FAQ

Q1: Is this cylinder liner a direct replacement for the original Mitsubishi part 32A47-00310?
Yes, this liner is manufactured as a direct aftermarket replacement for the OEM Mitsubishi part number 32A47-00310. It matches the original dimensions, material grade, and surface finish for a drop-in fit on the S4Q2 engine block. We recommend checking your old liner for any visual differences, but in most cases, no modifications are required.

Q2: What is the recommended installation procedure for this liner?
Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly clean the cylinder block bore. 2) Apply a thin layer of anti-seize compound or engine oil to the liner’s outer surface. 3) Use a suitable press or hydraulic tool to insert the liner evenly. 4) Check for correct protrusion above the block deck using a dial gauge. 5) Verify the liner bore is round and within specification after installation. Never force the liner; if it binds, re-check the block bore for damage.

Q3: How does this aftermarket liner compare in quality to a genuine Mitsubishi part?
This aftermarket liner is manufactured to meet or exceed the OEM performance standards. It uses a premium grade of cast iron and undergoes rigorous quality control, including hardness and dimensional checks. While it is not a “genuine” Mitsubishi part, it offers a reliable, cost-effective alternative that is widely used in the heavy equipment repair industry. We have tested it extensively in S4Q2 engines with excellent results regarding wear resistance and service life.
