Komatsu AFP49-1(530M S/N A30001-A30017 (AFP49-A THRU K) (DH627-1))

The AFP49-1 (Komatsu internal code DH627-1) is the earliest production block of the Dresser/Komatsu Haulpak 530M, a rigid-frame, mechanical-drive mining and quarry haul truck built in the early 1990s under the Komatsu Dresser joint venture. Power comes from a Cummins KTA50-C V16 diesel with a mechanical PT fuel system and no engine control module, driving through a torque converter and TORQFLOW powershift transmission into a plug-in differential and planetary final drives at each rear wheel. Gross vehicle weight runs roughly 240-250 tonnes (530,000-550,000 lb) with a nominal rated payload class of about 129-144 tonnes (142-159 US tons), figures that vary by configuration across the wider 530M/HD1500-5 family. This S/N A30001-A30017 block (build letters AFP49-A through K) precedes the later A30018-A30035 (AFP49-3/DH627-3) 530M run and the separate Soloman-configuration AFP49-W trucks. Standard equipment included full-time power steering, oil-disc service and parking brakes with a retarder for grade control, and an optional Payload Meter II onboard weighing system.

Later 530M serial blocks refined the same mechanical-drive platform before Komatsu carried the lineage forward as the HD1500-5, which trade coverage of its own successor ties directly to the 530M as sharing running gear, and which was later followed by the HD1500-7 with a nominal payload increase to roughly 159 tons. The AFP49-AM and AFP49-X model codes cover that later HD1500-5-generation badge on the same family tree; this AFP49-1 block predates that transition and keeps the original Dresser-era Cummins KTA50-C engine and TORQFLOW driveline rather than any later Komatsu-sourced engine. In the used and parts market, that mechanical simplicity is the appeal: no ECM to fault-code, an engine family shared with generator, marine, and other industrial KTA50 applications that keeps engine parts reasonably available, and a rebuildable torque-converter/powershift driveline that mines favor for straightforward field diagnosis. Buyers should expect parts to be cataloged under Dresser, Komatsu Dresser, or Komatsu numbers depending on the source, and should confirm the exact serial block before assuming a spec sheet or parts list applies, since the 530M designation was reused across more than one distinct build range.
