got a workshop manual.if u live in perth u can borrow it.([email protected])

...to line everything up for top dead centre:

*the mark on the left (looking at engine from radiator side) cam gear will be pointing northwest

*the mark on the right cam gear will be pointing north east.

*the mark on the crank shaft gear will be souteast

your timing belt's marks will then all match up with those.

then to do the timing:

*get engine up to temp

*unplug the TPS (throttle position sensor)

*loosen 3 bolts holding the CAS onto the engine enough to move it slightly

*hook up your timing light to the loop at the back of the engine or the no. 1 coil/plug (as well as the battery)

*point the timing light at the harmonic balancer and press your button

*the light should be matched to the 4th line (yes, that's 15 degrees - first line is 0, second is 5 and so on)

*adjust CAS until the timing light flash lines up with 15 degrees

*tighten cas, plug in TPS and away you go.

ah ok kewl so theres timing marks on the head for the cams and a promiate mark on the block for the crank timing is there ??

so with the timing theres no need to go into a dianostics mode or anything. Unpluging the tps sounds alittle wired for me all other cars i have timed at work have a produre to do base timing. Is that the produre that the workshop manual states i am not saying u doing know what your talking about just sounds strange to me thats all

thanks

yeah dude, unplugging the tps is suggested in the workshop manual - that's how it gets it's 'base' timing.

    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position. 
    • You talking about the ones in the photo above? I guess that could make sense. Fixed (but flexible) line from the point up above down to the hubcap thingo, with a rotating air seal thingo. Then fixed (but also still likely flexible) line from the "other side" of the transfer in the hub cap thingo up to the valve stem on the rim. A horrible cludge, but something that could be done. I'd bet on the Unimog version being fed through from the back, as part of the axle assembly, without the need for the vulnerable lines out to the sides. It's amazing what you can do when you have an idea that is not quite impossible. Nearly impossible, but not quite.
