My goodness, I just had a look at the Dulux Overhaul photos. I could usually muster up some kind of response but that one left me speechless.

That could only be done by someone who truly couldn't care less.

I have emailed Oka Parts to ask about the skins and other bits and pieces. Hopefully hear back soon.

Thanks for the advice.

Alan.

Alan - Where are you up to with springs?
Did you find any places that have them - I have a lower GVM requirement, and potentially a leaf or two less.

Ideally perhaps out of Adelaide so they can be on a pallet?

Hi Holmz, thanks for that.

At this stage I think that the springs may already be upgraded to the bus specs. The top spring wraps around the pin as normal, then the second spring wraps around too (not as far), then the next 3 springs all terminate under the pin. After that, the springs then get shorter.

Can anyone confirm that this is the case?

Alan.

Alan, that's the standard set up.

But we broke both top leaves (of our ageing springs) after completing the top half of the CSR in 2007, and I found both the spring eyes on rear leaves broken when we got home after completing the Anne Beadell highway 2008.





So when we had the rear springs remade before our 2009 trip, I had additional third leaves fitted, extended around the eye at both ends. We also had the top 2 leaves of the front springs remade plus an additional 3rd wrap around leaf fitted.



With 20mm suspension pins (Peter Wright's kit), and subsequently fitting airbags all round (which share the load), we've had no further suspension problems (touching wood...).

The other consideration (which we didn't know about in 2009) is to have the top 2 leaves made 10mm thick rather than 8mm, for additional strength.

Apart from natural steel ageing, springs wear at the point where the end of a lower leaf rubs on the bottom of a higher leaf. That probably caused our first broken spring. To check, jack up the body so the wheels hang down and feel for wear grooves on the bottom of (mainly) the upper leaves. A mm or more is probably too much.

Thanks guys,

That makes perfect sense David. Your experience could have been a lot worse getting stuck in the middle of nowhere with broken springs.

Harry, would you happen to have Dennis Norton's phone or business details?

Like this Alan?




Broken 16mm shackle bolt north of Drysdale Station on the Kalumburu Track, returning from the Mitchell Falls, before we upgraded the springs and suspension bolts and fitted airbags.

It was hot work and took the two of us the best part of a day to replace the bolt, jacking the body up and getting the axle back into alignment.

Another case for ensuring the suspension is as tough as possible, it could have happened on the top of a CSR sand dune, or in a rocky creek bed...

You'll notice that all our suspension failures have been on the front ends of the rear springs. That makes sense since they do most of the pushing and pulling as well as lifting.

It makes sense as the rears seem to pivot via a shackle.
