Programmable Top Gear. Transmission top gear maximum can be set using the Cat ET service tool to help the operator maintain speed limits. Anti-Hunt Function. Minimizes shifting by not allowing the transmission to up or down shift immediately after a shift has occurred. This prevents gear hunting when operating near a shift point and minimizes transmission shifting for increased component life. Downshift Inhibitor. Prevents engine overspeeding by keeping the transmission from downshifting until engine speed reaches the downshift point. Electronic Technician (Cat ET). Cat ET service tool...

Caterpillar Brake System Reliable braking with superior control gives the operator the confidence to focus on productivity. Long Life. An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Pistons. The Caterpillar two-piece piston design combines the service, secondary, parking brake and retarding functions in the same system. The primary piston hydraulically actuates both service and retarding functions. The secondary piston is spring-applied and held in the disengaged...
