Cabovers

FMX is a greate truck, they say that they wanna make new VHD on the same base. Yep, I'd like to get hood to better engine access when truck is id mud) LOL

 

one thing i dont like is:

front axle is zf and rear are meritor/volvo

so too many different parts , i know those rears dont exist in small version(to adopt for use in front axle) but still i think i would not take volvo with all wheel drive because of that

 

about steering assistant, I remember old '92 taurus with system that changes PS sencetivity. Seems to me they use it on trucks now

 

Recently had one in the shop, the driver was jacking up the cab, it went overcenter and impaled the windshield on some shop equipment. Driver was none too happy, had to overnite a windshield in.

 

Most times it was a tool box, or a cb , or something th driver owned!

 

Duty free bottle of whiskey left on the top bunk! Guilty!

 

scania dont make powered front axles either,in the past it was sisu know its raba
the best planetar reduction axles is m.a.n./mercedes ,they are relaible easy to repair and dismantle,
comparing to scania rbp830 where hubs constantly leak and its a PITA to dismantle them..

 

they make them since begin of 4series , parts are shared with 11.5t small hub reduction axle, you are maybe confused by different hubs , but they use old hub which was used on rbp/rp730 , they probably dont find that developing new axles would be cost effective , i saw also on some early versions of tga that they use older and new axles at same time

also new rwd scania trucks use hub reduction ratio of 4.21 and updated stronger halfshafts, while awd trucks use old hub ratio of 3.81 ,

you are right before they were sisu and transfer gear was MAN , now it is ZF/steyr ,(gt/gtd890 is zf vg1600 , gt/gtd900 is vg2000, gt950 is vg2700 )

now seems that vw wants scania and man to use as much as possible components from in-house to buy less from other manufacturers , so scania would again use man transfer box in future , and one lighter differential for weights up to 40t, man would use scania manual gearboxes and they will develop hybrid solutions together

i dont understand what did you want to say by this ....did you say that raba copy sisu? i never saw raba with front wheel drive so i dont know how they look , but it make sense....there is small number of old 2/3series with front wheel drive i always wondered where they get parts

i would agree that best are old zf "europa achse" used on mercedes and man and currently used on mercedes , but new man dont use them many people confuse that man with "europa", and those man are crap i dont know how they were so crazy to make so stupid decision to let axles to mercedes , there is nothing ugly to hear as when you push throttle and hear impact in power devider on man and they are heating a lot

well i dont care how complicated are they for repair since it is not my job but i look at how reliable they are and availability of parts , since they are most common there is no problems with parts

those old rbp/rp830 have pretty fast ratio of hub only 2.83 , back than hl/hd7 had almost 4 ( i dont remember right number of teeths now, but it was close to 4 - 3.95 or something , most popular diff ratio on tippers was 5.937 and inside diff it was 27:18, now mercedes use same number inside and two different hub ratios

and that fast center of diff with that slow hub , was by me main advantage of hl/d7 over rbp/rp830 back in 1970-1971 when both were released ,this take strain from center of diff and halfshafts ,that allow axle to take lot of abuse (even steering while difflock in engaged) offer better traction less tire hop and wheelspinning
