Refer to FIGURE 7-7, page 34. The outer races of the gear end bearings are clamped against the headplate
(F) by the bearing retaining screws or by bearing retainer plate (mechanical seal version) (B).
This is referred to as the "fixed end". The interference fit between the shaft and the bearing inner race (H)
keeps the shaft from moving axially. Adjustment is by movement of the shaft through the gear end bearing
inner race (H).
A. Check the total end clearance by adding the clearance between the impellers and the drive headplate to
the clearance between the impellers and the gear headplate.
