15. Apply a thin film of clean Mobilfluid 424 ® Tractor
Hydraulic Fluid (ISO 46) to the new transmission
filter gasket. Install the new filter and torque to 27-34
Nm (20-25 lb-ft).
16. Transmission oil may be added through the dipstick
tube (1). Remove the dipstick and add approximately
11,4 liters (3 Gallons) of Mobilfluid 424
® Tractor
Hydraulic Fluid (ISO 46). Check the oil level by
taking intermittent dipstick readings as outlined in
the appropriate Operator & Safety Manual. DO NOT
overfill. Reinstall the dipstick when finished.
17. Transmission Transfer Case (Drop Box) oil may be
added through the fill plug (2). Remove the fill plug
and add approximately 1,4 liters (1.5 Quart) of
Mobilfluid 424
® Tractor Hydraulic Fluid (ISO 46).
Check the oil level at sight gauge (3) directly below
the fill plug.
18. Install the engine cover and belly pan.
19. Install and connect the battery cables on the battery.
6.6.4 After Transmission Service or
Replacement
In general:
1. Check the transmission oil level and add oil as
required.
2. Install a new transmission filter.
3. Check the torque on the drive shaft yoke capscrews.
4. Wear suitable eye protection. When an overhauled
or repaired transmission is installed, thoroughly
clean the oil cooler lines to and from the transmission.
5. Drain and flush the entire system.
6. Disconnect and clean all transmission cooler hoses.
When possible, remove transmission lines from the
machine for cleaning.
7. Thoroughly clean transmission filter screens and
cases, and replace transmission filter elements.
8. Back flush the transmission oil cooler portion of the
radiator or the oil cooler (located behind the radiator)
with oil and compressed air until all foreign material
is removed. Flushing in the direction of normal oil
flow does not adequately clean the cooler. If needed,
remove the radiator or oil cooler from the machine.
9. Reassemble all components and fill the transmission
with clean, fresh Mobilfluid 424 ® Tractor Hydraulic
Fluid (ISO 46) through the dipstick tube opening (1).
Remove the dipstick and fill with approximately
11,4 liters (3 gallons) of Mobilfluid 424
® Tractor
Hydraulic Fluid (ISO 46). Check the level by taking
intermittent dipstick readings as outlined in the
appropriate Operator & Safety Manual. DO NOT
overfill. Reinstall the dipstick when finished.
10. Transmission Transfer Case (Drop Box) oil may be
added through the fill plug (2). Remove the fill plug
and add approximately 1,4 liters (1.5 Quart) of
Mobilfluid 424
® Tractor Hydraulic Fluid (ISO 46).
Check the oil level at sight gauge (3) directly below
the fill plug.
11. Run the engine for two minutes at idle to help prime the
torque converter and the transmission oil lines.
12. Recheck the level of the fluid in the transmission with
the engine running at idle.
13. Add Mobilfluid 424 ® Tractor Hydraulic Fluid (ISO 46)
as necessary to bring the fluid level up until it
reaches the FULL mark on the dipstick. Recheck the
oil level when it reaches operating temperature
83-94° C (180-200° F).
14. Recheck all drain plugs, lines, connections, etc., for
leaks, and tighten where necessary.
