Locking Steel Annulus

The Annulus is a socket that allows the hydraulic puller to be anchored into the Pulley Base Assembly. It is fastened to the Pulley Base Assembly with three bolts (TT-FSNR-DA4000C), and the Nose (TT-NOSE-LSFB) can be locked in place with a pair of Pins (TTA-NULA-LPASM). They are plated with yellow zinc chromate for added corrosion and wear resistance.
