At Superior Diesel Maintenance, we offer a full range of mechanical services for vehicles and equipment across Tamworth and the surrounding region. From diesel and truck mechanical work through to mobile diesel servicing, mobile truck repairs, plant and mining equipment repairs, truck and trailer repairs, fleet maintenance, diagnostics and 24-hour breakdown assistance, our team covers the work heavy vehicle owners and operators need most.
Every service is available from our Westdale workshop or on site through our mobile units, whichever suits your situation better. Workshop jobs suit scheduled servicing, longer repairs and anything that needs the full range of equipment on hand, while mobile callouts keep trucks, utes and machinery working where they are instead of losing a day to towing and travel.
