Tensionamento cinghia distribuzione

Tensionamento cinghia distribuzione

1. Complete the fitting of the belt in the following order: 1. Crankshaft gear (already fitted) - 2. Oil pump gear - 3. Fixed pulley - 4. Timing pulley, inlet side - 5. Timing pulley, exhaust side - 6. Automatic tensioner.
2. Remove the bolt (1) to allow tool 1860876000 for tensioning the timing belt to be positioned.
3. Acting on tool 1860876000, place the belt tensioner in the maximum tension position, then lock the tensioner nut. Remove the dial gauge and tighten the camshaft pullies to a torque of 11.5 daNm using tool 1860885000 on support 1860831001.
4. Remove tools 1860874000; rotate the crankshaft through two revolutions in the direction of rotation, loosen the nut locking the tensioner and, using a special spanner on the belt tensioner, position reference (1) in line with reference (2), then tighten the belt tensioner lock nut to a torque of 2.3 daNm.

Fit the belt with the camshaft pullies facing towards the right in order to recover any necessary clearance for fitting the belt perfectly on the actual pullies, ensuring the correct tension in the section of the belt already fitted.

As a further check, refit the dial gauge, detect T.D.C. and check that tools 1860874000 fit on the camshafts, then refit the components removed previously.
