INSTRUCTIONS FOR REASSEMBLY

For reassembly operations, reverse the sequence followed for disassembly, unless otherwise specified below.

Checking and adjusting valve clearance

• After refitting the camshaft measure the valve clearance as follows:

• Turn the camshaft to take the intake and exhaust valves to the closed position.

1. Check that the clearance between the lowered radius of the cam and the corresponding tappet is within the specified limits.

• If the clearance is not within the specified limits, proceed as follows:

1. Using the pressure lever no. 1.820.262.000 lower the tappet.

1. Position tool no. 1.820.261.000 directing the notches on the edge of the tappets to facilitate removal of the plate.

1. Prise and remove the tappet adjustment plate.

• Replace the removed plate by another one of suitable thickness to restore the correct valve clearance.

Checking the crankshaft end float

1. Using a dial gauge on a magnetic base, measure the crankshaft end float and check that it is within the specified limits.
