I recently received my Metallica Premium and during game play the magnet under the hammer does not allow the ball to travel under the play field into the coffin. The machine is level so I can only assume its some kind of mechanical issue. Please see the attached video

Hard to tell but either the trough needs adjustment or if the magnet is dropping to low and wont let the ball roll down .... Either way should be an easy fix. As for the ball guide I see nothing wrong there. Take it off and bend a little if your unhappy. Remember these are mass produced and will need tuning in after you get.... I usually take a few week to get my NIB games to play butter smooth. Good luck.

Here is the underneath portion. Where do I begin to make adjustments? It might be that the magnet isn't staying down long enough to allow the ball to roll into the trough. Or if the trough needs adjustment how would I do that? That piece looks rather large

Any updates on this issue?

#6 5 years ago

I can't see it clearly but is there a switch down there that when the ball lowers it should be activated to let the magnet know to release the ball? If so see if it is responding in test mode.

#7 5 years ago

It looks like it is dropping too low. Can you adjust it up? That way the ball can fall off of the magnet & into the coffin.

#8 5 years ago

The magnet is coming up to soon and the ball is getting stuck in-between the playfield and magnet. This happens 1 out of ever ten times. Not sure why it does not happen each time.

Newpinbin,

I had my wife contact Stern (I've been working 7 days a week since April 11) and Chaz or Chad said to use some washers on the two screws where the coffin ramp is. We tried 1 washer on each side and it made a much better improvement. Instead of every single time the ball getting stuck it became way less frequent, but it still happened.

We doubled up the washers and it seems to have resolved the issue. I'm so grateful for that. I guess my only other concern is how the ball shoots out of the trough onto the play field. Sometimes the ball rattles so much it doesn't make it up the ramp in order for me to get a skill shot. Perhaps I'm pulling the plunger back too hard? It seems very inconsistent. I have also used the clear trough feature in the diagnostic and it seems to reproduce similar results with the ball losing its energy when it hits the first rail off the trough.

Where I circled in red is where I added the washers. It lowered the ramp enough to allow the ball to enter in smoothly. This picture does not have the washers installed. Didn't think about taking a picture afterwards. If you need me to I can. We used a total of 4 Fender Washers 1/8 x 3/4. I think my wife got them at Home Depot.

I had to remove a total of 4 screws in order to position the washers. The 2 right next to the ramp and the next 2 right above that allowed me slightly pull back the ramp from the wood to slide the washers in.

Aaaaah...... thats what I said right from the start. Instead of the washers im pretty sure there is an adjustment on how low the magnet drops. Im glad the washers worked but would not have been my approach.

Thank you for posting pictures. I'm going to try this. Looks simple enough, just removing screws. Did it take long to install?

#13 5 years ago

newpinbin,

It was a very quick and inexpensive fix. I remove the two screws that are circled in red. Then there are two more screws directly above them that I also remove to allow more play. I use my finger to gently pull away from the wood just enough to slide the washer in place on each side. Screw everything back down, put the play field down and then test it.

Now the trough / ramp is low enough that the ball rolls right into the coffin instead of getting wedged in the play field.

#15 5 years ago

I have my playfield up now...are you able to send me a picture of yours with the washers installed?

#16 5 years ago

newpinbin,

Sorry to get back to you so late. I'm working 7 days a week and just got home and saw your response.

#17 5 years ago

And a video, awesome! Just what I needed that answered it, thanks! Didn't want to start working on it until I knew for sure how you fixed yours.

Have you had any issues with the snake? The ball will sometimes get stuck on the lip of the snakes mouth. During the ball search it will set it free. The other issues with the snake I have been recently having is that when the ball ejects from the snakes mouth, it will spit it out into the air, causing it to bounce on the playfield. Other times, when it ejects, the ball will curve hard towards the right flipper. This just started occurring, as the ball use to always cleanly/smoothly eject and land on the left flipper.

I would say the jaw is probably too low when open. It's kind of ironic because some (including myself) had a problem where the jaw was too high when the mouth was open. I added washers to all the mounting points under the playfield to lower the mechanism. There is an adjustment screw for the jaw release latch which when adjusted can raise or lower the jaw a bit.

I think I have the correct screw shown here.

Make sure the assembly isn't loose. It' actually two different assemblies under the playfield, but linked together at one point.

Its wired that this issue is suddenly coming about.

Where does this go? Magnet control board?

This fix didn't work for me as well as several others suggested fixes by them. Stern sent a new coffin ramp off a working machine which also didn't work. My machine has done this from day one the very first ball. I've spent a lot of time on this and they actually sent me a copy of this forum thread as a fix. I'm fighting them to take the unit back as it is a lemon. The unit is level. My machine has several more millimeters of space on the right side of the coffin trap. My argument with stern is that the board is mis aligned from error in drilling. How long did this take for your machines to manifest this problem. Is this the type of service you expect from them or typical of the machines they produce? I'm hesitant to purchase another machine from them...

I took over 400 plays before this started happening to my machine. Initially the washer fix worked, but then it started happening again and again and again!!!!! This game had me so MAD that I didn't play it for over a week! I just played again 10 min. ago and the ball still gets stuck. I now hit the side of the machine when it gets stuck and it has been able to knock the ball loose. The ball also gets stuck on the lip of the snake sometimes. I really like this game and think it's the most entertaining pin made by Sten, just wish they would fix the issue.

What pitch(level is your game set at?

On the level, the bubble is right in the middle.

Have you tried replacing the balls? I had issues with mine and the balls started to magnetize. It was throwing off the timing and not rolling off the magnet core and down the subway. Maybe a different issue that what you have, but the symptoms sound identical.

Hope this helps

It started immediately for my machine

I don't see the washers installed on your machine. I had to double up on the washers in order for mine to work properly. I'm sorry you're experiencing this issue. It totally ruins the game experience.

This game had me so mad today, since the ball got stuck again. Initially I was only able to put one washer on each side, as I was having a lot of difficulty fitting two on each. Since the ball got stuck again just now, I decided to try two washers on each side despite the tight fit. I took me a while, but by removing the screws; 6 total it loosens up the ramp and allows two washers to be placed in. I have been playing the game for 15 min. now only shooting the coffin and no issues. I can see the ball is flowing much quicker into the casket and have not had any issues as of yet. It seems this may have been the issue, so as a note to all you must use TWO washers on each side as the OP has said from the beginning.

Still playing the game tonight and no coffin issues yet. At this point it seems to be fixed!

That's fantastic news newpinbin! And an inexpensive fix too!

The other thing that will help is replacing the balls.

Two biggest issues were the snake and the coffin.

Huge thanks to SomeCaliGuy! This has been driving me crazy. I was sure it had to be something within the mechanism that lowers the magnet because it seemed to be hanging up before making it into the coffin. Now after watching your video and applying your fix it appears that it is hitting the coffin trough lip and bouncing back up into the magnet/coil mech.
I added 2-1/16" washers to each side and only got 2 stuck out of 54. And, the ones that stuck were freed by the machine when it went through the clearing cycle. Much, much better than before. I will try thicker washers soon and that may fix it 100%.

It sure appears that this is an issue with the trough being misaligned where it meets the magnet/coil assembly. Moving it would require new holes so I'm thankful that this bandaid seems to fix the issue.

Stil having the issue even doing 2 washers. Anyone else got another idea of a fix??

Quoted from drgnlair:

After a TON of experimentation, I'm pretty sure that the issue is there's not a smooth transition from the magnet area into the coffin. The coffin guides begin abruptly and have a "ledge" that's the thickness of the metal of the guide. Over time that can become slightly deformed and make a nice place to stop a ball from rolling.

So I just cut two rectangles of mylar and "smoothed over" the ledge so the ball has nowhere to rest. This let the ball roll into the coffin, even if it was barely moving initially out of the magnet area. Solved the problem.

Here's a before and after mylar pic:

I picked up a MET last year.It was the second one that I owned. I love the game. The first game I used the washer fix. On the second game I tried it to no avail. I pulled the pinballs out and placed them over a small washer.One of the balls picked up the washer,it was slightly magnetised. I replaced the pinball and have had no more issues.

As this is still an issue, I don't really think this is too much of a thread necro... but, we were at Stern and talked to one of the guys about our issues with the ball getting stuck under the hammer. They knew what we were talking about and went and got a new "subway" for us. Said the original one was bent where the ball comes down.

After getting the new one and the old one side by side you could see the issue. As I was an idiot and didn't take any pictures of the replacement, here's a couple of pictures of the original one; with the bends and one after I manually bent them back to where they looked like the new one. The balls where getting stuck on the right side of the ramp (when it's installed, left as you're looking at it in the pictures). The ball would sit where the bottom was bent down. The new ramp fixed that issue, but if you're having this issue... check the bottom of the subway where the balls drop down in to it.
