    Repairing 12v train motor

    Have you checked this?

    Repairing 12v train motor

    I bet you did not disassemble the engine this much. After my last post, I discovered there were two types of housing (symmetric to each other). So it is possible that if you put the motor of one type on the housing of the other type, your motor turns on the opposite direction. I have to do more research and experiments on this but will come back to this topic with more details and some photos.

    12v train green tray differences

    Evan, I already answered Jaesroe on facebook, but whenever I get some time, I will give a complete description of inner trays concerning trains 7720, 7730, 7740 and 7750.
  4. Hi guys, Long time no see! :-) I have opened a 12v train motor and changed the wheels since the gears were broken. I glued the motor and now, it works perfectly well except that it runs on the opposite direction comparing the other motors. Do you know what is the cause and how I can fix it? My guess is that the gears or generally speaking, the 12v motors are not necessary compatible with each other, but I may be wrong.

    A new Lego store opened!!!!!

    Anybody knows if this website is still open and active? I tried to open an account but it didn't work and I didn't receive any confirmation email to open and submit an order.
  6. Last year, I missed one auction of boxed train 7710 from Calgary, Canada. The Canadian Ebay being almost useless for buying and finding used Lego, it is even harder to see a vintage train like 7710 with box again. However, I found the photos of that auction (after one hour googling) Here there are: This train was never sold in USA, but was sold in Canada at least since 1981, as we can see the catalog of 1981 in this photo. On north of America, no service pack (for trains at leas) was ever sold in (early) 80s so the service pack 1134 blue battery wagon of 7720 was not available. In these photos, we can see one extra informative photo, in which it says "Four Lego drive wheels have been included in this set. This should be used with the #107 motor set if you wish to motorize your Lego train." In all European catalogs, it was mentioned that one can motorize 7710 using a 12v motor from 7865 and 4.5v motor from 107. See page 12 of this or page 27: This paper has been only seen in this auction from Canada. But why the Canadian 7710 got four extra wheels with black rims below as we know that the motor set 107 had these four wheels anyway? I don't know if it was the Canadian Samsonite who included these extra wheels and the paper? We know that Samsonite had its own way of packaging. The Canadian sets had different boxes than those of elsewhere. Can we say that TLG wanted to include four extra train wheels anyway, as the train rims could perish? (as other 12v sets had extra train rims) Not convincing, because they even made an effort to include an extra informative paper. The answer is simple but interesting: The Canadian 107 didn't have these drive wheels but different ones. The image of the box show a different wheel. One image on the back of the box is also different. See
  7. I am busy but will post the solution soon. (by the way, I have already give you the answer in a private message but I know you want other know the answer too) Concerning the last part of your question " and Why?", I found out the answer yesterday.
  8. OMG! How did you find these?! I am collecting Danish boxes of trains 7710, 7715,... . It is so hard for me to find and buy them from where I am: Canada.
  9. No, I don't. The wheels of each train has been checked since many years ago. Many people bought and sold this train on Bricklink or used the inventories as reference. They wouldn't have missed such an important part of a set, would they? My sincere apologies that you are no interested in this post. I thought it would be interesting for some people. I am referring to something specific. To give a hint, the discussion for this post is already referring to the answer. Back in 80s, TLG sold these sets in certain countires. For example, no 12v train was sold outside Europe (unless by private retailers). Also, for each country, a variation of box were used. At that time, nobody knew about these differences but the managers of TLG. It is now with the help of internet that we are discovering so many odd things. It looks like it never ends. If you are interested in this, you might be interested in the answer of my quiz. I don't know your country (or the country you were used to live in 80s) but what sets did you have in your childhood? If you are referring to the big red wheels of black train 7750, then I am not sure they exists also in black. Nonce in black is for sale on BL. Do you have a photo of them?
  10. Hi :-) I am not talking about those variation of wheels. Those are missing from many sets, including 7735, 7745, 7823, 7816, 7817, 7839,...(what else?!) This variation does not yet added to the catalog of Bricklink or any other website. I know that TLG used red pins instead of black only in (about) 1986. I don't know exactly why. There are rumors that TLG made a mistake or had too many red pins at that time and wanted to get rid of them. Anyway, since 1986, the only train using red wheels was 7715 coming with seven red wheel bricks so coming with 14 red central pins but maybe this single set was not enough to use all extra red pins they had in 1986 and they got too much space in their stock rooms?! :-) But no, this is not the answer. Something is missing from one single set (as far as I know: only one set). :-) ;-)
  11. Hey guys, Long time no see! :-) I came back to Eurobrick with a new quiz: What train set from 80s misses (train) wheel(s) in its inventory? (can be as regular or alternate) Let''s restrict answer to 7710, 7715,....7760, 7810, 7813, ...,7821 The missing wheel already exists in the catalog of bricklink but it is not added to one particular set yet. You can check bricklink for the inventory of these sets, but other sources are ok too.
  12. The whole story: I bought in September a boxed copy of 7745. The parts were in good condition. I stored my Lego collection in last December. Then I opened 7745 in February and checked all parts carefully. I noticed one wire was different than the inventory. I had not seen that wire before so I did my own research on items for sale on Ebay,... At the same time, I was doing investigation for variations of other parts such as hinges (solid or hollow stud), special powering conducting rail 2731a or 2731b or interference-free 3241c,.... I contacted a seller on Ebay of UK and asked about production date of her motor: Her answer: "I have around 5 motors so I have put what ever one you want in. I will check and make sure it's the correct type or change it if you require." That was disappointing as her train would not be original at all. She had too many sets and parts and she might even be a professional seller. However I contacted her again about two weeks later as her train was still for sale, and asked her to send me a photo of the wire that was plugged into the motor. Her response: "Hi, the motor and cables are as per the instruction booklet. I struggle to find what the original parts are as the instruction booklet shows differences to online inventories. I think there was an early release and a later release of this set. Or it may have varied in countries. Please see photos of the book showing identical motor and cables. I have around 7 of these motors in the various sets/ spares I have. Let me know if I can advise anymore. Book is dated 1985. Manual also shows diffused lamps but these are clear lens." That was SOOOO disappointing. I dislike it when the seller gives a different answer than what I asked for. I needed a photo of her own set not a copy of her instructions that is anyway available online. However, I clicked on the photo. It was at this moment that my eyes got fixed and my mouth opened for few minutes. I gazed at the photo of her instructions for some time.... After the initial shock, I got up to check my three copies of instructions of 7745. I found out that there were two versions. I checked all pages. The only difference comes in that wire, both on the main model and on the alternative one: The first instructions comes with the wire 765c28 (together with three wires 766c28). Its Id number is 120419. It was released in 1985. The second instructions comes with the wire 2776c28. This one did not exist on bricklink! I don't know how sellers sold their wire and why nobody had not added it to the database! I recently added it and since then, two sellers have added it to their inventory. :-) The Id of the second version is 120620 and it was used since very early 1986 until the end of release of this set in 1990.
  13. @Carrera124 You wrote here what your favorite train is. I didn't know it went out of race!
  14. I was hoping that someone could point to various instructions for a different set that what I intended (But Carrera124 pointed to slight difference in instructions of 7735). It seems there is only one correct answer. The answer is the favorite 12v train of Christian "Carrera124" :-)
  15. Only three instructions left: 7740, 7735 and 7745 :-)
