10 Brakes Steering System and Brakes Adjustment Linkage (On Tractors with SG2 Cab) 1. Adjust front adjusting rod 50 (fig. 12) so that spring 14 applies a certain return force on handbrake lever. 2. Adjust rear adjusting rod 40 so that it can be connected to lever 18 and link 43 without tension. 3. On Earlier Tractor Series: Move handbrake lever 59 forward to stop. Attach sending unit 9 to toothed quadrant 57 so that contact pin of sending unit is against handbrake lever and handbrake indicator light is not on. On Later Tractor Series: Move handbrake lever forward to stop. Attach sending unit 63 (solenoid switch) of handbrake indicator light to toothed quadrant 11 so that with a clearance of at least 5 mm (0.2 in.) between magnet 61 and sending unit 63 the indicator light goes out. With a clearance of 10 mm (0.4 in.) the indicator light should glow. Fig Adjusting Brake Band Adjusting Screw Brake Band (On All Tractors) 1. Apply handbrake lever so that its latch engages in first notch of toothed quadrant. 4. Loosen brake band adjusting screw until handbrake lever latch engages in third or fourth segment of toothed quadrant, when handbrake lever is applied with a force of 110 N (25 lb) as shown below (fig. 14). 2. Tighten brake band adjusting screw 21 (fig. 11 and 12) finger-tight (see fig. 13). 3. Tighten brake band support screw 28 (figs. 11 and 12) at bottom of transmission case fingertight. Then back off a half-turn and secure by means of hex. nut 27. Fig Adjusting Handbrake TM-4373 (Apri/-86) Printed in Germany (B 2) Tractor

11 Hydraulic System Description, Diagnosing Malfunctions Tests HEATING THE HYDRAULIC OIL F 14 - Covering the Hydraulic Oil Cooler Cover hydraulic oil cooler with a piece of cardboard (fig. 14). This will help to heat the draulic oil more quickly. IMPORTANT! Do not cover the radiator as this would cause overheating of engine. 2. Run engine at 2000 rpm. 3. Move selective control valve lever to circulate oil to second quick coupler or oil flows to sump through oil filler neck. NOTE: You can heat the hydraulic oil more quickly by installing a restriction orifice in hydraulic jumper hose. 4. Adjust selective control valve so that a lube oil pressure of 50 kpa (0.5 bar; 7 psi) is maintained (see figs. 15, 16 or 17). NOTE: It is easier to adjust the lube pressure when an adjustable flow control valve is installed. 5. Observe the thermometer and shift selective control valve lever to neutral position when hydraulic oil has reached the desired temperature of 650C ( 1500F).

12 Air Conditioning System Operator's Cabs NOTE:Before installing the remammg parts, the compressor should be tested for leakage of refrigerant (see "Shaft Seal Leak Test", page 38). 22. Install a new felt seal by rolling the material into a cylinder, overlapping the ends, and placing seal in the interior of compressor neck. 23. Carefully position seal so that the ends butt together. Fig A Shaft seal assembly Installing Shaft Seal Assembly B Special tool AC-415* C Seal protector 15. Make sure seal is properly positioned by having the flats of the seal assembly aligned with flats on compressor shaft. 16. Release AC-415* tool from seal assembly by twisting tool slightly counterclockwise. 17. Coat face and outside edge of new seal seat with clean compressor oil, and install seal seat using D-05284ST tool. NOTE: Make sure that seal seat 0-ring is not dislodged, and that seal seat is making good contact with the 0-ring. 18. Install seal seat retainer ring with flat side against the seal seat. 19. Place retainer ring in bore of compressor neck with snap ring pliers. 20. Complete installation by using AC-460* tool to help force the retainer ring into the groove. Do not use a hammer! 21. Remove excess oil from inside the compressor neck with a clean cloth. Fig A Bearing rear shield Installing Bearing Rear Shield B Driver C I nstallatlon tool 24. With felt seal properly positioned, insert a new pulley bearing rear shield (A, fig. 34) into bore of compressor neck. 25. Using JOST-26-4B installation tool (C, fig. 34) and driver (B), drive shield in until it bottoms on outer end of neck. NOTE: The outer face of the rear shield which contacts the front shield has a Teflon coating. Therefore, no lubricant of any kind should be used on this surface. * Part of tool D ST TM4313 (Apri/-86) Printed in Germany (A 4) Tractor- 2140
