11 DISC BRAKE REMOVAL INSTALLATION Removal Procedure Raise the inner mast and securely fix it to prevent lowering. [Point I] Remove the brake cover. Remove the toe board (front and rear) and tilt cylinder cover. Remove the instrument panel. Disconnect the links from the brake pedal and parking brake. Disconnect the brake rods between frame and brake ASSY (LH and RH). Remove the brake ASSY (LH). Remove the brake ASSY (RH). Installation Procedure The installation procedure is the reverse of the removal procedure.

12 Point Operations [POINT I] Removal: Raise the inner mast and support it by putting wooden block inside the outer mast rail to prevent the inner mast lowering.

13 9-1 0 DISASSEMBLY INSPECTION REASSEMBLY T=N-m (kgfcm) [ftdbfl Disassembly Procedure 1 Remove the pin, castle nut and lever. 2 Separate the lever ASSY No.1 and 2. [Point I] Reassembly Procedure The reassembly procedure is the reverse of the disassembly procedure.

14 Point Operations [POINT I ] Inspection: Measure the pad thickness. Standard: 6.0 mm (0.24 in) Limit: 3.5 mm (0.14 in) DISK BRAKE ADJUSTMENT 1. Adjust the pad clearance with adjusting bolt. Pad clearance: 9.8 to 10.2 mm (0.39 to 0.40 in) 2. Adjust the clearance between the brake disc wheel and pad evenly with an adjusting bolt. Clearance: 0.4 to 0.6 mm (0.016 to in) A=0.4 to 0.6 mm (0.016 to in) B=9.8 to 10.2 mm (0.39 to 0.40 in) C=9 mm (0.35 in)

15 -- - BRAKE DISC WHEEL REMOVAL INSTALLATION Removal Procedure 1 Remove the disc brake ASSY. (See page 9-8.) 2 Remove the brake disc wheels (LH and RH). [Point I] Installation Procedure The installation procedure is the reverse of the removal procedure.

16 Point Operations [POINT I] Removal: Raise the inner mast and support it by putting wooden block inside the outer mast rail to prevent the inner mast lowering. [POINT 21 Inspection: Inspect the brake disc wheel thickness. Standard: 9.0 mm (0.35 in) Limit: 8.0 mm(0.31 in)

17 9-1 4 BRAKE PEDAL REMOVAL e INSTALLATION T=N.m (kgfcm) [ftdbfl Removal Procedure 1 Remove the toe board (front and rear) and tilt cylinder cover. 2 Remove the instrument panel. 3 Remove the brake pedal set bolt. 4 Disconnect the link and remove the brake pedal. 5 Disconnect the parking brake wire. 6 Remove the brake pedal adjusting nut. 7 Remove the brake pedal link. 8 Remove the parking brake adjusting nut. 9 Remove the parking brake link. 10 Remove the brake ASSY link. 11 Remove the brake link ASSY. 12 Remove the brake link ASSY pin. Installation Procedure The installation procedure is the reverse of the removal procedure. Note: Inspect the bushing for wear and damage and replace it if necessary.

18 BRAKE PEDAL ADJUSTMENT 1. Inspect brake pedal height A (from pedal to the upper side of the pedal). Standard: A = 11 0 to 11 5 mm [4.3 to 4.5 in] Adjust if the pedal height is outside the specified range with a stopper bolt. 2. Tighten the adjusting nut until the equalizer is securely fixed. Adjust the pedal stroke B when the clearance between the brake pad and disc is within the standard (0.4 to 0.6 mm[0.016 to in]). (Reference value): B = 30 to 35 mm [I.I8 to 1.38 in] 3. After the adjustment, inspect the ground clearance C (from the toe board to the top of the pedal) with fully depressing the brake pedal. If the ground clearance C is standard or below, adjust the clearance between the brake pad and disc. Standard: C = 55mm [2.17 in]

19 9-1 6 PARKING BRAKE REMOVAL INSTALLATION T=N.m (kgf.cm) [ft.lbfl Removal Procedure 1 Remove the instrument panel. 2 Disconnect the parking brake wire. 3 Remove the parking brake ASSY. Installation Procedure The installation procedure is the reverse of the removal procedure.

20 PARKING BRAKE ADJUSTMENT 1. Adjust the parking brake so that the front pole fits at the third or fourth notch of the sector when the parking brake lever operating force is at 150 N (15.3 kg) [33.7 Ib] (measure at the point in the illustration). 2. When the disc brake drags, adjust it so that the front pole fits at the fifth notch.

22 SERVICE INFORMATION BULLETIN Drive Motor DM May 31, FBEU AC Motor Bearing Change (RPM Sense) 7FBEU15-20, 7FBEHU18 Subject: 7FBEU AC Motor Bearing Change (RPM Sense) Page 1 of 2 MODEL APPLICATION: 7FBEU15-20, 7FBEHU18 GENERAL INFORMATION: The bearing supplier has been changed and new bearings were released into production in August Please note that the parts from the old design and new design are not interchangeable. REPAIR INFORMATION: Please add the following pages to your repair manual CU330. *Pages 5-3A and 5-4A need to be inserted in your manual. *Pages 5-7, 9-2 and 9-6 replace the original pages in the manual. *Page 2 of this bulletin indicates the pump motor and the bearing (RPM Sense) were also changed but no torque specifications have been changed (just the motor end frame to accommodate the larger bearing).

23 Subject: 7FBEU AC Motor Bearing Change (RPM Sense) Page 2 of 2 Pump motor bearing 01A also was changed 8/2012. Motor end frame was changed (41) and bearing retainer (AV) was not changed.
