Hi All, It's been awhile since my last post, so I thought it was time I made another. I have been in receipt of a BB12VB-RED recently! Ahem, probably more like a year or so ago. As you can see from the photos, one of the pickups is very damaged… Another Eurobrick member, Alainneke, had already kindly made some replacements out of brass… I had sent him the diagrams of the pickups in AutoCAD, and extremely excellent reproductions were sent as a test in return. At the time I’d only opened my 'teenaged' black motor, as seen in photos, and the new brass pickup studs were supposed to be destined for it… The RED 12V motor is very, very rare, I have held back on using the replacement pickups until now… I am glad I have waited though, my apologies Alainneke! After reading VGO’s suggestion in post http://www.eurobrick...pic=50345&st=25, post #28, I tried the idea out on a black motor and it moved during the operation and I snapped a tab off the end, see pic. So I decided to build a jig out of Lego to hold the motor. The top part of my jig is real Lego, while the bottom is entirely made of Fako(Fake Lego) due to my needing to augment some of the pieces to fit the underside of the motor and wheels. I used MEK(Methyl-Ethyl-Ketone) to ‘weld’ the pieces together, along with some small strips of a smooth(no embossed numbers) credit type card, see pics. Okay, My advice is that you try and run a razor blade around the circumference of the bottom of the motor, hopefully using a ‘jig’ like shown. I do mean “Razor blade” as a “Stanley” knife blade will do the damage that I have shown in my earlier openings, try a ‘BIC single blade’… Making and using a ‘BIC’ single razor blade… I used the razor whilst the motor was in the top part of the jig. Once in the jig, use a 2.5mm rod/nail and hammer in both power plug holes, to gently persuade the bottom to come loose on either side. Seat partially opened motor on the ‘bottom’ part of the jig, and use the remainder of the credit/shopping card to gently hammer down on the wheel axle to pry the last of the plastic welds apart. The motor is now broken open… Here are some pics of the open casing with the old and new pickups, I will update the post after I have cleaned up the motor parts. If for whatever reason you need to take a wheel off, I.e. for cleaning excessive hair/crud in sleeve bearing, then you start by removing the cir-clip next to the sleeve bearing. Move bearing nearer to gear cog, then gently pries the cylindrical spring clip out of the wheel in the same area as the hole in the wheel. When you're cleaning the parts inside, be careful with the metal part 'A'. There are two small hardened steel discs that sit either end of the spindle, only the dirty grease is holding them in.... Now it's time for reassembly and re-greasing...
