Book Excerpt: 1979-1981 Honda GL1100 Gold Wing Repair Manual ENGINE, CLUTCH AND GEARBOX

REASSEMBLING THE ENGINE/GEARBOX UNIT: REFITTING THE CLUTCH ASSEMBLY

1. Mesh the duplex oil pump drive over the sprocket on the clutch outer drum and fit the drum onto the splined clutch shaft. Refit and tighten the sprocket retaining Allen bolt and plain washer. Refit the 40 mm internal circlip into the center of the outer drum, followed by the splined washer, which fits over the clutch shaft.
2. Place the clutch center on the work surface and fit the friction plate with the smaller width over it, followed by alternate plain and friction plates, finishing with a friction plate. Note that each plate should be lightly lubricated with clean engine oil and that the double thickness damper plate must be fitted between the 4th and 5th friction plates in place of a normal plain plate. To complete the assembly, fit the pressure plate so that its bosses protrude fully through the corresponding holes in the clutch center.
3. The complete inner clutch assembly may now be fitted into the clutch outer drum by guiding the plate outer tongues into the slots of the drum whilst holding the assembly together by means of keeping a finger and thumb on one of the pressure plate bosses. Ensure that all the clutch plates are fully located in the outer drum and retain the inner assembly by fitting the special washer over the shaft end, followed by the slotted securing nut. The special washer must be fitted with the OUTSIDE mark outermost and the securing nut with the chamfered face inwards.
4. In order that the clutch shaft be prevented from rotating as the special nut is tightened, pressure should be applied to the plates using two or three clutch springs and bolts as described for dismantling. As before, a number of washers should take the place of the clutch lifter plate. Tighten the special nut to a torque setting of 5.5 - 6.5 kgt m (40-47 lbf ft).

COOLING SYSTEM

COOLING SYSTEM: FLUSHING

1. After extended service the cooling system will slowly lose efficiency, due to a buildup of scale, deposits from the water and other foreign matter which will adhere to the internal surfaces of the radiator and water channels. This will be particularly so if distilled water has not been used at all times. Removal of the deposits can be carried out easily, using a suitable flushing agent in the following manner.
2. After allowing the cooling system to drain, refit the drain plug and refill the system with clean water and a quantity of flushing agent. Any proprietary flushing agent in either liquid or dry form may be used, providing that it is recommended for us with aluminum engines. NEVER use a compound suitable for iron engines as it will react violently with the aluminum alloy. The manufacturer of the flushing agent will give instructions as to the quantity to be used.
3. Run the engine for ten minutes at operating temperatures and drain the system. Repeat the procedure TWICE and then again using only clean cold water. Finally, refill the system as described in the following Section.

COOLING SYSTEM: FILLING

1. Before filling the system, check that the sealing washer on the drain plug is in good condition and renewed if necessary. Fit and tighten the drain plug and check and tighten all the hose clips.
2. Fill the system slowly to reduce the amount of air which will be trapped in the water jacket.
