Question
I have a Mills Imp trade stimulator. The reels on it spin but only spin one quick rotation then has a sudden stop. Do I need a new pump or can I just lube this pump up real good and maybe the reel gears also. I have totally restored this and it looks awesome but I need to get the reels spinning properly. Thanks for any help you can give.  Steve

Answer
Hi Steve,

One quick rotation and then the machine stops the reels too early, right. It is indexing the reels way to fast. When you pull the handle on a machine you are creating energy by stretching all the springs, once the machine kicks the reel off it would stop right away without a way to let that stored energy play out slowly and some what controlled. That is the pumps job on trade stimulator's that use pumps, and on a slot machine it uses a clock with a fan to do the same thing. So, your pump is not holding the energy back long enough and this could be a bad seal, dry seal, and most likely it needs oil to help the piston seal inside the pump seal better. On the back of the pump you should see a screw and a locking nut, look just above it on the pumps end and you will see a tiny hole. As you turn the screw in you close the vent hole, screw it out and you open it allowing the presser inside to go out faster. What you need to do is add some oil to the bump by taking that screw and nut out, and shoot a little oil into the pump. For pumps I use a leather neatsfoot oil because this oil is made for leather, and regular oil is not good for leather. Most handle pumps on slot machines uses a leather seal inside the pump. I am not sure if trade stimulator's use a leather seal or something else but to be safe, I would use a leather oil like neatsfoot oil. After you get some oil into the pump, play it once or twice without the screw so the excess oil can escape if needed. Then put your screw and locknut back in and play it. If it stops to fast start turning that screw in until you get it to hold back the spinning of the reel to the point that the machine stops the reels just before they stop on their own, and you will have it adjusted right. If after adding oil and trying to adjust the pump and you can't make a difference at all, then you might need a new pump or figure a way to get it open so you can rebuild it if possible. I hope this helps and I would like to know if you are able to get it to work right.

Thank You

Expertise

I am an expert on old coin operated machines, slot machines, trade stimulator's, jukeboxes, old arcade machines, etc. I have been identifying these for people who respond to my web site listed below, for a few years now. In almost all cases I am able to tell them about their old coin operated machines, the year, the value, and other general information about their machines. I do not know much about soda vending machines, coin banks, or scales, but I will try to help you with these if I can. Please email photo's to: info@coinslots.com My web site is at: http://www.coinslots.com

Experience

I bought my first slot machine, a .50 Cent Mills Black Cherry in 1969 and have been hooked from that time, I still have that Slot machine! Before that I found a open barrel full of old scraped jukebox wall boxes behind a restaurant, I wanted them all but never took a one of them. Anything that took a coin drove me nuts!

Organizations
C.O.C.A. and other slot and coin operated machine groups, associations, groups, and clubs.

Publications
Many, the Coinslot magazine, always juken, Coin Slot Journal, Slot Box Collector, and others that I don’t remember at this time.

Education/Credentials
Graduated from Ballard High School in 1969, went to Edison Technical Collage for a couple of years taking welding and metal fabrication, tig, mig, heliarc, also arc and gas welding and fabrication. Then Apprenticed under a slot machine technician who worked in the slot machine industry Reno Nevada, and set up bar poker progressive machines in the casino's, and repaired machine and did the repairs on slot machine circuit boards there. He also was involved in the 2 hand dealer's market and bought and sold machines at the casinos auctions for the secondary market, which includes selling used machine overseas. I learned a ton from this man; he always had the correct answers and took the time to teach me the business. My interest and knowledge in other and older coin operated machine is for the most part, self-taught. It's been my passion from back in 1968 and before, my thirst for knowledge about these machines has kept me more interested over the years, and keeps me searching for more information even today. I have meet and talked to book authors on these machines, attended hundreds of coin operated shows and auctions, and I stay with that to this very day.

Awards and Honors
Take a look at my allexperts rating, and my guest book, links to these are at http://www.coinslots.com Also you can check my 100 percent rating on ebay, as I have been there with ebay from their day one, I am user coinslots at ebay. My other awards come from the very people that I deal with, I always make them happy, no matter what it takes, but they always are happy anyway as the countless thank you letters testify to me, so I know I am doing right, and the best I can. I have found so many hard to find parts for people, I hunt them down and don't stop until I find what is needed to get that customers machine running again and back to life, that is my main goal.
