pressure hole and two oblong holes on the inlet side.
Position the wear plate in the cover with the bronze
side facing up (towards gears) and the 0.625”
pressure hole located over the circular holes in the
cover. (fig. C4352)
12. Line up the cover assembly with the shaft
journals and dowel pins (fig. C4351). Lightly tap the
back of the cover until dowel pins are completely
engaged. Check the seal making sure it is seated
properly with no foreign material pinched between
the surfaces.
13. Place the screws in the cover holes and turn until
the treads engage. Use care so that cross threading
does not occur.
