![]() ![]() ![]() ![]() The original gear had been pushed all the way in but I only got the new gear flush with the edge of the pin. With the arms out, you can completely remove the top to easily replace the gear. Left them sticking in one side: just enough to take the arms out. So, for anyone else needing to repair this toy - I used a small punch tool to push the pins out of the arms but not totally out. The only thing that worried me was removing those pins so I could take out the arms and remove the top for full access to the gear. I found your post through a google search, ordered the gear from NWSL and fixed it myself in less than 30 minutes. The motor ran but the toy did not rotate. Thank you so much for this information! I bought a Dumbo monorail accessory from eBay and it arrived not working. Layout also includes a customized Haunted Mansion that I repainted to match the colors of the WDW one and installed an audio unit in it that plays a complete recording of the stretching room narration. The crown jewel of that setup is a modified switching station that uses servos which are also remote controlled to send the monorials (two simultaneously running) onto one of three separate track loops (one for each of the three hotels, the Grand Floridian, Contemporary and Polynesian. I have monorail activator units for all three, which makes for a lot of action when my Christmas WDW set up (featuring modified monorails that have wireless direction and speed controls) goes up. Have never had any problems with my Astro Orbiter or Teacup rides. I got a Dumbo off of Ebay, which did require repair which was somewhat labor intensive (had to dismantle pretty much the entire thing to get to the drive mechanism, which works fine once you do some modifications to better secure the motor so it doesn't have gear slippage). Mod 0.6 x 8T SG x 6.04mm OD x 5.0mm face x 2.0mm bore, delrin *press out the pins and remove the four arms Once apart we can remove the old gear (which is most likely cracked) and replace it with the new one.Īs far as I know this also applies to Astro Orbiter Tea Cups and maybe other monorail playset rides. The supplier is Northwest Short Line (NWSL, now owned by OsoRail), the part number is 2921-6, $9.95.ĭumbo is kind of tricky to take apart and although someone claims he is the *only* one who can do it the fact is most good modelers will figure it out*. I should have known they would either have the gear or would make them since that is their specialty. It also seems that due to the age of these toys some gears are broken even when new in the box! The gear is an odd size and difficult to find but after a long search I found the gear was available from a model railroad parts supplier I have bought from for years. It seems most of the Dumbo toy rides have a broken gear, the symptoms are: motor runs but the ride does not move. ![]()
