On those rear hubs (I mastered them) they are designed for American trucks. You’re using European wheels with a much larger center hole. Jamie has much, much better wheels and tires that would be much more accurate for your build.

Thank you my friends!

A question: if I have Moluminum tyres with 22.5mm Inside diameter, they will suit 22" discks?

Another question: Can I place an order through Moluminum.com?

You should be able to order right thru his site, I've done it several times with absolutely n issue. Jamie is a great guy to work with

Your working suspension looks fantastic cant wait to see more 

Before that, I must scratchbuild 4 front crossmembers specific for TopKick. 

By the way, does anyone have photos/schemes of cab mount brackets, front and rear, separated from the cab? I have some photos of cab mounts with the cab above. But I can' t see all of it. Specialy - rear one.

 Sergey,

       Very impressive work on this project !

As for ordering from Jamie . Number one he a a great guy to deal with.  But you like me live in a country foreign to the US. And on some websites this causes problems .

You might want to try to contact him through e-mail and work things out there ! TRhat is what I do and I live in the Philippines .

 

  Be Well

Nice work Sergey! Your scratch building work is very impressive. About the wheels, it appears you are using  European style rear wheels, they have a larger center hole and larger lug pattern than American trucks.

I just have bought Jamie's wheels. The only probleme I can't upload new photos.

I can't see anything under hidro tank & cilinder. Does anyone know: is there a transfer case on TopKick to tilt the dump bed?

Strange! When I try to upload new photos, there is 404 Error appear. Am I the only one with this probleme?


 

Sometimes i have this too, than i have to start all over again with the topic.

These days i copy the whole txt with image link, paste this to aword document, than refresh the MCM page and copy past everything back in the Reply section.

I don't know why it happens, but this works the best for me....in case if it happen again.

A little update with the wheels.

I have bought couple wheel sets at Jamie

38_online

This is trailer set, but I will use them for rear bogie.
Jamie's Rear tyres, I bought several years befor at Sourcraut, turn out 1mm wider than discs. Modern Jamie's tyres are narrower.

39_online

And there is no gap between rear wheels. Iguess I should make 1mm spacer from styrene.

40_online

Slightly increased the center hole on the front Italery's disc

41_online

Yeah, the second set of wheels had a couple extra front hubs.

42_online

...BUT somehow, let's call it the mating plane (marked with arrow) is very narrow and the width of the brake drum - the same

37_online

And if the second thing was treated with cut down spacers of 1mm polystyrene, then the first needed a piece of tube with 12-14mm diametr. I had to cut a piece out of a 16mm tube.

43_online

Here is how it looks like.
