Engine Removal/Installation Service Information; Engine Removal/Installation Torque Values - Honda GL1800 Service Manual

SERVICE INFORMATION
GENERAL
• A floor jack or other adjustable support is required to support and maneuver the engine.
• A hoist or equivalent is required to support the motorcycle when removing and installing the engine.
Supporting the engine using the engine oil filter will damage the engine.
• When removing/installing the engine, tape the frame around the engine beforehand for frame protection.
• The following components require engine removal for servicing.
– oil pump (section 4)
– intake manifold (section 5)
– primary gears/output shaft (section 10)
– piston/connecting rod (section 11)
– crankcase, crankshaft (section 11)
– transmission (including gearshift spindle: section 11)
– reverse shifter/shift drum lock arm (section 18)
• The following components can be serviced with the engine in the frame.
– throttle body, injector (section 5)
– water pump/thermostat (section 6)
– cylinder head/valves (section 8)
– clutch (section 9)
– gearshift linkage (exception of the gearshift spindle: section 10)
– alternator (section 16)
– ignition pulse generator (section 17)
– starter/reverse motor (section 18)
• When using the lock nut wrench, use a deflecting beam type torque wrench 20-inches long. The lock nut wrench
increases the torque wrench's leverage, so the torque wrench reading will be less than the torque actually applied to the
lock nut. The specification given on the next page is the actual torque applied to the lock nut, not the reading on the
torque wrench when used with the lock nut wrench. The procedure later in the text gives both actual and indicated
torque readings.
