Belt Maintenance

Checking the Pump Belt
Tension
Service Interval: After the first 8 hours
Every 200 hours
Check the pump belt for wear, cracking, or improper tension.
Check the tension by pressing belt at mid span between the
crankshaft and pump pulleys with 10 kg (22 lb) of force. A
new belt should deflect 12 to 15 mm (0.48 to 0.58 inch) A
used belt should deflect 14 to 16.5 mm (0.55 to 0.65 inch). If
the deflection is incorrect, refer to Belt Maintenance for the
tensioning procedure. If correct, continue operation.
Important: Improper belt tension may result in
increased steering effort.

Adjusting the Pump Drive Belt

1. Raise the bed (if so equipped) and position the safety
support on the extended lift cylinder to hold up the
bed.
2. Check the tension by pressing the belt at mid span
between the crankshaft and pump pulleys with 10 kg
(22 lb) of force. A new belt should deflect 12 to 15 mm
(0.48 to 0.58 inch) A used belt should deflect 14 to 16.5
mm (0.55 to 0.65 inch). If the deflection is incorrect,
proceed to next step. If correct, continue operation.
3. To adjust belt tension, complete the following:
A. Loosen the nuts securing the hydraulic pump to
the engine frame (Figure 56).

3. Adjust the jam nuts or ball joint until the back, rear
edge of the clutch pedal is 9.5 ± 0.3 cm (3.75 ± 0.12

when an 1.8 kg (4 lb ) force is applied to the pedal
(Figure 58).
