Hello,

I am Florian, from France, recently registered on your website ; Working as a mecanician, and bikes freak, specially for the old two stroke, I'm actually on the restoration of a Kreidler Florett, the K54/53B from 1973, since a year.

My father had also a Florett RS and an Eitank on the 80s. I looked for years, until I found one, in my region. One day after, it was mine !

Afbeelding
Afbeelding

A lot of parts were missing, It hadn't Handel, Airfilter, cables needed to be replace..etc

The fuel tank was full of rust, and all chromed parts needed to be polished. The wheels were pitted.

First, I dismount the bike, to make a list of what needed to be done.

It was supposed to be a check, it has become a full restoration.

The original signal orange paint wasn't holding no more

That was the tank before job

My bike may had an accident in her life

My father welded the nock, the foot rest were replaced

Here is the opening of the front vork

Conic rubbers weren't here....Seals were out of service

Dismantling Of the Shokbrekkers

Springs chrome are pitted

Some new 6201...

And old new brake shoes
Afbeelding

My rear drum isn't a Kreidler. I've the luck it fit perfect (Same wide) but i don't know from where it comes...Puch ? Hercules ?
Afbeelding

After a few hours of polish with my father, chrome parts looks much better :)
Afbeelding

The frame and all other "painted parts" are ready for the paintjob > The rear mudguard is a new, my old was cut, like a cup racer.
Afbeelding
New foot rest too ^^

While waiting for the parts, iv'e tried an electrolysis with soda to attack the rust.
With and old Computer 12v supply (Normally connected to a motherboard for the processor) linked to an inoxydable pin and the tank, a big part of the rust left.
Afbeelding
Attention to isolate the pin... I have to do a Restom process to make it correctly

And comes the job on the blok, a B15/47 of 1979
Afbeelding
Afbeelding

Everything was dismantled. The O-Ring was missing on my selector shaft, Oil seals were leaking. Because I haven't any idea of much kilometers my kreidler did, and because of some missing parts, im revising the complete thing.

My father did me a support for the cases, to make the job easier
Afbeelding

As a "young kid", i've made the "KK" colouring :p

Cases were cleaned at father's work ; I've sand cilinder and head, and my boss made a new honage. After measurement, my cilinder is 40.01mm wide. I've found an original Mahle J Piston.

Meanwhile, after paintjob, Satin black parts ready to be stiched together.
Afbeelding
Steering bearing, rubbers, type plate and swingarm bus are new.

The levers aren't from Magura, Lusito copy, and the throttle handle is a sort of Tomaselli, not Original, but fills me :)
Afbeelding


Without any chrome factory in my region, ive bought new shokbrekker springs
Afbeelding

This is a "blank" montage, just to see...the fork wasn't finish, I wait still for my sport oil seals
Afbeelding

Overhauled shokbrekkers
Afbeelding

> Ive bought all my cables on Kreidlerparts and Kreidler Portugal, and they are all much too short....or rather the sheath is too long, can't connect to levers or brake cam..
I will do cables mine...


Here's some bearing replacement, Today.
Afbeelding

Afbeelding
The clutch seams to rub the carter in the past...

This week i've cleaned the 1/20/59 and overhauled the thing. New seals, and a bit of polish (Just Belgom with hand..)
Afbeelding
Afbeelding

And the complete intake system
Afbeelding

My new Airfilter box is longer as my old original, but cracked...it makes 19.5cm long....a bit too long I think...wanna see in a few days..

The Claxon wasn't present with my bike, I find one in my region. It's an Hella 17W, normally for 72s and earlier Kreidler...but I don't care, It works !
After a bit of sanding, it's like a new one.
Afbeelding
Afbeelding


I tried to sum up one year of work. Everything isn't present, I'de should rather register on Maarten the last year, before starting the job.
I enjoy to work on my Kreidler, try to do my best. I'm not searching the Original condition.

Like every restoration I suppose, there's unexpected stuff...My rear wheel is split ; Because of the bad shape of the chrome, and the need to balance the two wheels, i decided to buy new wires and two wheel circle to replace my old ones. I've also broke two new fork oil seal on the montage...without a press, I tried with a tube and my hammer...bad idea....

I've to finish the blok, paint cilinder and head, finish the front fork, and make a hole new electric beam.

This is what I translated and coloured ^^

Im crossing fingers about my Iginition coils, and hope everything will work.

I apologize for this long "novel"

Nice job and nice postings! However, next time maybe heat you carters in a (pizza) oven gradually instead of putting the flame torch on them?

Thanks for your answers, it makes me even more motivated ;)

How did you recognize me KJ ? ^^ I also broke my old seals because i didn't use a appropriate tool

viewtopic.php?p=591160 I thinked to use a press, but this method seams to be perfect !

But, those 57.06.22XP need the harmonica rubbers ? Sorry i didn't understand everything. Is it a montage of two oil seals per tube ? Also, one 57.06.22 (Normally Touren Model) and the Sport seal to prevent dust ?


P.S. For the carter heat, you use an oven to heat "homogeneous" ? My father put me the BO17 cages with Nitrogen. I just hat to put the 4 other bearings yesterday :)

Best Regards, Florian

I just remembered something about a customer in France ;-)

Just put one XP bearing in every side of the fork and it will be oil-thight.
Are you thinking of going Off Road or want to break very tight then mount 2x of the XP on each side.

No Harmonica rubbers needed, read the following first;
The newly produced "Sport Seals" are not as good as the old original ones. The outsidelook is as the original looked.
The new "Sport Seals" can be mounted on top of the XP Bearing...... after removal of the inside ( seal ) of that one.


Buy a (electric) stove for the future removal of the kreidler bearings....in the case of the flame heating you heat it to local....instead of it all.

Thanks for answers :)

The end result would not be like the original, note same paint, a multiposition handlebar, the rear light of earlier model...etc

I will order the new seals. Question, you mount it with tube and hammer, or a press ? Im hesitating about mounting sport seals above XP seals.

Today I've started to paint the Cylinder head
Its not finish. I've to make the other side, maybe one other paint coat, remove the scotch and polish the cooling fin edges.
Afbeelding

Ive a problem. I'm mounting the gearbox. Ive followed instruction auf the "Blau Montageeinleitung 5Gang". It match with my blok.

Afbeelding
Afbeelding

I think its correct, but not shure.. My problem : When ive replaced blok bearings, ive replaced the two bronze bus too (Kick Starter)
I cannot put the kickstarter/selector axis on my right carter, it didn't fit on the new bus.

Afbeelding

I know I must pull a bit the gears axis to put the Kick in, but that isn't the problem : The kick didn't fit on the bus. Those two bronze parts change was a bit useless I think, should better keep the old.

Any Idea ? It's like the new bus too small for the axis...

Thanks

Hello,

what is this tool ? I don't know, seems like the one for making screw thread. Should I heat the bronze bus to fit the kickstarter axis ?

For the ring 24, I have it :) Not present on the picture

Thanks

Ok, also it is normal that the brand new bus is a bit to small for the axis ? The left carter fit perfect on the axis ^^

Also not for today the carter close, but I prefer to make it good :) Ive to make measurement too, I find that my Gear axis (The one where we put the "tandwiel" 12, 13 or 14) as much "spel" when the two carters are closed...maybe need adjust with adjust slices..

Thanks for advices !

P.S. Ahhhh, the ruimer is an "Alésoir, en français" I've understood :) Like we us on sprooiers to make it bigger, but adjustable tool...ok :)

Hello,

this week my father find me a "Ruimer" ; The left bronze bus was thiner too. I've closed the blok this morning, with is overhauled crankshaft. Before closing :

Afbeelding

I've done some measurement. There is problems...
https://www.youtube.com/watch?v=_eaMb_t ... e=youtu.be

Afbeelding

On the main gear axis, i've a play of 0.3mm at least ! I have actually a 0.1mm slice (11.00.25) on this gear axis. May I re-open the blok to put a wider slice ? Should I buy the original adjusting slice or could I use strippable slices that I have like those :
Afbeelding


An other problem, I have ZERO play on the selector/kick axis, but a play of 0,02 - 0.03mm on the Crankshaft we just balanced....
https://www.youtube.com/watch?v=y-rZDCg ... e=youtu.be

May I rebalance the thing...? I will try on the right side


Thanks, Best Regards, Florian

Ive mounted those bearings :

> But with the original 28mm 37.29.11 lower cup

I don't understand where the problem is, I cannot put the handlebar support correctly, the distance between the middle tube and the two others is way too large

Is the 57.06.37 "Afstandring" always mounted on RS ? I thought he was the problem, but on every Kreidler I see on the forum, this part is mounted.
I will try again, maybe one ball is not right mounted.

Have you so much space between Fork and bottom cup as mine ? My new bearings are as the old ones.

Thank You

Hello

Thank you for advice, I will try again, maybe just one ball not correctly mounted, or the fork "stop"...

this week end i Tried to finish the blok. With the slices from Kreidler Service, I could adjust each axial play of the gearbox. Now it's closed. I just have few questions about the clutch.

When I've dismantled the bloc last year, I noticed that the clutch rubbed the right carter cover :
Afbeelding

I've noticed that on my clutch stick (15.07.12 Drukstift) many slices were mounted....Too much : 2* 1.5mm and one of 0.25mm....

I think it was a "tweak" to ride with old clutch disk without replacing them....

My problem is that I don't know how many slices I should mount. I've read that the 3 screw needed to be tight, and released of two turn

If I mount the three slices I had on the past, the clutch rub the carter cover. If I mount a 0.25 slice for exemple, the "drukstift" is not opening the disks...

What is the setting method for the clutch, or what is the space required before druckstift is moving the druckplate ?
Afbeelding

Thanks, Florian
