Dillon Precision index detent ball spring for RL 550, XL 650 and XL 750

Dillon Precision index detent ball spring

The index detent ball spring is the spring that pushes the indexing ball against the shellplate platform. Its pressure determines how firmly the platform stops at the station, and therefore the repeatability of the alignment between the cartridge case and the die.

Part number 13997 appears as "Index Detent Ball Spring" in the platform assembly of the RL 550 (page 63 of the manual), the XL 650 (page 52), and the XL 750 (page 61). It works in tandem with the 13891 ball, which Dillon lists on the same exploded view and which must be ordered separately.

Main features

• Indexing ball tension spring
• Original Dillon Precision replacement part
• Listed for RL 550, XL 650, and XL 750

Recommended use

Replacing the spring when shellplate indexing becomes weak or inconsistent on Dillon RL 550, XL 650, and XL 750 presses. The indexing ball, Dillon code 13891, is not included.
