[MOD] Technic 40th anniversary model ... with diff

[kennywest]

So I decided to build the Technic 40th anniversary model, out of nostalgic reasons.

The problem is, as clearly stated in some of the reviews, there's a differential missing. As a result, the car doesn't steer nicely, so I decided to modify it and add a differential. Below are some pictures that show my modifications.

Not sure if anyone else already did this, if so, feel free to merge this topic.

It's actually not that difficult. Just disassemble part of the drive-train, use CV-joints instead of the universal joints.

The gearbox on top also needs some modifications, so you have to add the above 5L liftarm and move the tan gear more to the front.

I was planning on making an LDD file for this, so other people can build this.

Looks good! The Anniversary Chassis is one of my favorites for 2017.

I noticed that you had to use 9L beams in the rear, instead of the 7L beams in the model. I'not sure I can see where you used the 5L lift arms on top. Is the overall model longer now?

Looking forward to the LDD so I can see your solution, maybe I need to revisit the Chassis to put some of the mods You and @Seasider did.

The model is the same size. You can see the 5L liftarm I mentioned below:

The 20 teeth tan gear needs to be moved to the front, otherwise you will lockup the gearbox, due to there's another 20 teeth gear to power the differential.

Almost there :)

Do you really need a review of 'this'?

The model itself, no mods...

Oops, missed it.

I still need to stiffen the chassis on mine, too much flex at the joint (or lack of) between the Dash and Grey Nose and also the front of the engine to the gearbox.

 

It's currently sitting in front of me on my desk at work, I'll perhaps take it home one nice and plan the final mods. Once I'm happy I'll create an LDD ... possibly

Sorry to dig up this old topic, but I finally found some time to finish the LDD.

That’s spooky @kennywest I’ve just finished stiffening the chassis of mine and this week was going to make an LDD and post final pictures too.

@kennywest it is not that old topic.

Thanks for LDD

@Seasider curious to see your modifications. Please keep us updated.
