    Hey guys,

    I'm back with some more questions hopefully someone can help me out with.

    I have been having trouble getting this 9810 to feed properly. After studying it to see if there was something odd that was happening, I noticed that the feeler fingers seem to be coming down way too early and paper is bouncing off of them half the time. After taking a look at how the 360 operates, it's obvious that something is off. Here are some pics I took of the two presses. All pics were snapped just as the feeler fingers were starting to move.

    I'm thinking there must be adjustment someplace but I can't seem to find anything for it. Please shed some light on this for me!

    Thanks!

    Looks like the suckers arn't moving forward. ?? check to see if a spring broke just inside the operator side cover.

    I wish i could watch you try and feed some paper that would help out alot. Have you taken it all off and cleaned it out real good? oh **** haha didn't realize the first two pics were the 360 haha. that has to do with timing, timing is everything on these old boys. I will look for my book and see if it has anything about that in it and get back to ya. Its not gonna be fun to do but you need it done bad!

    pull off the plate (6 screws) covering the sheet seperators and check to make sure the hoses that are attached to them are running smoothly(too long or short). Let me know what you find.

    If memory serves me right it should have a cam on the non op side that may be adjustable, my book is the year after they stopped using feeler fingers so I couldn't refer to that. I would think you can tweak timing a bit tho and not mess with that that's what I had to do on my ryobi 3200 which has fingers you are probably better off having a tech come in and do it so you don't make your problems bigger

    Bill - the suckers are moving forward. The problem appears to be that the fingers are coming down too early. As I stated, the pics were snapped just as the fingers started to move.

    jaed - I'm not sure that the hoses have anything to do with the fingers. I'm not referring to the sheet separators.

    I've got an old book hanging around that had a couple possible adjustments in there. I made them yesterday. Just need to fire the press back up to see if they made any difference. I'll post back with the results. Thanks guys.

    be careful taking that plate off, i think that there are spacers under it and you dont want to lose them. by looking at the pictures im guessing that the timing is out, and from memory so i could be wrong on the operators side there is a round like plate with aq bit missing out of it and the paper suckers run on thiis on a bearing, hope you understand what i mean, in the centre of this i think is the tensioner, it may be possible to undo this and change the disk position so that the suckers come down at the right time, get the side panels off both machines and turn them over by hand see how far off it is. as the paper is lifted from the pile the fingers should go down to separatre it from the rest of the pile check this on the machine thats running like i said its been a long time since i worked on one of these

    Yeah Plotter he is asking about the Feeler Fingers not the Sheet Separators. If you have never used a pre 1985 ab dick press your prolly not familiar with the fingers cuz they did away with em in like idk 86 or something like that cuz they don't really serve a good purpose.

    yeah your right ii got confused, the three fingers that feel if a sheet is under them or not, still think its a timing error though, or ad advise to check the top rubber rollers are spinning freely and that the spring pressure on them is enough to pull the paper through.

    Are you still having problems feeding? Most new operators going from 360 to 9810 tend to run to much vacuum. Turn the vacuum knob to full (clockwise) till you feel resistance, turn knob 6 half turns counter-clockwise and try to feed. To much vacuum on a 9810 holds the sheet to long and releases late giving the apperance of being out of time.

    Also the paper sensors work off a cam on the non-op side no timing needed. Symptom could be from a set screw coming loose on the operating lever which can be viewed under the springs on the gear side next to feed roller levers it would not lift the sensors and cause impression to engage while in idle. It is a 3/32 allen screw. I am an ABDick field technician and a Print Technologies College Instructor.

    also as you turn the handwheel when the sucker tubes move fwd, do you hear a clunk?? if so you may have a bad timing gear...

    Ok, sorry I haven't responded for a while here guys. Been fairly busy as of late.

    ghuerth - thanks for the suggestion. I'm no "newbie" here. Just a new press to me that hasn't been run in years and trying to get it back to working order. I actually used to run a fleet of 9810's by day and come back to my shop at night and run 360's.

    Anyway, after making some adjustments, the press is running MUCH, MUCH better!

    I made adjustments here...one is buckle and the other actually moved the suckers, which is what I believe really fixed the situation.

    My next task is to get a set of rollers. I've never run the stock alcohol system until I started running this press. It hasn't been too bad but I believe the old rollers are holding me back from getting a better ink/water balance.

    Also, I have this other extremely frustrating problem. On the delivery end of the press, the op side guide seems to be stuck. I can not get the damn thing to move. Anyone have any ideas? The upper part with the brass bushing seems to be fine but the lower part with the thumb screw is definitely stuck...

    Any ideas would be welcome.

    Thanks!!

    glad to hear you got your issues taken care of.. as far as the guide you can use some automatic trans fluid for a few days and tap it very lightly.. do not use a hammer on the guide, find a old cutting stick and place that by the part thats stuck then tap the cutting stick with the hammer... something that will take the impact! also make sure you dont hit the shaft it slides on so you dont have issues moving it later on..

    Hope this helps.. let me know if you need any parts i have over 50 of these presses in stock! !!!

    Mike

    Thanks Mike.

    I've screwed around with my form rollers to get somewhat of a stripe for the time being. At first I hardly had anything on one side, so I've increased the pressure a good amount just to get it to run. I'll have to take a pic of where it is now.

    My water mix is 1 1/2-2 oz fountain sol, 4oz alcohol and the rest with water. Does that sound ok? Running baseline poly plates.

    I'm going to get that guide soaking now too...

    Thanks

    4 oz of 99% anhydrous alcohol is minimum factory specs recommend 8 oz per quart and adjust as necessary.

    That's what I started with. I have since moved to 6oz and seems to be cleaning up a lot easier.
