Tools Required

Mobil SHC 460 Grease
Medium-strength thread-lock compound

Step 1

Remove all tools from the tool changer. Put wooden blocks on the table. Put a bottle jack on the wooden blocks.

Jog the table below the center of the carousel plate.

Support the carousel plate with the bottle jack.

Push POWER OFF.

Remove the (6) SHCS from the carousel plate. With a second person remove the carousel plate.

Step 2

Use your hand to push the station door [1] fully in to make sure it moves freely. If it does not move freely, clean the chips from the door and the door track.

Use a straightedge on the extractor fork [2] to see if it is bent.

Remove the screws [3] that attach the damaged fork assembly to the carousel plate. Remove the assembly as shown. Replace all damaged parts.

Apply a medium-strength thread-lock compound (for example, blue Loctite®) to the threads on the fork assembly screws [3]. Apply Mobil SHC 460 grease to the thru-holes of the replacement assembly.

Install the replacement assembly. Make sure that the beveled side of the washer [4] is against the extractor key (BT, shown) or the fork bushing (CT). Torque the screws to 7 ft-lb (9.5 Nm).

Step 3

Put a piece of tape [1] on the carousel at pocket 1. Remove the pocket number ring [2].

Remove the sliding panel cover [3], compression spring [4], rivet [5], and sliding panel [6]. Replace all damaged parts. Clean all debris from the pocket.

Apply Mobil SHC-460 grease to the new compression spring. Put the 3/32" rivet into the end of the compression spring. Install the new compression spring [4] and new sliding panel [6]. Install the new sliding panel cover [7] while you push the end of the spring [8] under the panel.

Torque the (2) 10-32 SHCS [9] to 20 in-lb (2.26 Nm).

Apply medium-strength thread-lock compound (for example, blue Loctite®) to the (2) 10-32 flat head cap screws (FHCS) [10]. Install the (2) FHCS [10] and torque to 20 in-lb (2.26 Nm). Make sure the sliding panel [6] moves freely.

Install the pocket number ring [2]. Make sure the number 1 on the number ring aligns with the tape [1] on pocket 1 of the umbrella tool changer.
