Chevrolet Colorado Rocker Shaft Spring Kit
The Chevrolet Colorado Rocker Shaft Spring Kit prevents valve train flutter by retaining control over the rocker shaft and the rated coil springs for the intake and exhaust valves to open and close at the correct times. On the overhead valve layout, the shaft mounted on top of the cylinder head lets each rocker arm pivot freely as the companion springs provide a seat force of about 70 to 90 pounds and roughly 200 pounds when fully open that hold the valves tight against the combustion chambers. The Rocker Shaft Spring Kit prevents lash growth that can pound lifters, bend pushrods, and snap rockers. It avoids valve float that could cause a valve to hit a piston at high rpm by keeping clearance in check. This protects Colorado drivers today from power loss. Chevrolet truck engines of an earlier era occasionally had individual springs with stud mounted rockers, but the Rocker Shaft Spring Kit connects the arms on one rigid bar, making the current Chevrolet Colorado more stable and durable under prolonged heat and mileage. By routinely inspecting the Rocker Shaft Spring Kit for wear, you will catch trouble early. Replacing a worn Rocker Shaft Spring Kit will bring back smooth power and guard against misfire.
Each OEM Chevrolet Colorado Rocker Shaft Spring Kit 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.
Chevrolet Colorado Rocker Shaft Spring Kit Parts Questions & Experts Answers
- Q: How can broken Rocker Shaft Spring Kit and Valve Stem Oil Seal be replaced without removing the cylinder head in V8 engine on Chevrolet Colorado?A:Valve springs and valve stem seals can be thereby changed without removing the Cylinder Head, these two components need two special tools and a compressed air supply. Start with the spark plugs and the valve covers, turn the crankshaft until the #1 piston is on the top in the compression stroke. Take off the Rocker Arms of the number 1 piston, screw an adapter in the spark plug hole and attach an airline from the source of compressed air. Put compressed air to the cylinder to close the valves and then use the shop rags to block the cylinder head holes around the valves to avoid dropping of the parts and tools in the engine. They should be tapped lightly with the palm of your hand to break the seal and then they require the use of valve spring compressor to compress the spring while the keepers can be removed by using small needle-nose pliers or by use of magnet. Take out the valve spring and retainer using strictly the pressure of air to keep the valve shut in order to prevent damaging it. Take out the old valve stem seals-take note that the intake and exhaust seals differ, secure a rubber band or tape around the top of the valve stem to prevent it from falling into the combustion chamber when you release the air pressure. Although this valve is relatively simple, there are several things you have to look at the valve stem, which should not bind in the guide. Reduce air pressure to hold the valve closed, then install the new valve stem seals up to the specified thickness, without clamping them up against their topped guide. Place the spring and retainer on the valve, press the assembly just enough to fit the keepers into place and drop a small quantity of grease if one is needed to hold the keepers into place. Pull the air hose off and remove the adapter from the spark plug hole and then follow the same procedure for all the rest of the cylinders, always sticking to the firing order and basically going through all of the puffs while bringing each of the pistons to the TDC on the compression stroke. Last, bolt on the rocker arm assemblies and the valve covers and crank the engine, inspecting for mainative oil leakage and other odd noises and should let the engine run for at least five minutes at idle and then bring up to its high end rpms.
