Yes, remove that cover to access the hinge nuts. The cover is held on with three screws, easy off.

I have had a Stern premium Jurassic Park for about a year now. Recently the T Rex about every third or fourth time has been dropping the ball all the way to the left ( it’s right) and the ball gets stuck behind the guard tower. I’d understand if it was going it every time it’s probably an adjustment somewhere but it only does it like I said but generally you can’t get through a full game. I have to pull the glass to get the ball out. Any ideas why it would only do it occasionally?

Do you have a mod on the tower? Only asking because I recall some people with a decorative mod for the tower have had issues with stuck balls there.

Whether or not you have a mod, you can try placing a cabinet dot or two in the area where the ball is getting stuck to prevent it from happening or you can disable random throw from the T-Rex settings so it will only return the ball to the wire form.

Posting a picture of the spot with a stuck ball there could also lead people to have better suggestions.

Here's the thread on the coin door mount: https://pinside.com/pinball/forum/topic/stern-insider-connected-qr-code-reader-coin-door-mount#post-6621582

Yeah, you have to take off that cover. Make sure the machine is unplugged before you take the cover off and stick any tools inside that area, there's 115v-120v in there even when the machine is off.

Also, you can just get raw metal hinges from pinball life to send out for powdercoating so you're not without your game while it's being done:

You only have to do this once for about $200, and then can just roll your extra set with each new machine, or even have the powdercoating done in advance of each machine so it's ready to install day one.

The "throwing" is random. Trex rampage and Trex multiball have random throwing. The other TREX modes drop on the wireform.

As others have mentioned you can either turn off throwing in the settings, or remove/fix the raptor tower mod that's installed but not factory. It looks nice but creates a ball trap.

I just took the T-Rex apart again. I put spacers between the upper jaw on both sides and the rubber body where it doesn't interfere with the opening and closing of the jaw. My T-Rex now works perfectly. It's been months and lots of head banging but I think I have it.

Do you have any pics or are you able to highlight on the assembly diagram where you put the spacers and what size they were?

JP T-Rex assembly (resized).jpg

Directly above where the lower jaw hinges to the upper. In coil test if the jaw is stuck open and you use your fingers to spread the rubber body it will snap shut. I just needed minimal spacers to give the lower hinge clearance.

I've suspected that a lot of my jaw issues have been due to the "rubbing" of the mold as well. Can you please show pics or if you don't want to dismantle the assembly again, then like Manny65 said, download and mark-up that diagram to show where you put spacers in between what part and what spacers you used (model number)? That would really help the community!

I was rushed for time and my fix isn't very professional and may not be permanent. I wadded up post it notes (one on each side) and basically stuffed them up it's cheeks. I then made sure there was clearance and the lower jaw wasn't contacting the paper or rubber. It proved the theory but maybe someone can improve the fix. I won't be able to work on it again for over a week. The paperwad spacers are nearly underneath the eyes sockets. I'm also in contact with Pablo at Stern to see if he has any thoughts. I hope this helps for now.

Bump! Want to be in the know!

Where did you get those apron cards from?

Hey Rat…. Check in with Mr_Tantrum here on Pinside. I have ordered a few magnetic apron cards from him and the are VERY nice quality.

I believe he had several to choose from…. Good luck!

I actually offer both magnets & apron card options. Since you are outside of US the cards would be the most affordable option since I can send those in a standard envelope.

You can see some of the designs here: http://aproncards.com/index.php/nggallery/pinball-apron-cards/jurassic-park-stern
Please PM me for details.

Here are some more that are similar to Gotfrogs's cards in case you are still looking

hey guys im sure this has been addressed but a customer has a premium and all of a sudden the trex is LOUD . It sounds like the gear box . The trex works fine but i think it might be on its way out . is this a thing with this game . thinking of asking stern to send me a new gear box.

The Review:
I got a Stern Jurassic Park Premium Pinball in 2022

Is their glass off? Did they turn the sound down? Serious questions if it’s coming from a customer. I’ve found myself alarmed of the sound a few times only to realize that thing actually is kind of loud when things aren’t drowning it out like normal.

Can you or should you put some lubricant on t-Rex? I have had mine a couple of years but I never realized that it made creaking noises until I installed some headphones and now I can hear t-Rex moving when normal sound is going to headphones.

Well I thought I had it.... but game last night my Trex ramp opto( skill shot....advance paddock...) only registered 1/2 the time. I had tightened it and cleaned it. no real adjustment that i can see... Seemed to work fine for a couple of games. So frustrating when you have a decent game going....

Put in a service note with Stern......

Traded my premium out for an LE. On my new LE, the raptor is positioned differently, it’s head is much lower / tail higher in the default position. Still works. It’s (the magnet stack)all the way down on the metal lever that covers the switch, so not sure what’s up, compared to the premium. Maybe bend the metal lever/switch that it rests on or shorten the magnet stack under the tail? Anybody noticed different machines with different raptor resting positions or do I need to adjust something? Don’t really feel like digging into that raptor pen.

I don’t recall where the images came from but my husband had them printed by mpix.com in a really cool metallic finish. I think they look great.

Pinstadiums with mirror blades or game blades? That is the question.

I hate pinstadiums so I can't answer.

I have them with Stern blades. Thinking of switching to Retrofurbs blue ones. Like them a lot

I have Pinstadiums on all 3 of my games and love them. The Munsters with the small lower playfield ones is awesome

No familiar with the retrofurb blue ones

Actually, there are two different 'blue' blades that tie into the backboard decal:

https://wizardmod.com/collections/wizblades-pinball-blades/products/jurassic-park-stern-pinball-wizblades

Just pin stadiums I wouldn't add blades... personally not a fan they always get scratched.

problem solved. you might even have something around the house that you could use instead of buying these.

Anyone up for sharing some pics of a close up of this Barbasol mod install? Got this amazing (no longer in production - thx Robby) mod off a friend and it was pretty mangled - I think a previous owner was running another mod power off the wires. Trying to figure out where these 2 wires go. I assume into the plastic connector but I want to be certain!

921F81F4-73FA-4D9E-9C1A-F826035BFEB8 (resized).jpegF4D1F139-72B8-4D74-96F2-163256D8F3EC (resized).jpeg

I can't advise regarding where the wires go, but you don't won't that fuse or fuse holder coming into contact with the earth braid, other boards or bare connectors (eg coil lugs).

I have 2 random issues on my Prem I need help with.

1. Sometimes on startup the raptor gate doesn’t go all the way down or it goes to the bottom and stays there. I don’t see any wires under the PF catching on the gate. If I power cycle that usually fixes it.

2. Sometimes the ball only goes halfway up the right ramp but it still registers. I went into switch test and I can’t replicate the issue with the ball or tapping on the PF or the ramp.

I have that happen also, the micro switch at the top of the ramp on mine is working properly and the wire needs to be moved a fair amount to activate it. So I can't see how a ball going halfway up the ramp would cause it to activate. Yep banging the ramp with my hand or the playfield doesn't active mine. But a ball rolling up there smoothly and back down often does.
I don't understand. But it's no big deal and the game is so hard that it's only fair that sometimes it throws you a freebie

Put the home pin translite in my premium. I really like the look over the raptors tonsils!

C9533AE8-0474-43BE-A432-5F5A79C33BE2 (resized).jpeg

I totally dig that translite as well! Assuming it's the same level of quality as your premium?

It’s actually better quality than my premium translite is. It’s thicker and has better light dispersion. I’m not sure why??

What are the wing looking things on the back of the dinosaur on the right? Or is it some kind of flat rock he is coming out of? Just looks out of place to me.

Where have you guys been getting these home pin translites? I've been searching everywhere for one, I can't stand the translite in the premium.

It's a spinosaurus.

Spinosaurus (resized).jpg

Oh, so I guess the thing on the right is a tree. Just seems like weird placement and looks like he disappears to the right of the tree I guess.

I see what you mean. I think it's just a weird perspective thing though. To me it just kinda looks like the dinosaur is "curving" its body pointing back towards where the tree would hide it.

Personally, I still think the Premium has the overall best art package, including the raptor themed translite. I'm really just not a fan of that cartoon Jeep vehicle (although the T-Rex does look pretty awesome). I know it is on the cabinet art of the Premium, but I can handle it as long as I'm not starring at it on the translite.

BTW, the Spinosaurus reminds me of this guy trying to hide behind a pole.

That’s a fair point. It is a hard game. I adjusted the switch so it’s less sensitive but if that doesn’t help I’m not going to worry about it.

I need to put in a lighting order, and since I've had several ask I thought I would do another run of my sling dino eyes.

Price is $30 for the pair of eye lights (includes US shipping), and cutoff for orders will be midnight central tonight. Order includes the full set of 2 eye lights with everything needed to connect them. Please PM me if interested in getting in on this run.

I make the pair of lights using a special 3D printed casing (different for each side), and the lights are installed without any disassembly of the sling plastics (full instructions are provided), and work with or without plastic protectors. The bulbs I utilize are non-ghosting, and are connected via alligator clips (i.e. non-destructive and easily removable) under the playfield to the lower sling LED socket. This way the eyes will flash when the sling flashes and be solid when the sling lighting is solid.
