Hey all. I thought it was time for a long overdue update on this. I've been busy with work and family so have been limited with time to work on it. After looking at all the IC's under the microscope, pretty much all were showing some serious corrosion on the legs, along with some of the caps too. I eneded up replacing all caps and socketing all the IC's on the motherboard. The only ones i didn't replace were the RAM and the CPU itself. I also replaced all the transistors for the three motors and numerous ones for the lights as well, along with sorting out the sound issues by replacing the trimmer pot that controls it. After doing all that, i still had a problem with the Number 2 stepper motor binding up! Luckily i managed to find a replacement on ebay though, fitted it and it all worked ok. As you can see I still have a few lights to sort out, along with some cosmetic repairs to the cabinet. Annoying the stepper motor for reel 1 has now started to bind up in a similar way to the one I replaced on reel 2! The chances of finding another replacement being fairly low, I decided to strip the one that I had removed previously. I know a lot of people say they shouldn't be opened as they are difficult to assemble again, but I've managed to get it open and stripped it down pretty easily. I removed both the front and rear bearings and soaked them overnight in some oil in the hope that some of it would get inside. Unfortunately they seem pretty well sealed, and any effect is only very short-term. However I've managed to source some new ones, so as soon as they turn up i will fit them and rebuild the motor. I'll film it as I go and will post a video up here of it.

Just a quick warning make sure you get the polarisation of IC 33 & 34 correct as they are opposite to each other. It's very easy to remove both and then forget and put them facing the same way. (I've done it) Depending on the MOD there may not be any markings on the board!

Great work and glad you are nearly there .yep had the same thing with those motor s as well.jist a bit of wd or contact spray is the best you can do for them

Nice work, just to say I had the same problem with these stepper motors! I too stripped and replaced both bearings on all 3 steppers but they never worked properly! I think when made they have shims of diffrent sizes to whatever tolerence is needed Ronnie

No worries, they are difficult to spot. Just under IC8.

Top man barrie great job by the looks of it .

Right length from top fruit to bottom and they are all nudged to line up so it should be spot on........

So then, I re sized all these today. All matches up. No choice now but to send them off to print and check.... Heres a proof, looks like ive nailed it. Hope so!
