Cleaning And Inspection; Assembly - Husqvarna 565 Workshop Manual

12.2 Cleaning and inspection

Clean all components and check the following:
1. That there is no play between the clutch shoes
and the clutch hub.
2. That there is no wear on the chain drive sprocket.
3. That the needle bearing is in good condition and that
there is no damage on the journal surface on the
crankshaft.
4. That the friction surface on the clutch drum is
intact and that the bearing surface is undamaged.
5. That the lining thickness on the clutch shoes is no
less than 3.5 mm at the most worn point. Check the
lining thickness on the clutch shoes as follows:
• Stretch out the spring with circlip pliers at the most
worn point and press it out from the clutch hub. See
figure 4.
CAUTION! The clutch springs must not
opened more than necessary. Risk of
deformation.
• Measure the thickness at the most worn point at the
clutch shoe. See figure 5.
• Replace the centrifugal clutch if the thickness is less
than 3.5 mm.
CAUTION! If any component on the
centrifugal clutch is worn or damaged,
the whole clutch must be replaced.

12.3 Assembly

When assembling the centrifugal clutch the chain brake
must be disengaged.
1. Fit the clutch hub on the crankshaft and tighten with
the clutch tool. Make sure that the text on the clutch
hub is assembled outwards. See figure 6.
NOTE! Left-hand thread. Screw in the
direction of the arrow as shown in figure 6.
2. Remove the piston stop and fit the spark plug and
spark plug cap.
3. Grease the needle bearing before fitting. Fit the
clutch drum (C) with needle bearing (D) and chain
drive sprocket (E). See figure 7.
4. Exercise care to ensure that the clutch drum and oil
pump gear fit in the cut-out in the drum. See figure 7.
5. Fit the washer and locking ring (B). See figure 2.
