Mobile Hydraulic Repair — Hoses, Cylinders, Pumps & PTO

Blown hoses, weeping cylinders, dead PTOs — hydraulic repairs where the machine or truck is working.

Hydraulics fail at work — a dump box that won't lift mid-pour, a hose that lets go at a Maple Ridge gravel pit, a crane that drifts, a liftgate stuck half-way at a Port Kells dock door. Langley Mobile Truck Repair repairs hydraulic systems on trucks and equipment across the Lower Mainland, on site, so the job you're on doesn't die with the hose.

We handle wet kits and PTO drives on dump trucks and roll-offs, cylinder and valve problems, pumps, liftgates, and the hydraulic circuits on the machines that work alongside trucks. Failed hoses get replaced with properly rated line, contamination gets flagged before it kills the next component, and fluid loss gets found — not topped up and forgotten.

Dump Truck Won't Lift? Three Checks Before You Call Anyone

Three thirty-second checks before you call anyone, and why a raised box gets blocked first.

  • Oil level with the box down, PTO engagement, pump load
  • No PTO is usually air shift, cable or a stuck valve spool
  • All three get fixed where the truck is sitting
  • A raised box that will not lower gets blocked before anything else

What we handle on-site

  • Hydraulic hose failures — replaced and routed properly on site
  • PTO and wet-kit diagnosis and repair on dump trucks and roll-offs
  • Cylinder repairs — drift, leaks, seal failures
  • Pump and valve diagnosis and replacement
  • Liftgate hydraulic and electrical faults
  • Dump box, hoist and tarp system problems
  • Fluid and filtration service, leak tracing, contamination checks

Trucks and the machines beside them

Lower Mainland work is mixed work: the same yard runs highway tractors, dump trucks, an excavator and a skid steer. We service the hydraulic side of all of it, which means one text covers the whole yard instead of three different service providers. For machine-side mechanical work beyond hydraulics, see heavy equipment repair.

Hydraulic emergencies are also where our no-markup parts policy pays visibly: hose, fittings, cylinders and pumps priced at exactly what the supplier charged, with the receipt in your invoice — at $130/hour for the labour and not a dollar of parts margin.

Hydraulic Repair — FAQs

Who can I call if my dump truck hoist will not come down in Langley or Surrey?

Langley Mobile Truck Repair, 778-887-5216, 24 hours. A raised box that will not lower is a hazard as well as a breakdown, so block or prop it and keep everyone out from under it until someone is there. We come to the pit, the jobsite or the yard across Langley, Surrey, Abbotsford, Cloverdale, Maple Ridge and Delta, and we carry hose, fittings and PTO and valve parts. Most hoist faults are a PTO air shift line, a control cable, a stuck valve spool or a blown hose, and all of those are fixed where the truck is sitting at $130/hour.

My dump truck will not lift. Where do I start?

Work back from the simplest thing. Is there hydraulic oil in the tank and is it up to level with the box down? Then PTO: does it engage, and can you hear the pump load? A PTO that will not engage, an air shift line that has failed, a control cable off its lever, or a stuck valve spool will all give you a hoist that does nothing. A pump that has lost its prime or a blown hose usually announces itself with noise or a puddle. Text 778-887-5216 with what the truck does when you pull the lever and we will bring the likely parts.

My dump truck hoist will not come down. Is that dangerous?

Treat a raised box as dangerous until it is safely down or properly propped. A box that will not lower is usually a stuck control valve, a bound cylinder, debris in the way, or a load hung up at the front of the box. Never get under a raised box that is not blocked. Do not drive it raised, and watch for overhead lines. This is a normal mobile call and we would rather come to a raised box than hear about a dropped one.

My dump truck tailgate will not open or the dogs will not release.

Tailgate latches, the dogs, are usually mechanical or air operated. Common causes are a seized or bent latch pin, worn or misadjusted linkage, a failed air cylinder or a broken air line, ice in winter, or simply load pressure holding the gate shut. Do not stand behind a loaded gate while working on it. We free, adjust or replace tailgate latch gear and air cylinders on site, and this is a same visit fix far more often than not.

Do you carry hose and fittings?

Text 778-887-5216 with your location, what machine or truck it's on, and a photo of the failed hose end if you can get one safely — that photo often means we arrive with the right replacement made up. Roadside and jobsite hose calls are among our fastest turnarounds because the repair itself is quick once we're there.

My dump box is slow or won’t lift loaded. What is that?

Slow-under-load usually points at a worn pump, a relief valve setting, restricted suction, or air in the system — occasionally just badly low fluid, which itself means a leak. It's a classic on-site diagnosis: pressure-test, isolate, and repair at the truck rather than losing the truck to a shop queue.

Do you make up replacement hoses?

We stock common hose and fittings for emergency repairs, and the Langley–Surrey corridor's hose shops can make up anything beyond that same-day. Either way the hose that goes on is rated for the circuit it serves, routed and protected properly, and billed at supplier cost.

Can you fix a leaking cylinder on site?

Frequently, yes — seal kits and gland work are doable at a yard or jobsite with the machine safely supported. Heavily scored rods or damaged barrels need machine-shop time; if that's what we find, you'll get photos, honest options and help getting the component where it needs to go.
