Steering gear spares — the items we are asked for most

Steering gear is the one hydraulic system where a small leak or a sticking valve becomes a detention item. The recurring demand is seals and seal kits, servo and proportional valves, pump internals, accumulators, filters and oil coolers. We source for the gear types common on Chinese-built tonnage — WUHAN IHI, Kawasaki and Mitsubishi — and can arrange repair or technical attendance in China when replacement is not the sensible option.

Seals are the cheapest insurance

Most of our hydraulic enquiries start with a seal kit: ram seals, gland seals, valve block O-rings. Material and hardness matter as much as dimensions — a correct-size seal in the wrong compound fails again in weeks. Send the gear maker, model, year and the seal position; if the original kit is unavailable we propose the equivalent and state the material specification.

Beyond steering: deck machinery and hatch covers

The same sourcing path applies to windlass, mooring winch, hatch cover and ramp hydraulics: pumps, motors, valve blocks, cylinders, hoses and fittings, plus pressure and temperature instrumentation. Where a hose assembly is the only issue, we can supply to length with the correct end fittings and test certificate.

What we can quote for you

  • Steering gear — ram and gland seals, servo and proportional valves, pump internals, accumulators, filters, oil coolers.
  • Power units — pumps, motors, valve blocks, reservoirs, level and pressure switches.
  • Deck machinery — windlass, winch, hatch cover and ramp hydraulic components.
  • Piping & fittings — high-pressure hoses to length, end fittings, quick couplings, test certificates.
  • Instrumentation — pressure gauges, transmitters, temperature sensors.

Brand and model names are used only to identify equipment compatibility. We are not an authorised distributor of these makers unless expressly stated; equivalents are always confirmed with you before quoting.

Frequently asked questions

Do you supply seal kits or individual seals?

Both. Complete kits are usually faster and cheaper than piece-by-piece sourcing; individual seals make sense when only one position has failed.

Can the work be done in a Chinese yard instead of shipping parts?

Yes. For steering gear and deck machinery we can arrange repair and technical attendance in Chinese yards, which is often faster than shipping a heavy component.

Are hoses supplied with test certificates?

Yes — hose assemblies are supplied to length with the correct end fittings and a pressure test certificate.
