higher in the rev range. For everyday drivers, lining up factory marks on the Variable Timing Sprocket keeps the El Camino smooth and reliable. But hot-rodders break out a degree wheel to nail cam timing within a fraction of a degree and stop the fifty-horsepower losses that sloppy alignment can cause. Because wear in a chain set affects accuracy, each Variable Timing Sprocket swap should occur alongside fresh chains, guides and tensioners, preserving the crisp synchronization that lets the Chevrolet V8 in an El Camino pull hard from idle to top end.

Each OEM Chevrolet El Camino Variable Timing Sprocket 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.
