STEP 22
Locate the two Front Rail Block Captive Allen head screws (one on the left side and one on the right side of the
DE) which hold the Front Rail Block to the DE Rails (see Figure 20).
Loosen these screws using the 5mm Hex Torque Tool PN 74Y0986 (shipped in the Hand Tool Kit). Rotate the 4
screws counterclockwise until they are free from the DE.

STEP 23
Determine if the Front Rail Blocks will interfere with any cables (which will damage the cables). If you are sure
they will not interfere, you can leave them attached.
If they will interfere with any cables, remove the Front Rail Blocks by loosening the four Front Rail Block Hex
Screws (two on the left side, and two on the right side of the DE) (see Figure 21) using the following tools:
•
Ratchet h handle P/N 6428240 (shipped in the Hand Tool Kit)
•
Extension (18”) P/N 46K2707 (shipped in the Hand Tool Kit)
•
10 mm Socket P/N 02F3582 (shipped in the Hand Tool Kit)
If you have removed the Front Rail Blocks, store the blocks and hex screws for reinstalling later.
