Subject: Kenworth w900L / W900B


have a '98 Kenworth that is clearly a W900L but the door tag says W900B

hood has definitely not been replaced
truck is original and is no different than a newer "L" model in terms of configuration
was this the norm on late 90's model w9's ?
did they still call the base model a W900B and badge them as W900B's but just designate them as "L"ong hoods when ordering? like peterbilt with the exhd

Have newer ones that say W900L and an old true W900B that says W900B

that's why im curious!!

anyone else have one like this? if so anyone know how long they were like this?
any information would be GREATLY appreciated as i am getting ready to sell this truck
had a guy come look at it today and looked at the door and noticed what I never had before (that is says W900B instead of W900L on the door tag)


after spotting this, he was then CONVINCED in his own head that it is a w900b that i put an "L" model hood on,
but that's NOT the case, nor is it possible without modification/reconfigure cab-engine move back chop job

he ended up making me mad because he started telling me I didn't know what i was talking about
(to be completely honest, the part that made me mad was I didn't know what i was talking about, hahaha)

**I do know the very very first "L" models back around '89/'90 were not actually called W900L's, but in fact W900B Extended Hoods and that you ordered them with the 130bbc extended hood instead of the standard 120"bbc W900B hood, but assumed that this was something they did away with as soon as they came out with the W900L designation.

am i wrong in that regard?? I'm thinking now i may be, but if i am, was it like this on all the W9 trucks of the same vintage?

once again, ANY information would be greatly appreciated!!
it seems like it has already cost me selling a good truck to a ready buyer because he was worried it was cobble-together jobby or a re-builder, i just want to know what Im talking about if the next ol' boy has the same question

THANKS!!

I have a 99 model and now that you mention it, I kind of think it might be stamped B when it is surely an L. I will check in the morning and let you know. Nice looking truck.

I wouldn't lose any sleep over that guy. IMHO he knows less about KW's than you do. Anyone who knows KW's can tell a 900L a mile away no matter what the tag says. For him to say you changed the hood is further proof of his lack of knowledge. We have/had (5) 900L's and not a single one says 900L on the tag. What 4 out 5 of them DO say is Constructor W900. A call to any KW dealer with the VIN would be proof that it is 900L. However, I cannot answer your question, have always wondered the same thing you are.

There are a lot of trucks that are stamped W900B and are W900L's. I remember hearing they are all stamped that way, but I do not know if that was true or not. i could call KW now, but I'll probably call tomorrow so I can ask our salesman just out of my own curiosity .

you usually see them anywhere from $35,000 to $15,000 depending (about like case ih 71-72 series magnum tractors, you see them advertized anywhere from $15,000-$80,000,haha)

i was going to daycab it and shorten it up for farm use, but truck really is in too good of shape for me to go hacking on :-S

Just called to confirm it. W900B just means its the later generation cab. Kind of like they did with the T600s and T800s, the later generations (even though the cabs didn't change much) were T600B's or T800B's (Unless they were T800H,T800W,T800SH).  Thus all W900s since the late 80s are stamped W900B's.

Made sense to me and it was what I had suspected but wanted to confirm.

See below for a lot of the info. 12.7 Detroit, 10 Speed "C" ratio, 3.70 Rears. Judging by the pictures, 24.5LPs, can't tell if it has AG200 or AG100 from the picture.  The trans is rated for 1500ft-lbs, that would give you an idea where the motor should be rated.

Subject: Re: Kenworth w900L / W900B


thanks again durallymax!
ya, that makes perfect sense to me as well,

nobody that works for any of our local Kenworth dealerships really know much about model history, or to be honest history or model info in general (they sell or work on trucks, and can pull up info about the truck if you have the last seven of the vin, but in terms of knowing much more than that, notta)

please correct any of this that may be wrong as I am just stating what i currently THINK is correct, yet any or all of it could be completely wrong
you may know what i dont and I would love your input for future reference

*T600B is same as T600 but with the newer hood "distinguishable" with the fiberglass and center bar instead of the flat chrome front with traditional bar

*T800B is pretty much the same as original T800 but with updated interior refinement

*T800H is a T800 (set back front axle) with a W900 style "High" (hence the "H") hood (otherwise known as "Michigan Specials"most of these were sold to Michigan or there abouts to pull Michigan trains or to coal country and seemingly used the higher hood to make room for a larger radiator but were distinguished from W900's because they had the T800 set back axle)

*T800W is a T800 with a "Wide"(hence the "W") hood. They have a much wider grill and the single square headlights and where sold mostly for heavy haul and big payload configurations (also seemingly having a wider hood and grill to make room for a larger radiator but without looking as goofy or affecting visibility like the T800H)

*W900S is a set forward front axle (hence the W900) but with a "Slant" or "Sloped" ("S") hood. They are seeming what could be called the same thing as a T800 set-forward front axle but thats not how kenworth chose to distinguish them (they stuck to W900 meaning set forward axle, and T800 meaning set back axle even if engine placement and all other configurations are similar) and these W900S trucks are almost always sold to fit straight truck applications where a maximum bridge length is required, like cement mixers or super dumps, but a slanted front hood with better visibility is preferred, and almost all of them roll out of the factory with 18k+ front axles and wide base 385/425 floats)

*I don't know what a T800SH is,
is it a high hood as well??

Thanks Again!

yes, durallymax is as usual 100% correct
the truck was built in 2/98 and motor was built in 1/98
it is a 470hp 12.7L Detroit series 60 wit a DDEC IV computer ( full engine rebuild about 270k ago by Detroit ("certified EPA LowNoX rebuild" and computer replaced in 2011)

straight 10 tranny with 3.70 rears just like the door tag says
It is the original AG100 (Air Glide 100) rear suspension with updated bushing package and the newer style cast aluminum center support brackets (elephant ears)

24.5 low pros all the way around
matching date code alcoa rear aluminum outers with steal inners (thats the way she left the factory)
rear tires are all matching virgin Kelly drives at 20-25%

front tires are like new Michelin XZE's on brand newAlcoa 24.5 durabrights (I still have the original matching date code non-durabright fronts if they would be preferred over the Dura-brights)

truck is very straight and clean for a '98
amazingly original other than updates (seats are even the original other than lower cushion of driver seat being recovered)
original CAYMEN GREEN paint
front bumper is original

pulls and drives VERY WELL for a 15 old truck
no shimmy's or rattles at idle either :-)

Yes that's basically all correct.  The later T600's had a fewer other differences as well, but the grille is the obvious one. 

 

The T800W can fit the largest radiator of any of them.

 

The W900S stayed a W900 due to the axle placement, many get a little confused by it. 

 

The T800SH is the short hood model, very short and not rated for big power/big payload applications.

As for the naming, the Kenworth name came from Fredrick Kent and Edgar Worthington. They combined their names. This is also where the "K" and "W" come from in model names. K representing cabovers and W respresenting traditional long hoods.  I cant remember his name and cannot find the history article I read, but the "T" came from a later influential preson in the company. I am not sure if "C" came from the same or not but would guess it did.


To put it into picture perspective I found some pictures. At the end I attached a spec sheet as well for some of the trucks. 

T600A





T600B, earlier ones did not have replaceable fenders or turn signals at the back of the hood, a couple years had the rear signals and then in 97 they went to replaceable fenders.

 


The T600 was replaced by the T660 to accomodate the new emissions engines in 2007.  These are very distinguish able. Some people put mesh grilles in their T600s and can confuse some people who are not familiar enough with the KWs.

 


Next came the T680 last year. This DID NOT replace the T660, it was a model that bridged the gap between the T700 and T660.  Its currently the most fuel efficient truck. 

 




Below is a picture of a standard T800. You will notice many may look a little different. The Flat panel windsheilds have a more curved hood where the Aerocabs are more straight.  There is also a split fender model as well, but it is a shorter hood IIRC>




Then there is the T800SH or Short Hood





The T800H or high hood.





Then the T800W, other than its bold grille, the headlights are the obvious identifier on them . Not all T800Ws or T800H trucks have larger tires on the front.





Last month KW introduced the T880 which keeps with the theme of the T800 but utilizes the new cab that is used on the T680.





Then there is the W900. The first ones are coined the W900A by many even though that name came later after the B's were introduced. The W900A can be confused with the later W923 and W925s sometimes. The W900A also came in an extended hood version if your ordered the big motor (12v71 Detroit, KTA1150 Cummins, 3408 Cat).  First pic is short hood, second is long








The W900B was introduced in the 80s, the early ones were different from the later ones somewhat.  One thing that adds a lot of confusion especially to the W900 models is the Aerocab.  The hoods for the Aerocab are different from the hoods for the Flat windsheild.  With people being used to seeing aerocab trucks now, they see a W900B and see the hood is mostly flat and the W900L is sloped and curved. Then you see a non aerocab W900L and many people think its a W900B.  It can get confusing. Just look for the added spaced panel behind the fender and you will know.  The Fenders are different on the B and the L as is the grille.

W900B Non-Aerocab

 

W900B Aerocab

 

W900L Non-Aerocab





W900L Aerocab






And then of course there is the W900S








Hope that clears some of it up. Of course there is also the various C500 models which some people confused with T800s at times, the K cabover models, various other older models, the medium duty line, overseas models and the mother of all 963 shown in one of its various configurations in this picture.

 



 Here is a link to a brochure that shows a lot of the specs and configs of the heavier trucks.

Subject: Fuller 10 Speed Trans


when i said straight 10, i just meant it's a 10 speed that shifts like any old road ranger 9 or 10, and not a ""Super 10""
i didnt mean that its a straight 10 as in straight "non-overdrive"
to clarify, it does have an overdrive and a "C" range gear ratio set
that what the "O" after FR stands for in "FRO15210C"
with 3.70 rears, overdrive, low pro 24.5's, and a 12.7 ddec four you wont find an extended hood truck that gets as good of fuel mileage :-)

as of now its sold but ill keep you posted

An L model Kenworth with a B model cab only means the interior is a little different and the windshield is flat "flat glass"....... If you were to order an L model cab you would get the curved more "aero" glass and interior was slightly altered.

B model cab is just the latest design that they have used since the 80s.  You could specify non-aero cab or aerocab for either short hood or long hood models.
