Komatsu D57S-1B(S/N 20001-UP (S6D108-1 Eng. Installed))
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu D57S-1B is a medium-class crawler bulldozer produced from 1979 to 1986. It is powered by the S6D108-1 engine and features a transport length of 5.47 meters (17 ft 11 in), a transport width of 2.15 meters (7 ft 1 in), and a transport height of 2.93 meters (9 ft 7 in). The machine has a standard operating length of 5.61 meters (18 ft 5 in) and a travel speed of 9.5 km/h (5.9 mph). It succeeded the D57S series and was followed by the D575A series in Komatsu's larger dozer lineup. Configurations included standard dozer and ripper setups.
The D57S-1B represents a transitional generation in Komatsu's medium dozer history, bridging the gap between earlier D57 models and the heavier D575A series. It matters in the used and parts market today because its S6D108-1 engine and robust undercarriage are widely compatible with other D57S, D58E, and D58P models, creating a large pool of interchangeable components. Its age makes it a target for rebuilds, driving demand for specific engine and transmission parts.

Servicing the D57S-1B(S/N 20001-UP (S6D108-1 Eng. Installed)) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA oil analysis at every 500-hour interval to monitor engine wear metals and hydraulic contamination. Check coolant SCA levels at 500 hours to prevent scaling in the S6D108-1 cooling system. Monitor hydraulic oil particle counts to detect pump wear early. Track fuel dilution in engine oil samples to identify injector issues. Use KOMTRAX telematics to correlate load frequency with fluid degradation rates for optimized change intervals.
Corrective & Common Repairs
Address frequent S6D108-1 turbocharger inspections at 1,000 hours to prevent boost loss. Replace hydraulic return filters at 500 hours to protect valve spools from debris. Inspect final drive oil for metal particles at 1,000 hours to catch gear wear before failure. Check ROPS bolt torque at 1,000 hours for cab safety compliance. Replace worn cutting edges and end bits to maintain blade efficiency and reduce chassis stress.
Overhaul & Rebuild Points
Plan major engine overhaul around 10,000-12,000 hours based on compression and oil consumption trends. Rebuild hydraulic pumps and motors when KOWA analysis shows excessive copper or iron wear. Inspect undercarriage wear at 1,000-hour intervals; replace sprockets, idlers, and track chains when pitch elongation exceeds limits. Evaluate transmission clutch packs during the 2,000-hour service for slippage signs. Consider structural weld repairs on the frame and push arms during major overhauls.
Seasonal & Environment Servicing
In cold climates, check coolant freeze protection before winter. Drain water from the fuel separator daily to prevent ice formation. Use lower viscosity engine oil if operating below -18°C (0°F). In dusty environments, clean the air filter outer element more frequently and check the restriction indicator often. In wet conditions, inspect track tension daily to prevent slippage and check undercarriage for mud buildup that accelerates roller wear.
