It may be necessary to open Timing Belt Reverse Unit 8 40 R25 in order to
insert or replace the Timing Belt in it. To do this, remove all the screws.
Never use a screwdriver or similar tool to prise open the casing of Timing-Belt
Reverse Unit 8 40 R25 at its joins, as you may unintentionally break off the belt
cover.
Separate the two halves of the casing by gently tapping the hub of the timing
pulley (use plastic punches). Once the casing is open, thread the Timing Belt
through and then close Timing Belt Reverse Unit 8 40 R25 again.
All the cut edges of the profile that face the Timing Belt must be chamfered to
prevent irregular running caused by the belt getting snagged or damaged.
When feeding the Timing Belt back through the inside of profiles, ensure that
the profile edges facing the back of the belt have been rounded.
