Buying questions
Is SA6D170E-3 the same as SAA6D170E-3?
No interchange is established. Komatsu lists the single-A model for D375A-5 and double-A variants for other machinery and generators; compare the exact original and offered arrangements.
Can the manual's 2,740 kg dry weight be used as freight weight?
No. It is Komatsu's dry reference weight for a D375A-5 configuration, excluding packing and potentially different supplied accessories. Confirm the packed weight of the actual assembly.
