INTRODUCTION
Basic instructions - Shop and assembly
Shimming
For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a microm-
eter, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or
the rated value shown on each shim.
Rotating shaft seals
For correct rotating shaft seal installation, proceed as follows:
1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.
2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.
3. Position the sealing lip facing the fluid.
NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that
they will move the fluid towards the inner side of the seal.
4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip
and the dust lip on double lip seals with grease.
5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a
hammer or mallet.
6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that
the seal makes contact with the thrust element, if required.
7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.
O-ring seals
Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and
twisting, which would jeopardize sealing efficiency.
Sealing compounds
Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing
compound, prepare the surfaces as directed by the product container.
Spare parts
Only use CNH Original Parts or CASE CONSTRUCTION Original Parts.
Only genuine spare parts guarantee the same quality, duration, and safety as original parts, as they are the same
parts that are assembled during standard production. Only CNH Original Parts or CASE CONSTRUCTION Original
Parts can offer this guarantee.
When ordering spare parts, always provide the following information:
• Machine model (commercial name) and Product Identification Number (PIN)
• Part number of the ordered part, which can be found in the parts catalog

10. Travel (right)
As an example, this section explains the forward travel operation.
The travel motor 2-stage tilting angle is a large angle side. Even if the travel switch is set to the high-speed side,
switching the key switch OFF and then ON again always returns the system to this state.
By operating the travel remote control valve to the forward side, the pilot pressure oil is fed to the control valve 5a1
port and switches the left travel spool to the forward side. At the same time, the oil is also fed to the 4a1 port to switch
the right travel spool to the forward side.
The discharge oil from hydraulic pump A1 enters the control valve PR (P1) port and the discharge oil from hydraulic
pump A2 enters the control valve PL (P2) port. Each flows to the respective travel motor and causes forward travel
through the left and right travel spools being switched.
The return oil from the travel motor goes through the left and right travel spools and returns to the hydraulic oil tank.

As an example, this section explains the brake circuit operation after the end of a right swing operation.
When the remote control valve is returned to neutral from a right swing operation, the pilot pressure oil is cut off and
the control valve swing spool returns to neutral. The pressurized oil fed to the swing motor B port from the control
valve 5B2 port is cut. At the same time, the destination location is eliminated for the pressurized oil flowing from the
swing motor A port to the control valve 5A2 port, so the pressure rises to the swing motor relief valve set pressure.
The pressure generated here becomes a brake force and stops the motor.
When the swing is stopped, the swing motor continues to rotate for a while due to inertial force. In order to make up
the shortfall in the oil volume, oil is supplied from the make-up line connected to the swing motor Mu port from the
control valve R2 port to open the make-up check valve and oil is suctioned in to prevent cavitation.

9. Second option pilot pressure switch
As an example, this section explains the case in which the hydraulic rotation fork attachment is used.
By operating the second option remote control valve to the right swing side, the pilot pressure oil is fed to the control
valve 4a5 port. The fourth hydraulic pump OUT discharge oil is fed to the control valve P3 port, goes through the
second option spool and flows to the hydraulic rotation fork to operate to the right swing side. The return oil from the
hydraulic rotation fork goes through the second option spool and returns to the hydraulic tank.
The oil in the second option drain line returns to the hydraulic tank without going through the control valve. second
option spool port relief valve pressure becomes the hydraulic rotation fork set pressure.
