Note
Before fitting the pipes (7), it is recommended to check the presence of the o-rings (e). Lubricate them by using engine oil.
If the nipples (5) have been removed from the radiator insert a washer (6) on each nipple (5) and apply specific threadlocker on threads on the radiator side.
note
The washers (6) must be inserted on the side of the nipples (5) which represent the thread with the smaller diameter, and must be oriented with the cutting edge to the radiator.
Start the nipples (5) on the oil cooler (1) and tighten them to a torque of 23 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Lubricate the nipples threads (5) with engine oil.
Attach the hoses to the nipples (5), finger-tightening the ring nuts (f) of the hoses on the nipples.
Tighten the ring nuts (f) to a torque of 18 nm +/- 5% (sect. 3 - 3, Frame torque settings).
If the horizontal exhaust heat guard assembly was removed, on refitting insert the screw (16) with a washer (17) in heat guard (14) to join it to the exhaust protection (15), and then fit the other washer (17) with spacer (18) on the protruding end of the screw.
Note
The spacer (18) must be oriented with the collar (g) facing the heat guard (14).
Fit the heat guard (14) on the exhaust protection (15) by tightening the screw (16) to a torque of 3 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Fit the heat guard (14) and heat protection (15) assembly on the horizontal cylinder head with support (10) by tightening the screw (11) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Check that the vibration damper mounts are present on the oil cooler (2).
Fit the oil cooler (1) by inserting it first into pins (c) and (d) of the supporting bracket.
If you encounter any difficulties, apply lubricant for rubber to the pin (d).
Insert the spacer (3), the screw (4) and start the screw (4).
Position the pipes (7) in the crankcase half. Position the plate (9).
Tighten the screw (8) to the torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Tighten the screw (4) to the torque of 6 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Close the pipe grommet (11).
If previously removed, place the sensor (12) with washer (13) on cooler and tighten it to a torque of 19 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Connect the sensor (12) to the main wiring.

Refitting the exhaust system
Refit the heat guard on the manifold (10) by tightening the nuts (9) to a
torque of 10 nm +/- 10% (sect. 3 - 3, Frame
torque settings).
Position the vertical exhaust manifold (22) on the vertical cylinder head
with the gasket (23).
Tighten the fixing nuts (21) to a torque of 10 nm +/- 1 ...
Checking the camshafts and supports
Check the cam contact surfaces for scratches, grooves, steps and waving.
Worn cams are frequently the cause of poor timing, which leads to loss of engine
power.
Place the camshaft between two centres and check the run-out on the areas
indicated using two dial gauges.
