I'm responding to question #1, the W900A never was, it was the replacement to the W925. there was two types of these W900's the extended hood for the larger engines like the 3408 Cat, and the KT Cummins, V12 Detroits etc., and then the short hood for regular engines like the 3406, NTC's, and 318's. Somewhere around 1983 they did away with this series and rolled out the B model, at this point people started referring to the original W900 as an A model. The B didn't prove out too well with alot of O/O, and alot of them went with the Peterbilt 359 where the long hood was still optional. Kenworth came out with the 007 model which was a B model cab with a long hood, they were so popular and with the sales lost to Peterbilt they decided to re-introduce a long hood and it was dubbed the L. On any of the ant eater styles you'll have to ask someone else, I don't consider any of those Hoods just engine covers.

 

Here's even a more confusing thing....
The W900L is assembled as a W900B and as such, on the door and build stickers
it claims it is only a W900B..but really a W900L.

My W900L hood is a full 72" from the edge of the windshield to the hood emblem
and the W900L have an extra piece from the base of the hood to the forward section of the battery/tool
step boxes. (spacer panel)

I have the updated AG400 suspension. The truck did NOT come from the factory with it.
The newer style requires almost no maintenance for light, except for the $120ea air bags...

There is a thread on this site somewhere that offers all of the information such as length for all of the models, and how to tell them apart...

 

In responce to question #9 the 3406A was Cats replacement for the 1693, the A was a precombustion engine with pre-heaters and its horsepower topped out at 385 if I remember right. The B model replaced the A, this engine was a direct injection engine. The early B's ranged in HP from I think 315 or 350, up to 400, the later B's had air to air added along with timing and fuel pump changes to boost it to 425 HP. The B was replaced by the C and was pretty much the same engine, with the greatest differance being a wider rod bearing. The Peek engine was basicly a C model with the first attempt at an electronic engine but never gave the service the mechanicals gave. The E was Cats first succesful attempt at building a dependable electronic engine, which was still a 3406 with alot of changes, and from there we get into the C-15s and from there you might want to talk to Mr. Haney.

 

the b models are defined by the square headlights the older w900's with round headlights are "A" models.......nothing to do with what engine it has .......they are expensive because they are paccar products .....i always had freightliners because i was in business to make money and shaker parts are at least 40% cheaper and the truck makes as much as any other ....

 

It can be confusing for us guys on the front lines as well!!

 

My dealer is usually clueless. If I try and order a KW part but it wasn't on my VIN - they look at me as if they dont know what to do .

It not rocket science here.
I needed some trim panels from a different rig.
I took his panels off. Took photos of the panels along with the part sticker (showing the color codes and what not) and my idiot dealer still didnt know how or what to order.

It is very hard to find ANYONE competent now.
