Changing The Planetary Gear Drive Oil; Checking The Rear Axle Lubricant - Toro 03781 Operator's Manual

5. Repeat steps 1–3 on the opposite planetary gear
assembly.
Changing the Planetary Gear
Drive Oil
Service Interval: After the first 250 hours
Every 800 hours (Or yearly, whichever comes first)
Change the oil initially after first 250 hours of operation.
Thereafter, change the oil every 800 hours, or yearly,
whichever occurs first. Use a high quality SAE 85W-140 wt.
gear lube as replacement.
1. With the machine on a level surface, position a wheel
so that one of the check plugs is at the lowest (6
o'clock) position (Figure 62).
1. Check/drain plug
2. Place a drain pan under the planetary hub, remove both
plugs and allow oil to drain.
3. Place a drain pan under the brake housing, remove the
drain plug and allow the oil to drain (Figure 63).

4. When all of the oil has drained from both locations,
re-install the plug in the brake housing.
5. Rotate the wheel until the open holes in the planetary
are at the 11 and 1 o'clock position (Figure 64).

6. Through either open hole, slowly fill the planetary
with .53-.59 liter (18–20 ounces) of high quality SAE
85W-140 wt. gear lube.
7. Re-install the plugs.
8. Repeat the procedure on the opposite planetary/brake
assembly.
Checking the Rear Axle
Lubricant
Service Interval: Every 400 hours
The rear axle is shipped from the factory filled with SAE
85W-140 wt. gear lube. Check the oil level before the engine
is first started and every 400 hours thereafter. The capacity is
80 oz. (2.4 l). Visually inspect for leaks daily.
1. Position the machine on a level surface.
2. Remove a check plug from one end of the axle (Figure
65) and make sure that the lubricant is up to the bottom
of the hole. If the level is low, remove the fill plug
(Figure 65) and add enough lubricant to bring the level
up to the bottom of the check plug holes.
