Tractors, pumps, and working machinery

Reproduce the geometry
when the part number is not enough.

Older machines are modified, rebuilt, and repowered. Identify the exact component and measure the gasket in front of you rather than assuming a model name guarantees fit.

Useful project types

Access and inspection covers

Flat covers on gear cases, hydraulic reservoirs, pumps, and industrial machinery.

Pump and coolant joints

Two-dimensional housing and flange gaskets with fully documented openings.

Vintage tractors and engines

Obsolete flat gaskets supported by an original, service drawing, or measurable mating face.

Shop-built machinery

Custom covers, enclosures, and low-volume equipment with known engineering requirements.

Record machine identity carefully

  • Manufacturer, model, serial-number range, and approximate year.
  • Engine, pump, transmission, or attachment identification separately.
  • Component name and exact mounting location.
  • Any evidence the machine was repowered or modified.
  • Part numbers stamped on the component or listed in the manual.

Measure the joint, not only the old gasket

A used gasket can shrink, stretch, tear, or remain compressed. When access is safe and the equipment is fully isolated, compare the old gasket to the clean mating surface. Record hole diameters, center distances, passages, outside envelope, and any location where the gasket must not obstruct flow.

Service conditions to document

List the actual fluid or gas, temperature range, pressure or vacuum, outdoor exposure, vibration, flange material, surface condition, bolt pattern, and applicable code or certification. Material family descriptions are not engineering approval.

Safety boundary: Shut down, depressurize, drain, cool, lock out, and otherwise isolate equipment according to its procedures before measuring a mating surface. Do not use a custom part where the equipment manufacturer, law, insurer, or applicable code requires a certified component.

Send the strongest source available

  1. Original service drawing or dimensioned CAD file.
  2. Clean flatbed scan of the complete old gasket.
  3. Square overhead photo with verified scale.
  4. Tracing plus multiple direct measurements.

Use more than one source when possible. The production proof is the final geometry check before cutting.
