3. As I did an early AEC and did a diff swap, this is the way I would go. It was an 80 kph Sydney gov bus, found a diff and it became a 100 kph highway bus. Don't try to squeeze the extra from a tired engine, asking for problems. Especially crankshafts that have done millions of rotations.


In Atlanteans, its easier to change the angle drive gears to give you 100kph. Keep in mind though this will also affect first gear take off as it effectively makes first gear taller.

Hello everyone,
Hoping someone can help.
I took the bus up from Brisbane to Warwick recently. Climbing the range was interesting. As I approached the range, everything was fine. The temp was at its usual 75 to 80 degrees. As we started to climb I quickly ended up in first gear for the 7km ride up the range. I was down to walking speed with the engine just turning over without any strain and was surprised to see the engine temperature reduce to 70.
Once I came over the top and down a bit coasting in 4th I noticed that when I started up the small gentle rise up to Warwick itself, while still in 4th, the temperature started to rise. I ended up pulling over in the centre of Warwick to discover that the fan drive shaft that runs behind the motor and drives the pulleys that are connected to the radiator fan would rotate freely by hand but did not spin when the engine was working.
It turns out that the casing connecting the fan drive shaft to the rear of the engine timing casing had disintegrated as had the head of the shaft itself.
Does anyone have any idea of where I could even start to look for replacement parts. I don't even know what the correct terminology is for the broken parts. It is the passenger side end of the fan drive that enters into a teacup size and shape casing through which the toothed end of the drive shaft connects with cogs within the timing cover that extends forward of the engine.
Is there anyone out there that is parting out an old Atlantean?
Any help would be greatly appreciated.
Cheers
Gerard
