Workshop Manual Ed. 09-2011

Crankcase (crankcase half)

Warning: Carefully read this paragraph before starting the operation. Determine the reassembly sequence in order carry out a single

heating treatment on the crankcase halves to refit the bearings.

To detach or remove the bearings - if necessary even tapping with suitable tools - remove the reference bushings and place the crank-

case halves on a flat surface big enough to avoid damaging the sealing surfaces of the crankcase halves. To this end we recommend

using a wood plane.

Bearings and sealing rings should never be fitted without a suitable press, otherwise pay utmost attention and use other suitable tools.

When the casings reach 150 °C cold bearings fall in the relevant seats without any effort.

If the bearings are not well seated after cooling down, it is probable that they will turn in their seats upon following operation: it is thus

necessary to replace the crankcase.
