Quoted from Crispin:

I just removed the mini playfield from the frame, removed the cross bracket to get to the set screws and moved the flywheel out on the arbor. Tightened it all up and now its running up and down smoothly! Hopefully when I get back I'll attach the rest and see if it can handle the weight. fingers crossed!

Quoted from Crispin:

yeah

yeah wishful thinking. I attached the playfield to the bracket and the same result. The motor wont lift the playfield up. I have to help it until the the wheel gets to the top of its run and then the motor will bring it back down until it starts to go up again then you just hear the motor working harder.

Quoted from Crispin:

Thanks for holding my hand through this Faz! I tried just adding the weight of the playfield on top of the brackets without screwing it in and it still binds in the same position! I tried screwing it in and the same result. I have a millimeter guage and made sure the the brackets are spread apart the same distance at the top and the bottom. The clamp I have the unit sitting in was too small and everything was leaning forward a tiny bit. I removed the unit from the clamp making sure that the bracket holding the motor to the assembly was parallel to the frame so the cam doesn't have any wobble. I placed her on the table and ran it again and the same result. I put a square up against the corners of the brackets to make sure they were truly square. Do I have to sacrifice one of my children to the gods to make this damn thing work? I'm about done with this game. If you're reading this and are interested in a doctor who drop me a pm. My friend can't work on machines at all so if he buys it I'm going to be stuck fixing this freaking thing again.

Quoted from Crispin:

Thanks Rdoyle it just seems like its not strong enough. If I apply pressure and help it the cam will run through it's cycle. Could it be that the 2 seconds that the ball was trapped as the playfield was going down weakened the motor?

Quoted from Crispin:

So do I get both a new motor and gear box? Do you know if Steve at pbresouce has em?

Quoted from Crispin:

I think that's what I have to do I can't find a 12v power source in the house. I might try jbwelding the lg gear onto the shaft just in case. Will report back tomorrow.

Quoted from Crispin:

Ok I was able to get back in the pin today and tried running the playfield in test. I have the same results, runs fine while gravity isn't involved but once the motor has to work against gravity it fails to lift the playfield. I helped the playfield up to the top in test and the playfield is slipping and falling down in the downward motion. Seems like it's getting worse so I bit the bullet and purchased a new motor. I'll report back when it's installed.

Quoted from Crispin:

Hi Faz, sorry I didn't see this until after I removed the motor. The new motor and gearbox arrived and I installed it and she works great! I'd like to thank you and Rdoyle for all the help. Hopefully this helps someone in the future when their mini playfield won't raise.

Quoted from SuperPinball:

So the only way to fix the optos is to remove the mini playfield?

Quoted from yellowghost:

Like here for instance?

Thanks pinball_faz ! I do have a 12v power source that I'm going to hook up, will report back once I get to that point.

rdoyle1978 The nails are mine, I'm getting ready to get them redone this week. I'll keep them updated in my posts along with my MPF reassembly progress.
