Note: Apply blue thread lock to all screws, balls, and threads which it be
fixed to metal-parts. For non-metal parts apply CA Glue.
PRACTISE ASSEMBLY
1.
Before assembling the cooling fan and
hub to the engine, pull the crankshaft
up and down to ascertain the degree of
movement – this is eliminated in the
following steps.
2.
Put the cooling fan on the crankshaft
and pull the crankshaft up whilst
pushing the fan down – gently tighten
the M3x12 clamp bolts.
3.
Check free play by pulling the shaft up
and down and repeat step 2 if there is
discernible movement.
4.
If the shaft has no any end-play,
moderately tighten the M3x12.
5.
Screw the starter shaft clockwise onto
the crankshaft with an 8mm. wrench –
you will need to hold the fan or
preferably lock the engine through the
back cover with a locking tool.
6.
Check there is no end float by pulling
the starter shaft up and down and
checks fan movements to exclude
binding.
REAL ASSEMBLY
Repeat above steps 106 but apply thread
lock to fan clamp bolts and step 2. Before
mounting starter shaft in step 5 apply thread
lock. Place clutch over starter shaft and rotate
it down over the fan center hub-this may be a
little tight and require drawing down with
M4x8 bolts. If all is well the clutch shoes will
lie on the fan center hub and the shoes will be
centered. Remove M4 bolts, thread lock and
then re-apply to clutch-finally insert M3x8
bolts.
NOTE
Our system was specially designed to
mount the clutch close to the engine this help
balance high rpm vibration and lowers the CG
point too.
