How should one examine and maintain the Camshaft and Camshaft Bearing in V8 engine on Chevrolet Caprice?

Examine the bearing surfaces and the surfaces of the cam lobes for surface scratches; very shallow scratches can be removed with fine emery cloth or an oil stone, while any deep scoring will require a new camshaft. Mount the camshaft on V-blocks and use a dial gauge to measure lobe lift and run-out, rejecting any camshaft that does not meet the specified limits. Measure the journal diameters with a micrometer and reject any camshaft that does not meet the specified limits. If the bearings are worn, they can be extracted using a suitable tool, such as GM tool set No. J-6098, noting that it will be necessary to drive out the camshaft rear plug from the block. New bearings are installed with the same tool set, ensuring the cam bearing oil holes are aligned correctly: for a small V8, the No. 1 bearing hole should have oil holes equidistant from the 6 o'clock position, while the No. 2 through No. 4 bearing oil holes should be positioned at 5 o'clock, and the No. 5 bearing oil hole at the 12 o'clock position; for a Mark IV V8, the No. 1 through No. 4 oil holes must align with the oil holes in the cam bearing bore, and the No. 5 bearing bore should be at or near the 6 o'clock position. After installing new bearings, install a new camshaft rear plug flush 1/32 inch below and parallel to the rear surface of the block.

Chevrolet Caprice Camshaft Bearing

The Chevrolet Caprice Camshaft Bearing maintains the valve timing heart of the engine turning smoothly by providing the camshaft with a low friction oil cushioned cradle. Inside the V8 block, the Chevrolet design mounts this Camshaft Bearing in the form of a plain cylindrical case pressed into a precision machined bore. Once the engine oil is pumped through its aligned holes, it floats the spinning shaft on a microscopic film that prevents metal-to-metal grating. Like the main and rod inserts, each Camshaft Bearing depends on good oil clearance, typically just a couple thousandths of an inch, so that the shaft can glide without wobble or seizure. Two basic families of materials have emerged over the generations, bi-metal and tri-metal. Bi-metal designs typically consist of an aluminum alloy lining over a steel backbone, which is often reinforced with silicone to increase hardness and resistance to scuffing. Tri-metal versions sandwich a copper layer and a soft lead-tin overlay between the steel core, contributing fatigue strength plus embedability to capture dirt before it scars the journal. Regardless of type, slight built-in crush ensures that when the Camshaft Bearing is installed, it locks tight and will not spin. Over the years, Chevrolet paired each Caprice engine variant with the style that optimal balances durability, quietness, and high-rpm stability. Keeping the Caprice running strong requires a perfect Camshaft Bearing to support the rhythm of its camshaft.

Each OEM Chevrolet Caprice 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.

Q: How should one examine and maintain the Camshaft and Camshaft Bearing in V8 engine on Chevrolet Caprice?
A:

Mount the camshaft on V-blocks and use a dial gauge to measure lobe lift and run-out, rejecting any camshaft that does not meet the specified limits. Measure the journal diameters with a micrometer and reject any camshaft that does not meet the specified limits. If the bearings are worn, they can be extracted using a suitable tool, such as GM tool set No. J-6098, noting that it will be necessary to drive out the camshaft rear plug from the block. New bearings are installed with the same tool set, ensuring the cam bearing oil holes are aligned correctly: for a small V8, the No. 1 bearing hole should have oil holes equidistant from the 6 o'clock position, while the No. 2 through No. 4 bearing oil holes should be positioned at 5 o'clock, and the No. 5 bearing oil hole at the 12 o'clock position; for a Mark IV V8, the No. 1 through No. 4 oil holes must align with the oil holes in the cam bearing bore, and the No. 5 bearing bore should be at or near the 6 o'clock position. After installing new bearings, install a new camshaft rear plug flush 1/32 inch below and parallel to the rear surface of the block.
