ENGINE CHECKS AND ASSEMBLY
3.3 ASSEMBLY OF COMPLETE
CRANKSHAFT
On the 250 version, if the slew bearing has been
removed from the left hand semi-axle (para. 3.2) the
new slew bearing will need to be fitted.
To do this, clamp the drive shaft of the semi-axle to
which the slew bearing is to be fitted with a vice and
using an electric hotplate, heat special tool A (code
026.14.018.00.00) to around 150°C and push it on to
the slew bearing straight away.
Hold the special tool tight to maintain good heat
transmission and put it on to the slew bearing on the
left hand semi-axle.
When all the aforementioned checks have been
carried out and the worn parts replaced, grease the
crankshaft oil seal on the right crankcase half and
couple the crankshaft to the left crankcase half. Keep
the conical part A on the crankshaft facing you. In
order to carry out this operation, you must just push
the shaft axially towards the crankcase.
Apply the two centring bushes 1 and 2.
