Retrofit

Recover the function. Preserve the machine’s value.

From an urgent mechanical problem to a documented replacement assembly. JESAKO connects fault assessment, re-engineering and integration with the machine’s future lifecycle.

Engineering for existing equipment

A practical route through the problem.

We define the scope around the actual machine, its condition and the information available. The sequence can be adapted to the project; it is not a promise of a fixed recovery time.

01

Emergency Engineering

Start with an initial technical assessment. Describe what has failed, what the machine must do and which information is available. Mechanical fault diagnosis and a clearly scoped quotation establish the next step.

  • Machine function and fault description
  • Existing drawings, photos and component identification
  • Known operating restrictions and responsibility boundaries
02

Immediate measures

Practical measures may support safe recovery, depending on the actual machine and the agreed scope. The condition of the equipment and the operator’s responsibilities guide what can be done.

  • Define the limits of any interim measure
  • Review relevant mechanical and control interfaces
  • Agree checks before a return to operation
03

Re-engineering

Measure the original, reconstruct the function and improve the replacement design. Calculations, CAD and drawings create a controlled basis for the next assembly.

  • Space, loads, movement and interfaces
  • Wear mechanisms and known weak points
  • Current components and practical manufacturing routes
04

Machine retrofit

Integrate current drives, guides, controls and mechanical interfaces around the existing equipment. The replacement must work within the machine’s functional and operating context.

  • Interface and installation planning
  • Prototype and functional checks within the agreed scope
  • Documentation of the implemented configuration
05

Obsolescence & lifecycle

Use the work already done to support the next replacement. Documentation, procurement and repeat manufacturing can become a planned lifecycle solution.

  • Production and inspection information
  • Spare-parts procurement and supply planning
  • Further development of repeatable replacement assemblies

Define the responsibility

A clear scope before changes begin.

Each project should state the scope of responsibility and whether a substantial modification or further conformity assessment may be relevant. Those questions belong in the technical discussion about the actual machine.

  • Identify who is responsible for the machine and its operation.
  • Record the original function and the planned modification.
  • Agree engineering deliverables, validation and interfaces.
  • Confirm any further specialist assessment needed for the scope.

Response times, restart dates and conformity-assessment services are not assumed. They require an explicit project agreement.

Next technical step

Tell us what has stopped working.

A fault description, machine identification and a few clear photographs are useful starting points. Agree a suitable channel before sharing confidential documents.
