Installing Die In Model 816/817 Die Heads

The Semi-Automatic Die Head (Figure 13) for right hand threads requires four sets of dies to thread pipe ranging from 1/8″ through 2″. One set of dies is required for each of the following size ranges: (1/8″), (1/4″ and 3/8″), (1/2″ and 3/4″) and (1″ through 2″). Bolt threading requires a separate set of dies for each bolt size.

1. Depress handle and rotate so that cam plate rests

(Figure 13 – Model 816/817 Die Head) against the plunger knob (as shown).

2.Lay the die head down flat on a table or bench with the numbers facing up.

3.Pull up on the plunger knob and rotate the handle counter-clockwise all the way (to the left).

4.Select the correct dies for the size desired (size marked on the back end or face of the dies).

5.Numbers on the dies must correspond with those on the die head slots. Insert dies to the line marked on the dies – numbered edge up.

6.Rotate the handle clockwise (to the right) so that the plunger knob pops back down flush against the die head.

7.To set or adjust for desired size, loosen the screw for the desired size stop, move the block to the right to make it Under-Sized and to the left to make it Over- Sized. When setting blocks for new dies, start with the position block on the middle mark and adjust from there.

Checking Thread Length

(Figure 14)

1.Thread is cut to proper length when end of pipe is flush with edge of dies (Figure 14A).

2.Die Head is adjustable to obtain proper thread di- ameter. If possible, threads should be checked with a thread ring gage (Figure 14B). A proper thread is cut when end of pipe is plus or minus one turn of being flush with face of ring gage.
