Remove And Install Rocker Shaft Assemblies And Push Rods
Start By:a. remove valve covers and spark plugs 1. Remove bolts (1), and lift shaft (2) and the rocker arms off the valve cover base and the push rods. 2. Remove push rods (4) from the valve lifters and valve cover base. Put identification marks on the push rods as to their location in the engine.3. Remove bridge assemblies (3) from the dowels. The following steps are for the installation of the rocker shaft assemblies and push rods.4. Loosen the adjustment nuts and screws on valve bridges (3).5. Put clean engine oil on the bridge dowels, the inside diameter of valve bridges (3) and on the top pad of the valve bridge. Install valve bridges (3) on the bridge dowels as shown.6. While valve bridges (3) are pushed straight down with a force of 25 20 N (5.6 4.5 lb.) on the top contact surface, turn the adjustment screw until it makes contact with the valve stem. Turn the adjustment screw another 20° to 30°. This will straighten the dowel in the guide and compensate for the clearance (slack) in the threads.7. Hold the adjustment screw in position and tighten the nut around the adjustment screw to a torque of 30 4 N m (22 3 lb.ft.).8. Apply 8T2998 Camshaft Lubricant on both ends of push rods (4) and position the push rods in the valve lifters and valve cover.
Make sure the crankshaft and camshafts are in time with each other and that the adjustment screws in the rocker arms are turned all the way out before the rocker shaft bolts are tightened or damage to the valves or pistons can be the result. See Install Camshafts for the procedure to time the engine.
9. Put the rocker arms and shaft (2) in position on the valve cover. Make sure the rocker shafts and push rods are in alignment and install bolts (1) to hold shaft (2). Tighten bolts (1) to a torque of 135 15 N m (100 11 lb.ft.).10. Make an adjustment of the valves to have a clearance of 0.51 mm (.020 in.) for intake, and 1.02 mm (.040 in.) for exhaust. See Valve Clearance Setting in Testing and Adjusting for the complete procedure.End By:a. install valve covers and spark plugs
