Case Tractor FARMALL JX 70 DT

Warning: This test requires trained personnel with PPE!

Binding test with hot oil and valve successful?

If binding test is not successful, report the issues to the maintenance team and stop the procedure

Enter the leakage rate for each section

Ensure the system is hot before proceeding

Are working ports A and B of each section connected to the cylinders?

Is the spool in the working position with oil flowing from A or B?

Has the spool reached the end of its stroke and the main relief valve opened?

Is the oil column pressurised from the working section to the cylinder?

WARNING: Handle all parts with care. Do not insert hands or fingers between one part and another. Wear suitable safety clothing, i.e. safety goggles, gloves and footwear.

Install the bevel pinion bearing cones (7) and (9) with spacer (8) on tool 293438 (E).

Measure the distance (H1) between the end of the pin on the bottom of the tool and the top surface of the tool.

Remove the bearing cones and spacer from the tool. Lubricate bearings with engine oil and re--install onto the tool, inserting differential carrier (10) with bearing cups.

Fully tighten tool nut (M) while rotating the differential carier through ten revolutions to settle the bearings.

Measure dimension (H3) of the tool in this condition.

Calculate thickness of shims (S1) as: S1= H3 -- H1 + 0.10 mm (0.00039 in.) If necessary, round off (S1) to the nearest 0.05 mm (0.0020 in.)

Leave the adjustment tool in place for adjustment of the drive pinion position.

WARNING: Handle all parts with great care. Never place your hands between one part and another. Wear suitable safety clothing, i.e. safety goggles, gloves and shoes.

To gain access to the synchroniser reverser--creeper unit, first remove the cab or platform following the instructions given in Sect. 27 and remove the clutch casing as described in Sect. 18, and then proceed as follows :

Fix the casing to the rotating stand 380000301 using the brackets 380000271 and 380000272.

Remove circlip (1) and slide out constant mesh gear (2).

Remove circlip (1) of reverser transmission driving shaft.

Remove plug and remove the control lever re- taining pin (1).

Remove the reverser synchroniser assembly (1) together with control forks and gears.

Withdraw the driven shaft gear (1) together with the roller bearings and remove the thrust washer.

Remove the control fork retaining springs (2) and withdraw the clutch pressure plate bearing assembly (1).

Warning: This procedure requires a battery/starting tester with incorporated 0--20V voltmeter and 0--500 A ammeter.

No wires in the starting system are broken or frayed

No loose connections in the starting system

Connect the positive voltmeter point (1) to the starter motor casing (2)

Connect the negative voltmeter point to the engine block (3)

Run the engine and check the readings on the voltmeter

Enter the voltage reading from the voltmeter

Warning: Disconnect the battery before starting the procedure

Disconnect B+ (2) and D+ (3) alternator terminals

Reconnect the battery and turn the ignition key into position ON but without starting the engine

Connect a voltmeter (4) between each terminal and earth (ground) (1)

Is there voltage at the battery?

If there is no voltage at the battery, check for a continuity fault in the external wiring. See circuit diagram in figure 2

Connect D+ terminal, warning light wire (red) and earth (ground)

Did the warning light illuminate?

Disconnect the battery and reconnect the cables to the alternator at (2) and (3) fig. 5
