1. Remove bolts (1) and lift rocker 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. 3. Remove bridge assemblies (4) from the dowels.Install Rocker Shafts & 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 25 20 N (5.6 4.5 lb) on the top contact surface, turn adjustment screw (1) until it makes contact with the valve stem. Turn screw (1) another 20 to 30 degrees. This will straighten the dowel in the guide and make compensation 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). 5. Put push rods (3) in position in the valve lifters and valve cover base. Put clean engine oil on the top and bottom of the push rods and on top of the contact surfaces of the valve bridges.
Make sure the crankshaft and camshaft are in time with each other and that adjustment screws (5) are turned all the way out before the rocker shaft bolts are tightened of 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 rocker 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 rocker shaft (4).7. Make an adjustment of the valves to have a clearance of 0.40 mm (.016 in) for the inlet and 0.76 mm (.030 in) for the exhaust. See the topic "Valve Clearance Setting" in the Testing & Adjusting manual for the complete procedure.End By:a. install valve coversDisassemble Rocker Shaft Assemblies
Start By:a. remove rocker shafts 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 Tooling (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. Make an alignment of the oil hole (slot) in the bearing with the oil passage in rocker arm (1). Use Tooling (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. make an alignment of 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 7.7 0.5 mm (.303 .020 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 shafts and push rods
