COURSE OVERVIEW

This practical and highly-interactive course includes real-life case studies where participants will be engaged in a series of interactive small groups and class workshops. 

 

This course is designed to provide participants with a detailed and up-to-date overview of CFR Octane Cylinder and Crankcase Overhaul. It covers the purpose of CFR engines, ASTM D2699 and D2700 testing standards; the function of the octane cylinder and crankcase; the main components of cylinder head, crankcase and valve train and special features of CFR engines; the octane cylinder construction and function, crankcase assembly and operation; the tools, manuals, and safety procedures, preparation of cylinder disassembly and cylinder head and valve removal; the piston, ring and sleeve disassembly and cylinder inspection procedures; the sensor integrity and wiring checks, and inspecting detonation pickup hole; and the gasket and sealing surfaces and calibration considerations after reassembly. 

 

Further, the course will also discuss the crankcase disassembly preparation, crankshaft and bearing removal and connecting rod and cam mechanism removal; the inspection of crankcase components and troubleshooting common crankcase issues; cleaning and degreasing components, honing cylinder sleeve, installing new piston rings and gaskets and ensuring correct piston orientation; reinstalling sleeve and piston, valve lapping and seat adjustment; and reinstalling valve train components and torque procedures for cylinder head bolts. 

During this interactive course, participants will learn the installation of crankshaft and bearings, aligning and torquing main caps, reconnecting rods and piston alignment; the lubrication path verification, alignment and clearance verification including torque, lubrication and final checks; and the preventive maintenance best practices and troubleshooting after reassembly by identifying startup issues, unusual vibration/noise causes, detonation reading errors and root cause analysis and rectification.
