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 (3) 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 (4) from the dowels.Install Rocker Shaft Assemblies And Push Rods
1. Loosen the adjustment nuts and screws (1) on valve bridges (2).2. Put clean engine oil on the bridge dowels, the inside diameter of valve bridges (2) and on the top pad of the valve bridge. Install valve bridges (2) on the bridge dowels as shown.3. While bridges (2) are pushed straight down with a force of 5 to 45 N (1 to 10 lb.) on the top contact surface, turn adjustment screw (1) until it makes contact with the valve stem. Turn screw (1) another 1/31/2 20° to 30° ( to hex on nut). This will straighten the dowel in the guide and compensate for clearance (slack) in the threads.4. Hold adjustment screw (1) in position, and tighten the nut around screw (1) to a torque of 30 4 N m (22 3 lb.ft.).
Install the push rods in their original location in the engine.
5. Put clean engine oil on the push rods and in the lifter cups for the push rods. Put push rods (3) in position in the valve lifters.
Make sure the crankshaft and camshafts are in time with each other and that adjustment screws (5) 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.
6. Put the rocker arms and shaft (4) in position on the valve cover. Make sure the rocker shafts and push rods are in alignment, and install the bolts to hold shaft (4).7. Make an adjustment of the valves to have a clearance of 0.38 mm (.015 in.) for intake and 0.76 mm (.030 in.) for exhaust. See the topic, Valve Clearance Setting in Testing And Adjusting module, for the complete procedure.End By:a. install valve coversDisassemble Rocker Shaft Assemblies
Start By:a. remove rocker shaft assemblies and push rods 1. Slide shaft assembly (1) out of rocker arms (2). If necessary, remove the dowel from shaft assembly (1). 2. Remove adjustment screw (4) and the nut from rocker arm (2).3. Use a hammer and punch to push socket (3) out of rocker arm (2). 4. Remove the ring that holds button (5) in socket (3), and remove the button from the socket. 5. Use tool group (A) to remove bearing (6) from rocker arm (2).6. Do Steps 2 through 5 for the other two rocker arms.Assemble Rocker Shaft Assemblies
1. Align the oil hole (slot) in the bearing with the oil passage in rocker arm (1). Use tool group (A) to install the bearing in rocker arm (1) with the joint in the bearing toward the top of the rocker arm. The bore in the bearing must be 37.140 0.015 mm (1.4622 .0006 in.) after assembly. 2. Align the scribe mark on socket (2) with the mark on rocker arm (1), and install the socket in the rocker arm.3. Put button (3) in socket (2), and install ring (4) to hold the unit together. 4. Install adjustment screw (5) and nut (6) on rocker arm (1).5. Do Steps 1 through 4 for the other two rocker arms. 6. If the dowel was removed from shaft assembly (7), install the new dowel in the shaft until it is 6.00 mm (.236 in.) above the surface of the shaft.7. Put clean engine oil on the rocker arm bearings and shaft assembly (7). Install rocker arms (1) on shaft assembly (7).End By:a. install rocker shaft assemblies and push rods
