8230/8270 Front Roller

[ModelTech]

This is a question for BOTH machines:

What is the "correct" distance from the front roller to the tailplank?

I've seen 'em all over the place, even a gap wide enough to put my hand in and retrieve a dropped spanner! Pins lodge there, and roll until another pin hits it...

Then, our new machines have about an inch gap between the front roller and tailplank. My chief doesn't like it, because, she says, it's almost impossible to do a pit job.

They were pretty close on our old 8270-C's, back at Miracle Lanes, and I never had a problem with the front rollers. I usually don't need the "L" pry bar, as I've gotten pretty good at pushing it back with both my knees, as I roll it with my hands, put the retainer in each side...voila!

My chief says she wants to shim the pits a bit, but "pit rollers" are quite frequent on machines with too big a gap.

Is there a "standard" measurement for AMF machines? I've looked almost EVEYWHERE for that spec, but can't find it... [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

You need about 3/8" between the black steel kickbacks on the rear assembly and the frame of the machine. You should have a bolt holding the 2 sections together. There should be about 3/8" of shims/washers there.

Re: 8230/8270 Front Roller

On the new 8270 clones, there is a spacer (3/8"?) between the table frame and pit frame. She wants to shim it out further. I think she wants about two finger's width of a gap, between the front roller and tailplank.

The way it is now, you can barely fit ONE finger. The installation guy says that's factory spec. Fine with me, as long as we can get the front roller in and out without the bearing hanger gettin' hung up on the tailplank.

Been in the pit a lot this week. My moniker was well picked! :p

Re: 8230/8270 Front Roller

mine are all over the place
the machine's are in the right spot
it all depends on how big the carpet is
we cut two old one's in half to see the diff
found lenght wise after cutting it up one was 2" whole inches longer than the other Makes a difference to where the roller ends up [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

<font size="2" face="Verdana, Helvetica, sans-serif">One thing you can do for this problem is nail or screw a board right behind each flat gutter. As the pin rolls toward the side of the machine, it will hit the board and and be pushed back into the pinwheel. However, these boards also make it harder to get the front roller out. Another thing I have seen for this problem is a board bolted to the sweep shields, so that every time the sweep went back, the board stuck out far enough that it knocked the rolling pin back.

Louie! Great idea! Nail a board to the tailplank!You're right about getting the front roller out. We thought about that...

I guess there is no "spec"... [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]

Good to hear from Louie, Pulse Tech, and Kat! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

Was also hoping to hear from Gman, 8270/King, Rep, Dirt Man, Androoo...?

Are ya there, guys? [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

Re: 8230/8270 Front Roller

I've cut strips out of an old carpet and nailed them behind the flat gutters. Got rid of the pin on the front roller. Not much in the way of doing any pit work.

Re: 8230/8270 Front Roller

Since some of our machines were put in by a crew of three-handed, cross-eyed demons; none of the backends are exactly where they're supposed to be... in fact lane 1 still has a big burn mark and a groove ground into the plank where the front roller flange was digging into it after they were installed. Some we had to move or plate, since there was a big enough gap for the head of a pin to get between the wooden mounts and the steel pit walls.

The machines that had an excessive gap where pins (and sometimes balls) would roll, we cut a 3"-4" strip from a cushion rubber &amp; notched it back in the area where the roller flanges run, leaving the rivet holes in it... we put lag screws and washers into the holes so they would be recessed and not scuff the balls or pins, and lagged it to the tailplank about 1/2" below the tops of the flat gutters. Cleared up the majority of the rollers from laying in there, and since there was already a good amount of clearance in fromt of the carpet roller, it's no problem getting it out of the flanges.

Wonderful!!

Another bunch for the "tip" book! Thing's gettin' pretty thick! My chief LOVES it. Says we can use all the help we can get...

I'm thanking you on behalf of myself AND her!

Re: 8230/8270 Front Roller

We used to nail an old peice of dist belt to the tail plank on ours to stop the head of pins getting caught between the carpet and front roller hanger... those pins that sit upside down, spinning and if they get hit hard enough, knock the front roller out. All caused by old carpets that have been trimmed ect, but they still work.

Re: 8230/8270 Front Roller

Good one, Androoo! [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

Yep, that could happen. Hasn't popped one of ours yet, but I'll be checking that out this week. I'm off until Wed.

Meantime, I'm compiling a BUNCH of problem-solving ideas from this site. I wonder if anyone's thought of publishing a book? There are enough mechanics, AMF &amp; Brunswick, that have posted here to make TWO books possible! [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img]

Our A-2 house in Cape Coral could use one (as well as the ones in Naples), and so could OURS.

I worked for author Stephen King for 6 years, so maybe he can tell me how to go about submitting something for publishing, as well as steering me to a reputable publisher. I'll get back to ya on that, and see what he says...

Re: 8230/8270 Front Roller

Oh wonderful...just imagine the cover of "IT" with a pinspotter breaking through...

I could just see the title now... "101 Tips On How To Kill Your Manager... And Some Machine Repair Tips, Too!"

Pet Cemetery? How about "Brunswick Cemetery"... Firestarter? How about "Motor Starter"...

How about a new release of 'Christine', but with a possessed pinspotter instead of a car?

"Plistine. The Chinese Via MC-2 From Hell"

Just a couple extra I thought of...
