Vintagebricker Posted January 30, 2015 Posted January 30, 2015 Hi, my name is Vintagebricker. I am new to using a Forum, so please excuse any errors etc. I have recently acquired an original 8480 Shuttle set. I have almost completed the assembly but find that the control knobs at the rear do not function as intended. Located on the shaft are 2 "comb wheels", 1 of which should reach down between the 2 switches on the top of the battery box to facilitate on/off/reverse operations, but the arm is too short (by approx. 8mms). I have re-built this section several times but alas with the same result. I note, with some frustration, that nobody else has posted this issue - anywhere! Many people have commented that this set is one of the best that Lego have ever produced. I would love to be able to concur with them. Can anyone tell me where I may be going wrong? Thanks Quote
Peppermint_M Posted January 30, 2015 Posted January 30, 2015 While I can't help with the issue (Do you have photographs of the problem?) I think if I move this into Technic you should get more help. One thing I can suggest, is the axle the right length? If the set is second hand sometimes wrong parts can be boxed in by a seller. You can look up a parts list on the instuctions or Bricklink for a more detailed/magnified list. Quote
Vintagebricker Posted January 30, 2015 Author Posted January 30, 2015 Thanks Peppermint_M and alanp. I realize that photos would've been a lot more useful but that section is in bits again at present. I was rathe hoping that someone else may have experienced the same problem and had resolved it. If my post doesn't attract a solution then I will reassemble, take photos and post. The set came from a relative who has emigrated. I checked off the inventory and all seems present and correct. I've checked out this "comb wheel" on various websites and there only appears to be one of this shape. Thanks again. Quote
JamesJT Posted January 30, 2015 Posted January 30, 2015 There are 4 possible positions for the axel to run through on those comb wheels, check you have the axel in the right hole. Quote
Vintagebricker Posted January 30, 2015 Author Posted January 30, 2015 Yeah, thanks Vassal. The top position is taken by a stud that carries the return rubber band; the axle is in the next position. Quote
Jeroen Ottens Posted January 30, 2015 Posted January 30, 2015 If I recall correctly it should use the 1st and 3rd axle hole (counting from the thin side), the 2nd and 4th are unused Quote
PiotrekJ Posted January 30, 2015 Posted January 30, 2015 Hello, I'm new here, but I'll try to help. It seems to me that you're expecting those knobs to turn on the battery box. That's not the case here, you must turn on the battery box manually and then put it inside the shuttle. By turning the knobs in both directions you change voltage polarity and you don't have to use battery box switch for this. Regards PJ Quote
Vintagebricker Posted January 30, 2015 Author Posted January 30, 2015 PJ - You are a wiz!! Many, many thanks. My wife will be soooo pleased to hear that I'll stop wittering to my self! That's just great. Quote
vliet Posted January 30, 2015 Posted January 30, 2015 I bought a 8480 a few months ago, i it didn't work as well because of bad elastic bands. I took it completely apart and rebuilt it but now even less works, not sure why, have to find out. Quote
I_Got_The_Last_Set Posted January 30, 2015 Posted January 30, 2015 I think the issue was resolved. Since you are new to Lego or Lego/Technic, I hope this link will help you and have fun. http://www.technicopedia.com/8480.html Quote
