80ish Autocar DK-64 HH tractor.

[ShakyCraftsman]

Hello Everybody 

Okay, before everyone goes crazy. I didn't want to start this build right now. I received the AMT Autocar DC-9964B dump truck kit from Amazon. 

  I was originally going to build Stallone's truck from "Over the Top".  While doing research for it I came across "Diesel Creeks" videos on his (Matt) 1980 DK-64 Constructor and after watching the videos I decided to make a kinda version of Matt's truck.

 I actually just went to the bench to trial fit some tires to the Autocar's rims to see if they fit. They are the 22.5 RoadX TD990 from Paul at ST Supply. I wanted to see if they would fit the rims and voila! They fit.

As you can see they fit good and tight.

View looking at the tread.

View looking at the back. Like I said they fit good. But I think they are to tall and aggressive for the truck I want to build.

 So, as I was trying the tire fit, I started to look for tires that would work. And digging through my stash I found some that I think will work just fine. This turned into more investigation into my version of Matt's truck.

Hey all 

 So, just as Matt's going to do,  I'm replacing the small cam Cummins NHC-250 with a Revell Cummins NTC-475 TT. Although Matt is using a big cam 400 (both 855's).

This view shows the kit 250 on the left and the 475 on the right.

Something other side.

This view shows the air compressor/fuel pump on the left and the oil cooler on the right.

This view shows that I filled in the back of these pieces to make them look more realistic.

This view shows the oil cooler after I made it into a twin filter version.

Back side of the oil cooler.

This view shows the oil cooler mounted to the engine. It also shows the pipe I added to the front of the engine.

Hey all

 More work done on the Autocar.

This is a picture of Matt's truck.

This view shows the 475 assembled and the pipe I added to the oil pan and the front of the engine.

This view shows the other side of the 475 with the twin turbos.

This view shows the engine with some pre detail paint added. Well that's it for now be back with more soon.

This Looks Great!

I'll be watching. The changes you have made to the engine are very sharp Scratch Building.

[Gary Chastain]

Oh I like where this is going. You adding the intercooler for the turbos on this build?

I have wanted to do a twin turbo, but a little unsure how to go about it, so I will be watching closely to steal some ideas😜🤩🤪

Hey Gary 

 The only twin turbo engines I know of are the Revell Cummins NTC-475 TT and Jeremy's resin Cat C-15 Acert. There not to hard to build, at least the Revell one isn't, hardest part is keeping everything lined up while the glue dries. The Cat is alot trickier, there are NO instructions to go by. I have some pictures I got from Jeremy for the C-15 to show how to go about assembling it. If you want I can PM them to you.

Jamie at Moluminum has a resin C15 twin turbo, if that's what you mean.

Yes, but he is in the hospital and his site is down and may not come back. You can also get a C-15 from Paul at ST Supply.

Hey all 

Not really an update just pictures of the NTC-475 and the kits NHC-250 that I turned into a NTC-290.

This view shows the Revell Cummins NTC-475 on top and the kits NHC-250 that I made into a NTC-290 I still.need to make a connecting pipe from the turbo to the intercooler.

This view shows the other side of the engines.

Ohh I knew he had taken a brake for some reason but I did not know it was so bad.

[ShakyCraftsman]

Hey everyone 

I did some more work on the NTC-290 Cummins. Added details to it. Also just for your information the Revell NTC-475 Cummins does NOT come with a starter moter! You need to steel one from another kit or scratch build one.

 I'm actually thinking I'm gonna use the NTC-290 instead of the NTC-475 in the Autocar.

This view shows the turbos that I moved down to the correct position. Also you can see the Tichy train bolts I added to the turbos. The little brown things.

This view shows that I moved the starter to the left side of the engine.

This view shows the Tichy bolts I added to the intercooler top plates. You can also see the turbo bolts.

This view shows the intake tube on top of the intercooler I scratch built for the turbo.

Another view of the turbo intake pipe and turbos.

This view shows that you don't get a starter with the Revell NTC-475 Cummins.

This view shows the starter I scratch built for another Revell NTC-475 Cummins. Well that's it for now be back soon.

You know that I will be following this one. Diesel Creek is what got me interested in expanding into the big rig world so I could do a very similar build to yours.

Hey all

 I got a little done on this build today. Got the frame assembled.

This view shows the frame assembled.

These are going to be the final front float tires and wheels. Kit wheels with Italeri 385/65 R22.5's.

Front tires.

These are going to be the final rear tires and wheels. Kit rims with Italeri 315/70 R 22.5's.

End view of the rear tires. Okay that's it for now be back soon.

Oh…liking where this is going, watching

[ShakyCraftsman]

Hey all

  After conversing with my buddy (Jeff) I decided to change to a more aggressive drive tire that actually fits the rims better. They are unbranded Michelin XZL's.

This view shows the fronts and rears.

This is kinda of a look down on the truck view.

Hey everyone 

  Got some more work done on this Autocar DK-64B tractor. The rolling chassis is about 80% done. I have the frame and suspension finished all I have to do is add the battery box, fuel tanks, etc.

I added bolt heads to the bell housing. I still need to make a top cover with bolt heads and shifter tower.

Another view of the bell housing bolt heads.

I added bolt heads to the rear axle housings.

I also added some more bolt heads to the rest of the rear ends. 

I also added the two thin pieces on each side to the axle housing that trap the rear springs. These were missing from the kit.

This view shows the rear ends together with the rear springs and drive shaft.

Drivers side air tank installed.

This view shows the air tank fittings. This is how I'm going to plumb the tanks.

Another view of the right and left air tanks.

I added some Tichy bolts to the front springs.

Another view of the front springs.

This view shows the fifth wheel set up I'm going to use for this build.

This view shows the peices to the fifth wheel.

I bought this for my Mack build. It says it's a dropped axle but it was a regular straight axle. So I'm going to use it for this build.

View looking down on the front axle.

This view shows the front axle turned to the left.

This view shows the front axle in place on the front springs and frame.

This view shows the rolling chassis temporarily together.

This is a little mock-up of what the finished truck will look like. Well that's it for today be back soon with more.

Lookin good Ron!

[Biggu]

The mock up is great. She will look a real tough old school heavy hauler. Just like they should be.  Like this one

[Gary Chastain]

Ron, I just read back thru your post, are those rear axles from the kit, or are you using different rear axles?
