Kookynet, I recently measured, confirmed by dealer that pitch (bolt) circle diameter is 208mm on 5 stud 2004 FG649 in Aus. Pilot hole "about 149mm". I needed dimensions just for a spare carrier.
one of the differences between 3 and 4 point mounts is that the 4 point will have to accommodate or constrain bending of the chassis.
When considering body roll, and its impact on the chassis, getting the centre of gravity within limits is a first approximation. The moment of inertia (watch the...
that's something of a relief to me. My belief is that rigidly fixing house to chassis (with torque free mount) behind the rear axle will in some circumstances create more roll of house and potentially adversely effect handling.
I hope this isn't "teaching grandmother to suck eggs". I haven't...
lots of useful info here. Thanks.
I'm part way through a 2004 FG (MWB) conversion and haven't tackled suspension yet. Though I've been thinking about it.
I had similar (expected) experience with driving plain cab/chassis about 800km. Even with tyre pressures way down it was bone jarring. There...
well there you go, the dealer knew all the time. 5 x 208 mm it is. I'll have more faith in my measurements next time.
Now to figure out why the holes in my laser cut steel (to hang spares on rear) leave the studs at a slight angle - grrrrrr!
trivial question time ....
can someone tell me the pitch circle diameter (the diameter of the circle which passes through the centre of all the studs, wheel bolts or wheel rim holes) for the 5 stud FG wheel.
I can measure it and arrive at "about 208 mm" but I suspect I'm a fraction out and...
they seem like that to me also, might have been in 1993 (I really don't know) but recent spec for chassis tensile strength is 450Mpa

Its a long time since I looked at steel in a lab but steel with yield strength between 340 and 690Mpa is...
I'm not much help with the repair but I've joined all those inspecting their chassis this morning and have a question about the pics. I think I can see something at the start of each crack, looks to me like a small weld. Am I seeing it correctly? Not present in mine (later model?) but could help...
I'm in the process of fabricating what is basically a three point mounting on a Canter.
At one point in the design process I made a simple meccano model to allow some observation of what may happen and aid discussion with Engineer.
A few observations came out of it. One was a decision to...
the Oka belongs to Peter and Margaret Wright, he has visited your work. I'm a refugee from a Coaster bus that was at risk of getting stuck once too often so I bought a Canter. I'll drop in and see you next time I'm in Yandina (some time in next 4 weeks). Peter sent me the photo to fire up my...
a "holiday snap" for John. The Coiled Canter on Fraser Is.
I bought a Canter chassis for conversion a few weeks ago. Another one in Brisbane. Mates keep sending me conversion examples. The diesel genie attracted some attention as well as the coils.
The Oka is well traveled throughout Aus...
