To adjust the master cylinder linkage:

1 Check that the pedal is adjusted properly before adjusting the master cylinder linkage. Refer to Brake Pedal Assembly Repair section for procedures.

2 Loosen the lock nut on the push rod.

NOTE: Do not allow the boot to be twisted while adjusting the push rod length.

3 Turn the push rod to counterclockwise (as viewed from rear of truck) to remove all slack between the master cylinder and the brake pedal.

4 Turn the push rod 1/8 clockwise (as viewed from rear of truck) to allow the master cylinder to fully return when the brake pedal is released.

5 Hold the push rod in position, and tighten the locknut on the push rod against the clevis to secure in place

WARNING

Always wear the proper protective equipment including eye protection and petroleum-resistant

gloves when handling oil. Thoroughly wash oil from exposed areas of skin as soon as possible.

Never check for leaks by putting hands on pressurized lines or components under pressure. Pressurized oil can be injected into the skin.

Pressure is transferred from the master cylinder to the transaxles through brake lines. These are metal tubes filled with oil connected by hydraulic fittings. Brake lines run below the floor plates, from the master cylinder to a tee fitting located near the front of the frame. They continue from there as separate left-hand (LH) and righthand (RH) lines through the frame to a fitting on each

transaxle. The drive wheel may be removed to access this connection.

How to Measure and Test Fuel Return System for Fendt 900 Vario

If the pressure in the return line is too high, the pressure in the dispensing unit also rises. This causes too much fuel to be delivered to the high pressure pumps, which means that the pressure in the rail is above the value set by the engine control unit (A051).

Therefore, if this error occurs, the return pressure must be measured and the target and actual rail pressures must be compared using SERDIA at the same time.

Remove the banjo bolt from the return pipe, screw in banjo bolt with measuring connection 199.110.620.010 and connect a pressure gauge (-1 bar to +1.5 bar)

Target pressure: 0.2-0.5 bar

Connect SERDIA adapter (level 3) to X810 diagnostics socket and launch the program

In the list, find the two values for rail pressure target value and max. rail pressure (see arrows), and compare these two values.If the return pressure is greater than 0.5 bar and the max. rail pressure is greater than the rail pressure target value, the fuel return system must be checked.

First check whether the return lines are kinked. If nothing is observed there, the components must be removed from the return system one after the other. First disconnect the return line from the engine control unit (A051) and connect it directly to the tank, then repeat the measurement. If the pressure is correct now, the problem lies in the cooler duct of the engine control unit. If the pressure is still incorrect, proceed as described above with the next component.

How to Perform Case IH 20 Series Axial-Flow Combine Low Pressure Standby

This instruction show guide on how to perform CASE IH 20 series Axial-Flow combine low pressure standby.This test is used to determine low-pressure standby.There are two items responsible for low pressure standby,the 375-400 PSI (26-28 bar)spring on the flow compensator spool and the 0.078 mm (0 .031 in)orifice in the steering hand pump –which creates back pressure in the signal line of approximately 50-150 psi.The 375-400 PSI (26-28 bar)spring plus the back pressure will equal low-pressure standby.The following test will show the spring setting of the flow compensator spool.

TEST PROCEDURE

1 Attach a 69 bar (1000 psi)gauge to the signal line pressure test port (14)on the main valve assembly.It is recommended to install a needle valve in the test hose to prevent damage to the gauge.With the needle valve closed,start the engine.At low idle,open the needle valve on the gauge.Make sure that the steering wheel is not moved or that other hydraulic functions are not activated otherwise the gauge could be damaged. The signal line pressure should be approximately 50-150 PSI (3 .45-10.4 bar).Record this number for use later.

2 Then attach the SAME 69 bar (1000 psi)gauge to the PFC pump pressure test port (13) on the main valve assembly.With the needle valve closed,start the engine.At low idle open the needle valve on the gauge.Make sure that the steering wheel is not moved or that other hydraulic functions are not activated otherwise the gauge could be damaged.The PFC pump pressure port should read 375-400 PSI (26-28 bar)above the reading that was recorded from the signal line.

If the PFC pump pressure port does not read 375-400 PSI (26-28 bar)ABOVE the signal line, adjustment of the flow compensator spool spring is required.The adjustment procedure is as follows:

Example Signal line pressure port reading 112 psi (7 .7 bar) Flow compensator spool spring setting +400±25 psi (27 .5 bar

PFC pump pressure port reading AFTER adjustment 512±25 psi (35 .3 bar)

3 Remove the cap for the adjustment screw located on the compensator.

4 Loosen the jam nut.

5 Use an allen wrench to adjust the pressure to match the number calculated.(See example.)

6 Tighten the jam nut.Repeat test to verify the low-pressure standby setting.

7 If not correct,make adjustment again.If it is correct,replace the cap.
