Hägglunds motor repair – overhaul and certified testing

TFS repairs and overhauls Hägglunds radial-piston hydraulic motors — CA, CB, CBM, Compact and Atom series — in its workshop in Battipaglia (Italy), with test-bench certification and original spare parts, serving customers across Europe and the Mediterranean. As a Hägglunds partner, it guarantees work compliant with the manufacturer’s specifications across the full high-torque, low-speed range.

Why Hägglunds motors require specific expertise

Hägglunds motors are direct-drive radial-piston hydraulic motors, designed to deliver very high torque at low speed without a gearbox. This architecture (radial pistons, distributor, cam ring) requires dedicated disassembly, measurement and testing procedures. An incorrect overhaul compromises efficiency and durability.

TFS works on:

• CA / CB / CBM series — marine, industrial, heavy earthmoving
• Compact / Compact CA — integrated drives
• Atom — compact high-torque
• Complete Hägglunds Drive systems (motor + power unit + control)

The overhaul process

1. Diagnosis and complete disassembly
2. Measurement and dimensional check of components (pistons, cam ring, distributor, bearings)
3. Replacement of original spare parts and seals
4. Reassembly to Hägglunds specifications
5. Test-bench testing: flow, pressure, torque, seals — with documented report

When a Hägglunds motor needs overhaul

• Loss of torque or speed
• Abnormal noise or vibration
• Oil leaks from the seals
• Overheating
• Oil contamination (ISO 4406 class out of spec)
