APPENDIX B (;>0 SMALL BLOCK CHEVROLET CAMSHAFPT INSTALLATION INSTRUCTIONS 1. Prepare a clean work area and assemble the tools needed for the camshaft installation. 2. Disconnect the battery ground cable and remove the air cleaner assembly. i 1 I 3. Drain the radiator and engine oil. l 4. Disconnect the upper radiator and heater hoses at the intake manifold. 5. Disconnect the crankcase ventilation hoses as required. 6. Disconnect the fuel line, choke cable, accelerator?linkage, and transmission downshift cable (on automatics) at the carburetor. 7. Disconnect the vacuum hosesand electrical connections at the carburetor. j | 8. BDBDisconnect the power brake hose at the carburetor or intake manifold, if applicable. | 9. Disconnect the temperature sendlng switch and the coolant temperature sensor wires. | I 10. Remove the distributor cap and scrlbe the rotor position relative to the distributor body. : 11. Remove the distributor. 12. As required, remove the oil filler bracket, air cleaner bracket, air conditioner compressor bracket, alternator bracket, and accelerator bellcrank 1 — 1 13. Remove the manifold—to—head attaching bolts then remove the manifold and carburetor as an assembly. 14. If the manifold is to be replaced, transfer the carburetor (and mounting studs) water outlet and thermostat (use a new gasket), heater hose adapter, EGR valve (use new gasket) and, if applicable TVS switch and choke coil . 15. Remove the valve covers. 16. Loosen the rocker arm adjusting nut so the pushrod can be removed. 17. Once the pushrods have been rémoved, remove the valve lifters. 18 , Remove the fan, pulley, and belt. Remoave any power steering and/or AIR pump drive belts. Remove any braces for these pumps which will interfere with cover removal and position the pumps out of the way.

19. Remove the water pump. 20. Remove the crankshaft pulley and harmonic balancer. This allows access to the timing chain cover. Do not attempt to pry or hammer t damper off. 21. Rotate the retaining bolts, and remove the timing cover. 22. Clean the gasket surfaces on the block and front cover. 23. Use a sharp knife to trim any excess oil pan gasket material whi protrudes from the oil pan—to—engine block junction. 24. Crank the engine until the zero marks punched on the timing gear sprockets are closest to one another and in line between shaft centers. [ 25. Take out the three bolts that hold the camshaft gear to the camshaft. This gear is a light press fit and should come off easily If it does not come off readily, tap the lower edge of the sprocket lightly with a plastic mallet to dislodge it. It is located by a dowel . 26. The chain comes off with thé oamshaft gear. 27. Remove the fuel pump and pump;pushrod. 28. Install two 7/16—18 X l4in. bolts in the cam bolt holes and pull the cam from the block. 29. Inspect the old cam, lifters, timing components and distributor gear for any signs of abnormal uear. Replace all severly worn components . 30. Inspect the new camshaft. to make sure it was not damaged during shipment. Use a quality assembly lube to coat all the lobes and distributor gear. It is a good idea to coat the fuel pump lobe and bearing surfaces as well. 31. Install the two 7/16—18 x l4id. bolts in the cam bolt holes and carefully slide the camshaft into the block. Take time so as not to damage or dislodge the cam bearings in the block. 32. If your engine had a camshaft retaining plate, it should be installed at this time.. 33. Align the new camshaft so that the zero marks punched in the cam and crankshaft gear sprockets are closest to one another and in line between shaft centers. 34. Place the cam sprocket, with ifs chain mounted over it, in position on the front of the camshaft and pull up the three bolts th hold it to the camshaft. After the gear is in flace, turn the engin two full revolutiona to mukA cartain that the timing mearks are in on ns ntemicnaithn s amemmant ven ie c ceumaneimmm nem ce t

correct alignment between the shaft centers. 35. Install the pushrods between the rockér arms and the lifters. Make sure the pushrod is properly seated in the lifter and the rocker arm. 36. With the timing marks closest to one another and aligned, the engine is in the number six firing position. 37. At this point the following valves can be adjusted Exhaust Nos. 2, 5, 6, 7; Intake Nos. 3, 4, 6, 8. . 38. Adjust the valves by tightening the adjusting nut until no lash i felt in the pushrod. This is determined by checking push—rod end pla while turning the adjusting nut. When all play has been removed, tur the adjusting nut in 1 full turn. * 39. Crank the engine one full revolution (one—half revolution of thé camshaft). The timing marks on the camshaft and crankshaft gear will be aligned and furthest from one another. At this point, the remaining valves can be adjusted: Exhaust Nos. 1. 3. 4, 8; Intake Nos 1l zl 5' 7’ ' 40. Once the valves have been adjusted the camshaft 1nsta11atzon is complete and the intake manifold and other components which have been removed should be installed. 41. Apply a 1/8 in. bead of RTV Silicone sealer, G.M. 105236 or the equivalent, to the joint of the oil pan and cylinder block. 42. Install the front cover—to—oil pan seal. Lightly coat the bottom of the seal with engine oil and position over the crankshaft end. 43. Loosely install the front cover upper attaching bolts. 7 44. Press downward on the cover so that the dowels in the block are aligned with the holes in the cover. While holding the cover in position, tighten the upper attaching bolts alternately and evenly. 45. Install the remaining bolts and tighten the bolts to specification. 46. Install the torsional damper and the water pump. 47. For the other components reverse the removal procedure to install
