Refitting

Refitting

When refitting the engine mounting on the gearbox side, to avoid creating stresses on the gearbox sealing surfaces resulting in deformation and oil leaks, strictly observe the following tightening sequence for the attachment bolts:

• Lightly tighten bolts (1) and (2) to an initial torque of 0.5 daNm;
• Lightly tighten bolts (3) and (4) to an initial torque of 0.5 daNm, then tighten to the specified torque;
• Tighten bolts (1) and (2) to the specified torque.

For the remaining refitting operations, reverse the procedure described for removal. For fitting the clutch release bearing and the bell-housing in the car, refer to the procedure for refitting the gearbox of the 1370 12v engine.

REMOVING-REFITTING DRIVE SHAFTS

To remove and refit the drive shafts, refer to the procedure described for the 1370 12v engine, with the difference that the drive shafts are secured to the gearbox-differential unit by means of retaining clamps and the tripod joint is inserted directly in the differential.

DISMANTLING

Refer to the dismantling of the drive shaft described for the 1370 12v engine, with the difference that on the 1581 engine, to minimise oil leaks, fluid-tight ball bearings have been fitted in the gaiters on the gearbox side. These are installed directly on the drive shafts. Use the general purpose puller to remove these bearings.

Position of damping weight on the right drive shaft

If interventions on the right drive shaft involve dismantling the damping weight, during reassembly refit the weight at the distance specified in the figure.

a = 290-295 mm or alternatively 292-297 mm
