Inspection Of Crankshaft - Husqvarna 165 R Workshop Manual

Inspection of crankshaft

The crankshaft cannot be reconditioned and must be re-
placed by a new one in the event of defects or damage.
Some crankshafts display slight blue discolouration of
the webs round the crank pin. This is perfectly normal
and is the result of heat treatment round the crank pin
hole. Inspect the connecting-rod big-end if binding
marks and discolouration of the sides are in evidence,
the crankshaft must be replaced.
The connecting-rod should display no perceptible radial
(up and down) play while axial play should be 1.2-1.6
mm.
Mount the ball bearings on the ends of the crankshaft.
This will be facilitated by carefully heating the bearings
to about 80º C before feting them on the crankshaft. Tap
the bearings down against the shoulder, using sealing
ring assembly sleeve No. 502 50 79-01.

Heat the magneto side crankcase half to about 130°C.
Fit the crankshaft with ball bearings in the bearing seat.
Check that the correct crankshaft Journal is mounted and
that the ball bearing abuts against the bottom of the bearing
seat.
Smear a little grease on the magneto side sealing surface
to keep the gasket. In position Fit a new gasket. Heat the
drive side crankcase half in the same manner as before
and press it down over the crankshaft and the magneto
side.
Check that the locating pins mate correctly and that the
gasket is not dislodged.
Fit the crankcase screws in place and tighten them
alternately as shown in Fig. 7:9. Cut away any surplus
gasket material.
