I wanted to know if someone can help me place the 2 items A and B properly on the tractor. I figure A is a step maybe to be placed behind the fuel tank but not sure with the funky shape it is and B I don't know. I thought maybe B is the door handle but seems like it's way off if that's what it should be.

I think it's funny how A-Line make such nice rims, tires, and fuel tanks but on the model you buy from them it's not the nice ones they sell. I had to add the rims and tires and I'm not sure how I can replace the fuel tanks without a lot of work to get the steps on the side like the ones that did come with this model.

I had a problem with a air horn getting away (dropped it last night @ 3am and never found it) so I replaced it with one I had in the scrap box but I figure they will be coming off when I get the airdam added. I need to get my hands on some roadway decals as well. Then some weathering and a trailer and it's ready for the road. What would be the correct trailer for this cab?

Thanks for any help guys.

The tractor is a Herpa/Promotex, with A-line wheels, thus the lack of fine detail elsewhere. "B" is the Mack bulldog for hood.

Off hand I cannot remember where "A" goes.
 
I could tell the tractor is Herpa because the mud flap has there logo on it and the rims (wheels) are just like the other Herpa models I have. On this one I replaced the rimes and tires.
I thought that B may be used for the bulldog but prototype of the tractor has a handle on the top center and not a bulldog.
Thanks Josh,
Dave
 


B is in fact the Mack Bulldog that goes front and center on the hood... There should be a small hole for the bottom of the Bulldog to rest, and the smallest drop of glue should hold it permanently in place

B is a step that is "supposed" to go behind one side of the fuel tanks. I end up leaving them off of 99% of my Promotex cabs because I can never get them to properly fit and look right... Plano Models makes a good replacement step that is etched brass and WAY more detailed then the supplied step you get with the truck....
 
I've only used A on my sleeper cabs as there is no real place to mount them on a day cab

That actually makes sense, I just compared 2 Promotex Mack Cabs, one a Mack CH 613 and the other a Mack CH 603 Day Cab. The Day Cab does NOT have a spot for the step because there is not enough room between the fuel tanks and the first drive axle, but the CH 613 does have room because of the extended chassis. The CH 613 also has a frame crossover plate, and the step fits right into place on the both sides of the cab to line up with the crossover.... I dont know why I never noticed that before :o

I dont understand why all the Mack Cabs, regardless of them being sleepers or day cabs, come with the steps though? It makes it confusing for someone who has no idea what the heck they go to and where LOL I think some simple instructions would be benificial to someone who has never applied the supplied details before... Good thing ive saved every single step that I have put aside when I could not figure out where they go instead of just tossing them. I think ive got about 60 steps sitting here in this little cup LOL

The only thing I don't like about the frame step is you have the chrome bar sticking up from the step. I guess that's where you would hang the lines runnning back to the trailer. For the bulldog, I wish they added the handle for the noise and not the dog. Well, I'll see how I move forward with this one. I'll post photos when I'm done building it. Any leads on really good Roadway decals?

you got your answers but would like to add a little.

A is a step that is often used on trucks with longer frames to aid in getting up on the deck plate to hook up air lines and such not common on short city trucks as there is no room for them.

B is the bulldog. Roadway used a handel on some of the CH model macks just like ups did with the CH macks. However mack started to include them for no extra charge even when companies ordered them with every cost cutting ways they could think of. I have seen old Roadway macks ordered without RPM or fuel gauges. Had to use a stick to check your fuel level!

Josh,

Its cheaper for the factory in China to make a bunch of the same sprue with extra parts on it for different models, than to have separate molds that always need to be swapped-out. I've seen this many times in my Walthers Cornerstone building kits, I just save the leftover parts in my scrap box. I definitely agree with you on the need for better instructions though...
 
Josh,
As Ken said its just a part off a tree that some models can use and others may not. so they throw it in with the package and you can use all the parts or just the ones for the specific model. If you ever built a 1/25 scale truck model you often will have spare parts left over as you have diffrent options such as square or round fuel tanks. If you ever have questions about truck parts feel free to ask me as iv been around them all my life.
 
The A-LINE wheel upgrades really make the cab stand out and look so much better! I just bought a hole bunch of them to start replacing all my cabs with new wheels lol
 
They do improve the cab a lot like make it look like a toy turned into a model. I need to get a ton for myself. I need like enough to do 30+ trailers. I just got a boat load of roadrailers and a lot of regular trailers.

Dave
 
The budd disk (2-hole) wheels are great! Especially if you can manage to get a toothpick with black paint (which I have done) in there for the 2 big holes...
 
Thanks for the info. I have some lights from Lonestar I was going to add and the rims are going to get a coat of paint as well. I'm thinking I need to add the air lines to the back of the cab and maybe a metal plat over the frame there as well. I think you are right about the wipers needing to be black as I don't think I'm going to use the a-line wipers I have on this model.

I'll be sure to post a photo when it's done
