[. . . ] High-tensilestrength steel comprising the front and sides of the blade increases durability. Dual Tilt Dozer (option) The dual tilt dozer increases productivity while reducing operator effort. K-Bogie Undercarriage System New K-Bogie Undercarriage System combines prior advantages with new additional features. Current features: Effective length of track on ground is consistent. Shoe slippage is minimized, resulting in higher traction. The idler does not oscillate under load, providing excellent machine balance. Blade and ripper penetration force remains stable for increased productivity. Optimum blade cutting angle for all types of materials and grades can be selected on-the-go for increased load and production. The D375A-5 provides the operator with a quiet, comfortable environment where he can concentrate on the work at hand. EASY EASY MAINTENANCE MAINTENANCE Preventative Maintenance Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the D375A-5 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy. Centralized Service Station To ensure convenient maintenance, the transmission and torque converter oil filters are both arranged next to the power train oil level gauge. Enclosed Hydraulic Piping Hydraulic piping for the blade tilt cylinder is completely housed in the push arm protecting it from damage. Hexagonal Pressurized Cab The cab's new hexagonal design and large tinted glass windows provide excellent front, side, and rear visibility. Air filters and a higher internal air pressure combine to prevent dust from entering the cab. Photo may include optional equipment. Modular Power Train Design Monitor with Self-Diagnostic Function Starting switch turned ON, the monitor displays P on the upper part of the display, service meter on the lower part of the display and Check-before-starting and caution items appear on the right part of the liquid crystal panel. The monitor finds abnormalities, corresponding warning lamp blinks and warning buzzer sounds. The monitor displays engine rpm and forward/reverse gear speed on the upper part of the display during operation. When error occurs during operation, user code and service meter are displayed alternately. When a high importance user code is displayed, a caution lamp blinks and warning buzzer sounds to prevent the Mode for operator development When normally operated When error occurred of serious Forward/reverse, speed display Engine tachometer problems. Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage, making servicing work clean, smooth, and easy. Comfortable Ride with New Cab Damper Mounting and K-Bogie Undercarriage D375A-5's cab mount uses a newly designed cab damper mounting which further improves viscous damper and provides excellent shock and vibration absorption capacity with its long stroke. The cab damper mounting, combined with new K-bogie undercarriage, softens shocks and vibrations while traveling over ripped ground that are impossible to absorb with conventional cab mounting methods. The soft spring cab damper isolates the cab from machine body, suppressing vibrations and providing a quiet, comfortable operating environment. Oil Pressure Checking Ports Pressure checking ports for power train components are centralized to promote quick and simple diagnosis. Maintenance-Free Disc Brakes Wet disc brakes require less maintenance. Enlarged Engine Room Engine room space is enlarged by increasing engine hood height, facilitating maintenance of the engine and related equipment. Solid engine hood prevents dust and rain from entering and keeps the engine clean. New Suspension Seat D375A-5 uses a newly designed suspension seat. Fore and aft sliding rails and suspension spring are newly designed, increasing strength and rigidity and reducing play of joints. New seat provides excellent support and riding comfort. Fore and aft sliding amount is designed to fit all operators. h Gull-wing Engine Side Covers Photo may include optional equipment. h Service meter User code Displayed alternately Gull-wing engine side covers facilitate engine maintenance and replacement of each filter. Side covers are a thick one-piece structure with bolt-on latch to improve durability and repairability. Cab Damper Mounting Fresh Air Intake from Rear of Engine Hood The air conditioner air intake port is now located at the rear of the engine hood where there is minimal dust. As a result, the air inside the cab is always clean. Cleaning interval of the filter is greatly extended, and use of a new structure filter element facilitates cleaning and replacement. Silicon Oil Rubber Boot Rubber Low Maintenance Costs Track Link with Wedge Ring New D375A-5 track links feature reduced press-fit force and a wedge ring.
