WooHoo!

[egronvold]

Looking good, Bo!

[frizzen]

That's a really sharp Merc outfit. Was it an old tamiya body, or Freddy custom?

Are the trailer tires supposed to have that much offset? Looks good either way.

[Bo Wallen]

Thanks, Frizzen. Yes, Freddy cut that body and made it to a day cab, model short. The Trailer has the longer axles, 140mm. I think duals have 120mm if I remember right. After the Merc, I will rebuild the Trailer to extendable, the trombone type and more axles, of course.

[Bo Wallen]

Some other stuff arrived. Let's do this.

The steering mod. Is all done, The extreme short wheelbase makes this truck to turn sharp, very sharp.

[IMG]IMG_6248 by Bo Wallen, on Flickr[/IMG]

I also need to fit the Heavy Haul Push/pull couplings front and rear, and Plates has to relocate.

[IMG]IMG_6255 by Bo Wallen, on Flickr[/IMG]

Air tanks and "battery" box also in the works to be installed.

[IMG]IMG_6252 by Bo Wallen, on Flickr[/IMG]

More to follow.

If you are looking for cheap tamiya based driven steer axle conversion kits then watch my store

[Bo Wallen]

Thanks, Nick. Yes, a slight extension to the fleet, Your front axles will be needed for two of the Benz. The Lesus is just garbage

I guess you dont have issues with the stock Tamiya rear axles?
Here is a sneak preview for you

[Bo Wallen]

Thank You, Nick. I have a good feeling about your project. I will Have your product Incorporated in my fleet. The original Tamiya axles are right, and if they get tuned tight when built, they will last a long time. I have axles with far more than three hundred hours on them, still running smooth. So let's have the two current Mercedes on the bench run your front axles.
I am looking forward to working with you. Nick.

I currently have 1 pinion out of 6 which jumps out of mesh, it's a different design to the other 5 on the 8x8 so not sure where it's from but will add a circlip or washer between the gear and bearing then full testing can commence!

[Bo Wallen]

The Mesh is extremely important on casted gears; There is no shortcut at that.
However, Tamiya does not make metal parts in the house. Therefore the gearbox has two different pressure angles on the gears, Old standard and new. Witch makes the gear to go down faster than it would with the same pressure angles. Now Japan is a monoculture, so the boss does not know that, and a new gearbox or axles will not be on the horizon for some time. But the work so I stick with them.

Yea its very odd all the axles ive built so far have been spot on besides that one pinion that has free play but ill get it sorted!

[Bo Wallen]

Just came across this site again. Over Milion's views. https://www.youtube.com/watch?v=NNVn8fLy5Ro

[Bo Wallen]

Today I started designing the solution for the weakest part in the gearbox, Hope it will work as good as I hope.

Design and Machining, my self. Hardening outsourced.
