Halo my friends

In another topic
https://www.marklin-user...4-3048-BR-01-restoration

I saw you the restoration of a 3048.1 and 3048.5

They are working smoothly both, but are not digital.

So I decide to do the conversion.

The task is:
1. DC high-efficiency motor (5 pole if possible)
2. mSD3 Decoder
3. LED lights, front, rear, cabin, gears
4. Smoke generator (already installed but for analogue operation)

The problem with 3048 is that there is no motor kit available for this motor (motor cover actually), and you need to do modifications to the 60944 motor (type I) by yourself.

After the discussion in the forum, and the valuable opinions of many of you, with previous experience in this loco, I decide to start with 3048.5 with the easy way.
Marklin some years ago make a replica of the original 3048 with catalog No 30080. In this loco they used a variation of the 60944 motor with a different motor cover.
This motor is still available as a spare part from Marklin No E188838, costs 25€ on Marklin shop but you can find it around 20€ in other e-shops in Germany.
I order it from Marklin with other items... and in 5 days arrived in my door in Athens!!!

IMG_0001_resize.JPG
IMG_0002_resize.JPG

Inside the package there are:
2 x 601460 brushes
1 x 210882 Magnet
1 x 214118 Armature (7 teeth)
1 x ???? Motor cover
1 x 212230 Solder point
2 different screws

IMG_0006_resize.JPG
IMG_0007_resize.JPG
IMG_0008_resize.JPG

So we have 2 pair of brushes but no any Interference suppression choke!!! why???
No problem I have many !!!

The same motor is for 3008 and 3026 and 3193 Primex variations

So I will go on with the conversion

Best regards
and a big THANKS to all of you for your help!!!!

Costas

I did the digital conversion on my 3048 using the kit E188838

I used an ESU decoder with a 21-pin adapter that has a high current output, but still need to figure out how to install the smoke generator. Maybe the relay is the solution. I installed the speaker in the coal tender.

For the smoke generator there are to solutions
1. Leave the original contact in his place (insulated from the body) and don't solder anything to the lamp socket. Use another 2 pole socket for the light. Then connect the wire from f1 to the original contact. Is done!!! The return is from the body.

2. Solder the f1 wire to the smoke generator small wire

I prefer the first solution

I did have the smoke generator initially working by getting a generator that had two wires already connected. I then installed a small 2-pin plug to these wires which would connect to a 2-pin receptacle that was connected to F1. the wires broke off the smoke generator after several dis-assemblies and re assemblies. Got to come up with another solution.

When I will complete my conversion I will publish the photos so you will understund what exactly I mean.
But that's my plan.

Photo of the front of the 3048 before the conversion.

Front light.JPG

As you can see original the outside of the lamp holder is insulated from the frame and a black wire is connected on it.
This wire is coming from the main soldering point and has the current of the third rail.
The lamp holder is connected with the cooper contact spring for the smoke generator (It was factory fitted in this Loco).

So the only thing that you have to do is unsolder the black wire (already done) and in the same place solder the f1 wire (Br/Yel in Marklin). Return is not needed (blue wire in ESU, orange in Marklin)). Stick in the cover a 7226 smoke generator and that's all.

The Light is already as I can see connected to to the gray and orange wires insulated from the cover.
You can press the new lamp socket into the old lamp holder.
The old lamp holder as you remember is connected to the frame with a small screw.
Attention to the insulation paper. (better to check that there is no a short circuit with a multimeter before run the Loco)

Regards

Costas

Second step: Very good cleaning of the Loco
Gears, axles, wheels, frame everything with Isopropyl Alcohol with patience.....

The result:

IMG_12151_resize.JPG

IMG_12153_resize.JPG

Oiling of all the moving parts carefully

Everything is looking fine, is working fine.

No mechanical problems with all the parts of the gear drive, axles, wheels...

Ready for the next step the installation of the new motor.

Thanks

I don't ever recall seeing a circlip on the end of the rotor shaft before - but then I don't have any experience with this model.

Is that a standard motor shield for this motor?

The circlip is quite common in the LFCM motors.
The motor shield is not standard. Is metal and you can find it also in F800, 3026, 3008, 3048, 3193.
This is the difficulty in the conversion of this Loco.
The motor shield from the 60944 set does not fit.
So you have to do modifications by yourself.

But as you can see in details in the start of this topic at the moment you can use the E188838 motor set that fits exactly.
Is not bad idea to buy 2-3 motors for future use in case that this set will be discontinued.

The 3rd step is the placement of the new motor, from the E188838 set.

I had already paint black the parts of the field magnet that are visible with the body on...

IMG_12155_resize.JPG

The placement of the E188838 motor is straightforward. No Problems at all!!!

IMG_12156_resize.JPG

IMG_12157_resize.JPG

Be careful with the screws, are not the same: the upper left is shorter!!! In case of mistake the second gear is blocked...

IMG_12159_resize.JPG

Check if the body fits: OK

Oil on the rotor axle

Brushes in place

Check with 16V DC both directions: OK

Time for the next step: Decoder Installation

Thanks

Next step: Decoder Instalation

I will use a 21pin base plate (there is enough space).
The think is that latter I can put in a speaker, plug in a sound decoder, and the Loco can have sound easily without any modification. There is space in the body for a small speaker Märklin or ESU.
At the moment I will use a 60942 decoder.

The functions will be:
f0: Front-rear lights
f1: Smoke generator
f2: Valve Gear Light
f5: Cabin Light

First I attached the base with a screw were the reversing unit was.

IMG_12162_resize.JPG

IMG_12165_resize.JPG

IMG_12189_resize.JPG

I made a small PCB and I used SMD resistors for the LEDs of the body (front, cabin, valve gear), the resistor for the rear light will be in the Tender.
(The photo is of an identical PCB but with different resistor values used in another conversion)

IMG_12179_resize.JPG

With a drop of warm glue I fixed the plate in the back of the decoder plastic base.
Soldering of the wires..

IMG_12687_resize.JPG

The resistor values are: 1kΩ for front LED and 2kΩ for the cabin and valve gear LEDs.
Can be different according to the type of LEDs and the brightness that we want.

IMG_12686_resize.JPG

For the Front light I used a bi-pin bulb holder E604180, inserted - but isolated - in the old bulb holder. This holder has electrical contact with the smoke generator contact. So the Aux1 br/red wire soldered on this for the f1.

A 5mm WW LED inserted in the E604180 (be careful with the polarity: gray wire is the cathode).

IMG_12692_resize.JPG

IMG_12690_resize.JPG

The cabin light and the valve gear lights are SMD LEDs WW (AUX3 and AUX2)

Finishing the wiring of the motor

IMG_12693_resize.JPG

Decoder in place

IMG_12694_resize.JPG

Everything is working properly

Next step the rear lights not done yet

Hi to all

The conversion of the 3048.5 that started some months ago finished yesterday.....

The Final step is the Rear lights on the tender

First a couple of photos of the Cabin LED:

IMG_13093_resize.JPG

IMG_13095_resize.JPG

The tender in the locos of these years is not permanently attached to the Loco. I decide to keep this so I make a 2 pole connection from SIL. The female on the Loco:

IMG_13091_resize.JPG

I drill carefully two 3mm diam holes where the faux lights are on the tender.

Inside I had put 3mm WW LEDs connected in series

IMG_13099_resize.JPG

IMG_13105_resize.JPG

A 47kΩ 1/4 W resistor soldered in series with the LEDs on the Yellow wire (-).
IMG_13109_resize.JPG

The Loco with the Body on. With the black painted magnet looks fine!!!

IMG_13114_resize.JPG

The Tender is connected

IMG_13115_resize.JPG

IMG_13116_resize.JPG

That's it.

In case that I like sound the only think that I have to do is to change the decoder and connect a speaker.

Thanks

Costas

Nice work Costas!

I had made the mistake of buying a 60944 kit for my conversion before I found out that it needed this special kit, so instead I used a Hamo magnet with a Lokpilot decoder that I happened to have in stock.

I made no provision for extra lights on mine, but this could be a future addition as I have the extra functions available on the decoder. I will no doubt use some of your ideas to help me out!

Thanks for sharing this project.

OLD TOPIC UP - I have read the conversions made by Dale Schulz and KTiolas.
The old motor shield, in one case, does not have the chokes in the other, new motor shield, has the chokes.
I'm using the ESU decoder conversion and I have never used chickes in 20+ years of doing this.

I'm also going to use the digital lamp holder for the only front light.
This means that I will have the F1 cable available to control the smoke unit, if I manage to find wherever I put it.

In case I wanted to use the realy mentiond Dale Schulz's post where do I find it or another similar ?

Is this ok ?
Thank you
