I see the washers, but not the bearings. It looks like the standard rollers. Is this something different?
Someone a few years ago made rollers out of UHMW Plastic. I tried to get a set but the guy went dark on the forum.
If you end up creating some, I'm in! I should try doing this myself. I have a lathe and plastic cutting boards that can be sacrificed. However, there's that 'skill' thing I don't have for turning small parts.
More pics and vids!
btw... that's the coolest freaking test jig!!! An over-engineered wonder (like the MPF in the first place). Zofia Bil would be proud. I LOVE IT!!

That is SO sweet! Nice work.
Having tools AND skills.... what a combo! I have lots of tools....but alas, a fool with a tool is still a fool
What's the top of the MPF look like at the top of the stroke? Any wobble or did that new AWESOME bearing/washer combo fix that.
Thanks,

Quoted from darkpinball:How durable are the washers?
How durable are the ball bearing on the shaft of the cam?
Consider that mostly collectors / DW worshipers are going to be applying this fix.... it probably won't be seen on route. If it does find its way on route, the operator is a class act that want's the best for his machine. If it fails, he'll kick in a few dollars for a replacement for a great machine.
Make a call for "beta" users. We'll test it out and tell you what works / what does not work.

I think the bigger issue might be the modifications that you are making to the fasteners. I can't drill/thread the posts. This could be done as a service, but the shipping would probably make it an issue.
Is there anything you can do to make the e-clips survive? Super thin / high density washers, sheet material to coat the bracket... or a sleeve that goes over the existing posts that extends the reach.

There was a post a few (5-6) weeks ago of a unique design. I can't find the post.
The side brackets were replaced two rods about 1/2" diameter. Pully rollers (or something like that) traveled the length of the rod.

Loosen the screws holding the bracket on the main playfield and the MPF. Then push away from that corner; retighten. If that does not do it, the frame is bent and will need to be tweaked. A bar clamp is good for tweaking.
You can also elongate the holes. Is that an original MPF surface or the CPR repro?
