Urethane ball doors

[Casey]

Just out of curiosity what kind of life expectancy do you guys get out of your ball doors?
Ours were put in 5 years ago when we converted to PBL's. I am just now starting to replace them one by one. What causes them to bust? I keep my bolts tight. Is it caused by a ball coming full steam ahead at just the right angle?

Another thing.....how in the hell do larger mechanics fit in the machine? I'm just an average sized guy and have a hell of a time. Especially in the ball lift area! Pain in the butt!

It is tough to get my big a$$ in the machine....lol

Replace the urethane ball rings with lifelong ball rings.......they are built like a tank!

Re: Urethane ball doors

I was just looking at those, the picture on the website appears much different from the AMF door rings. Is there a LH RH side? (only saw one part number) do i need to drill new holes in the machine? fit 82-70's?

not much info on the site about that. its steel right? does that cause ball damage? When I started working at the center I'm at...all were already converted to urethane.

Whatever makes my job easier makes me happier and my boss happier!

Re: Urethane ball doors

Getting in is a pain in the arse. On the 70s it aint that bad, even when I gained the "freshman 50" my first year of college. I was about 255 then, now I'm about 205 and work on 30s, so It's still a pain in the arse, LOL!!! I have to close a couple of respot cells to squeeze in the pit and avoid ripping the wiring off the switchettes. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

Tank my a$$ queenie!! Ours were installed in 98 and the welds are broken now. I have installed the urethane (black/red) ball doors from AMF in 99 and they are still runnin strong. Do not tighten them too tight.

Re: Urethane ball doors

The lifelong doorings are 1/4 inch steele and they do not damage balls. I have had to replace only one out of 22 over four years do to breakage and it was an easy weld job. I wish i could say the same for the belt. Although they have been very good at replacing the belts and the newest design has proven to be reliable.

ROFLMFAO!

Jerry, I can't tell you how many pair of pants I have that are ripped in the @$$ because of those cursed respot cell cotter pins! Now, I've decided to hang the curtain back up and crawl OUT THE FRONT! I'm 5'7, and weigh 175, and have a hard time working in the pit.

I got the name StuckInThePit that way. A few years ago my clothes got hung up on something, and I had to have someone up front come back and help me out of the machine. I STILL ripped my clothes to ****, though, LOL...!

The head mechanic I now work for, knows what color underwear I have on, but she won't admit it!

Re: Urethane ball doors

We've been switching to the Lifelong door rings as the urethane ones break. Urethane were breaking within 2 years of install. Put the first pair of Lifelong's in 4 years ago and haven't had any problems. Haven't even had to tighten a bolt. I believe the part # is LL300-005-6 for the pair. They need to be installed in pairs.

Re: Urethane ball doors

We've been installing Lifelong Humpbacks and ball doors, you have to use their ball doors for humpbacks, but we also replace the old AMF and urethane doors with the Lifelongs.

It's fun to wedge my 5'8" 350lbs into a machine [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] to change ball doors, but with someone in the other pit, it goes quicker.

Re: Urethane ball doors

We installed 4 urethane door rings (not weldments [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] ) with 2 PBL conversions and they were broke in less than 2 years. The Lifelong's are the best way to go IMO.

Re: Urethane ball doors

unless the urethane ball doors break in the back, where the pinhead can get wedged where the paddle arm comes through, so what. its a urethane ball door which isnt gonna hurt the ball anyhow. lane 12 has been cracked @ 5 o'clock for about 5 years.
