CAT Pump Rebuild Services in Australia – Maximise Longevity with MultiTorque 2025
When high-pressure performance is critical, few brands rival the engineering of CAT Pumps. But even the most durable equipment eventually shows signs of wear. Whether your CAT pump is losing pressure, leaking oil, or suffering from internal damage, a CAT pump rebuild can restore it to full working condition—saving you money and preventing downtime.
At MultiTorque, we specialize in CAT pump rebuilds for a wide range of industries including mining, agriculture, industrial cleaning, oil & gas, and more. With branches in Brisbane and Perth, our rebuild services are trusted across Australia for speed, reliability, and precision.
What Is a CAT Pump Rebuild?
A CAT pump rebuild goes beyond basic servicing or seal replacement. It involves a complete teardown, inspection, refurbishment, and reassembly of the pump using genuine CAT components. This process restores your pump to “as new” performance at a fraction of the cost of replacement.
Rebuilding is ideal for pumps that:
- Have excessive runtime and wear
- Are leaking from multiple points
- Produce irregular pressure
- Have noisy or worn crankshaft assemblies
- Are critical to your operations and can’t be replaced quickly
Signs Your CAT Pump Needs a Rebuild
Not sure whether a rebuild is necessary? Watch for these signs:
- ⚠️ Oil or water leaks from multiple seals
- 🧯 Erratic or reduced pressure output
- 🔊 Unusual vibration or noise
- 🔥 Overheating crankcase
- 💧 Contaminated pump oil (milky or dark)
- 🕳 Visible wear on plungers or piston rods
Catching issues early and rebuilding at the right time can add years of life to your CAT pump and protect your overall system from further damage.
What’s Included in a CAT Pump Rebuild by MultiTorque?
At MultiTorque, we don’t just swap out parts—we deliver full, professional-grade CAT pump rebuilds using manufacturer-approved specs and high-precision tools.
Our rebuild process includes:
🔧 1. Full Disassembly & Inspection
We dismantle your CAT pump completely, inspecting each component including:
- Crankshaft
- Bearings
- Connecting rods
- Plungers or pistons
- Valve assemblies
- Seals and O-rings
🧼 2. Ultrasonic Cleaning & Component Restoration
Parts are deep-cleaned, degreased, and checked for micro-cracks or corrosion. Salvageable parts are reconditioned, and any worn or out-of-spec components are replaced.
🛠 3. Replacement with Genuine CAT Parts
We only use OEM CAT parts, including:
- Valve kits
- Seal kits
- Ceramic plungers
- Gaskets
- Crankcase components
- Unloaders and more
⚙️ 4. Reassembly & Precision Calibration
The pump is reassembled with correct torque settings, tolerances, and fluid levels. We test oil levels, verify alignment, and balance the crankshaft.
💡 5. Performance Testing & Certification
Each rebuild includes pressure testing, flow testing, and system calibration to ensure your pump is performing at factory-rated specs.
Why Rebuild Instead of Replace?
💰 Cost Savings: A CAT pump rebuild costs significantly less than a full replacement—especially for high-spec models or integrated systems.
🔁 Extended Life: Rebuilding gives your pump a second life, often adding 3–5+ years of service depending on use and environment.
⚙️ Custom Upgrades: Rebuilds offer the perfect opportunity to upgrade seals, materials, or performance specs to better suit your application.
🌱 Sustainability: Rebuilding reduces waste and supports a circular maintenance economy—ideal for ESG-conscious operations.
