I agree completely ... Don't cut anything until you have what you are going to use ...

I do think your set looks good above ... Looks as if it would handle a lot of torque ....

Again,, I'll get a photo or two of the "Johnson's " up here on the site before the week is out ....

I tried to get in touch with John a few years ago.. I was trying to find out who he got to grind his stubs ...

For a while he was selling 1.68 axle sets ... We bought one set from him way back there.... (Still in perfect shape) ,,,

He was using an OEM top gear(16T) ,, but the best I could tell,, a machine shop somewhere was grinding out the 27 tooth stub .....

I was wanting another set,, and was ready to run down whatever he was doing and copy it ...

I got lucky,, and with a couple of friends here on The Samba, ended up with almost 2 more sets that were factory NOS ...

I got a phone call the other day,, I had to travel overseas again,, didn't get to take the photos I promised earlier,, will be home mid November, and will snap the photos of my adapters...

It would be pretty cool if you could make a few sets,, seems like there are some folks here that would like to have a set .....

Two years ago,, I started to make a few sets,, the phone rang and my personal shop has been locked down for two years as I've traveled...

One thing I'll say about those Johnson adapters, and everything else I bought from John,, It's still here,,, it took a beating,, and it still works !

Here are a few pictures of one of the two NOS sets I have scored from Samba members over the last year.

Image may have been reduced in size. Click image to view fullscreen.

And here is a link to a build I am doing using one of the sets.

Thanks for the pictures and measurements Joe.

If and when I do reproduce them, they will not be exact replicas. They will have some minor changes to modernize a few things and fix a couple of things that I think are problem areas.

okay.. so i'm still confused after this even...

i want the lift.. my car is an around town car and cruise through the woods once in a while for fun, nothing major... i just want lift w/o the tire lean... will the redux boxes bolt to my stock 68 Swing axle trans in the beetle or is this a swap everything? if so what all do you need to do the swap? this stuff is so confusing, and living on the east cost no one really knows much about this type of stuff..

OK, It's been quite awhile since I last posted here but recently got back to my Baja project after finishing a tractor restoration and a CJ-5 build sooooo.

When I left off I needed to figure out how I was going to incorporate shock mounts for the adapters I built. I also wanted to build a truss to stiffen the transaxle forks. The truss will help control any deflection of the forks and help minimize some of the wheel hop. The truss also incorporates the upper shock mount as I had to use the OEM mount to tie the truss in.

Truss fabrication:

Lower shock mount:

Truss and shocks installed:

This shot shows a view of the nut welded to the inner, lower bearing cap and can be pulled to replace the bearing without having to unbolt the adapters or spring plates: Smile

Very nice set-up, great workmanship and design! Applause

WHEW

That's kinda what I thought. He was talking about the stub axle needing to be torqued. When ever I hear "preload" I always think Timkin type bearings. It was sooo long ago that I rebuilt those RGBs that I wasn't sure what I did or didn't do inside there. I know I'm usually pretty methodic with these things but in my old age I'm never quite as sure of myself as I used to be. Laughing

Since I've finished my tractor and my Jeep the Baja is my priority project right now so we should see more timely progress. Lots to do yet. Thanks for the Kudos!

While looking through the June 1989 issue of VW Trends, I spotted an article about John Johnson Racing.

At one time they offered a disc brake kit for reduction boxes. There were no details given as to what calipers or rotors were used, just 2 pictures.

My Baja Bug has Bus reduction boxes mounted in the "laydown" position using John Johnson adapters.

For years, I have had to unbolt them from the spring plates and tip them down in order to drain them or fill them with gear oil.

I figure there must be a better way.

When mounted in this position, the fill plug and drain plug are no longer facing up and down. They are now front and back making it impossible to fill to the correct level.

I'm thinking of drilling and tapping a hole in the location shown in the picture. Maybe something small like 1/4 NPT. Something just large enough to fit the spout on the gear oil bottle into.

I'm wondering what other people with laydown reduction boxes are doing. Has anyone else tried this? Will the hole weaken the outer half of the reduction box?

So, I was cruising the FleeceBay and stumbled across a set of RGB's that have been converted to a U-Joint yoke. Wow! Being the sloppy sniper that I am, I instantly bid on them in my excitment, then started to worry that I had jumped the gun and some one will wait and snipe me out of them. So, being that smart sniper, I ran my bid way up to what was most likely more than what they are worth, (My MO is to buy high, hold onto for years and then sell low).

To My amazement, no one bid on them and I have a set of RGB's that I can now think up a project to build around, (my second MO is to buy one part and dream up some project that the part can fit on).

I am told that the yoke is from a IRS Chevy Corvair and the one remaining bracket is to adapt to a Corvair. I am thinking a mild Baja, with a SSC 3.88 IRS and into these small nut RGB's with a custom made tubular trailing arm that this RGB will bolt onto. Eventually.

I found this video of a guy demonstrating reduction box wheel hop in a Baja Bug.

Link

This guy appears to have IRS reduction boxes like some of the Brazilian Buses had:

I'm picking up a big nut transaxle package tomorrow to put in a Tow'd. I have a question, what would anyone's thoughts be about using Bugzyla RGB adapters along with Atomwerks 2 1/2" raised spring plates?

I can see the Bugzyla adapters appear to be designed for notched spring plates which rest at a steeper downward angle than stock and the adapter mounts the RGBs at an angle to the spring plate. So maybe an adapter similar to the Bugzyla design but for a Atomwerk raised plate, which intersects the RGB approximately perpendicular?

I also think that wheel hop might be caused by the springplate flexing, bowing, loading and unloading under acceleration and that thicker springplate steel, like what Sway A Way uses for their heavy duty spring plates, might take care of the wheel hop issue.

The pictures below are just for illustration, they're not mine

joescoolcustoms · Posted: Sat Jun 21, 2014 6:41 pm Post subject:

I have wondered if that is where Atomic got the idea to produce the drop plates. They look really similar to a set of drop plates I had for adapting the RGB into a Type 1.

The thicker plates may help some of the hopping, but I doubt it. The Splitty bus has a seriously thick spring plate that does not warp under load and they still hop. The may reason they hop is the instant center of the RGB set up. The John Johnson no hop kit changes that instant center and eliminates the hopping. Laying them down also changes the instant center having the same positive resulting effect.
