Repaired all in house

Stripped, measured and recorded — before a single part is replaced.

Gear case and main machinery overhaul to OEM specification. Every component is cleaned, stripped, assessed, measured and recorded before repair, replacement or refurbishment. Jacking presses to 600 tonnes — with the integrated support of our fabrication, welding, machining and painting departments, ABC repairs all in-house, 24/7.

That discipline is what OEM specification means in practice: the gear case that leaves the floor carries its clearance and measurement records with it, as part of a detailed QA package.

Strip, assess, measure, record

Overhaul starts with evidence. Each gear case is cleaned and stripped, then every running surface is assessed and measured against OEM specification — and the numbers are recorded before repair, replacement or refurbishment is called.

Fitting · presses

Press and pull, to 600 tonnes

Bearings, bushes and shafts come apart and go back together under controlled force. Jacking presses to 600 tonnes handle the press and pull operations of heavy overhaul — then each assembly is re-bushed and reassembled with full clearance records.

Seven departments behind every rebuild

Fitting never works alone. With fabrication, welding, machining and industrial painting on the same floor, a complete rebuild — case, gears, shafts and finish — never leaves the building. That integration is what allows ABC to repair all in house, 24/7.
