REPLACING/TENSIONING DRIVE BELT
If the drive belt needs tensioning, the belt should be adjusted so when pressure is
applied in the centre, there is approximately 1/2” slack. See Fig.8.
1) To install a new belt, remove belt guard. Loosen engine mount bolts and slide engine
towards the pump, remove belt.
2) Install proper replacement belt, slide engine away from pump to provide
recommended tension, align pulleys and fasten engine mount bolts.
3) Reinstall belt guard. Belt tension should be checked after 20 hours of operation.
Check belt tension monthly thereafter.
