28. Install the shaft assembly to the rotary table ensuring the torsion

springs properly engage the rotary table as shown. Secure the left

bearing block to the rotary table using the two 10 - 32 x 7/8 cap screws.

Align the right bearing block squarely to the rotary table then secure it

in place using the two 10 - 32 x 7/8 cap screws.

29. Assemble the collar clamp and shaft spacer to the left end of the shaft

so the retaining ring and shaft spacer are located firmly against their

respective bearing blocks. There should be no lateral movement of the

shaft.

Squaring the bearing blocks to the rotary table provides a coarse

adjustment that will be finely adjusted at the board handling final set up

procedure.

30. Install the two tooling pin housings to the tooling plate using the four 6

- 32 x 3/8 button head screws.

Location of the tooling pin housings on the tooling plate will be determined

at the final set up procedure.

31. Attach the two tooling pins to the two tooling arms using the two 5 -

40 x 1/4 cap screws.

32. Install the two tooling pin arm assemblies to the tooling housings

using the two 6 - 32 x 3/16 button head screws and washers.

33. If necessary, install the two safety labels and the front label to the

rotary table at the positions shown.

Two different size tooling pins are supplied with the board handling

system. The standard tooling pin, UIC # 45810401, is supplied

assembled to the locators. The standard tooling pin is used for datum

holes .110 inch (2,8mm) to .187 inch (4,75mm) in diameter. The large

tooling pin, UIC # 45810402, is supplied in a bag attached to the

workboard holder. The large tooling pin is used for datum holes .188

inch (4,76mm) to .250 inch (6,35mm) in diameter.
