Loosen the clamps (7) and remove the hoses (8) and (9) from the cylinder barrels (10) and from the alternator-side crankcase cover.
If damaged, unscrew the unions (6).
Note
The following procedure is described with the engine removed from the frame and the cylinder head removed from the engine (sect. 9 - 4.5, Removal of the cylinder heads).
Remove the gasket (11) from the horizontal thermal unit.
Remove the bushes (12).
Use the tool 88765.1523 To bring the piston of the horizontal cylinder near the tdc.
Carefully lift the cylinder barrel (10) off the crankcase, keeping it vertical.
If necessary, rock the cylinder slightly using both hands or tap its base gently with a rubber mallet. Continue to lift the cylinder until you can access the gudgeon pin (3).
Note
For better sealing the piston ring gaps should be positioned at 180 intervals.
Since insertion of piston in the barrel is a difficult operation to perform at the time of reassembly, remove the piston together with the barrel as described below.
Stuff the crankcase opening with a rag or soft paper to prevent foreign material from falling in.
Remove the circlip (2) from the gudgeon pin (3) on the clutch side.
Working from the opposite side, drive out the gudgeon pin sufficiently to release the connecting rod.
Lift the barrel-piston assembly clear of the crankcase studs. If work is to be carried out on the piston, carefully withdraw it from the cylinder.
Remove the four o-rings (a) located on the crankcase studs between the barrel and the base gasket (5).
To remove the vertical barrel-piston assembly, bring the vertical piston to tdc and proceed as for removal of the horizontal cylinder barrel.
Important
Mark the pistons to show from which cylinder they were removed: v= vertical - h= horizontal.
Reassembling the water radiator unit
The procedure is the same for both radiators.
Check the presence of clips (1) at the positions of the external coolant
radiator cover (23).
If removed, fit the front turn indicator (32) on the cover (23) and tighten the
screws (27) to 2 nm +/- 10% (sect. 3 - 3,
Frame torque settings).

Refitting the primary drive gears and checking backlash
Fully degrease the crankshaft splined end and the corresponding spline on the
primary drive gear.
Position the spacer (c) onto the crankshaft.
Fit the driving gear (b) onto the crankshaft with the oil pump drive sprocket
facing the crankcase.
Temporarily secure the gear with the was ...
