Steps 6 to 8 are identical with those in "CHANGE OIL IN
TRANSMISSION CASE (PAGE 4-67)".
NOTICE
Do not start up the engine without the transmission being filled with oil. If
the engine is started up while the transmission is empty or short of oil, the
transmission hydraulic pump will suffer damage.
6. Before starting the engine, add 90 liters (23.78 US gal) of oil through oil filler port (F).
When oil is added, the level will temporarily go above the oil level on sight gauge (G), but this does not indicate
any abnormality.
7. Start the engine and run at low idling.
8. Add oil through oil filler port (F) until the oil level is between the H and L marks on sight gauge (G).
Make sure that the oil level in the brake oil tank does not go down below the mark in the sight gauge (H) while
the engine is running at low idling. If the oil level goes down below (H) mark, stop the engine and raise the oil
level in the brake oil tank.
REMARK
Steps 9 through 11 are identical with those in "CHANGE OIL IN TRANSMISSION CASE (PAGE 4-67)".
9. Carry out the warming-up operation of the engine until the torque converter oil temperature gauge goes above
40°.
10. When the torque converter oil temperature gauge rises to 40°, bleed the air from the brakes.
Front brake:See "BLEED AIR FROM FRONT BRAKE (PAGE 4-33)".
Center brake:See "BLEED AIR FROM CENTER BRAKE (PAGE 4-34)".
NOTICE
Do not attempt to use the oil drained during air bleeding again. Such a practice can cause damage on the machine's tool and
equipment.
Make sure that the oil level in the brake oil tank does not go down below (H) level in the sight gauge during air bleeding. If it
does, the brake oil pump could be damaged.
