D 75438 SPACER (HSA)

The D 75438 Spacer (HSA) is a precision-machined engine mounting and pump coupling spacer designed for CASE 580 F and CASE 580 G backhoe loaders. This spacer plays a vital role in maintaining correct alignment and spacing between engine components, mounts, and pump coupling assemblies.

Manufactured by HSA, this spacer is produced using durable, high-quality material to withstand engine vibration, load stress, and continuous operation commonly found in heavy-duty construction equipment. Proper installation of this spacer helps prevent misalignment, uneven wear, and premature failure of engine mounts and hydraulic pump coupling components.

This spacer is designed to OEM-correct dimensions, allowing for direct replacement during engine repair, mounting service, or hydraulic pump alignment work.
