SECTION 3 MACHINE TRANSPORT AND STORAGE Page 6 MOVING A DISABLED MACHINE Fig. 3.2. Diagnostic Center – Tow and Pressure Check Ports 1. Right Brake Quick Coupler 2. Left Brake Quick Coupler If the tractor can be towed and the engine and steering hydraulic system can be operated, proceed as follows: 1. Lock the transmission shift lever in "NEUTRAL". 2. Start the engine. 3. Release the brake and decelerator pedal. 4. Use a towing cable of sufficient strength. Keep the engine running in the middle range of the idle speed and gear selector locked in “NEUTRAL” during the tow. If the tractor can be towed but the engine and/or steering hydraulic system is inoperable proceed as follows: 1.
Lock the transmission shift lever in “NEUTRAL”. 2. Open the diagnostic center cover on the LH side of the machine and connect a lubricating fitting and pressure gauge to one of the quick couplers (port 1 or 2, Fig. 3.2). 3. Release the decelerator and brake pedal. 4. Pump sufficient grease into one of the ports (1 or 2 in Fig. 3.2.) to release the brakes. Connected pressure gauge should show the pressure of 830 - 1030 [kPa]. The amount of grease required depends on the amount of pressure dissipation in the system. 5. Use a towing cable of sufficient strength. During the tow, it may be necessary to pump more grease into the quick coupling to replace loss of pressure. 6.
Depressing the decelerator and brake pedal will relieve hydraulic pressure and apply the brakes. 7. After towing is completed, actuate the steering levers until all grease is purged from the system and the pressure drops to zero (as measured on the brake port) while the decelerator and brake pedal is depressed and the steering levers are in the braking position. 8. Close the diagnostic center cover after disconnecting the lubricating fitting. TD-15H DRESSTA
