      You take the caps from the back of a spotting cup along with the u bolts and sandwhich the ball lift shaft in there and tighten nuts on the u-bolt and walla.

      i have used this trick a few times before to get a league through a few frames.

      Just a little note though, doing this could cuase damage to one or more of the gears inside of the gearbox. it will also make the motor run hotter and if you have "shady" motors the clixon may give out or even destroy them.

            It's a quick fix to get you out of a jam... just don't get any ideas about saving $$$ by running the backends on a pair from one motor... You'll be changing out motors every few days.

            We never had to use it... 4 bolts, 1 shaft, and 2 belts isn't a big deal. Normally it only takes a matter of 5-10 mins to completely change out the backend drive... We keep 2 RH and 2 LH motor/gearbox setups as spares just for that reason. Most of the time they just collect dust... I think the last time we had to change out a backend mtr/gbx during bowling was about 4-5 years ago.

              Did a search reading thru mods. On the note of leaving motor and gearboxes as spares collecting dust, wouldn't it make more sense to swap out your spares on a seasonal basis? Find a pair that you think might be going out, is making noise or could possibly be bad. Swap your spares and rebuild? Simialr to how brunswick always says to rotate your spare electrical equipment? I don't know, will defer to someone who knows motors a little mor eintimately than I do. Just curious...

                Tech Tip

                Thanks to J. Shane White, Nite Mechanic at Triangle Bowl in Desota, Texas for sharing with us the following tchnical tip.

                During a full house league I had a pit motor go out, and I did not have a spare. I knew from past experience with failed clutch bearings that one pit motor is strong enough to drive the pits for a pair. In a moment of desperation, I took a 3" lomg piece of 3/4" diameter conduit and cut a slit in it lengthwise. I then bent the conduit in to a U shape. After that I used a pair of U clamps to fuse the shafts of the two pit motors together. This is definitely a temporary fix, but it got me through the league, and in fact, it lasted about one day until the conduit broke.

                  don't you guys ever get lucky and just have to change the head?

                  four 1/4" head bolts and it's up and running again... (usually)

                  And it's good to see you back and posting Felix.

                    Per Felix's post, he had no spare.

                      Does anyone have a pic of this. I still dont understand.
                      If it cant be fixed with a hammer, use a bowling pin.

                        I was looking over the machines this morning thinking how it would work. Are they talking about sandwiching together the 2 gear-box output shafts with 2 pin cup caps? Right behind the BE boxes where there is about an inch or 2 in between the 2 shafts?

                          If you have an inch or two between your backend motor rear drive output shafts, you should kiss the floor behind each machine. Most 82-70's only have a half inch or less there.
                          Prevent the problems. Don't do crash repairs.
