I've also thought that right hand thread on right side and left hand thread on left side would loosen. But I have no real way of checking and figure the designers knew what they were doing. Examination of my failed lug/stud suggested the first one was loose enough for the wheel to move and flex...

The lug/stud has a "collar".

from first principles (not experience of wastegates) I think the control relies on pushing the wastegate to a fixed position to achieve the set point boost. Which means its a very limited control scheme. Probably why in more advanced vehicles wastegate control may be from the ECU. The actuator...

are there any of those radiating brown stains on the driver's side? Quite likely over-tightening caused sufficient damage. Fracture face may help. It doesn't take much once the conditions for starting a crack change. My Aus passenger side are left hand thread ..... had to think about...

seems like good logic to me John. Pity about the non adjustable arm.

good to get home in one piece. Do you have a very close up of the fracture face of the stud that broke while driving? Include the bevel round the hole in the wheel. Can't really see clearly but the one that broke during nut removal looks like the nut was sufficiently seized on the thread and a...

sorry about the double post. A bit slow from Nepal. Even worse, a senior moment and my edit didn't work. I meant to say Amesz thingy would work. I'm struggling with how an adjustable arm would effect the set point.

just tilted the cab and had a look at my FG. I think the guy that wrote the manual must have been dreaming. At least now I know why the actuator arm has a kink in it. :-) The actuator is nicely sealed so no real chance of messing with the spring. Sorry for red herring. Amesz thingy would...

For 4D34 Engine in 2005 FG Australia, section E15 page 7 of manual. Boost pressure standard value "-", limit 36kPa (270mm Hg) at 3700 rpm, no load, air temp 20 deg C, air pressure 100 kPa (760mm Hg). Correction required for different air temp and rpm deviation. Nothing about altitude or other...

Edit ... the post I quote below seems to have disappeared. But my bit about how the spring operates is probably still relevant.... also consistent with the adjustable arm in Kerry's link. I'm talking of the actuator. There is effectively "no" flow to/from the actuator. Just the very little bit...

something niggling in the back of my brain ..... my understanding of the wastegate is when the boost pressure exceeds the pressure required to overcome the spring the gate will open and dump air from outlet of turbo reducing the pressure which allows the spring to close a bit. Much like a SCUBA...

I rationalised that with fixed mounts towards the front the body was subject to the average twist (and roll) of the chassis relative to the road. If fixed mounts at the rear the body was subject to the twist nearer the rear wheels. Hard to get one's head around, I suspect there's less body...

today I thought to remove the dead (formerly) flying insect that had somehow got past the defences and was behind the clear plastic of the speedo and other instruments. After dismantling the dashboard I had a look at the ECU. I should have realised earlier that the Zexel fuel pump on my engine...

Nice list Iain. I know of someone who transfers anything from glass jars into plastic ones, in the supermarket car park. We've had a couple of screw lids come off. Nothing worse than end of a tiring day faced with curry paste all over the show. A place for everything, everything in its place...

http://www.epicycles.com yup, that's me, hopefully now back to Iain's Unimog build

the cooling air fan situated vertically in the front of the Aluminium box pushes air into the box which then exits through the outer pipe surrounding the exhaust. The Al box is under pressure. Only yesterday did I observe the fan turning in the right direction to pressurise the box after I...

just a thought from recent experiences with FG, atmospheric pressure at 1,100m (Bend, Or) is about 90kPa, which is about 10% lower than sea level (100 kPa). I don't know about relative humidity or ambient temperature at Bend. All three have the potential to effect turbo boost. I don't know...

I guess you really didn't want the question answered ......
