ABOUT THIS SECTION: The M48 is part of the Cub Cadet Commercial Tank Series. The 2004 model year M48 is very similar to The 2001 model year Tank. Earlier versions of this machine have been covered in the “2001 Cub Cadet Commercial Technical Handbook”: Form #77010528. 2. CHANGES FOR ‘03 AND ‘04 • New hydro motor frame assembly • New hydro motors • New brakes and brake linkages • Finer increments of height adjustment • Different choice of engines • Features of the 72” TANK The content of this section is intended to detail changes in service techniques that have occurred since the introduction of the M Series. 3. DRIVE SYSTEM ADJUSTMENT 3.1. Prior to making any adjustments to the drive system, inspect the hydro control linkages, drive belt, brake linkage, tires, fluid, and filter. 3.2. The hydraulic reservoir and filter are accessible beneath the seat. See Figure 3.2. Figure 3.2 RESERVOIR OIL FILTER BATTERY 3.3. The hydraulic fluid level should be at the second hole in the filler neck of the reservoir. See Figure 3.3. Figure 3.3 FLUID LEVEL FIRST HOLE SECOND HOLE NOTE: It is very important that the hydraulic oil does not become contaminated. Clean the surrounding area thoroughly prior to opening any part of the hydraulic system. NOTE: The hydraulic drive system contains roughly 3.25 gal. of SAE 20W50 motor oil having an API rating of SJ-CD or better. Hydraulic Drive System Fluid Plus (P/N: 737-3121 gal.) is an acceptable premium alternative. NOTE: Complete draining and filling instructions are contained in the “Operator’s and Service Manual”. 3.4. Tracking is effected by the circumference of the rear tires, and the amount of drag produced by the front tires. • Rear tire pressure may be adjusted within the range of 8-10 PSI to achieve equal rear tire circumference. • Front tire pressure should be within the range of 20-25 PSI. 1 M48 Tank 3.5. For complete brake adjustment procedures, refer to the “Brake Adjustment” section of this manual. For the purpose of tracking, insure that the brake linkage bellcranks and rods are well lubricated, not damaged, and work as intended. See Figure 3.5. Figure 3.5 BRAKE CONNECTING Link Brake REAR BRAKE ARM ASSEMBLY BELLCRANK MOUNTING ROD SHAFT 3.6. To check for brake drag, open the the relief valve 3.7. If in doubt about the source of brake drag, disconnect the brake link rod from the actuator arm on the brake assembly. The actuator arm should return to center, releasing the brakes. See Figure 3.7. BRAKE LINK BRAKE ACTUATOR ARM Figure 3.7 3.8.Check the condition of the belt tensioner and belt that drives the hydro pumps. See Figure 3.8. Figure 3.6 HYDRO PUMP HYDRO RELIEF VALVE OPEN on each hydro pump. With the parking brake released, both wheels should rotate with hand pressure. See Figure 3.6. 3.9. Before making neutral control and tracking adjustments, make sure the relief valves on both hydro pumps are fully closed. NOTE: Some hydraulic system drag will be 3.10. To check neutral control, safely lift and support present, but a dragging brake will be immedi the rear wheels of the Tank. ately apparent. 3.11. Start the engine, and release the parking brake. Do not move the lap bars from the neutral position. If either wheel rotates, neutral control adjustment will be necessary. Turn off the engine. DRIVE BELT TENSIONER Figure 3.8 2 M48 Tank 3.12.
