MG330 graders working on mixed road construction and maintenance jobs depend on quick, repeatable blade-angle changes. When the circle drive develops play or noisy engagement, productivity drops and the operator may compensate with repeated control inputs. Vomeks supplies MG330 circle reverse gear components for workshop repair and field-service planning.
Send the MG330 machine serial number, the available catalogue reference and photos of the failed area. We can help separate a worm-drive problem from housing, shaft-support or adjustment-part wear before preparing the quotation.
On many MG330 repairs, technicians first inspect the bearing, bushing and sleeve supports before deciding whether the shaft, worm gear or worm wheel also requires replacement. This sequence helps reveal whether misalignment contributed to the damage.
The reverse gear converts motor input into controlled rotation of the grader circle. Accurate support of the shaft and correct gear contact are essential because movement at this point is reflected directly in moldboard positioning.
A grinding noise under load, oil leakage around the cover or a blade that drifts after positioning may indicate seal-area damage, loose supports or irregular gear contact. Continued use can widen the wear pattern and increase the number of parts required.
Vomeks can check MG330 housing, gear case, cover, worm gear, worm wheel, shaft, roller, flange, sleeve, shim, bushing and bearing requirements. Send one part number for a single replacement or a complete list for an overhaul quotation.
Clean the gear case thoroughly and inspect seating faces before assembly. Bearings should enter squarely, shims should be selected to the required clearance, and the worm pair should rotate without binding across the full circle range.
