clutch and transmission.
3. Support the CRF in an upright position on a
level surface.
4. Remove the transmission oil fill cap (1), oil
check bolt (2) and sealing washer (3) from the

check bolt hole.
If no oil flows out of the oil check bolt hole,
add oil slowly through the transmission oil fill
hole until oil starts to flow out of the oil check
bolt hole.
Install the oil check bolt with the sealing
washer and transmission oil fill cap. Repeat
