SAA6D125E-5 6217-01-1310 Engine Assembly by Tatan Overview
The SAA6D125E-5 6217-01-1310 Engine assembly manufactured by Tatan is a heavy-duty inline 6-cylinder, 11.04-liter electronic common-rail industrial powerplant belonging to our Diesel Engine Assembly classification. Engineered specifically for Komatsu WA470-6, WA470-6A, and WA480-6 24-ton mining wheel loaders, replacing your failed or overheated engine with a Tatan complete turnkey assembly eliminates common-rail starting delays, restores 204 kW (273 HP) high-stall torque converter power, and cures excessive crankcase blow-by across demanding quarry, cement plant, and earthmoving applications.
Driving both the transmission torque converter and the loader’s hydraulic main pump, this SAA6D125E-5 6217-01-1310 Engine delivers fluid to the WA470-6 main control valve, incorporating an induction-hardened forged steel crankshaft, mid-stop wet cylinder sleeves, internal gallery-cooled pistons, and a wastegated turbocharger, ensuring 100% direct bolt-on installation with flywheel housings and chassis mounts.

Supported Construction Machinery Brands & Powertrain Lineup
In addition to Komatsu, Tatan manufactures replacement complete diesel engines, cylinder blocks, and overhaul components for major heavy equipment builders:
24-Ton Mining Wheel Loader Powertrain Standards & Industrial Engine Engineering
Operating 24-ton wheel loaders with 4.5 m³ buckets under constant shuttle loading and torque converter stalls requires high transient torque rise. When repowering with the SAA6D125E-5 6217-01-1310 Engine, Tatan supplies complete industrial diesel units engineered with mid-stop wet sleeves, gallery-cooled pistons, and pre-matched sensor harnesses for diversified heavy equipment fleets:
⚡ High Stall Torque Rise
Electronic fuel mapping delivers instantaneous common-rail pressure during rock pile crowding, preventing engine stall.
🛡️ Anti-Cavitation Wet Sleeves
Heavy-wall centrifugally cast alloy iron liners with viton packing resist high-frequency ultrasonic cavitation and wall pitting.
❄️ Gallery-Cooled Pistons
Internal oil-cooling galleries reduce piston crown temperatures under continuous 204 kW full-load aggregate scooping.
Application Scenarios & Buyer Value
When upgrading or replacing your wheel loader powerplant with our SAA6D125E-5 6217-01-1310 Engine, buyers achieve maximum operational uptime and flow control:
| Application Scenario | Value Delivered to Buyer |

SAA6D125E-5 6217-01-1310 Engine OEM Diagnostic & Troubleshooting Guide
Use this OEM manual diagnostic guide to troubleshoot SAA6D125E-5 common-rail engine symptoms on your Komatsu WA470-6 wheel loader:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Hard starting / long cranking when engine is hot (Error CA559) | HPCR fuel injector internal spill-valve control seat micro-wear causing excessive back-leakage, dropping rail pressure below 35 MPa cranking threshold. | Replace with Tatan 6217-01-1310 complete engine assembly fitted with brand-new calibrated Bosch common rail injectors. |
| 2. Engine oil turns milky & coolant level drops in reservoir | 125mm wet cylinder liner lower viton O-rings hardened or cavitation pitting eroding through the cylinder sleeve wall under high vibration. | Install Tatan new engine with factory-seated heavy-wall wet sleeves and dual-sealing viton liner packing. |
| 3. Heavy black smoke & engine bogging during pile crowd | Cooled EGR valve stuck open by carbon soot or wastegated turbocharger actuator diaphragm leak, causing boost pressure loss (< 185 kPa) under stall. | Install Tatan turnkey complete engine; verify intake manifold pressure sensor reading and flush charge-air piping. |
| 4. Excessive blow-by mist spouting from crankcase breather tube | Top keystone compression ring groove carbon-welded or cylinder cross-hatch polished away under continuous 204 kW quarry cycle load. | Install Tatan brand-new engine assembly with gallery-cooled pistons and plasma-coated top compression rings. |
Transport Packaging & Certified Manufacturing Standards
Complete 11.04-liter loader diesel engines require absolute vibration and moisture isolation. Every Tatan SAA6D125E-5 6217-01-1310 Engine shipment undergoes anti-corrosion fogging, heat-sealed plastic wrap, and solid timber export crating:
