OVERHAUL

Note. For repair procedures not covered in this article, see ENGINE OVERHAUL PROCEDURES article in GENERAL INFORMATION.

Valve Guides

Check and service guides before servicing valve and seat. Guide replacement information not available at time of publication. If valve stem clearance is .0037" (.093 mm) or more, valve and/or guide must be repaired or replaced.

Valve Seat

Valve seat replacement information not available at time of publication. Valve seat runout should not exceed .0021" (.05 mm). Follow instructions of tool manufacturer for servicing valve seats. If seats are serviced, service or replace valves.

Valves

Check valves before servicing. Replace valves as necessary. DO NOT reface intake valves. See VALVES & VALVE SPRINGS SPECIFICATIONS table under ENGINE SPECIFICATIONS. Exhaust valve face may be machined if margin is .050" (1.25 mm) or more prior to grinding.

Piston & Rod Assembly

1. Before disassembling, mark rod and rod cap with matching cylinder number. Mark piston-to-rod relationship for reassembly reference. Notch or dot on piston top should face front of engine. Piston pin is a press fit.
