Contact Our Export Team for MG400 Circle Gear Parts

The MG400 is commonly assigned to demanding roadwork where the blade circle carries sustained load during cutting and spreading. A worn reverse gear can create backlash at the moldboard and slow down accurate repositioning. Vomeks supplies MG400 components for planned overhaul and urgent breakdown repair.

Part verification: catalogue reference, serial number and component photos can be reviewed before quotation.

Supply choice: OEM or high-quality aftermarket options may be checked according to availability.

Heavy-Duty MG400 Application

Continuous grading on compacted material can raise the load on the worm wheel teeth, shaft bearings and housing supports. The assembly must hold alignment while still allowing smooth circle rotation under changing blade pressure.

Wear Components to Inspect

Begin with the worm gear and worm wheel contact surfaces, then inspect the shaft, roller, bearing and bushing for movement. Flange condition, sleeve wear and shim range should also be checked before the gear case is closed.

MG400 Damage Scenario

Chipped gear teeth or a repeated knocking sound during reversal often follows operation with excessive backlash. If fragments circulate inside the housing, the bearings and seating surfaces may also be damaged, turning a gear replacement into a broader rebuild.

Ordering MG400 Parts

The supply range covers housing, gear case, cover, worm gear, worm wheel, shaft, roller, flange, sleeve, shim, bushing and bearing. Use the catalogue number whenever possible; otherwise provide clear dimensions and photos alongside the serial number.

Overhaul Recommendation

Replace contaminated lubricant and remove every metal particle before fitting new components. Check shaft runout and bearing seats, then set the gear engagement according to the service requirement rather than reusing the previous shim arrangement automatically.
