    Hello, i installed the Pinball Lifes shaker motor to my new TMNT, unfortunately its much too strong.

    I have a shaker on my DP which is 1/3rd of the power, much better. Rattling tape won't help with this problem.
    The in-game settings just provides quantity not intensity.
    i can not turn the weights because there is just one pre drilled hole in the weights mounting pole to lock the weight in place.
    i thought about cutting the weights in half, bad idea? any other options, something electrical maybe?

    Is there a threaded rod in the metal housing that goes from one side to the other that you can tighten? My old shaker in my Star Trek Pro had one for that very purpose.

    You can try a step down converter like this.

    Or you could use a adjustable motor controller like this.

    I'm sure others here have some more ideas to slow the motor down. I am against the idea of cutting the weights due to it's a balanced assembly. You would have to weigh each weight on a postal scale to get it right or run the risk of burning up the motor bearings prematurely. Hope this gets some ideas in your head for you to play with.

    Following as I've gotba customer with metallica same issue.

    Don’t think you can use these in spike games.

    I always thought a shaker was inherently an unbalanced system. Hence, the shake. The weights are intentionally offset. So if you’re saying a gram on one end or the other is the extra weight that will throw the entire system off, I’m crying foul.

    They are designed to shake,yes but the weights are equal so that the shaft does not tear apart the motor bearings.
    These are just a smaller version of what we use on our dump trailer bodies at work.
    Furthermore some shaker weights are offset, some are not. If you have the weights offset the motor spinning will give less vibration but it will last longer. We can usually get 4-5 yrs from the offset weight style motor at work.
    The non offset in our clay bodies last about 2.5-3 yrs depending on how long the driver has it on to get the body empty.
    So you don't think I'm full of shit, here is a video of a dump vibrator in action.

    You would be putting this in between the vibrator controller and the motor itself. I'm not sure how the mpu would know you slowed things down since it's after the controller.

    yes, i thought about this too and i tightened it to a point where the metal frame got slightly bend.
    i didn't want to go further because i wasn't sure how tight i can make it and how it affects the mechanics. any idea?

    also what do you think about cutting the weights?

    I think you can rotate one weight. If the weights are both pointing in the same direction you’ll feel the max imbalance (shake). Rotate one weight 90 degrees and check.

    thanks but in my first post i said that i cant do it, because the pole has just one hole where the screw can be locked in, i cant use different positions of the weight.

    I always thought the PBL shakers were good, this sounds like a CT "Red Tremor" motor. Those were ridiculous...

    I’m not sure for this version. On the old shaker I had which was compatible with the SAM system, I tightened the rod pretty much all the way. To make things even more fun, the rod took a flat head screw driver instead of a Phillips. I’m pretty sure I stripped the screw getting it to where I needed it to go. Perhaps contact pinballlife before you do more.

    thanks, i tightened the screw even more now and the housing really is bend, but it works!

    cheers!

    Oh good. Though I’m not sure the housing is supposed to bend, but if it works . . . .
