Funnily enough I did sell one of my bandits a couple of years back through ebay. The chap that bought it ran his own travelling penny arcade. I don't know if I'd bother selling on there now as you seem to need a gaming licence. Although having said that, I never had one when I sold mine, but maybe they're stricter these days at applying the rules.

Regarding the Aristocrat; last time I played it (which was many years ago) the reels weren't spinning at all. The clock seemed to be working okay but the reels weren't engaging and disengaging. Having tried it today, the whole mech seems to have seized.

I will get stuck into some thorough cleaning over the next week or so and will no doubt be back on here for some much needed advice!

Cheers,
Adam

So true BP what you say about what some people say on Ebay, to try and flog a machine. "Unable to test" is another one when in the case of mpu base machines, all they have to do is plug in and switch it on. There is one on at the minute for an MPU4 psu, and he says "works fine just needs new fuses" Doesn't inspire confidence.

Well done on sorting your escalator out Adam. Sounds like a tough job you have done well with there.

Thanks Alex, I am a complete novice, so I was chuffed that I was able to get it sorted.
The latest issue is that it's not paying out any more. I think by messing around with the payout levers, I might have put it out of sync. I can get it to pay out, but I have to pull the levers back from underneath the mech. The coin slides then spring open and the money drops out. When I put the mech back in, it will pay out for the first time, but then fails to pay out afterwards. The only solution is to remove the mech, pull the spring levers back and then it's back to square one again.

Is there a simple way of resetting the payout, without having to strip it all down?

Some photos:

I'm hoping that someone may be able to look at the photos and spot something that's glaringly obvious.

I've referred to the attached and whilst it's been a great help, it's not helped me to diagnose this particular problem:

The photos are not really much help as they don't cover the bits that might be wrong,
As it was paying OK, we can assume that all springs (vertical finger and rear horizontal finger springs) are OK. (Check anyway, in case one took flight during the repairs). Best way is if we all run you through different operations and eliminate them from the problem, so first, the most basic test of all... run the machine, in the case, and listen for the last two clicks at the end of the cycle. These are the vertical fingers falling against the payout plate on the reels and the slide brake releasing the slides to pay if needed. If one of these is not sounding, then move on to the following: Take the mech from the case and operate it through the wind up part of the cycle, stopping just before it falls into the run down. Now look to see if the slide brake has dropped behind all the slides, holding them back while the mech unwinds. Complete the cycle and see if the slides fall back immediately. If they do, there is your problem. They should fall back as the very last operation of the cycle. This brake is operated by the clock and moves in from the left as you look at the mech from the front. If the adjustments are out, the slides don't go far enough forward to allow the brake to get behind them and they fall back way too soon, stopping the horizontal fingers from moving back if there is a winner.

Sorry about the photos, to be honest I wasn't really sure what to take photos of so just took some random ones in the hope that someone might be able to spot the problem.

Anyway thanks very much for your advice and I'll try running through all the steps you've suggested and will let you know how I get on.

Thanks again for the response.

Cheers,
Adam

I took your advice and ran all the tests. I was then able to locate what I think must be the slide brake (as pictured) and concluded that the part that holds the slides forward had jumped out. I was able to manually push all the slides forward, which enabled the brake to drop back down into place. I've run it a couple of times and all seems fine now with the payouts.

Next job is to build a stand for it so that it can take pride of place in our conservatory!

Thanks again for your help coppinpr.

Cheers,
Adam

Even deliberately trying to foul it up, in order to be able to spring into action with your Swiss Army Knife will be a series of non events.
You've also discovered the next hint. Don't allow a sudden gust of adverse gravity to have affect upon the ordinal positioning of the monetary discs within the horizontal motive dispensers.

Aristocrat Grosvenor eh?
I suggest the first thing you do is smear everything in grease before turning it upside down and giving it a damn fine shaking (Not Metric of course)
I can report that the Aristocrat is now in full working order! I took the reels out (after reading through one of Coppinpr's old posts on removing reels on an Aristocrat), sprayed the mech liberally with brake disc cleaner (well the whole can actually!), gave it a good scrub with a toothbrush and allowed it to dry. I then sprayed liberally with 3 in 1 oil, replaced the reels and what do you know, it works perfectly! Quite amazing considering it's lived in my shed for the last few years and prior to that spent several years in a cold garage! These machines were certainly built to stand the test of time!!

There you go, you've rapidly become one of our most experienced machine fettlers.
Us old timers can now go and sit under a tree for the rest of the Summer and leave the helping out to you now.

I thought we had to share a can?? Anyway Leetch Polish beer is better. We can light a fire in the park and leave the bottles spread all over the place. If we want to be really authentic, we can smash a few in the children's playground.

I hope that 3-in-1 oil is nowhere near the payout slides :tut

Not tried Leetch yet, I do like a drop of Tskie though, so I'll have to give Leech a try.

Re the coin slides, I'm guessing that 3-in-1 oil in coin slides isn't a good thing? I'm afraid that in my naivety I may have sprayed the coin slides as well. Does this mean that I'll have to strip them down now and de-grease them?

Adam

Rule number one of Slot Restoration is ... Never mention Slot Restoration. Rule number two is never oil anything that a coin comes into contact with.
If the slides don't .... errrr .... umm ... well .. slide, then slacken off the pillar screws a bit and if you feel the need to lubricate stuff then use graphite powder. You can get it from locksmiths.

Just like fight club eh!

I use graphite powder on the nut of my guitars, I just grind down a pencil lead and use the powder from the pencil. I've been told that it's graphite, so I'm assuming I can also use this on the slides?

If I leave it as is and don't clean the 3-in1 oil off the coin slides then will this lead to further problems in the future?

Thanks,
Adam

The oil attracts dirt and causes the slides to stick against each other, so in the long run it would be best to remove and degrease them.

It's preferable to apply oil only where needed (cogs, bearings etc.), again because it will bind with dust resulting in a mucky mech. :sick:
Also, too much oil around the clock will splatter and contaminate the reels strips.

Thanks Badpenny. I think next time I'll use the 3-in-1 oil from the can rather than the spay version, as then I can use it more sparingly! Looks like a stripping down and cleaning of the coin slide is next job on the to do list!!

Looks good, although as you said the inner part of a pencil is graphite if you can be bothered.

The first clue that you've allowed oil to contaminate is if the coins paid out are dripping.

For £3.50 inc. delivery I think it makes sense and will save me grinding down loads of pencils! A 50g bottle should last me a while as well. Incidentally, I see that WD40 now do what they call a "dry" spray. It uses PTFE, so I wonder if this would be any good a general lubricant for the mech and coin slides?

If not then I'll stick with 3-in-1 oil and graphite powder.

These machines took a hammering all season and only got a serious looking at the end of it.
Once you've cleaned out the accumulation of dried grease, everything should be fine for years with the amount of use you're likely to give it.

I'd look carefully at the ingredients of anything you spray, I'm not aware of a new WD 40 product.
The original isn't the best to use as it's based on fish oil. Anything that contains organic matter is going to change its consistency with time.

The graphite is useful for many things, and being black you're not likely to get confused and snort it.

I've just looked at The WD 40 website.
The price of this new product is only "awfully horrendous" but most disappointing is their answer to the question .......
"How is the WD-40 Specialist line of products different from original WD-40 Multi-Use Product?"
Their answer ......
"WD-40 Multi-Use Product was invented in 1953 with five basic functions: It Lubricates, Penetrates, Protects, Removes, and Displaces Moisture. WD-40 Specialist is a line of specialty maintenance products designed to meet specific needs of professional users."

Hmmm! If you don't want to answer the question why put it in you FAQs, pointless!

Pretty useless then when it comes to customer support! I think I'll steer well clear of it and stick to the tried and tested products.
