Before you can remove the four-part hook block, you need to ground the hook block using the normal procedure. Boom down until the hook is resting on the ground. Never winch down once the hook block is supported.

Once the hook block is grounded, I need to remove the front and rear hook block wire rope guide plates. Using a 17 mm wrench, remove the eight bolts securing the two plates. Each bolt has two washers.

After I've removed the wire rope guide plates, I need to dismount the anti-two-block weight while leaving it connected to the switch. To dismount the anti-two-block weight, I'm going to use a 5 mm hex key and remove the roller and pin from the weight to free the wire rope. Now the anti-two-block weight is freed from the wire rope while still being connected to the switch.

Once you've dismounted the anti-two-block weight, you need to remove the wire rope socket from its tab. Using a 19 mm wrench, remove the wire rope socket pin bolt and washer, then pull the wire rope socket pin to dismount the wire rope socket from the boom tip.

Once the wire rope socket is dismounted from the boom tip, unreeve the left-hand sheave of the hook block by pulling the dismounted socket through the block.

Next, we need to pull the dismounted wire rope socket off of the left boom tip sheave. To do that, we need to unfasten the wire rope guide plate. There are two pins holding it in place, and they're both safety-clipped. On the left side of the boom tip you'll find a cotter pin securing the guide plate fastening pin. Once you've pulled the cotter pin on the right side of the boom tip, pull out the pin — you only need to pull it about halfway to release the left-hand guide. You need to reach inside of the boom tip, over the left-hand boom tip wire rope guide, and pull the cotter pin.

Then, from the left-hand boom tip wire rope guide plate, you can rotate the plate to free the wire rope off of the left-hand boom tip sheave. You'll have to rotate the plate back and forth to provide the clearance so that you can unreeve the wire rope.

Once the wire rope is off the left-hand boom tip sheave, you can pull the dismounted wire rope socket through the boom tip. Then unreeve the right-hand boom tip sheave by pulling the dismounted wire rope socket completely out of the hook block.

When you've completely dismounted and unreeved the four-part hook block, the wire rope should be coming off the wire rope drum and over the right-hand boom tip sheave. If that's true, you're ready to remount the A2B weight onto the wire rope. Then use a 5 mm hex key to tighten. Our anti-two-block weight is connected, and we still have our dismounted wire rope socket.

I need to unground the socket and position it above the stored one-part hook. Do not command a winch up until the wire rope socket is off the ground.

Use the wire rope socket pin to mount the wire rope socket onto the top of the dismounted hook block, then use the 19 mm bolt and washer to secure the pin. Once the wire rope socket is properly connected, maneuver the upper works to pull the hook block out of stowage.

Once you have the one-part hook block attached, push the hook block function key on your LMI, then change the indicated hook block from four to one. Push the Enter key to lock in your selection, and now your LMI indicates a one-part hook block has been attached.
