semi trailer repairs B double Jaltest Logodownload castrol image



Deano's Diesels is a small business committed to the repair and maintenance of heavy vehicles.

We are 100% mobile with almost all the gear to get you back on the road.

Est. in 2011. I wanted to provide a service for owners of trucks in East Lake Macquarie to have there vehicles maintained by a qualified heavy vehicle mechanic. I could see there was no dedicated licensed business in this area servicing heavy vehicles at that time, so that's roughly how it started.

It also allowed flexiblilty with the time I spend with the family.


We repair most makes of trucks  American, Jap, European. (and Asian)

We use Jaltest diagnostics software (among the first in Australia to import and use this software ).  This provides communication with the latest models of truck, bus and light commercial vehicles. It covers the majority of USA, JAP, EURO trucks, Cummins, Detroit, Caterpillar, Benz ..... Jaltest was mostly European but is now a strong performer in the American market. It is a good all round diagnostic tool. It is not perfect but can perform most tasks. 

I've 20 odd years in fleet maintenance and Dealerships,  covering lots of different machines from the humble Victa, lift trucks, excavators, wheel loaders, rubbish compactor units, vacum trucks, sweepers, cranes, Franna cranes, Earthmoving....

We do onsite repairs inculding suspension, brake, engine, air leaks, PTO, Basic Hydraulics, replacing Diffs, fuel pump installs, Basic electrical work, Clutch adjustments replacements, Service work, Vehicle inspections (not RMS defect clearance as RMS won't let mobile workshops clear).

We have a competitive fixed hourly rate for day work and night work.

After hours breakdown is available (rates apply). 0437425407

We service South from Mt White, Central Coast. North to Buludelah.  West to Broke Cessnock.
