  • 82-70b Stepper Chassis

    There is a small house that has B's with these Stepper Chassis. I'm looking for docs, wire diagrams & anything too work on these beasts.

    Also if anyone knows the how to fix them when on a strike cycle it feels for pins then the table comes up and hear a load click then nothing usless you turn off the power and turn it back on then it finishes. The problem follows along with the chassis to lane to lane.

    Also the wire diagram for the masking units. I hear that you can use a new chassis just need to change the masking unit plug. Don't know if this is an option concidering budgets.

    Thanx PM if you wish

    Would love to see pics of the inside of one of those. Sorry, I'm no help in servicing them, I've only had some experience with the solid state and Mp chassis.

      Hey the house I started at in the 70's had these and the house I work at now has them. We have not chaged or updated because these things run so strong. We have qubica scoring hooked up to them.

      As far as changing the plug for the masking unit thats not a problem either. I imagine you are talking about a Zot conversion. Not a problem.

      I will PM you with my contact info and I am sure we can get you fixed up.

      It sounds like you have a bad SK relay, or a bad diode board to me. Have you tried only changing the stepper and the problem move with the stepper?

        <font size="2" face="Verdana, Helvetica, sans-serif">So stepper run like a tank. Good to know.

        Since the problem was in another house not mine I figure I would lend them one of my spare elco chassis while we figure this and another chassis with a unknown problem. ( as in I havn't gotten that far)

        I also havn't done any hands on diagnoses at this time and only know what I posted. Hoping for places to look when I get a chance at it again.

        For those who want pictures I'll see what I can do.

          OH MY GOD!!! Is that 20 plug in relays for ONE chassis that I see in the picture? What are the 2 large white things next to the S &amp; T contactors- are those also relays? Would love to see a close up of the stepper. Do your 82/70B's have the counter balance springs on the sweep links or was that something found only on the A's? Thanks for the pics that thing is pretty cool.

          Does anyone know where I can download a copy of the manual?

            There is a 40 laner localy that used to have 32 of them, but they have converted all but 3 to S/S chassis with Omega Teks. The head mech. really rarely had problems with them. Mostly things like contacts or a bad diode. They were intimidating to look at, but pretty reliable.
            I've had enough of hope & chains.

                Yea most of the realys are for respot switiches. The white things are just two more realys. pm me a fax number and I will try to fax you some of the pages.

                  I'll let you know ASAP, I'm not sure the head mechanic is there or the B mechanic. B mech. won't be able to let me know whats available.

                    I would be very interested in the steppers and maybe some timer and diod boards. I do not need the whole box. Less $$ to ship.

                      <font size="2" face="Verdana, Helvetica, sans-serif">Beast of a thing isn't it? You now know why the chassis space is so big on 70's. The Stepper relay plugs in like a huge C1 plug with like 50 pins or so. The place where I've seen one and was ask to help is a private members only club and the big boss isn't big on the bowling center they have. So I havn't gotten back together with the mechanic of the facilities to see about getting it working. Tho still look to any manuals that may aid in this. I don't think anyone has a copy of the manual on the internet to download at this time. As for counter balance springs I didn't notice them. The B's basicly look like C's. Just mainly the chassis and two solenoids on the front for spotting but some C's had that too if I remember right.

                        Yes, where I am at currently they are all C's (maybe B's that were converted, not sure) that originally had the double solenoid setup. Most were converted to single solenoids so we still have a few, very few problems. The only thing really that ever happens is the pin/screw/ or nail that goes thru the respot soleniod link and hook and bushing ass'y breaks off which results in tilting cups during respots-but that's no big deal really.
