i have several questions

is it possible to convert 660to 700 (on some truck it is very easy to flash firmware from euro 4-euro 5)

why

why acandinavians frequently used tag axles with double tires

how often do you use the self steerasble tag axles .....
I saw a lot of used Scania with steerable tag axle

660 to 700. I have no idea.. Sometimes it´s only firmware changes and sometimes there is a lot of differences.. Scania 460 to 530 same engine everyones thinks but actually there is differents on pistons and on piston rods..

If u have single tires u can not have same weight on drive+tag.

The transmissions are not fully synchronized in big trucks in this country, except for a few imported from northern Europe, I have never seen one of those here. Double clutching is used by some, floating by others, neither of those work for the fully synchronized transmission.

You can float gears in a synchronized tranny. I've done it, but there really is no need to.

Today my (our..) Volvo has gone 30000km and is running like
The only thing i miss is the clutch pedal and gear stick...

Interesting, your spelling is mostly better than many of us that are afflicted with American English.

We often spell k sounds at the end of syllables as ck, e sounds are another rule

I like your new truck, and 40 more horsepower would probably make little difference in how it runs, if it's anything like our trucks, some trucks that look identical don't perform that way at all.

You are correct, but it is much nore difficult with a new transmission than old worn out ones, and there isn't much reason to, the gears have to go into mesh and it takes time to do that, it's quicker with the clutch.

The farm tractors I drove were synchronized from forward into reverse: great for loader work on slippery surfaces.

is it the law that says: the driving axle + tag with single tires = 18tona, a driving axle + tag with double tires = 19tona for 19 tons you must have air suspension

interesting here in croatia are not looking, even though the law says the same
here are tolerant of 19 tons and mechanical suspension and single tires on tag

Actually, yesterday i passed (not fast but i still went past him ) a DAF XF430 2 axel truck with a 3-axle trailer with german plates i carried 60,5 mtons and his legal weight is 42mtons i think? Up a steap (spelling? :S ) hill ("Skuleberget" in Sweden). I was going 56km/h and He ~50km/h.

I don´t know his actual weight... but his legal weight is 42 and mine is 60.. And i was a little over and probably his also.

What i can tell you fore sure is that are fuel consumption as decreased with the 660 compared to the 420
Click to expand...

his legal weight in german and other parts of europe is 40 m ton
only in scandinavia(7axles 60t) holand(5=50tons) itally(5=44 they tolerate 50) and uk(5=40 6=44) is diferent

do you know how much is the hill gradient? is it about 5%

No, 700 has different pistons and multiple injections, maybe some other changes also. But you can program 660 to 750 or maybe more if you want to..

long ago in the 70's we had length restrictions. Once they were lifted you see almost no cab over engine design trucks like you are used to seeing.

Yes our gearboxes are unsyncronized although we are seeing more and more automatic transmissions every day.

Most our tractors are three axle and most our trailers have two axles but you do see almost any number of axles for specialized transportation. With 5 axles we can gross 40 ton (us) it breaks down as 12,000 pounds on steer axle. 34000 pounds on each set of tandem axles. If your trailer has a spread of 10 feet between the ales you can put 40000 pound on them but still not gross more than 80,000 pounds.

Front brakes on tractors were mandated on any tractor built after january 1, 1982 although most trucks were being built with them in the late 70's

most the company owned trucks will have 10 speed transmissions here although as mentioned automatics are becoming very common. I expect we will see almost all automatics in the next 5 years in company owned trucks. Most of the owner operator trucks will have more gears, either 13, 15 or 18.

funny guy, wasn't it you who was trying to convince me that a spread axle reefer can't be loaded heavier then a tandem even if it was a spread? The things you said on that post and now this post don't make any sense and when i gave you a explanation you didn't reply hahaha wow.

On the Interstate Highway system, the limit is 80k without permits, having a spread allows some flexibility on how the trailer is loaded, you don't have to have 12 on the front, 34 on the drives and 34 on the tandems with a spread axle, and they do ride better.

I thought the original volvo software

thank You for your reply

and do you know maybe when Scania will produce new V8 and do you know
whether to be the egr or scr ,and how much torque
is probably be 16.4L v8 with 130x154 or 155mm xpi( common rail ) vgt ,but 720 hp from 16.4L and egr difficult to go .

from my knowledge that it will have, or 3200 or 3400 of the torque
