1f) Reinstall the CRT gasket into the gasket channel of the coupler. Confirm the placement of the CRT, C-
element lens, and vent plug gaskets.
2f) Place the CRT onto the coupler with the high voltage anode lead positioned as marked in step 10b of
procedure B.
3f) Carefully position the CRT onto the coupler, using the outline defined in step 6b of procedure B as a
reference.
4f) Start the CRT mounting ear screws but do not tighten them.
5f) Tighten the CRT mounting ear screws in a star pattern (like tightening lug nuts on the wheel of a car).
Make sure the CRT does not shift position from the outline defined in step 6b.
Caution: Do not over tighten the CRT ear screws.
Note: The CRT mounting ear screws are not used on some assemblies.
6f) Install the CRT mounting bracket and start the four CRT mounting bracket bolts with springs.
7f) Tighten the bolts in a star pattern.
8f) Lay the CRT assembly on its side with the plug pointing up.
9f) Remove the plug.
10f) Using the PTV coupling fluid bottle with the cone top, refill the coupler with fluid through the drain access
hole. Completely fill the coupler chamber so the fluid is level with the top of the coupler at the plug. Wipe
any excess fluid from around the coupler.
11f) Reinstall the plug and check for any fluid leaks.
12f) Install the repaired CRT/optical block assembly into the PTV and perform any necessary adjustments. |
