Dizzy height above DurabinII

[Pin_Head]

Howdy folks,
What is the ideal clearance between the dizzy belt guard at the top of the Durabin at the rear from between the 8 and 9 pins.....

[8270guy]

Off the top of my head it is 1/4" - I think! You should be able to find a Durabin manual on the QAMF Customer Portal which will tell you for sure.

With all that said, I'm sure there will be someone here who knows!

I just checked the Durabin II install guide and this is what it says..

Swing the distributor left and right with it in the fully retracted position and verify that the beltguard clears the screw heads and raised moldings on the bin by at least 1/8 inch. Shim the distributor support as needed.

Reenergize the pinspotter and test the operation of the bin and shuttle. Adjust the distributor
and shuttle as needed.

So it looks like the 1/8" is a suggested starting point so basically whatever makes it run smoothly.

yeah just checked that myself WOW 1/8?? they were installed here and have 3/4" gap can fit my hand between belt guard and bin LOL best be fixing that then hey....

[Tablejam]

Yeah I know....1/8"? That seems like it would be way too close and just from normal vibration the belt guard would rub or get caught on the bin, unless of course everything is so rock solid that nothing ever moves or wears out.....ever! I think a minimum of 1/4" probably makes more sense.

That's also how they were installed at Joondalup 3 years ago. Same install crew. Go figure.

But, be careful when lowering the dizzys. Too low and you'll have the belt guard catching the second 8 pin in the bin and the dizzy will get stuck there or it will spin the top 8 pin around as the dizzy moves from the 8 to 5 pin positions.

Could the 3/4 in. gap be there incase of pins left in the cups , so the bin does'nt push up and catch the dist. I know that pins left in the cups is a problem, but a occasional idle ball at the tale plank could cause a pileup. ( just speculation)

I just discovered on the Qubica customer portal that there is a block kit called DurabinII 8 pin block kit, p/n 612-088-209 screws onto the Durabin either side of the 8 pin pocket designed to stop the 2nd 8 pin from spinning around in the bin....

I only have Durabins on one pair. After installing this kit, my calls vanished on this pair.

Here is the height of most of my dizzy supports...

I don't have Durabin anything but that looks like some of mine, they are all over the place. I don't think any two are the same, but that's what it takes to run well and how I like so be it.

Oh wow, side splittingly funny!!! How's life Carl? My old phone died so I need to get your phone number back again...Send me a PM?

Anyway, the way we rectified the problem at Joondalup was to get the top of the upper dizzy casting level (or there abouts) with the top of the steel channel at the back of the bin. Some machines had to go higher for the reasons Carl stated, but this was probably caused by the bent shuttle tubes and worn pin holders. Machines with square shuttles rarely had much difficulty in this area.

Hi, Brett.

I was wondering why I hadn't heard from you for a while. I've sent you a PM.

Are you missing the 82-70's? I have to admit that after 8 months I miss them a little. But, as soon as I climb up onto one of my beloved Brunswick Model A's the feeling soon passes.

(Sorry for the OT post, guys). I'd better go before they get me.

I have never seen so many washers under a dizzy support..
Although here, in the past, it seems the spacers for the post shaft were 'lost' and as a result the supports were raised to compensate.. but now most are running with just their original single 'shim' after putting the spacer back on all the shafts and as a result.. no pins through the 1pin bin, able to adjust orientation properly.

I'm with Sean on this one...I may have a couple with a fender washer under the original spacer. On a few I even took out the original spacer cuz I had room. Oh, and removed spacers on the shafts as well I like them as low a possible cuz the pins don't seem to flop around as much...If that's possible, feeding a round object on top of a round object, consistantly.
