Hello,

I got the Rzeppa axle cleaned and ready to pack.
It looks great, likely because it was a replacement one put in after WW2.

I will get it packed and slid into position !
Resized_20220802_200946.jpeg
Here we can see where I primed and painted the end of the new spindle. I did this to protect it from any future rust and corrosion.
Resized_20220802_201245.jpeg
I taped the area where the seal goes, and used a paper towel role to cover the spindle shaft, before painting, it worked great !
Resized_20220802_193045(1).jpeg
Here is the grease packed Rzeppa axle unit being slid into the axle housing and into the spindle housing that is also packed full with the NLGI-1 special grease for the Rzeppa joints.
Resized_20220802_195311.jpeg
It is a little messy, but the grease was pushed into all corners of the spindle housing and then squirted out the bolt holes as the axle was pushed all the way into the pumpkin.
I added a thin film of grease over the length of the axle shafts to prevent rust before inserting.
Also I added a film of grease to the inside of the spindle tube for the same reason.
It went very well !!
I cleaned up the grease on the mating surface for the new spindle, then attached the backing plate and spindle to the housing.

Resized_20220802_202331.jpeg
Here the restored brake backing plate and the brand new spindle have been bolted on nicely.

I finished it up just as a huge storm rolled in tonight !!
The paint looks dark, as it was about dark , when the pictures were taken , and with the storm approaching !
Tomorrow , I will install the grease sweepers , the brakes, the hub and brake drum, as well as the brake line guard .

Best Regards,
Ray

Hopefully your spindle threads are all good ...
Hello Jeff,

Well, you called it, Bubba strikes again :shock: :shock: !!

I was making good progress today, and I installed the grease seals and retainers.


Before I started I threaded a good bolt in all the holes for the felt grease seal retainers,and everything seemed ok, but once I get everything into position, and actually tightened down under load, I find one hole that is stripped out, at least the Ford fine thread bolt won't tighten down.
Resized_20220803_192543(1)(1)(2).jpeg
Every other bolt tightened down, and set properly, except this one !
It is just that the hole is too wallowed out, and that wrong bolt that once was used, muffed it all up.

I am looking at maybe a Helicoil ?

Do you have any ideas ?

I think I can get this repaired without having to take everything apart again !!

UPDATE : I was able to tap the hole with a correct size fine thread tap, and repaired the damaged threads.
All ok now :D :D :D !!
An F marked bolts holds in now !!


Just another little item to repair :D :D :D


Best Regards,
Ray

I just did that exact job with a Heli-coil last week. If you do it "in situ" you need to be careful that you drill and tap square to the front surface and get all the swarf out of the knuckle. If you remove it and use a drill press be sure to lay it on the plate face down and drill and tap from the back (so that it's square). You'll probably have to cut a couple of coils off the Heli-coil as even the shortest (commonly available) are too long and a loose "wire" isn't a good thing to have in the CV joint. Champfer the hole on each side as slightly as possible, but definately champfer it to prevent a little piece from breaking off. Install the Heli-coil from the front and after the "end" is under the starter thread ever so slightly, if the back end is also inside the threaded area snap off the tail. If it isn't perfect, keep screwing it in until it comes out the other end and adjust the length and screw it in again until it's correct.

Hello Jeff,


Wow speaking of the parallel jeep universe :D :D !!
Our jeeps have been sharing very similar repairs :D :D :D

I would like to repair it in position.

Do you happen to have the size info on what Helicoil kit I need to order , and the drill bit size needed as well ? :D ?
It will be good to post that important information here to document it for future G503ers that come across the same situation !!

I was getting so close to using your F script bolt you sent :D :D

Best Regards,
Ray

Over the years I just ended up with all the common heli-coil kits that cover 10-32 to 1/2" in fine and coarse threads along with a couple metric sets. In fact, "in the beginning" I would just buy what I needed but after learning the folley of that (not having the size on-hand when I needed it cost more than buying a larger kit that had all the sizes I'd likely need for jeep related work). The size for that spindle bolt is 3/8-24 but they don't list one as short as you'll need so you'll have to trim it to about four or five "turns". Drill it to 25/64" and barely champfer (both sides if possible). I often champfer by hand with a larger drill bit, no power, just hold the bit in my hand and turn. Here's one source for the inserts; https://www.mcmaster.com/91732A524

The special installation tool makes installation much easier but you don't need to spend big bucks for one hole. You could modify a cheap bolt with a "slice" from a cut off wheel (see the picture in the link below) to form a lip for the tang to catch. Breaking the tang is done with just about any object that fits in the hole that you can smack; the shock load snaps it off. You have no choice but to buy the heli-coil tap though.

There's off-brands like Re-Coil, etc. but Heli-coil is like Kleenex, everybody knows what you mean. Other types of inserts, like I posted a few posts above, or time-certs, are for other special needs and all have their place.

Here's a kit just for 3/8-24 thread; https://www.mcmaster.com/91732A932/

Hello Jeff,

Wow that is great information !!

Thank you so much, I will order the correct kit, and get to work on fixing the damaged threads.

You certainly have a lot of jeep building experience, and I greatly appreciate you sharing so much great information with me , and all the G503 !!!


Outstanding 😁😁😁😁 !!

Update : A kit is on the way, should be here in 2 days.

Best Regards,
Ray

Hello,

This morning I blasted and primed the brake line guard.
It has a couple nice F scripts on it.

I will fill in the pitting then paint it .

Hello,

Well while I am waiting for the Helicoil kit to arrive, I started to clean up the steering column and gear box.

However, this is certainly not a Ford gear box, it is a Ross.

Does anyone have any ideas ?
Or know if this is from a Slat Jeep, or a regular MB ?

Resized_20220804_131713.jpeg
Now looking online, I am thinking this may possibly be for a Willys slat grill jeep ??

Resized_20220804_133047.jpeg
Resized_20220804_133044.jpeg
This is the column that was on my slat grill jeep that was a Moore Equipment Company rebuild in March of 1945.
The slat jeep was placed onto the 1943 frame that I am using to build the 1943 GPW .

Am I right to guess that the slat steering column and gear box were transferred over to the GPW frame during the rebuild ?

If so, that is great as I will build the slat back together on a slat rolling frame that was picked up a few years ago for this purpose.

Now I will have to get a Ford steering column.

I may have one, or I can borrow one from another GPW, but may just look for another one.

Ray

Hello,

I looked around and found a steering column and gear box, that years ago I picked up from a big mud puddle next to a scrap metal pile, when I was buying 2 jeeps.
The seller said I could have it, so I was happy to save it.

So now these may moons later, I need a GPW unit for my project and was hoping this was a Ford column .
Resized_20220805_141511.jpeg
Well.....
Happy Days are Here Again !!
Resized_20220805_153913.jpeg
This is a GPW unit 😁😁😁
!!!
Here are some pictures as I cleaned it up.

It does need a full rebuild and also a new sector shaft !
Resized_20220805_153932.jpeg
These threads look pretty twisted !
Resized_20220805_153944.jpeg
Resized_20220805_153919.jpeg
This will be a nice piece to save , rebuild, and restore !!

Yet another lone part, that was found, saved , and now will be rebuilt to like new again and returned to service !!

Best Regards,
Ray

Hello Jeff,

I don't know, but bubba managed to do it !!!
A GPW I got from the seller when I found this had some giant car steering column installed.

I am hoping the worm gear is ok, but will find out once the case is opened .

I found a USA made sector shaft online, and just ordered it, so it is on the way.
I will investigate the worm gear and shaft that is available in France,
in case I need one.
If I do need one I would want to get a WOF, well made French unit.

I don't know if any are made in the USA ?

But I can turn the steering wheel end, that has perfect splines with my fingers, and the sector shaft turns nicely all the way left, and all the way right.

So maybe it is ok.

I will find out once I take it apart.

I have a rebuild kit from Ron here already to rebuild the steering box.
Didn't see any sector shafts on his website.

Ray

Hello Jeff,

A quick update :D :D .

The new helicoil kit with drill bit, etc. arrived, but I missed your pointing out that these were for the spindle bolts !!

The damaged thread issue that I have is not a spindle main bolt, but a bolt for the felt grease seal retainer, which is a way smaller bolt !!
But now I have a useful set of tools for any future needs !

The good news is I figured out a way and fixed the threads after closer study !!
I will post that happy result next !!

Best Regards,
Ray

Hello,

I managed to discover something about the stripped out bolt on the felt grease seal retainer !!
I removed the retainer and the bolts, getting ready to helicoil it, but the helicoil kit I ordered were for the larger main spindle bolts.
The retainer bolts are much smaller.

Looking at the current bolt from the suspect hole, I noticed that it too, was not an F bolt, and also had ever so slightly stripped threads.
Resized_20220809_113636.jpeg
So I took a look at my new tap set, and found the correct tap to match the fine threads on the bolt, and hand turned it into the hole using a pair of pliers, as the tool handle wouldn't fit in the area.
This was just enough to restore the threads in there, for another F script correct bolt to tighten down nicely.

I was so relieved with that repair !!!!
That is all it needed !
Resized_20220809_144002(1).jpeg
I then added the grease seals and retainers back into position, but kept the bolts pretty loose as I had to install the brake line guard and the steering spindle arm into position, while lining up the king pin bearing.
That went perfectly, and then I tightened down the retainer bolts holding the felt grease seal.

I did tighten everything down, before tightening down the bolt into the tapped hole, that had the damaged threads.
Resized_20220809_155021.jpeg
Resized_20220809_155025.jpeg
All is well now, and the restoration is back on track again !!

Next step : I am replacing all the king pin studs on the driver's side of the axle assembly.
One was stripped, the others looked suspect as well !!


After that, the hub will be going onto the new spindle !!


Best Regards,
Ray

Well, there could be some good news....the kingpin studs are also 3/8-24 and if the hole is stripped you're ahead of the game! (I just did one of those on the opposite side from the one with the stripped spindle threads).

Hello,


I have replaced all 4 king pin studs on the driver's side.
Resized_20220809_182801.jpeg
I doubled nutted them, and turned them out, one at a time, with no problems.
Resized_20220809_163804.jpeg
One was clearly stripped, and it was not even the correct fat base, or wide shouldered stud, that it should have been !!
Remember, 2 of the top studs are wide shouldered, and at opposite corners to each other !

Since it came out so easily, and I had plenty of new studs, nuts, and washers, I decided to get rid of them all.

They were junk, or close to it.
Resized_20220809_182801.jpeg
Resized_20220809_164048.jpeg
One even looked twisted ?
Resized_20220809_164555(1).jpeg
Here is a brand new, or nos, wide shouldered stud.
Resized_20220809_184437(1).jpeg
Resized_20220809_184429.jpeg
All is good now :D :D !!
Resized_20220809_190502.jpeg
The new studs were seated, and look great !!
The restored brake line guard and spindle arm are now installed and tightened down.

I will paint the primed nuts once the primer is dry.
Resized_20220809_203202.jpeg
