Four ways we keep iron moving.

Excavators, linkages, loader booms, pin replacements, tractors and hydraulic cylinders. Unscheduled downtime is a luxury few can afford, so the work is built to last and turned around fast.

Worn pin bores don't need a lowbed trip. We bring the rig, weld up the bore, machine it true and press in new bushings or sleeves on site. Damaged pins, bushings and linkages are repaired or made new in the Langley shop.

  • Up to 12"bore diameter
  • Yorkline boring machines
  • Boretechautomatic bore welders
  • Wells Cargotrailer mounted, ready to roll

Questions from the yard

Do you repair hydraulic cylinders?

Yes. Everything from a basic reseal to a complete rebuild, or a modification. A nearly 40-point inspection finds the root cause. We handle cylinders from excavators up to 1200 size, compactors and balers, cranes, tractors, boom lifts and loaders.

Do you do line boring on site?

Yes. The mobile rig is mounted on a Wells Cargo trailer and repairs bores up to 12" diameter with York line boring machines and Boretech automatic bore welders. We carry hydraulic jack cylinders and a compressor to press fit bushings or sleeves on site.

Can you make new pins, bushings and parts?

Yes. Our Langley shop has a full conventional machine shop and CNC lathe for new parts, modifications, rebuilding worn surfaces back to original size, and custom machining.

Do you sell thumb cylinders?

Yes. We build hydraulic thumb cylinders in house in 4" and 5" bore, with precise tolerances and more robust tube walls. Custom cylinders can be built or modified to suit.
