Komatsu GD525A-1, GD525A-1A, GD525A-1B & GD525A-1C Repair Manual

This Komatsu GD525A repair manual covers the GD525A-1, GD525A-1A, GD525A-1B and GD525A-1C variants within publication SEBMG5250107. The 650-page English shop reference dates from February 1993. Its application table distinguishes the base -1 and -1A machines from the later -1B and -1C serial groups.

Included documents and coverage

• GD525A-1 and GD525A-1A from serial 50001; GD525A-1B from 55001; GD525A-1C from 60001.
• Power train, steering, braking, hydraulics and work equipment sections.
• Component checks, assembly procedures and inspection standards, with electrical/electronic reference information.

Choosing the correct reference

Check the complete variant suffix before applying a serial threshold. For example, the 50001 starting point for GD525A-1A does not replace the 60001 starting point for GD525A-1C. The shared family manual uses model and component applicability information to distinguish procedures. Use those entries when selecting the relevant repair section. A separate engine overhaul manual, operator handbook or parts catalog is not specified as included.
