[. . . ] THIS IS TO ACHIEVE A BETTER BEDDING. Refitting the cylinder - Insert the cylinder base gasket with the thickness determined above. - Using the fork support and the piston ring retaining band, refit the cylinder as shown in the figure. N. B. BEFORE FITTING THE CYLINDER, CAREFULLY BLOW OUT THE LUBRICATION DUCT AND OIL THE CYLINDER BARREL. Specific tooling 020393Y Piston fitting band 020287Y Clamp to assemble piston on cylinder ENG - 142 Carnaby 125 - 200 Engine Inspecting the cylinder head Head check - Using a trued bar and feeler gauge check that the cylinder head surface is not worn or distorted. Maximum allowable run-out: 0. 05 mm - Check that the camshaft and the rocker pin capacities exhibit no wear. - Check that the cylinder head cover surface, the intake manifold and the exhaust manifold are not worn. Standard diameter A Ø 12. 000 ÷ 12. 018 mm B Ø 20. 000 ÷ 20. 021 mm C Ø 37. 000 ÷ 37. 025 mm - Using a trued bar and feeler gauge check that the cylinder head surface is not worn or distorted. Maximum allowable run-out: 0. 05 mm - Check that the camshaft and the rocker pin capacities exhibit no wear. - Check that the cylinder head cover surface, the intake manifold and the exhaust manifold are not worn. Characteristic ENG - 143 Engine Carnaby 125 - 200 bearing «A» Ø 12. 000 - 12. 018 mm bearing «B» Ø 20. 000 ÷ 20. 021 mm bearing «C» Ø 37. 000 - 37. 025 mm Inspecting the timing system components - Check that the guide shoe and the tensioner shoe are not worn out. - Ensure that the camshaft control pulley chain assembly and the sprocket wheel are not worn. - If you encounter wear, replace the parts or, if the chain, sprocket wheel and pulley are worn replace the whole assembly. - Remove the centre screw with the washer and the tensioner spring. Check that the one-way mechanism is not worn. - Check the condition of the tensioner spring. - If examples of wear are found, replace the whole assembly. ENG - 144 Carnaby 125 - 200 Engine Inspecting the valve sealings - Insert the valves into the cylinder head. - Alternatively check the intake and exhaust valves. - The test is carried out by filling the manifold with petrol and checking that the head does not ooze through the valves when these are just pressed with the fingers. Inspecting the valve housings - Check the width of the imprint on the valve seat«V» wear limit max. - Remove any carbon formation from the valve guides. - Measure the inside diameter of each valve guide. - Take the measurement at three different heights in the rocker arm push direction. - If the width of the impression on the valve seat or the diameter of the valve guide exceed the specified limits, replace the cylinder head. Characteristic Valve seat wear Intake guide limit accepted: 5. 022 Valve seat wear Intake guide Standard diameter: 5. 000 ÷ 5. 012 mm Valve seat wear Exhaust guide Accepted limit 5. 022 Valve seat wear Exhaust guide Standard diameter: 5. 000 ÷ 5. 012 mm ENG - 145 Engine Carnaby 125 - 200 Inspecting the valves - Measure the width of the sealing surface on the valve seats and on the valves. Sealing surface width: After use: Intake and exhaust: 1. 6 mm - If any of the sealing surfaces on the valves is wider than the specified limit or is damaged in one or more points, or curved, replace the valve with a new one. CAUTION DO NOT REVERSE THE FITTING POSITIONS OF THE VALVES (RIGHT - LEFT). Characteristic Valve wear check Standard: Intake and exhaust: 0. 99 - 1. 27 mm - Measure the diameter of the valve stems in the three positions indicated in the diagram. - Calculate the clearance between valve and valve guide. - Check that there are no signs of wear on the surface of contact with the articulated register terminal.
