Installation of Cog Belt
Installation of a new cog belt is essentially the same as the
steps outlined above, but in reverse order.
special attention to the re-installation of the taper lock system:
1. Thoroughly clean the jackshaft and sprocket bore.
2. Align the 28-tooth sprocket and taper lock flush with
the end of the jackshaft.
3. Applying Loctite 243, install the two installation set
screws into position 1 or 3.
4. Torque the two set screws to 14 N-m (125 lbf-in)
5. Tap the taper-lock face several times in the shaded
region with a steel punch and re-tighten the
setscrews.
6. Tap again and re-torque to 14 N-m (125 lbf-in).
Loctite 243 must be used for both installation setscrews
to prevent them from loosening under use. Failure to do
so could result in personal injury.
Hand-tighten the tensioner sprocket bolt (Ref. No. 9 in the
exploded view) and then proceed to re-apply tension to the
system by tightening the tensioning bolt.
When tensioned properly, the secondary transmission system
must have a deflection of 7.3 mm (0.288") under a load of 6.44
kg (14.2 lbs) applied midspan between the upper most and
lowest cog sprockets.
special tensioning tool P/N 414348200. The picture at the right
demonstrates how to use a straightedge as a reference when
verifying this value and also where the measurement should be
taken.
Failure to provide or verify the correct tension in the
secondary transmission system could lead to premature
belt and/or component failure.
One must pay
WARNING
This tension must be verified using
CAUTION
