What we've been up to lately ...

Trencher crack and final drive repair

This trenching machine hit some hard ground and damaged the chain drive and also cracked the bracket that holds the lift cylinder on. This job took us a few days as we started at one end of the machine and finished at the other. We ground out the cracked weld and used a vertical up weld with the mig using about 350 amps. We pulled the final drive down and repaired the damaged shaft in house. Just when we thought all was well with the trencher the coolant was contaminated with engine oil. We thought the oil cooler was a suspect with the Cummins diesel so we removed it and it was found to have a pin hole leak. We gave the motor a good service and the machine was back out digging after 3 days.
 

Scania engine change out 

We had a look at a truck with major engine damage. First we removed the heads and found quite extensive damage to the liners and also the block. The engine was cooked and the pistons had welded themselves to the block! We sourced a second hand motor for the client and when installing we found the radiator was completely blocked.  A radiator specialist tried to clear it but couldn't so we sourced a new one from Scania. This job was completed in a weekend.

  

Land cruiser Transfer case rebuild  

This transfer case was found to be generating metal when we were doing a service. One of the thrust washers was worn and we replaced it and put it back together with out having to replace any major parts just seals and gaskets. Also we changed all the fluids on the cruiser and repacked the cv joints and hub seals. This 75 series is a working ute and carries a lot of gear so the owner didn’t mind us using the best oils and coolant as it saves him money in the long run. We used a synthetic gear oil in the box and  transfer case to give the best possible protection. It makes the gearbox shift a bit harder on a really cold morning but with all the towing the owner does he doesn’t mind as the oil heats up pretty quickly. We have found synthetic 90 weight oil the best in these cruisers. We tried 85/140 but the shifting was way too difficult.



Remote area truck repair  

This Iveco had a sticking compressor valve and just wouldn't build up air. The client couldn't get to his job so we drove through the night and fitted a new compressor out in the bush. This truck is a real work horse and we since have been looking after it. We also changed out the Road Ranger gear box and the water pump.
