  • 1 to 1 question on timing

    I just pulled a 1 to 1 off at 0 degrees and while looking into the box, I can not see a timing mark on the 2 to 1 where it should be. Soooo.... would it be possible to have the 1 to 1 installed 180 degrees off from the 2 to 1? At first I was thinking no way but if the 1 to 1 was at zero degrees I am thinking the 2 to 1 could go in and run 180 degrees off (since it does turn twice during the cycle. Previous people would slap any old 1 to 1 one them, hence some machines have the wrong deck/scissors cams on them and knowing some of the people, probably just eyeballed things. Any thoughts??

    I suppose that it is possible the 2-1 is 180 deg off. And I think it would still run that way. Can you put it into 180 and then check for the timing marks on the 2-1. It may also be possible the 2-1 didn't ever have marks on it. When I was in Brunswick School they told us of this rarity. Let us know what you find as I am interested to know too.

      check for timing marks for the 2-1 and 4-1 connection. Are they present?

        I'm not sure what you're looking at. The timing marks are on the backside of the gear, visible when you remove a pipe plug. Two adjacent teeth on the 2-1 will have markings.

          From what I have learned, the timing marks on the gears were to aid the people assembling the machines in the factory. Now, if the 2 to 1 gear is 180 degrees off, there shouldn't be any issue, since the 2 to 1 rotates twice during a cycle.

          The timing marks should be on the left (7 pin) side of the gearbox, unless the gear was pressed on backwards (which I've seen happen). I have, also, replaced several 1 to 1s, and the timing marks were in their proper position as expected.

            No! I retract my previous statement! If the 2-1 has a timing mark then it would show up at 0 and 180 degrees. If you don't see it then it is not there or it's too dirty to see it.

              If the 2:1 was 180 degrees out of time with the 1:1 , the deck lowering hook cam would be 180 degrees out of time,which would not allow the deck lowering hook to lift.

                As Ewen pointed out, the machine wouldn't function if either were 180 degrees off. However, if it were possible they would have added two sets of timing marks.

                The marks may be there but not visible, or it is a defective gear and they were never there in the first place.

                  I am not sure what I was looking at either at the time. I was looking at the larger gear on the 2 to 1 for a mark, not the smaller one. To tell you the truth, I cant really see sh*t these days, I have a cataract in my left eye so I cant really see anything but shapes !! Having cataract surgery on May 22th on the left eye, the right eye isnt too bad yet, that one can wait a year or two if I wanted to they told me.

                    Prepare yourself for a big suprise after the sugery, its simply amazing, how much better sight is afterwards, especially at night . Headlight glare is also minimized. You'll love it.

                      I dont believe the timing marks are set to a specific gearbox degree.
                      They are placed so that you can view the marks without assemblies in the way of the sight hole.

                      It has been a long time since I did a 1-1 in a machine.
                      I normally change out the entire gearbox instead.

                        I know my wife will cause all I do is bitch when she drives, but I should not be driving with my sight the way it is, I only go back and forth to work cause I know where I am going. Actually should be driving anyways, license expired the other day, cant pass the eye test this time around. I just wish I could get it done quicker, took me 6 weeks to get in and see the guy and have to wait 6 more for him to do the procedure. Gettin really tired of wearing these flip down magnifiers and having the computer screen set to 200% just to read it.

                          I only changed an entire gearbox is if the housing had a crack, or if threaded holes had been stripped out. Otherwise the gearbox was rebuilt while remaining on the pinsetter.

                          Marty - good luck on the eye surgery. Cataracts can be fixed. I have glaucoma that can't be fixed.

                            Brain fade. I was thinking of the gear that meshes with the 4-1.

                              The gear box can be changed out quicker than any one single assembly if you have a crane available. We have posted many versions of a crane here in the past. Simple to do if you have the proper tool.
