🔍 Key Concepts

• Function of the locking ring and bowl cover alignment marks as an indicator of correct bowl stack height and thread condition • How changes in stack height (disks present/absent or misordered) would affect how far the cover can be drawn down • Whether thread wear would let the locking ring travel farther for the same clamping force

💭 Think About

• If you leave out disks or misassemble them, does the bowl cover end up sitting higher or lower, and would that make the locking ring stop sooner or later? • Which of the listed problems would permanently allow the locking ring to screw down farther than normal, even if all parts were correctly counted and in place? • Think about what the manufacturer’s alignment mark is mainly intended to reveal: an assembly error inside the bowl, or gradual dimensional change of the locking components?

✅ Before You Answer

• Verify which conditions change the effective height of the bowl stack under the cover (missing/misordered disks vs wrong paring device order). • Consider whether paring device order actually changes the clamping distance of the bowl cover and locking ring, or mainly affects flow paths. • Ask: which option would cause a progressive increase in how far the locking ring passes the mark over time, even if you assemble it carefully each time?
