Reduction Systems (if equipped)
Some engines are equipped with a gear
reduction system. Follow maintenance and oil
change information specifi ed in this section and
maintenance schedule.
2:1 Reduction System (CH270)
This reduction system is lubricated by engine
100
crankcase oil. No special maintenance or
40
service is necessary. Check and maintain
engine oil level as outlined in Check Oil Level.
2:1 with Clutch Reduction System (CH270,
CH395, CH440)
This reduction system uses a clutch assembly
and chain and sprocket drive system,
independent of, and separated from main
crankcase lubrication. Check and maintain oil
level using dipstick in gear box case. Change
reduction system oil at interval in maintenance
schedule. Use 20W-40 or 20W-50 oil in this
gear box case. Oil capacity of this gear box is
0.5 L (0.52 U.S. qt.).
1. Drain old oil out through oil drain plug of gear
box cover, tip engine as required. Reinstall
drain plug and tighten securely.
2. Engine must be level. Add new 20W-40 or
20W-50 oil through oil dipstick hole on top of
gear box case until oil level is up to bottom of
the mark on the oil dipstick in gear box case.
Reinstall dipstick securely into gear box
cover.
6:1 Reduction System (CH270)
This reduction system uses an internal pinion
and ring gear system, independent of, and
separated from main crankcase lubrication.
Check and maintain oil level using oil level/
drain plug hole in gear box case. Change
reduction system oil at interval in maintenance
schedule. Oil capacity of this gear box is 0.12 L
(0.13 U.S. qt.).
1. Drain old oil out through oil level/drain plug,
tip engine as required.
2. Engine must be level. Add new oil through oil
fi ll plug hole on top until oil level is up to
bottom of oil level/drain plug hole. Reinstall
both plugs and tighten securely.
6:1 Reduction System (CH395, CH440)
This reduction system is lubricated by engine
crankcase oil. No special maintenance or
service is necessary. Check and maintain
engine oil level as outlined in Check Oil Level.
