Mount Brake on The bracket
46㎜ Tightening tool: Wrench 46 mm
1.1 0.2㎜ Check the parallelism of the bracket: 0.2 mm
1.2 Place the two halves on the sides of the bracket (with the side of the exhaust valve facing up) and tighten the screws:
8 pcs of M30 × (366 + B) double head screws Grade 12.9, tightening torque = 1350 NM
(B-brake disc thickness)
2. Hydraulic connection, oiling and exhaust
2.1 connected with the hydraulic station
Every half of the brake mounting-M18 × 1.5 tube joints (amount ∮ 28 × 1.5 copper gasket on the connection of tube joints and brake oil inlet), connect the hydraulic station through the oil pipe, clean whole pipes, fittings and ensure connected to the hydraulic station, and ensure that the entire hydraulic system is completely cleaned (no dust, no fines).
2.2 Recommended oil: anti-aging mineral oil, 40 ℃ viscosity of 20-100 mm2 / S
2.3 Steps: For every half of the brake
2.3.1 Unscrew the bonnet on the exhaust valve, screw the supplied test exhaust pipe onto the exhaust valve, and divert the other end into the container containing the oil.
2.3.2 Fill the cylinder of the brake with a hydraulic station (maximum pressure: 20 bar) or manual pump. Be careful not to drain or spill on the brake disc.
2.3.3 When no bubbles emerge from the exhaust pipe, unscrew the exhaust pipe, pay attention to the oil retained in the tube. Re-screw the bonnet.
3. Installation and adjustment
3.1 Apply 150 bar of hydraulic pressure and maintain this pressure throughout the process.
3.2 Loosen the lock nut (2).
3.3 Release the wear adjustment screw (1)
3.4 Install the brakes in place.
3.5 Check the disc beating, maximum ± 0.2 mm
3.6 Check the bracket relative to the brake disc symmetry: 0.5 mm.
3.7 Tighten the wear adjustment screw (1) until the clearance is 1+0.1mm
between the friction plate and brake disc.
3.8 Tighten the lock nut (2) and lock the wear adjustment screw (1).
3.9 Test the brake through the oil, pressure relief several times, observe the brake release, clamping action state, re-check the gap between each friction plate and the disc. The gap can not exceed 1.5 mm. This number means that each friction plate has 0.5 mm wear, braking torque decreased by 8%
4. Adjustment and replacement of friction plate
4.1 When the gap between the friction plate and the brake disc is greater than 1.5 mm, the friction plate gap adjustment according to 3.1,3.2,3.7,3.8,3.9 steps.
4.2 When the thickness of friction plate reach 4 mm, it should be replaced.
Tightening tools: wrench 30 mm, tightening torque: 200 NM.
4.2.1 Follow steps 3.1, 3.2.
4.2.2 Release the wear adjustment bolt (1) until there is a clearance of 10 mm between the friction plate and the disc.
4.2.3 Remove the bezel (4), 4 pcs of M20 bolts (3) and 4 flat washers from the side where the exhaust valve is installed.
4.2.4 Remove the bezel (4), 4 pcs of M20 bolts (3) and 4 flat washers from the side where the exhaust valve is installed.
4.2.5 Re-install the new friction plate, press the bezel (4), four fastening bolts (3), and four washers
4.2.6 Adjust the clearance of the friction plate by steps 3.7, 3.8, 3.9.
5. The braking force is set and tested during manufacture.
The maximum braking force is: single gap 1.5 mm 150000N
Please don’t change the braking force casually for your safety.
