Looking to install my first new disc in my Tron since the original black one.

I have got a blue disc coming and a brand new surface to put it on.

I have heard a lot of different opinions on the best way to install it.

Please share any info on what worked and what did not work for you.

If you did use additional adhesive please let me know what it was and how you applied it.

Thanks in advance.

I used dditional adhesive, Loctite 200 Spray Adhesive.

* Pulled the old black off the original hub and motor, have to do so to get to the 3 philips that keep the hub to the motor.
* Sandpaper on the new hub surface that will get the adhesive, wiped clean with alcohol on a rag.
* Screwed the new hub into place on the motor.
* Painters tape to mask off the outer, raised ring on new hub as best I could, with a knife to make it clean.
* Sprayed both the back of the new poly disc pieces and the top of the new hub.
* Waited 1 minute, fitted the pieces together.
* Pressed them together to intermingle the adhesive from each part.
* I used alcohol and a rag to clean off the excess adhesive, trying to minimize any alcohol getting in the mix between the hub and disc.
* Left upside down for 24 hours, with additional weight on top of the motor housing.

So far I'm at 3 months with my current disc staying down and in great shape. The second time I replaced the disc it didn't get quite as much treatment and lasted 3 months before pulling up; only about 30 minutes upside down with only the weight of the motor, no sandpaper, no masking. The first time lasted 5 months (on a multiplier of fewer plays), used super glue at one point so that it could be playable by League, but boy did it create one hell of a flapper (don't use super glue, for Many reasons).

I love the clear disc! I hope the blue is as much fun!!

I used 3M spray adhesive and installed on a brand new clear disc from Pinball Life. No issues ~6 months in.

The first one adhered fine and was ok for about 6 months before the outer ring came off and the center ring started lifting. Had purchased two at the same time, so before I installed the second set - I used the spray adhesive and no problems since.

I did, the key is to spray the adhesive on both surfaces and allow them a few minutes to "tack up" before adhering it. Did mine one year ago and it is still perfect with no edge damage.

I had bad luck with spray adhesives. It would hold for a bit then fail. I switched to epoxy. No more issues.

I used 3M double sided tape on mine. Still good after 2 years.

Stern support told me that they use Loctite 460. Never tried it though.

Quoted from gripwhip:

what expoxy?

This is silicone disc material, correct?

I will have to check when I get home. I don't think it was anything special other than a regular 2-part clear epoxy.

#11 4 years ago

I used PermaPoxy 5-minute All-Purpose Clear epoxy. Worked great for me. Yes, the disc is silicone.

#12 4 years ago

I used 2 part clear epoxy. Has held up for a couple of years.

I have to resurrect this post: for those who used 3M adhesive spray to install clear disc, is it enough to use Super 77 or did you use High Strenght 90 ?

Just FYI, do NOT use GOOF OFF to remove glue residue. It will attack permanently your disc !
