Disassembly and Reassembly of the Pulse Unit
(cont.)
14. Now, using the PTRF-1-1 and following the Fill and Draw sheet, apply the proper amount, press load to the
Rear Liner Plate, and tighten the Liner Casing Setter to the proper torque.
Note: Make sure that you use the
proper Press Cap when applying the press load to the Pulse Unit.
15. Once you are sure that the thread locker has set-up: Make sure that the Torque Adjuster is turned all the way
out counter-clockwise, fill the Rear Liner Plate with Pulstar oil, and insert the Piston stepped-end down into
the Rear Liner Plate. Put the Pulse Unit into the VC-101-2A Vacuum Fill Tank, making sure that the Pulstar
oil is about one-half of an inch below the oil fill hole on the Pulse Unit.
Note: The UAT-30D goes into the
Tank Anvil-side down.
16. Now, cycle the Vacuum Fill Tank. Note: The gauge on the tank should read 29 in.Hg. or above.
17. Now, pull the Pulse Unit out of the Vacuum Fill Tank. Tip the Pulse Unit on its side to remove the excess
oil from the top of the Pulse Unit so that it is level with the top of the oil fill hole. Following the Fill &
Draw sheet, remove the recommended cc’s of oil from the Pulse Unit and install the Oil Fill Plug.
Note:
Make sure that you pull up lightly on the plunger of the syringe as you put the needle into the Pulse Unit.
This will keep you from displacing the oil out of the Pulse Unit when you put the needle into the Pulse Unit.
18. Install the Purple Cushion onto the front of the Pulse Unit. Make sure that the Adjusting Spacer, Spring, and
Operating Rod are back in the Handle and install the Pulse Unit and Casing onto the Handle.
Note: The torque for the Front Casing is 16-24 Nm for the UAT-30D ~ UAT-80, 25-38 Nm for the UAT-90
~ UAT-130, and 13-19 Nm for the bolts on the UAT-200. Apply Loctite 243 to threads on the Casing
Connector.
19. You are now ready to test the tool.
