1. Vent/Fill plug 3. Drain plug
2. Check plug
4. Ensure that oil is up to the bottom of the check
plug hole in the gearbox (
Figure 46 ).
5. If the oil level is low, remove the vent/fill plug
from top of the gearbox and add the specified
gear oil as required.
6. Install the plugs.
Changing the Gearbox Oil
Service Interval: After the first 50 hours
Every 500 hours
1. Clean debris from vent/fill plug and drain plug to
avoid contamination (
Figure 46 ).
2. Remove the vent/fill plug to relieve air draw.
3. Position a drain pan under the drain plug and
remove the plug.
Note:
The high viscosity of cool oil extends the
drain time (approximately 30 minutes).
4. After the oil is completely drained, install the
drain plug.
5. Fill the gearbox with the specified gear oil.
Use the chart that follows to determine the
gearbox-oil capacity.
Model Gearbox-Oil Capacity
SR54 1.9 L (2 US qt)
SR54-S 1.9 L (2 US qt)
Model Gearbox-Oil Capacity
SR70 1.9 L (2 US qt)
SR70-S 1.9 L (2 US qt)
SR72 3.8 L (4 US qt)
6. Install the vent/fill plug.
7. Check the oil level and add oil as needed.
Inspecting/Adjusting the
Drive Chain
Service Interval: Before each use or daily and adjust
the tension as needed.
•
Check the drive chain for wear and damage.
Replace a worn of damage drive chain.
•
Check the drive chain tension.
The chain should move approximately 13 mm (1/2
inch) of overall deflection, or 6 mm (1/4 inch) in
each direction. If the chain tension is more than or
less than 13 mm (1/2 inch) of overall deflection,
adjust the tension; refer to
Adjusting the Drive
Chain (page 33) .
•
Check the drive chain for rust and freedom of
movement. If the chain is rusty and stiff, lubricate
it; refer to
Lubricating the Drive Chain (page 34) .
Adjusting the Drive Chain
Chain tension can be adjusted by slightly loosening
the main jam nut and tightening the jam rod to desired
position (
Figure 47 or Figure 48 ). Do not adjust the
chain tension when the chain is hot or warm.
