Hallo from Greece
« am: 17 Juni 2012, 20:43:46 »

Hi everyone. I am Stelios from Greece. Your forum is a treasure of literature, infos and knowledge about BMW classics. Congratulations!
I own a BMW R51/3 ( the one in the fotos bellow) which is  finished restored and I would apriciate any infos or tips from you who are more expirienced than me!
Here are some questions for you.

1) What kind and how much oil I should put in my fully restored front fork with new fork dumpers (bought from Stemler).

2) What kind and how much engine oil shoul I use. I still have tha original oil pan.Note the higher weather temperatures in Greece. Engine number is 525365

3) What kind and how much oil i should use in the transmission and in the gearbox.

4) Which spark plugs would you recomend .I still use the original 6volt magneto and ignition system. I hear that NGK Iridium BR8HIX is recomended for better  results. Do you think is a good idea or should I avoid putting them.

I would also apriciate any info form my bike you can give me by the engine number (525365).

Any answers coming out of your knoledge and expirience are welcome!

Thank you in advance.
Best regards
Stelios

OK!
My English is not so good either, and I am dissapointed of myself that I didn't learn German when I was younger. Both my parents speak German very good, and I was born in Frankfurt, but came back to Greece when I was a baby. Anyway thanks for the responce!

Hallo to Greece ;D
1.(+2) do you know which dampers you have in your fork? there are 2 types..."modern" with konical "dampers"....they need forkoil....the old ones: motoroil
Forkoil....you will have to try out...SAE 15 is a good choice to start
Motoroil....the same as in your engine: SAE 40 (SAE 30 you don't need, is for colder times...I hope you don't need ist ;D
2. see above
3.Fortransmission : best is gear oil SAE 90 ...attention not younger than GL3....if not  obtainable...take motoroil SAE40
4. Sparkplugs: the "R" in your NGL means "entstört"....not good...try to get plugs without "R"...or normal Bosch W4AC...or if you ride "hot"...W3AC....you will try out...if you drive more calmly...the W3 will  get black...then take a W4....if this also gets black...drive faster or (not good choice) tkae W5AC....or W6AC

5. " would also apriciate any info form my bike you can give me by the engine number (525365)."

I don't understand what you want?

Greetings
Rolf

Hallo again.
Thank you Ralf51 and rolf.
I really dont know what dumpers Stemler send me, I remember that I payed them 170 euro each one. You  can see them in the picture bellow. If it helps I can make a foto of my old ones That I keep in the basement and post it next time (they are the same type).  So far I use 10 hydravlic oil and I find it very very soft.
In the engine (which is with all new pistons bearings and sealrings, the rest parts were in very good condition) I use SAE 40. And for the gearbox and transmission I use SAE 90. I just ask you because I always like to know more opinions and I like to talk about and learn more things about the bike!
For sure I will change the fork oil with the thicker one.  Today the temperature went up to 38 degrees so you can imagine it is not good for oils, but generally I avoid riding the bike in these temperatures.


Spark plugs I use NGK BR8HS so far, they are ok, I was just wondering if with IRIDIUM spark plugs I have a better and more smooth running of the engine, thats all. But I will take your opinion for using  Bosch W5AC  or W6AC.

Now about infos according to the engine number, I mean if for example i could know which month and from which factory exactly it came out and if possible
( very difficult , i know )which was the first owner before my father bought it in Frankfurt in the mid sixties.
Thanks again , I will keep posting my expiriences with the old R51/3 and share opinions and discussions with you!

Hallo Stelios,
this are the "old" damper type....so use Motoroil....SAE 30 or 40...you have to try out what you like more.
Bosch or NGK....you can take what you want...I use NGK....but I only knew the Bosch specification (W4AC etc.)...for NGK you must search for yoursdelf at the internet....also for Iridium, they should be better than the normal bougies....try ist out...if you are happy with them....use them! but without R.... if possible.
For your last question...write an email to "mobile Tradition"....they will have all answers for you.

Hallo !
Thank you all for your answers.
I have send email to both INFO.GROUPARCHIV@BMWGROUP.COM and mobile Tradition and waiting for infos.
Today i am going to change the oil in the fork. I bought MOBIL SAE 30. I let you know!

P.S. To rolf: can you please be more spasific about the R in the spark plugs, and the reason I should avoid it, because I have not a good knowledge of these things?

"R" is for resistance....if you have also (!) a normal spark-plug-cup/cap (?Kerzenstecker?)...they have also (!!) resistance....so you have 2 resistance....each of them weakend the sparks (make it less powerful)....why resistance....it is for that the sparks of the bougir doesn't disturb radios (especially Cop-radio-transmitters ;D).

oha...das war mal wieder pidgin english vom feinsten.

OK. I use these ones, (my mechanic which by the way is German) doesn't like them. He says , on a German machine I should use German stuff  ;D.

 

NGK LB05F
Spark Plug Resistor Cover


High quality Ceramic Resistor - enhances protection against RFI
High Performance
Maximum heat resistance
Miximum voltage resistance
Waterproof
Long Durability


So I avoid the R , correct?

Today i changed the fork oil. Later i will have a test drive and write you the news.

High quality Ceramic Resistor ....you don't avoid the resistor, .....by the way ...I like the NGK....small, durable and cheap and the have have noot this ugly metalcover like the Bosch....this NGK has an resistor of 5 KOhm (=5000 Ohm)....you can measure it!
If you like you can grind the NGK away....and...if you like....put a BMW sign on it.

Good idea rolf, easy to do and nice when it is done!
By the way  the behavior of the fork  with the SAE30 oil in it is much better than before. Not perfect, but, we are talking about 1951 tecnology (maybe even earlier designed). The bad thing is that the temperature here is very very high this year  (38 to 40 ) every day so i cannot enjoy riding the bike alot, I dont want to give it a hard time. A little bit in the morning and a little bit in the evening. Not this evening, I have to watch football! ;)

This is the answer I got from the BMW Group archives. Not much but, at least i know when I can celebrate her birthday!!!


Dear Mr Vasilakis,

Thank you for your email.

The BMW R 51/3 VIN 525365 was manufactured on September 26th, 1951 in the BMW factory in Munich and delivered the same day to the BMW dealer Neumann in Herne (Germany).

Unfortunately there aren't any information about what happened with the bike after its delivery. So we don't know the owners.

We hope this information is helpful for you.

Yours sincerely,

Christina Hartung
