22.  Reinstall the top plate as shown in Figure 

15.

17.  Make sure the copper plug is still inside of 

the slide block.

18.  With the help of an assistant, raise the taper 

attachment underneath the slide block, so 

the pivot pin slides into the pin bore in the 

slide block (see Figure 12).

19.  With your assistant aligning the taper 

attachment mounting holes, use an 8mm 

hex wrench to tighten the four mounting cap 

screws and secure the taper attachment to 

the carriage face (see Figure 12).

20.  Using a 4mm hex wrench, snug the slide 

block set screw so the copper plug is slightly 

preloaded against the pivot pin (see Figure 

13).

or arm clevis at this time.
