Fleet Servicing & Maintenance in the Illawarra
At BITR Enterprises, we look after fleets of trucks, trailers, buses and floats across the Illawarra with scheduled servicing and preventative maintenance built around how your vehicles actually work. Servicing can be completed in our fully equipped Unanderra workshop, or at your depot or yard where practical, so vehicles spend less time off the road.
We repair and service all makes and models of trucks, and we are a Detroit Dealer for parts and warranty repairs as well as an Authorised Engine Rebuild Centre. That means logbook servicing, warranty work and larger engine jobs can all be handled by the same team that knows your fleet.
Call us on (02) 4231 4143 to talk through a servicing schedule for your fleet.

What a Fleet Service Includes
- Scheduled and logbook servicing with oil, filter and fluid changes
- Brake, clutch and driveline inspections under load
- Electrical, charging, lighting and warning-light checks
- Air system, leak and suspension inspections
- Trailer inspections, including brakes, hubs and lighting
- Written inspection reports so upcoming repairs can be planned
Planned Maintenance Reduces Downtime
Most heavy vehicle breakdowns give warning signs long before they stop a truck. Regular inspections let us catch worn brake components, weeping seals, chafed wiring and air leaks while the vehicle is already booked in, rather than on the side of the road mid-run.
We work with operators to set service intervals by kilometres, hours or calendar dates, and keep records so you can track spend per vehicle and stay on top of compliance obligations. When something does go wrong between services, our 24/7 mobile team can attend the vehicle where it stops.
