Scania T142

[PierreR89]

Started work on the Scania T143 "roadrunner" that i bought from ebay a few weeks ago.
The frame and engine are done now, just have to paint them.
I also have to find the right Scania green that they used on the engines for the 3 series trucks, the instructions say black/grey but that is what is used for the 4series that also have a new engine.
Sorry about the blurry photos i dont know why my phone did that...
Frame:
It is not the wheels that is going to be on it when it is done

Compared to the AMT Kenworth W925:

Rear suspension:
Those who drove Scanias with that suspension used to joke about them and call them for "flintstone suspension" because it did not work that good...
They had about as much suspension as Fred Flintstone's car have...
As a result of that the towers that hold the axle to the frame used to crack and in the worst case the axle could simply fall out from under the truck..
When i worked as a mechanic i had to drive out to one Scania with this setup and use straps to secure the axle to the truck again because those towers had broke in half so the truck could not move.
When the driver drove forward the axle just dragged behind it, reverisng ended up with the drivewheels wanting to climb over the axle so the truck was stuck there untill we could get the axle tied up the the frame with straps...


14Liter Scania v8:


Just for fun i compared the Scania v8 to the CAT3408:
The CAT v8 looks small compared to it

Engine testfitted in the frame:

Also just for fun:
The CAT engine was to short and not wide enough so it almost fell through the frame..

Nice start.
The Cat engine is 1:25th scale and the Scania DS14 is 1:24th scale, that's why they are different in size, the Italeri kit can also be slightly over scaled and the Revell kit under scaled and the differences gets larger if that's the case.

Another thing tho'
Italeri has one thing wrong in the instructions for the Scania and they have allways had that fault from the very beginning, the instructions show the part (lift beam) at the white arrow on the picture below upside down as you have mounted it, if the lift beam is mounted that way the support axle lift will not work.
The lift beam should be the other way around and the hook parts on the lift beam should be above and push down at the rear spring mounts forcing the drive axle down and the support axle goes up.
When both axles are down the lift beam should be up against the frame rails away from the suspension travel with the hook parts pointing upwards.

 

Here is a picture with the lift beam the correct way so you can see how it works when the support axle is lifted.

Thanks, i had a feeling something was wrong when i mounted it because it did not look like they did on the trucks i used to work on.
Did you do anything else to the rear supension to be able to have the axle lifted?
I also have to fix the wheelhubs on that axle because those that is in the kit are for a driveaxle and not a tagaxle.
The hydraulic piston used for lifting and lowering is also wrong compared to T142 i once worked on, that was round and not square.
The only Scania i have seen that had a square piston was an old 110 super.

I have been around trucks and Scanias my whole life so I noticed immediately that the lift bar was the wrong way in the instructions when I built my first Scania from Italeri back in the 80's.
The bogie on the second picture is not mine, I found it on internet somwhere, I just used it to illustrate this, but to be able to lift the axle you have to cut and do pivot points where they are articulated on a real bogie, some work but it can be done.
As for the drive and tag hubs, the Italeri ones are far from right but KFS has some nice more correct looking hubs available, they have just released several new hubs from 3D printed masters on their website.

Almost done with painting the frame and engine, just some small details still to do on them.
I also have to mount the fuelfilters on the engine as i realized that i forgot to put them on it...
The engine is almost the right color its just a bit to dark.
The silver on the scania logo's is the best i could get it because they are so small and my hands are a bit to shakey after an old workdamage i have.
(For those younger folks/or older here that are using pneumatic tools daily, make sure you use good thick gloves if the tool vibrates alot... i didnt and now i am paying for that...)
I am thinking of painting the taillight brackets and brakecylinders black.



I have also changed the liftbeam so now it is correct and not upside down.

[PierreR89]

Painted the bodypanels and hood in a metalic green color.
It is a bit more darker then what the pic's show.
I think it will look good with the silver frame and the green cab when everything is done on it.

[gatorincebu]

I like what you are doing on this one !

 

 

be Well

Thanks, i decided to do it this way because the decals was destroyed for it, there are maybe 2-3 that are usable the rest is cracked.
Did the last on the engine today, now i only have to make the exhaust look used but that is easy so it can wait untill it is time to mount it in the frame for the last time.
Also tried painting the airtanks in another color then black or grey so we will have to wait and see how that turns out, it might work or not.
Also painted the brakecylinders black.
Painted the oilcap red as it was on the Scanias i worked on, added the fuelfilter holder inside the V next to the injectorpump and painted the silicone hoses on the airintake orange.
What are you using to replicate injectorlines on 1/24 engines?
I am thinking of adding them to this one because those are almost the first thing you see when tilting the cab or open the hood on the 2 and 3 series Scanias.

 

[PierreR89]

Assembled the main parts of the cab and testmounted it to the frame.

[PierreR89]

As it sits right now.
Engine, radiator, batterybox and airtanks in place.
Because i know Scania used red coolant for their trucks i painted the bottom of the coolanttank red, unfortunatley it turned out to red compared to the real coolant..
The real coolant is a mix of red/purple/pink, really weird color.

The tank that is halfway painted blue is the alcohol container for the airdryer system ( 2series used alcohol to dry the air from the compressor, 3series started with spin on airdryer filters)
On the real trucks the batterys for it are on the left under the batterybox cover and to the right is the airdrying system that the tank feeds.
I painted it blue just because that was the color of the alcohol we used at work to top off the system when we serviced them.
I have to clean it up a little more.
On the real trucks if a regulator failed in the airdrying system it would allow the compressor to charge as much as it could and send the air stright in to the plastic tank that holds the alcohol where 2 things could happen.
1 the cap just flew off, #2 the whole tank exploded...
Finding a new one of those tanks was not easy when we had to replace one at my old job..

I have also changed the liftbeam so now it is correct and not upside down.

 

Yes that looks right.

You have done nice progress so far.

[PierreR89]

Its starting to look like a Scania now.
Now its almost just the small details left, grabhandles,mirrors, lights and that stuff.
Have not decided if i am going to use the winddeflector and cab fairings that comes with it
I also must think of a way to make the front bumper and bullbar removable or so they go with the hood when opening it.
Italeri wants you to glue the front bumper to the framerails and then glue the bullbar to it making them permanently attached there and the hood not being able to open.

[PierreR89]

Just added a few details to it since the last time.
Still have the sidemarker lights on the front and above the doors to mount, airhorns on the roof, exhauststack and maybee the winddeflector and fairings if i can make them fit...
Have to clean up the rear lights a bit more, they looked good on the partstree but did not turn out that good on the truck.
Before anyone asks, no the gap between the black lighthousing and front fender should not be there. There are alot of fitment issues in this kit..
Compared to the revell's "50 years of revell" showtruck kit that have basically the same truck only theirs are a 143 and this 142 from Italeri, the revell kit fits much better but that is probably because it is a few years newer.

I think i came up with a solution for the destroyed decals with this kit, I bought a set of decals for the Scania silver griffin and black amber from ebay.
Some of those decals might fit somewhere on this truck.



 

[PierreR89]

Did some small things to it during this week.
Added the airhorns, exhauststack, sidemarkerlights on the front and on the cab and put some decals on it.
Decided not to use the winddeflector, fairings and bullbar bumper, used the stock bumper that was in the kit instead.
Here is how it looks now:






I am also trying to figure out what trailer it should have hooked up to it. I have not decided if its going to be the timber trailer or schmitz dumper trailer that both revell and italeri have.
Also going to buy new wheels and tires for it and new hubs for the tag axle so it looks like they do on the real trucks.
 

Edited September 15, 2017 by PierreR89

[PierreR89]

Ordered som parts for it earlier.
Decided to have super singles on the front axle, got new drive and tag/liftaxle hubs, new wheels and tires with drivepattern for both rear axles.
Also decided what trailer it should have and i choose the triaxle gravel trailer from MPC as it looks like the old gravel/dump trailers did when this truck was used.

Untill anything of that arrives it's not much more i can do to it.

[gatorincebu]

Your project is looking good. However I am curious about the new part you've ordered.

 

 

 Be Well

[PierreR89]

Here are the correct hubs for the rear axles, the 2 to the left is for the liftaxle, the 2 to the right is for the driveaxle

Here are the supersingel front tires for Scania from Italeri:

Testfitted the trailer to see if i had to move the fithwheel or not but it could stay where it is mounted on the truck.
It will look something like this when everything is done:
The Scania is completed now after i mounted those parts to it.
