Changing the Gearbox
Lubrication
Service Interval: Every 500 hours
The gearbox is filled with SAE140 gear oil or
equivalent.
1. Clean debris from the fill plug and the drain plug
to avoid contamination (
Figure 30 ).
2. Remove the fill plug to relieve trapped air.
3. Position a short drain pan under the drain plug
and remove the drain plug.
Note:
The high viscosity of cool oil extends the
drain time (approximately 30 minutes).
4. After oil is completely drained, install the drain
plug.
5. Remove the socket-head bolt on the back of
the gearbox.
6. Fill the gearbox until fluid comes out the back
hole.
7. Install the socket-head bolt on the rear of the
gearbox (
Figure 30 ).
8. Install the fill plug.
Inspecting the Belts
The drive belt(s) on the machine are durable.
However, the normal exposure to UV radiation, ozone
or incidental exposure to chemicals can deteriorate
the rubber compounding over time and lead to
premature wear or material loss (i.e. chunking).
Annual belt inspection is highly recommended for
signs of wear, excessive cushion cracks, or large
embedded debris with replacement when needed.
Adjusting the V-Belt
Tension
Service Interval: After the first 20 hours
Every 50 hours
Make sure that the belts are properly tensioned to
ensure that the machine is operating correctly and to
prevent unnecessary wear.
This machine is equipped with adjustable tension
pulleys that keep the V-belts tight. Depending on the
intensity of using the machine, the driveline could be
affected by the wear of the belts.
1. Remove the belt cover.

2. Check the tension of the V-belts by pushing
point A with a pressure of 7.5 kg (16-1/2 lb).
Proper tension of the belts allows 12.4 mm (1/2
inch) of deflection on each belt (
Figure 32 ).
Note:
If the tension is correct, install the belt
cover ( Figure 34 ).
