question on the white DM-800 . fuel tanks mounted on frame ( weight transfer?). exhaust brought back towards weight box = different . question is - what/why the unit on air cleaner intake pipe under intake bonnet???  a precleaner  or a type of turbo to intake more air?? must be high horse power !  can't recall ever seeing  such a set up

As Electric Vehicles are being pushed down our throats, I was wishing I was a wealthy car manufacturer..   I would build an E.V. with a Battery that is easy to replace, then I would try to encourage other E.V. makers to do the same, with the same style/ shape/ and wired,  battery, .. Then I would propose to have battery shops like gas stations.  You would pull in, get a battery change and leave your battery to be re-charged right there at the battery station.. no different then exchanging the bottle for your gas grill. I know that safe storage is an issue, but, they can be out doors in charging vaults, just in case one goes up in flames.  I know this will help E.V. owners go further in the car, as well as convenient.. 

 anyway, just some silly thinking by me...  Jojo

wouldn't call it silly thinking . signs of the future is more like it. question is ::will the vehicles hold all the computer stuff (back-up battery) while main battery swap. 

stopped at a Target store yesterday , they have huge section of parking lot tore up -putting in long line of charging poles.  seems that's called future progress. interesting to see another 20-30 yrs from now where all the expended batteries will be dumped = by then it may be discarded in outer space like trash from cruise ships dump in ocean.

guess it's a case of == gotta do what ya gotta do  !! LOL

Tailshaft out, going good so far. Will use a new uni.

 

guess that's why it is said --a picture is worth a thousand words, makes replies so much easier looking at pictures to understand  situation. thanks for pictures also looks as though you have your act together .  fact you asked advice  first also show intelligence. 

I've seen auto inflate system ; don't remember them looking like those. front line on steer must be a swivel joint on top .

the perfex B-81 has it's work cut out hauling the transformer. way in back large set of wheels must be a loader for pushing help.

also back wheels have same .noticed after I enlarged photo ;; why ??

also back wheels have same .noticed after I enlarged photo ;; why ??

excellent  photos; but I have to ask= the B-81 has guide poles on front steer axle which look to be part of a back up bell '??? purpose is ??

also once it has a body on it , driveshaft won't be as noticeable. 

you can always take some masking tape and spiral the driveshaft  ; paint it white like a barber shop pole. then ask the UPS driver his opinion. LOL  . I saw the B-42 at the Brooklyn show; you weren't around . You left when I was spending money at the flea market section. any ideas/hopes for the B-73 first show appearance??

it's same as cake Jojo; some are easy to cut ; some aren't. wait till you get on the old age side of the coin= you forget what you learned and haven't learned the new stuff being discussed. I'm going by top mount Mack -not front load.  off brand would be front mount in my day. it's called "built like a Mack " for a reason back then.

different in what way and why is it being replaced?

Harry,,  since I got away from Mobile Truck repair...after 13 years,,  my work days are not tough anymore.. Its just a nice little place to relax..    

with the help of a small excavator  , the brook that runs through the yard we rent now has a swimming hole . couple of trees cut down for sun light to heat the water. quite/ very private. even have a cut off branch that works as a clothes hanger for swimming trunks. LOL

since this is a "new"truck  2004 want to make sure I'm on same page. this rear comes out top as ole school or is it a front removal ?? reading comments of long guide studs which to me indicates front removal not top. do remember (sorta) taking rear tires off  to lower rear to ground  for carrier removal . seems it was a dump also.

have to consider it's the rear/rear in question; not a lot of room to work even with body all the way up. skid steer with fork extension be the way to go; situation is that would require at  least two people so operator stays in machine.

If you have a metal scrap yard near by a couple long pieces of 4 in channel iron might be cheaper then plywood to build a track for the floor crane. iron will also take the weight. it's a method that has worked for me. "portable " plywood floors have been used many times in the past; if load was light  or I was using as a creeper roll around floor. did take a quad out of a DM-600 using a car jack on plywood  ; NOT recommended.

now that confirms my suspicions ::: there are some " sick puppies" on here !!LMAO 🤣😂

Pretty interesting subject to discuss, thanks for lifting it up.

Honestly I don't remember hearing about those crytical speeds in the past but the effect sure makes sence. My guess older day's engeneers were familiar with that. Otherwise they wouldn't design shafts with intermediate carrier at all. Probably the road speeds were less in those days, especially for trucks.

Vlad

not only were road speeds less in those days = the roads weren't that well made to achieve high speeds. considering all mechanical items were basically an " over-kill" in design back then such as 55 K lb rears. all the heavy torque arms  and springs being replaced today with air bags , driveshafts possibly weren't a major factor. also other then west coast type units how many long wheel based trucks were there, if they were long . the shafts were made to suit.

go for it Jojo - I like competition in off topic=LMAO 😂 . interesting to watch and learn as members relate their vehicles  and exchange knowledge.

Prices have gone up over there to. A 1987 Superliner day cab, 12 spd was sold for $AUS86,000 plus buying fee maybe 5% online auction last Friday. Average condition.

prices didn't go up on only the real ones ; went to a local truck show today ,found some vendors selling scale model truck and misc. picked up a couple boxes i could use in the scratch-building projects. I heard the prices and replied " I 'm not asking to buy the real truck just theses models!!!  there were a few nice superliners  == real ones. gotta get back on topic. LOL

I bought a few items for the scratch built 60-70 ton beam trailer that were 3-D printed; on a PERSONAL OPINION ONLY I'm not impressed with 3-D. guess I'm tooo old = used to old school in all facet of mechanics whether real or 1/25 th scale. detail is excellent  3d . the make up of "stringers" challenges.

U can never have tooo much        (  o  )(  o  )

 

LOL

cya

they must be cold '' none of them have hats on !! at least they have gloves. LOL

is there enough tread left on the front drives to make it worth the effort to swap tires from front drive to rear drive ?  attempt to see if tires are problem  how are the rears wearing? pins/ bushings  etc should show problem with rear drives also. being a tri-axle any consideration to pressure on lift axle- tooo much taking weight off first axle/not enough front drive scuffing
