A.1 MAXROY B PUMP ECC FIELD INSTALLA-
TION (RETROFIT) (FIGURE 19)
This section applies to field mounting the ECC on a
manually adjusted maxRoy pump. Refer to Figure
8 in manual 3390005000. Installing the ECC to a
maxRoy B pu mp re quires me chanically m ounting
the ECC and performing the ECC calibration pro-
cedures.
1. Remove n
ameplate (F

exposing th e keyway so cket in th e top of th e
knob. Adjust knob to 100% capacity setting.
2. Leave stroke locking handle (BK) loose.
3. Mount bracket onto pump housing 3 bolts and
lockwashers (Figure 19, 830 & 835).
4. Assemble dowel pin (855) (press fit) and brass
drive pin (845) (slip fit) into the link (850). Insert
the as sembled link into th e ca pacity control
knob keyway. The drive pin side of the link fits
into the slot in the top of the knob.
5. Loosely assemble the coupling (860) and cou-
pling nut (865). Assemble the coupling to th e
link. The drive pin of the link fit s into the cou-
pling slot.
