Remove four bolts (l) and the washers from therocker shaft.2. Remove rocker shaft (2) from the cylinderhead.3. Remove push rods (3) from the engine.INSTALL ROCKER SHAFT ANDPUSH RODS1102 & 1208-121.2.3.4.Loosen adjusting screws (1) on the rocker armsfor valve clearance. This will prevent a bentvalve or push rod at installation.Install push rods (3) as shown.Put rocker shaft (2) in position on the cylinderhead.Put 5P3931 Anti-Seize Compound on thethreads of the bolts (except the rear bolt fly-wheel end) that holds the rocker shaft in posi-tion. Install the four bolts and washers.NOTE: Make sure the rocker arms are on all of thepush rods.CAUTIONThe dowels on each end of the rocker shaftassembly must make an alignment with theholes in the cylinder head assembly. If thedowels and holes are not in alignment when therocker shaft assembly is tightened, damage tothe rocker shaft assembly will be the result.5.6.7.Tighten the bolts for the rocker shaft as follows:a)b)c)Tighten bolts in number sequence to a tor-que of 155 N·m (115 lb.ft.).Tighten bolts again in number sequence toa torque of 250 ± 17 N·m (185 ± 13lb. ft.).Tighten bolts again and for the last time innumber sequence (hand tighten only) to atorque of 250 ± 17 N·m (185 ± 13 lb. ft.).The assembled length of springs (4) at bothends of the rocker shaft must be 1.50 ± 0.25mm (.059 ± .010 in.). Remove or install thewashers behind springs to change the assem-bled length of the springs.Make adjustments until the intake valve clear-ance is 0.38 mm (.015 in.) and the exhaustvalve clearance is 0.64 mm (.025 in.). See EN-GINE VALVE LASH as shown in MAINTE-NANCE GUIDE. Tighten the locknuts for theadjusting screws to a torque of 29 ± 7 N·m (21± 5 lb. ft.).end by:a) install valve cover5-121
