Crankcase Removing the pistons Turn the upper half-case. Mark the top of every piston with a marker NOTE pen in order to ensure the correct position is respected on reassembly. Extract the pistons moving the connecting rods up from bottom as indicated, and make attention not to damage the elastic bands.
Crankcase Cylinder revision Check to be sure that enclosures show no sign of seizures with the pistons. Check piston ovalization in the following way: A) Measure the nominal diameter of each cylinder at a distance of 20 mm from the superior edge as indicated in the figure.
Crankcase Piston-cylinder coupling The cylinder-piston groups are furnished already coupled; if there should be an exchange of cylinders and pistons between them it would be necessary to proceed surveying coupling plays. Measure the diameter of the (ND) pipe at 20 mmfrom the superior plane, as indicated on the sketch.
Crankcase Piston pin - connecting rod coupling Play between piston pin and connecting rod must be of 0,015÷0,032 mm. Maximum wear limit allowed 0,06 mm. Piston rings Verify the absence of lines and traces of shrinkage on each piston ring. Verify that the edge of the segment is well defined and free in the piston rings.

Crankcase Overhauling the crankshaft and countershaft Clean and check that the teeth of the gears of the two shafts are intact and have sharp edges. Check that there are no signs of anomalous wear and the surfaces are smooth. Overhauling the half-cases Replace the main bearings if there is any doubt as to their condition.
Crankcase REASSEMBLY Cylinder and piston assembly The ringss must be assembled on the piston with the writing “R” “RN” turned upwards and by following the outline in the figure. Assemble the internal ring on the piston. Assemble the internal ring on the piston. Assembly the pistons complete with the previouslydegreased and cleaned connecting rod.

Crankcase Insert the centering bush and lubricate the cylinder barrels with engine oil. The following tool is required to perform this operation: Piston installation device cod. 8000B7207 Position the device on the half-case as indicted, centring the blocking rings and lubricating the liners with engine oil.

Crankcase Push the pistons with connecting rods down into their respective cylinders. Insert the pistons compressing the segments manually to avoid damage. Pull the connecting rods downward until complete inserting of the pistons into the cylinder. Once inserted all the pistons, dismantle the tooland turn the half-crankcase.
Crankcase Refitting the half-cases Carefully degrease and clean from any paste residues. Fit the bearings in their respective seats (previously marked during disassembly) in the case without lubricating them. After having positioned them put oil on each bush. Oil the main, rod and countershaft bearings with engine oil.
Crankcase Lubricate journal no. 2 from both sides as it performs the function of centring the crankshaft. Fitting the crankshaft Place the crankshaft in place, bringing the connecting rods into contact. Use a feeler gauge to check that the crankshaft has end play of between 0.1 and 0.25 mm from the main journals.
Crankcase Fitting the connecting rods Tool no. 8000B7214 is required to perform this operation. Fit the tool on main journals no. 1 and no.4. Hand tighten the screws (1) of the tool to lock the crankshaft in place. Fit the bearings to the previously cleaned and degreased big ends, lubricating them with engine oil.
