9 ADJUSTMENTS

9.1 SPEED LIMITER.

The transport and mow speeds of the machine are
factory set and should not be altered. Ransomes
Jacobsen Limited cannot be held responsible for
loss of performance or machine damage if these
speeds are altered.
9.2 ALTERNATOR/WATER PUMP - DIESEL
The water pump belt is adjusted so that it has
sufficient tension to avoid undue stress on alternator
bearings but does not slip on the alternator pulley.
Use the following procedure to check the belt
tension at the mid-point of the belt between crank
shaft and alternator pulleys.
1. Loosen alternator bolt (Diesel A / LPG 1 & 2)
and pivot bolt on the underside of the Alternator.
2. Move the alternator to tighten or loosen the belt
so that a deflection of 7 to 9 mm is achieved at
the mid-span with a load 10Kgf (98N/22lbs) for
a new belt, and 8 to 10mm for a used belt.
3. Re-tighten bolts .
9.3 COOLING FAN BELT - DIESEL
The cooling fan belt is adjusted so that it has some
slack to avoid undue stress on the water pump
bearing but does not slip on the pulley. Use the
following procedure to check the belt tension in the
span between the fan and tension pulleys.
1. Loosen tensioner bolt (C)
2. Release lock nut on bolt (B)
3. Adjust bolt (B) to obtain a belt deflection of 10 to
11mm with a load 10Kgf (98N/22lbs) for a new
belt, and 11 to 11.5mm for a used belt.
4. Re-tighten bolt (C)
