Change oil initially after 200 hours operation and
every 800 hours or yearly. Check oil level if external
leakage is noted. (Refer to "Before Operating"
page 19.) Use high quality SAE 85W-140 wt. gear
lube replacement.
Capacity of each hub is 16 oz.

2. Remove both plugs. Allow oil to drain from
the bottom hole into a pan.
3. Remove drain plug from bottom of hub on
other side of wheel and allow oil to drain into pan.
(Fig. 39)
4. When Gear Drive is completely drained,
reinstall plug on bottom of hub and position wheel
so holes are at 9 and 12 o'clock position. (Fig. 38
