Duo Mat payout problem

Postby arrgee » Fri Jan 22, 2021 5:06 pm

This DM is refusing to payout on a win, on closer inspection there appears to be a 3D coin trapped between the bottom payout slide and the payout guide/base support - it is stuck fast and my concern is that if any force is applied in levering out the coin the alloy may crack.
Any ideas on how to release this little blighter?
I have also noticed that there is a collar surrounding the vertical payout rod which is loose and rotates (as indicated in second pic with wooden pointer) the collar has a small bolt that is loose, I assume this should be tight. The rod can be freely moved up and down by about 2 to 3mm.
Any advice and help would be gratefully received.

I think the only safe way would be to dismantle the coin slides. I can imagine that you are trying to avoid this but, as you say, prising it out runs the risk of breaking the slides. It also gives you the opportunity to clean the slides and work out why the coin jammed in the first place. BTW are there any 2D coins around? :lol:

Yes, set screws should always be tight. It seems to be to adjust the spring compression, although someone else might know otherwise.

You've got to take down the slide bundle, no other choice.
That bottom slide looks as if it has a crazed surface already.

BP :cool:

Just pop the mech out of the case and remove the coin slide unit. It really does only take 10 mins or so providing the bolts aren’t seized.

Yes noticed that bp when I looked at the photo, but the bottom slide looks to be a brass colour and certainly not the usual alloy
Thought a strip down might be the case - never done this before so rather apprehensive.

That is the brass masterslide and the crazing is perfectly normal, they all do that.....

For a coin to get under this suggests there is another issue as should not happen, especially if as thick as a 3D. Are all slides intact and top cover properly screwed down

I agree. The only way I can see this happening is if one of the slides has broken or if the screws in each corner are lose/missing. Unless of course someone has been at it in the past and resassembled it incorrectly or with the wrong parts.

ok...... so by looking at the mech it appears that following disconnection of the crank lower linkage, the main body can be removed, it also looks like the coin acceptor mech can be left in situ, is this correct?

Thanks for the advice

Yes, undo three nuts, the linkage to handle and lift away.

Will give access to pay system.

These really are easy to work on, main advice though, if you do take apart the payout parts, the bottom slide carrier and top cover are real delicate and I have seen or had main disintegrate when taking apart ad worse still over tightening. Be gentle with these. You should be able to see what is happening on the slide front. How many slides do you have and what coinage
