A vacuum truck that won’t pull suction, won’t dump, or leaks around the tank is a truck that can’t earn. Ames Hydraulics does vacuum truck repair in central Iowa on septic vacs, industrial vacs, oilfield vacs, and portable-restroom pump trucks. Vacuum pumps, hydraulic hoist cylinders, PTO drives, tank welds, and the plumbing that moves everything. Free pickup within 60 miles of Ames.
What Actually Fails on a Vac Truck
Most vacuum truck repair we see falls into a few reliable areas. The vacuum pump loses efficiency and won’t hit vacuum. The hydraulic hoist cylinder that dumps the tank leaks or won’t lift. The PTO drive to the pump slips or wears. Tank welds crack from repeated dump-cycle stress and years of corrosion. Product valves, hoses, and plumbing get chewed by whatever the truck hauls. We handle every one of those in the same shop — hydraulics, welding, mechanical, and PTO drive work under one roof.
What We Repair
- Vacuum pumps — Masport, Jurop, Fruitland, Wallenstein, and PTO-driven rotary vane pumps rebuilt
- Hydraulic hoist cylinders that lift the tank — resealed, rebuilt, or replaced
- PTO drives that turn the pump — shafts, U-joints, and mounts
- Cracked tank welds on carbon-steel and stainless vac tanks
- Product plumbing, valves, and hoses
- Manways, sight-glasses, and vacuum-relief hardware
- Running gear underneath — axles, brakes, and frame
Septic, Industrial, and Oilfield Vacs
Septic vacs and portable-restroom pumpers see the mildest environment; industrial vacs pull slurries, sludges, and hot loads that eat pumps faster; oilfield vacs live in the worst environment of all with abrasive and corrosive fluids. Vacuum truck repair is the same fundamental work across all three, but the pump wear cycle is very different. We size rebuilds and parts to the actual service the truck sees, not a generic replacement.
Tank Welding — the Big One
Cracked tank welds are one of the most common reasons a vac truck comes to us. The tank flexes every time it fills, dumps, and drives, and eventually the welds around the manways, the bulkhead ends, and the frame mounts crack. Welded and reinforced properly, those cracks become stronger than the surrounding metal. Left alone, they end with a tank that leaks in traffic or on the customer’s property. That’s not a good day for anyone.
PTO and Hydraulic Drives
The PTO drive that turns the vacuum pump is a common failure point — shafts wear, U-joints go, and mounts crack. Some newer vac trucks use a hydraulic drive to the pump instead, which brings its own hydraulic-pump-and-motor rebuild work. We do both, and doing both properly is why our vacuum truck repair holds.

Pump Rebuilds Versus Replacements
A tired vacuum pump doesn’t have to be replaced — most Masport, Jurop, Fruitland, and Wallenstein pumps can be rebuilt for a fraction of the cost of new. Rotors, vanes, end plates, and bearings are the wear items; we tear the pump down, measure everything, rebuild what’s within limits, and pressure-test the assembled unit. A proper vacuum truck repair pump rebuild holds as long as new; a bad one comes back in six months. That’s the difference between a real hydraulic shop and a parts-swap.
Turn Time and Cost
Most vacuum truck repair is turned in a week or less if the truck comes in whole. Cylinder reseals depend on seal-kit availability — usually 24 to 72 hours. Pump rebuilds are typically 3 to 5 days depending on parts. Tank welding is a day or two per weld area. We quote every job up front and stick to it, so you can plan dispatch around a real completion date.
