CHANGING TRANSMISSION OIL
1. Remove the top and rear cover
plates on drive housing. It is
not necessary to remove the
bottom cover plate that attaches
to the lubricator
guard. (Fig.1)
2. Place clean rags or paper towels
between the belt and
transmission to catch any oil you
may spill.
(Fig 2.)
3. Locate a fill/drain plug and rotate
that plug to 12 o’clock and remove
it using a 1/8” hex bit socket.
Remove the second plug which
will be at the six o’clock position to
drain the oil. Both plugs have to
be removed for the oil to drain.
(Fig 3.)
4. Using a cut off water bottle, drain
the oil. Reinstall one of the drain
plugs. (Fig. 4.)
5. Fill the transmission with the
supplied syringe and 1.5 oz of
Mobil 1 4T 10W-40 Racing Oil
and install the second drain plug.
Change the oil every 100 hours
when you service the sprocket
shaft bearings and u-joints.
(Fig. 5)
6. Reinstall the covers using a good
grade RTV silicone on the back
cover. (Fig. 6)
7. After running your engine for the
first time after sealing the lower cover plates, remove the frame drain
plug next to the shaft housing to
check for any water leakage. If any
water come out of the drain plug, you
need to remove the lower cover plates
and re-seal it.
100 hours is the recommended oil change interval for the transmission under
normal conditions. If your engine is being used excessively in reverse you
should change the oil every 50 hours.
