Dear VW-friends,<\/p>\n

 <\/p>\n

as you know from a previous posting I disassembled the Samba\u00b4s front axle unit before I\u00b4ve send the front and rear end of the Bus to Mark. A front axle assembly of a classic aircooled car is a complex device. Many of its individual pieces can break or at least wear out: torsion arm leaves, the torsion arms themselves, the king- and linkpins, the brake backing plates, the wheelcylinders, the brake shoes, the wheel bearings, the drums and many small pieces as well as the basic body of the axle beam itself.<\/p>\n

So I thought it would be a good idea to dissemble the whole unit to the very last screw. This way I could control all components and repair or replace them in case it would be necessary. One damage was clearly visible right away: the big brackets between the lower axle tube and the body of the Bus were rusted off, so there is a need of welding at least this. But I expected a lot more of work or even worse: the conclusion that the axles body is not repairable anyway cause of rust. But to end up with this conclusion we have to disassemble all the components first. So let\u00b4s start the job, disassembling is not too complicated; this is a job I can do. All I need is being careful not to brake more than what is already broken.<\/p>\n

\"\"<\/p>\n

This is where we start from. A original Barndoor axle, the brackets are rusted away, but at least it is complete (the right steering knuckle I removed already weeks before)
\n<\/strong><\/em><\/p>\n

 <\/p>\n

I wanted to do the job in an organized way: from the outer to the inner, beginning with removing the brake drum. But in opposite to the rear drums both of the front drums didn\u00b4t turn a single millimeter! OK, let\u00b4s remove the grease cap and see if there are any surprises.<\/p>\n

\"\"<\/p>\n

Totally blocked!
\n<\/em><\/strong><\/p>\n

\"\"<\/p>\n

This one looks as it wasn\u00b4t opened since the day it left Wolfsburg<\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Everything\u00b4s looking normal here<\/em><\/strong><\/p>\n

 <\/p>\n

 <\/p>\n

How to remove a totally blocked drum? A look into the VW workshop manual is always is good idea. So what advise can the gentlemen in Wolfsburg give us?<\/p>\n

\"\"<\/p>\n

Pfffff\u2026. I don\u00b4t have the \u201cextractor VW 202\u201d, neither the tools VW 202 c, d and m-T. But looking at picture of the extractor gives me an inspiration to construct something similar as this tool by my own. Constructing this extractor needs to sacrifice a 5×205-wheel. I will check my stock of these wheels later to choose a bad one which I can sacrifice without regretting. For now I decide to continue the disassembling by removing the complete steering knuckle unit with the drum and brake system mounted.<\/p>\n

To remove the steering knuckle unit I have to lose the drag links. So let\u00b4s clean the drag link ends carefully.<\/p>\n

\"\"<\/p>\n

I am not too surprised finding the nuts of the draglinks secured by the very old style, original cotter pin. As I am confirmed in my believe that the Samba didn\u00b4t run a high mileage by many other hints while disassembling, this situation here is another proof.<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Does look good, doesn\u00b4t it?<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Also this side looks as it wants me to invite: “Don\u00b4t replace me! I was with the Samba all the time and I am good enough for another 66 years.”<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

As Bender said: “Another job well done.”<\/strong><\/em><\/p>\n

 <\/p>\n

Maybe I will use the original draglinks again. I will have close look on them later. Let\u00b4s continue now with the disassembling!<\/p>\n

Removing the shock is next on the list. But being careful is very important here. The upper fixing screw of the shock often brakes when apply too much force to it. In addition to the need for a new screw (which is not so easy to get, cause it is not just an ordinary screw, it\u00b4s a VW-specific item with an own VW spare part number!) the rest of the broken screw is stuck in the body of the beam and removing this without destroying the thread is a hell of a job!<\/p>\n

So applying rust resolver is a must here, but this is not enough. The risk of breaking the screw is still too big. To heat the whole thing up is always a hopeful way to lose a rusted screw. So let\u00b4s try it!<\/p>\n

\"\"<\/p>\n

NEVER try to lose this screw just by applying lots of power to it as the risk of breaking it is by 90%. You will see the later why\u2026\u2026<\/strong><\/em><\/p>\n

 <\/p>\n

 <\/p>\n

\"\"<\/p>\n

It doesn\u00b4t work all the times, but heating up raises the chance of losing the screw without breaking it big time!<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Gotya! See, the thread of the screw is way smaller than the rest of it, so the screw got kind of a predetermined breaking point.
\n<\/strong><\/em><\/p>\n

 <\/p>\n

Now when the shock is out of way, we got room enough for a cleaning job.  Here you see my two pupils Mert and Lars, two teenagers send from a local school to sneak into the \u201creal professional life\u201d. Strange idea to learn something about today\u00b4s professional life in my odd enterprise.  I am a bloody bad teacher, I learned my profession on the junkyards of Bonn and Los Angeles, what for hell could an analog dinosaur as me teach a teenager today? Let\u00b4s face it: they could teach me! For example how to handle a smart phone\u2026.<\/p>\n

But sure I don\u00b4t miss the opportunity to show young people that there is more you could use your finger to but wanking and a mouse click. For example remove some antique dirt of the boss\u00b4 very personal car\u00b4s the front axle.<\/p>\n

Just kidding. They also worked in the goods-in, the packing station and the warehouse too. But, believe it or not, working on the Samba project was their favorite  -at least they said so.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

Mert, would your mum agree that this bright jacket is a smart choice for this kind of job?<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

“And now, boys another epic moment: removing the torsion arm leaves covered all over by 66 year old grease! Can you smell the history?”
\n“Aaaahhhhh, hmmmmm, well, OK, Florian.”<\/strong><\/em><\/p>\n

 <\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

OK, this is a very unusual way to pull out the torsion arm leaves, but this side\u00b4s torsion arm is stuck and I don\u00b4t want to hammer it out while the fragile leaves are still in place.<\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

One last torsion arm to remove and we can continue to clean the beam\u00b4s body.<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Isn\u00b4t this more fun than paying attention to a math lesson? And, believe me, the girls they like men who can handle a powerful device correctly\u2026  <\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

The result of the cleaning process: this beam\u00b4s body is way better than expected! No rust hole at all.<\/em><\/strong><\/p>\n

 <\/p>\n

Now let\u00b4s clean the torsion arm leaves to see if any of these is broken. A broken torsion arm leave is not a rare event at all when restoring an aircooled VW……<\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

 <\/p>\n

\"\"<\/p>\n

None of the leaves is broken!<\/strong><\/em><\/p>\n

 <\/p>\n

 <\/p>\n

As the Samba hadn\u00b4t had any wheels mounted in the front when it was found, the threats of the front drums are very rusty. To clean the threats up and save them I have to screw in some wheel bolts very carefully. Sure the bolts suffer from this procedure and I better don\u00b4t use them again. I sacrificed one bolt for each threat, but as I have enough of the bolts cause of hundrets of bugs I stripped since 1986, this isn\u00b4t too painful.<\/p>\n

\"\"<\/p>\n

 <\/p>\n

OK, now let\u00b4s continue the disassembling by removing the brake drums from the steering knuckle to have a look at the front brake system.While Mert and Lars cleaned up the beam\u00b4s body I tried to make my idea of a self-made extractor real. This is what I ended up with:<\/p>\n

\"\"<\/p>\n

May I present you? Florian\u00b4s self-made extractor. Will this \u201ctool\u201d work?<\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

It will.<\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Remember this great Toy Dolls\u00b4 song  \u2018Spider in the dressing room\u2019 ?<\/em><\/strong><\/p>\n

 <\/p>\n

You know me, I always try to save as much patina as possible, but there is a red line: the brake- and steering system. If the engine blows up caused by too much patina it\u00b4s one thing and it\u00b4s just me who has to suffer. But if the brakes or the steering is going to fail, others will suffer caused by odd addiction. This must not happen, so let\u00b4s say \u2018Good by\u2019 to the spider\u00b4s mesh and clean the brake system up!<\/p>\n

\"\"<\/p>\n

Pretty, pretty original! Correct four bolt wheel cylinder, wire secured bolts, this Samba didn\u00b4t drive too much mileage in its life for sure!<\/strong><\/p>\n

 <\/p>\n

 <\/p>\n

\"\"<\/p>\n

Look at this! Haven\u00b4t all of us seen this area much worse in our lives?<\/em><\/strong><\/p>\n

 <\/p>\n

What a nice surprise! So many original parts in place, the effort of needed repairing is way less than I expected. Sure the wheel cylinders needs a lot of attention, but \u2013hey!- they are there! The brake shoes are the correct ones and we can surely use them again when we rivet new brake linings on. The drums need just a proper cleaning and \u2013just for the safety- a set of new wheel bearings.<\/p>\n

Also the steering knuckles don\u00b4t look too bad. But I will send them to Christian Grundmann\u00b4s mechanic Marcel for inspection. Let\u00b4s see what he will tell me.<\/p>\n

\"\"<\/p>\n

Another all original tie rod end. It\u00b4s worth a try to save it too.<\/em><\/strong><\/p>\n

 <\/p>\n

\"\"<\/p>\n

So, let\u00b4s heat it up!<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Replace an all original wheel cylinder by a more or less working substitution? No way! I will rebuild this one here. Stay tuned on this channel and I will show you how.<\/strong><\/em><\/p>\n

 <\/p>\n

\"\"<\/p>\n

Saving every little component is essential during a proper disassembling. Bagging it up with detailed markings too.<\/strong><\/em><\/p>\n

 <\/p>\n

Now the whole axle beam unit is disassembled up to the very last screw. There is one golden rule beside care and tidiness: NOTHING must go in the trash, even this parts which are obviously broken. Maybe you will need them later, at least as a sample.<\/p>\n

Saint-Exup\u00e9ry was very right: You always have to clean also the dormant volcano, cause you never know.<\/p>\n

 <\/p>\n

 <\/p>\n

have a nice weekend!<\/p>\n

 <\/p>\n
