Product information:
For tractors that do not have a hydraulic trailer brake valve. (Because of the space) The connection is on top.
To improve the durability at low temperatures, the piston (5149453 replaced by new piston 87590454 and new cold-resistant sealing ring 87590455).
Attention brake pressure cans have different connection holes for connection to the brake manifold.
(in installed condition pressure box screw connection at the rear )
87612052 mounted on the right side in the direction of travel Connection to the brake manifold on the top outside
87612053 Direction of travel mounted on the left Connection to the brake distributor at the top on the outside
87612485 Direction of travel mounted on right Connection to brake distributor at bottom outside (version with trailer brake valve)
Bleeding the brake system
Depress the left brake pedal fully so that the brake oil comes under pressure.
Keep the pedal depressed and open the banjo bolt under the right-hand brake pressure reservoir slightly and allow the oil/air mixture to flow out.
Tighten the banjo bolt again and only then release the brake pedal.
Repeat this procedure until bubble-free oil comes out.
Repeat this operation on the right brake pedal (bleeding at the same banjo bolt).
Now bleed the brake distributor (under the brake oil tank).
Left brake pedal connection front, right brake pedal connection rear.
Lock brake pedals mechanically .
Bleed the brake caliper.
In some cases it may be necessary to disconnect the brake caliper from the brake caliper and hold the bleed screw at the highest position and bleed in this position.
(To eliminate any air bubble in the caliper ,which can not be removed when the caliper is installed).
Function:
In resting condition pedal above may have brake pressure can no tension on the linkage .(Adjustment over Oesenschraube).
The bottom compensating line connection must be tight when not in use. CNH has installed steel balls of different sizes to compensate for the tolerances.
The inlet valve to the reservoir must be open at rest and closed when the brake is applied.
Caution: Install this valve only when the brake piston has been actuated a few mm inside, otherwise this valve will be damaged.
Example: If during bleeding of the left brake pedal oil is pressed through the transparent line of the right brake pressure can into the tank.
Is the right input valve of the brake pressure box defective ,or not equipped with the correct ball from the factory.
Steel ball 12.0mm 12.70mm 13.00mm 13.49mm
