Table Drive Assembly

[Guest]

The lever that pushes the little bar that lets the accentric turn doesn't push hard enough. If I take my finger and push on it at the same time the selenoid clicks it works fine. What adjustment am I missing here. Thanks.

I couldn't be more tied down if I had 100 milkcows

Re: Table Drive Assembly

I dont remember any special adj. there but I do remember that if you have a lump of wet grease in the notch that it kinda holds on to the latch and wont let it pop out.....just a thought...

Re: Table Drive Assembly

One possibility is that you have a bind in the linkage, possibly even a bent link, between the solenoid and the flag. Check the resistance to manually operating the solenoid with another machine. If it is stiffer, check the linkage closely.

ED; correct me if I'M wrong but didn't you mean to say a dried up lump of grease like a bugger in your nose
[img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] now that would make it hang up. :p
I hate picking that stuff out OF MY NOSE and then I can't figure out where to put them so I just put them on the balls going back. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] CRUD

Re: Table Drive Assembly

Try tightening the 4 bolts that hold the spot solenoid to the bracket. If these are not tight enough the latch will not lock causing your problem. To see if they are tight enough, engage the solenoid by hand and try to lift the latch. If you can lift it, it's not tight enough.

No Cruddy Buddy...I meant wet...I know this from experience because when I was a weeee little boy many many moons ago.....I wanted to help out the mechanic and go through and grease all of the coconuts....I went through all 32 lanes with the gun and loaded them up. Of course the grease oozed out of the seems and left a nice coat on the exterior of the assembly. Well....about a half an hour later the league fired up ...all 32 lanes may I add....and after about 5 minutes half of the tables wouldn't spot pins anymore...... [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] the mechanic informed me that the wet grease kind of creates a vacuum and wont let the latch release....I don't mean a film...I mean a LUMP of grease.....

Re: Table Drive Assembly

Spankey,

Usually the problem is the holes the roll pins go through are worn. This is on the small shaft that is spring loaded. This does not allow the eccentric to disengage to allow the spot cycle

Re: Table Drive Assembly

Hey Spankey, I think 82/70 is on the right track. If tightening the four bolts do not help remove the rubber spacers between the solonoid and mounting plate. Good luck.

Re: Table Drive Assembly

When I started working at Greenbrae full time, I ran across a TBL drive assy that had been rigged years before. It had a Popsicle stick taped to the under side of the cam lever. [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

Re: Table Drive Assembly

adjust the TA1 cam/lever to stop the table earlier.

yeah I know about too much grease in the table dr I'VE had a few guys think there doing me a favor over the years and go along and put three pumps in them and the same thing happened [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] were you trying to sabotage the machines :p
I never grease them only when I take them off and take them apart.
when i'm getting low on grease I just take off a few then I have enough grease to last for another year [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] .
when I put them back together I grease the bearings by hand real good then give it one pump of grease and thats it for ever other then oiling the bushings once a year.I hate having a big mess.

Re: Table Drive Assembly

Wait a second...I got to right this down before I forget: "Popsicle stick under the cam lever", "electrical tape around the S.S." and "9/16 socket under the pit leveling bolt". Am I forgeting anything? Good. Carry on. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

Re: Table Drive Assembly

Spankey: Take a look at the spot solenoid plunger, too... if it has excessive wear spots, rust, or any kind of gunk on it it could be hanging up and not pulling hard enough... Excessive wear spots on it indicate that the plunger travel is not linear anymore... it's shifted out of line and rubbing against the sides of the plunger run. Rust or gunk on the plunger can also cause it to hang or not pull.

Ed: Never heard of wet grease affecting it that way... ours pull so hard I could probably glue them down, and they would still rip it free... definitely nothing a little grease is going to stop... Actually, ours hang up if they don't have grease on them... I hate working on the table drives. By the time I'm finished, I look like I was rebuilding an old dump truck engine. When I was an assistant, the previous mechanic used to bitch at me if I didn't keep the front end greased. But then again... these friggin machines are demonic to begin with... and they seem to hate me with a vengeance.

Jimmy: Umn... how about gluing washers to the ball lift stops to make them higher... using a distributor linear spring on the back finger pivot to force the fingers to open faster (or to make them open all the way), bending the distributor trip rod linkage to make it shorter, using a plug from an electric frying pan for a back-end motor plug, putting springs on the ball lift to make it go down with a bent shock rod... need I go on? (The house that we bought our new-side machines from had a VERY halfa$$ mechanic... there were 'rigs' on those machines that were so crazy that they should have been made illegal...but I guess they worked...kind of... Took us the better part of a year to straighten stuff out, and I still occasionally find one here or there)

Re: Table Drive Assembly

Bad bearings in the clevis eye (where the clevis is attatched to the table drive eccentric) will cause this problem also.
