What are the steps involved in inspecting and replacing the camshaft and Camshaft Bearing on Chevrolet S10?

After removing the camshaft from the engine, clean it with solvent and dry it, then inspect the bearing journals for uneven wear, pitting, and evidence of seizure; if damaged, both the camshaft and bearings will need replacement. Measure the inside diameter of each camshaft bearing, taking two measurements at each bearing, and subtract the bearing journal diameters from the corresponding bearing inside diameter measurement to obtain the oil clearance; excessive clearance necessitates new bearings. Camshaft bearing replacement requires special tools and expertise, so it is advisable to take the block to an automotive machine shop. Check the camshaft lobes for heat discoloration, score marks, chipped areas, pitting, and uneven wear; if the lobes are in good condition and the lobe lift measurements are as specified, the camshaft can be reused. Good used roller lifters can be reinstalled with a new camshaft, and while the original camshaft can be used if new lifters are installed, it is recommended to replace both together, especially for high-mileage engines. For V6 engines, if the balance shaft is to be removed, the balance shaft gear bolt should be removed before the timing chain to hold the shaft while loosening the bolt. Remove the two bolts and the balance shaft retainer at the front of the block, then use a slide-hammer threaded into the front of the balance shaft to knock it out. Inspect the balance shaft and measure the bearing journal diameters; if measurements exceed specifications, replace the balance shaft, bearing, and bushing as a set. The rear bushing, similar to a camshaft bearing, must be installed by a machine shop with the proper tools and alignment. Inspect the balance shaft drive gear and the balance shaft driven gear for signs of wear, pitting, broken teeth, or rough operation, as both gears are serviced only as a set.

Chevrolet S10 Camshaft Bearing

The Chevrolet S10 Camshaft Bearing provides low friction support to the small truck camshaft, which needs precise spin to maintain valve timing to ensure smooth power delivery. This plain Camshaft Bearing nestles in a precision machined bore of the engine block, its cylindrical case pushed firmly into place to allow an oil film from the pump to separate metal surfaces and prevent wear. Bi-metal versions incorporate an aluminum alloy lining on a steel backing with optional strengthening of the aluminum lining with silicone to increase hardness and resistance to seizure. Tri-metal versions incorporate a copper intermediate layer with a lead-tin-copper top to improve strength and fatigue resistance, as well as the ability to embed stray debris. Whichever style is fitted, proper oil clearance between journal and Camshaft Bearing is also vital, typically measured between 0.001 and 0.0035 inches, as too much space causes a drop in oil pressure and too little causes scuffing. Engineers decided on this configuration for Chevrolet durability, forcing the Camshaft Bearing into the block rather than splitting it as they would with crank inserts. Each generation of the S10 is based on the precision of the oil hole alignment and a slight amount of bearing crush to lock the case tight and ensure the trusty mid-size Chevrolet workhorse, the S10, keeps its valvetrain running true with each Camshaft Bearing quietly doing its job.

Each OEM Chevrolet S10 Camshaft Bearing 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.
