ASSEMBLY OF CYLINDER HEAD (See page EM-18) NOTE: • Thoroughly clean all parts to be assembled. • Before installing the parts, apply new engine oil to all sliding and rotating surfaces. • Replace all gaskets, O-rings and oil seals with new parts. INSTALL VALVES (a) Insert valves in the cylinder head valve guides. Make sure the valves are installed in the correct order. (b) Install the valve spring seats and new seals. (c) Install springs and spring retainers on the valves. (d) Using SST, compress the valve springs and place two keepers around the valve stem. SST 09202-43013 (e) Tap the stem lightly to assure proper fit. INSPECTION OF CAMSHAFT 1. MEASURE CAMSHAFT THRUST CLEARANCE Using a dial gauge, measure the camshaft thrust clearance. Standard clearance: 0.05 — 0.25 mm (0.0020 — 0.0098 in.) Maximum clearance: 0.30 mm (0.0118 in.) If clearance is greater than maximum, replace the camshaft and/or camshaft housing.
