Dlux Berg Build

[Erik D_lux]

Stock was aluminum? The ones I have here are used so who knows what I got but they are steel and look just like stock Berg, steel too.

You must have got berg ones. See the below link. You can see that they are Alum

Huh.

Where did the locker fail?

 

[TSK]

Hmmmm... I'm thinking maybe I could buy 1 set of the HR gears, and just replace the large 2nd gear in both my axles. Then I have standard 48p gear for my 9t pinions to mesh with, and the small 2nd gear and the rest can remain the OG berg Mod .6 ppitch:idea:

Then again I could be totall wrong.

 

[Erik D_lux]

Thats good thinking to me!

I think this might be an option worth looking at on my super too. I have wanted smaller pinions but heard all the .6 gears lower than 12t are not so great.

 

[Chris_The_Battery_Man]

They failed at the face of the locker. The shaft would twist in place, and spun the flat to a circle. Wish I had pics. Perhaps I do. I will have to look through my pics later. But I really think it was due to the depth that the axle sat in the locker. Pretty sure it was only a few mm. So naturally it would push out some, then spin in the locker.

You cant inner-change the gears. At least I don't think you can. Last I remember trying you have to keep the sets together, because they dont mesh together. The main "spur" gear wouldnt work for some reason.... I think it was too large in diameter, and hit the 3rd gear shaft. But I am not 100% on that.

One way to find out!

So you better try it and let me know how it goes:mrgreen:

 

[Erik D_lux]

Ok, so it looks like you could do just the large 2nd gear if you wanted to put some work into it.

The large HR 2nd will hit the sleeve on the large Berg 3rd. You could simply cut that sleeve off and then you could turn down the small Berg 3rd so that it fits the smaller bearing and then leave a shoulder on the small Berg 3rd so the bearing can rest against it. Basically, make the Berg small 3rd replace the sleeve on the Berg large 3rd, only a smaller, 1mm less diameter version. You would need to match what HR does as far as sizes. I dont know if this made sense to anybody. LOL

That just made my simple solution sound vastly complex:ror:

So HR big 2nd is of larger diameter than Berg large 2nd? And thus, it contacts Berg 3rd?

Can you post some comparative pics? Is this something a dremel could do or is some precise lathe/machine work required? I think I'd really like the ability to running pinions with the mini pullers.

**EDIT** Looking at the link Chris posted, I think I know what you mean now.

Disregard the fact that I am using the HR gear pic for refernce, but you mean the large HR 2nd will contact this cicrled shoulder on the Berg version 3rd?

 

[Erik D_lux]

Yep, that part you circled has to go.

Now that I thought about it more, all you would have to do is cut that so its flush with the gear and then I think you could get away with some locktight on the small 3rd and the bearing that goes in the case on that side where you cut that sleeve off. I thought that the bearing was helping position the gear but all that sleeve is really doing is holding the bearing in the case and making sure it does not fall out into the gears.

If that does not make sense let me know and I will try and get some pics.

 

[TSK]

Do you think the shoulder on that big 3rd can be turned down to clear, or does it have to be completely removed?

 

[Erin]

doesnt that shoulder also set the depth of the gear, so it doesnt ride against the next large gear? or does the shaft length do that? I cant remember on mine exactly.....

It sets the gear depth omn the shaft & prevents the bearing from falling out of the case. But Erik was suggesting removing it, and just loctite'ing the gear on the shaft & the bearing in the case.

Its really close, I think that sleeve is only 1mm thicker on the diameter, .5mm wall thickness so, not much to take off. I think youre just best to remove it.

The bearing could fall into the case and the 3rd large gear could move just a touch until the back until the large 3rd hits the front of the large 2nd. I dont think the gear moving back would be too big of an issue but I think locktite on the 3rd gear would solve both issues.

 

[Erik D_lux]

Ole Stubs gave me a killer idea (that took me forever to get around to). An all delrin piece that replaces the hex, hub, set screw and wheel nut.

Old setup 12g

New setup 4g per side

32g lost! Wow. That is in exchange for a 475 hub. You would lose even more with a bigger hub. Everytime I think there is no way to pull another ounce out of this car there is always something. Thanks for the idea Stubs!

Another huge benefit is that I am now rich with VP hubs

 

[Chris_The_Battery_Man]

So is the pin just driving the new hub then? I would be interested in seeing how it holds up.

Perhaps if you cant keep the stock pin from spinning, you could put a pin it all the way through the hub. Or perhaps you already thought of this lol

 

[Erik D_lux]

Stock pin spinning? I dont understand.

I put about 7hrs of drive time between my 2.2 and super with zero failures this weekend. "thumbsup"

 

[Erik D_lux]

Speaking of running this weekend.... I took a couple of pics for other various reasons. Might as well stick them in here.

Fun line, mildly hard. You can see my rear tires are already a couple inches off the ground. I was able to finish it off with some work though.

This line was actually really hard. I accidentally got it probably the 3rd time and then it took me quite a few tries after that.

All in all, I think I am happy enough with the car that I am not even tuning it for a change. We will see how long that stays. LOL

The bearing could fall into the case and the 3rd large gear could move just a touch until the back until the large 3rd hits the front of the large 2nd. I dont think the gear moving back would be too big of an issue but I think locktite on the 3rd gear would solve both issues.

Why not remove that and add a 4mm cut on the 3rd gear shaft and use a 4x10x4 bearing instead? Same purpose seems to make sense to me.

And when will these hubs be available for your loyal customers to buy? :mrgreen:
