Suspension Adjustment; Electronic Fuel Injection (Efi) System - Kohler Efi Models - Ferris IS2000ZKAV3461SS Operator's Manual

5. Loosen the adjustment nut (I) to release the majority of the
belt tension. Use caution and remove the nut to completely
release the tension.
6. Remove the old belt and replace it with a new one (A). Make
sure the V-side of the belt runs in the grooves of the
crankshaft pulley and pump pulleys (B & C). The back-side
of the belt should contact the idler pulley (D) on the idler arm
(E).
7. Reinstall the spring anchor eyebolt into the anchor tab and
loosely fasten the adjustment nut. Turn the adjustment nut
until a measurement of 8-3/4" (21,2 cm) is achieved from
the outside of the spring hooks on the belt tension spring
(F). Tighten the jam nut.
8. Reinstall the clutch anchor pad to the PTO clutch and secure
with the hardware previously removed.
9. Reinstall the PTO drive belt.

Suspension Adjustment

The shock assembly (A, Figure 59) can be adjusted to vary the
amount of pre-load applied to the springs. This allows the
operator to maintain the ride height.
• Use less pre-load for light weight operators.
• Use more pre-load for heavy weight operators.
59
To adjust the spring pre-load:
1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine and engage the parking brake.
WARNING
Spring loaded components can kick back causing injury.
Use two hands when adjusting the shock springs. This will
prevent the wrench from slipping while pressure is being
applied.
2. Using the supplied spanner wrench (p/n 5022853) (B), insert
the tip of the wrench into the notch in the pre-load adjuster
(C).
While holding the wrench with both hands:
• Turn clockwise to decrease the pre-load.
• Turn counter-clockwise to increase the pre-load.
Make sure that for each pair of shocks that the left-hand and
right-hand are set to the same amount of pre-load.
NOTE: Spanner wrench is located under the seat. Rear tires
must be removed to adjust the rear suspension.
To adjust the upper mounting position (Rear
Shocks):
1. Park machine on a flat, level surface. Disengage the PTO,
stop the engine, and engage the parking brake.
2. Raise the rear of the machine and secure with jack stands.
The jack stands must be under the bumper. Chock the front
wheels to prevent the machine from rolling.
3. Position the jack under the cross member that ties the
suspension arms together and slowly raise the rear
suspension to relieve the pressure on the upper shock
mounting bolts.
4. Remove the upper shock mounting hardware and pivot the
shock to the position #2 (see Figure 59). Adjust the jack to
align the shock mounts to the shocks.
5. Remove the jack from under the suspension cross member.
6. Remove the jack stands from under the machine.
Electronic Fuel Injection (EFI) System -
Kohler EFI Models
EFI is an electronically-controlled fuel management system which
is monitored by an Electronic Control Unit (ECU). A Malfunction
Indicator Lamp (M.I.L.) will illuminate if problems or faults are
detected. Servicing by an authorized dealer is necessary.
CAUTION
Do not disconnect or reconnect ECU wiring harness connector
or any individual components with the ignition switch in the
"ON" position. This can send a damaging voltage spike through
the ECU.
Unplug harness from ECU before performing any welding on
equipment.
