Deck lift shaft height adjustment

[Carlo]

Does somebody here have a sketch or video how to adjust the deck lift shaft height. I want to know which spot on the pin deck and the deck lift shaft in able to obtain the proper height.

You will need to use a 4 foot level, a tape measure and the proper tools to turn the jack screws that you have.



Place the level on the pin deck by the corner pin on the side you are going to work on so that it is angled toward the kickback. (See image above) Place the tape measure so the end is on the bottom of the deck lift shaft. Place it as close to the frame of the pinsetter as possible. Measure from the bottom of the deck lift shaft to the bottom of the level.

Thank you so much steve, the picture really helps a lot. I have 2 questions , first is how USBC measures the depth of a gutter? do they measure from the middle of the pin deck to the end?or they just measure the end of the gutter by the ten pen spot?. The second is how to get this measurement,it says on the book to set the deck lift shaft at 15-13/16 in from the rear of the deck lift shaft to the center of the 7 8 9 and 10 spots.

I've found it easier to hold the level on the underside of the shaft (making sure to keep it level) and put the end of the tape to the pin deck. Easier for me to keep the tape straight.. TETO

Flat gutters depths are measured from a point even with the back row of spots only. (7,8,9,10)

I believe the first question was answered well enough...if not I can get some pics of measuring flat gutter depths.

The second question can be answered easily. You will however need to make a couple of tools. You will need a piece of string about 4 feet long. I also use a 1/2 X 13 hex nut as a weight. Tie the string to the nut. Get a 4' level and place marks at 14 11/16" and 16 15/16" from the end of the level. Put the string over the top of the deck lift shaft being sure the nut is hanging over the back of the deck lift shaft. Allow the nut to hang just above the pit carpet and directly behind the 10 pin spot. Place the level on the lane over the 10 spot...being sure to put the two marks you placed on the level so they straddle the spot. The end of the level should extend straight back toward the elevator. You now have a measuring "stick" where the end is exactly 15 13/16" from the middle of the 7-10 line. The string is letting you know where the back of the deck lift shaft is located. Now your job will be to move the machine forward or rearward so the string just touches the end of the level.





When you go to measure the 7 pin side, you will need to "thread" the string so that it does not touch any of the parts on the back of the deck. The scissor spring and linkage can get in the way.
