Installing center plate

1.

Grease the ends of the shafts with Mobilgrease

XHP™ 222, paying special attention to the splines on the drive

shaft and the step corner after the splines. This is to ensure the shaft seals in the center plate do not hang up on
the corners of each step on the shafts.

2.

Ensure that the pump chamber O-ring is properly seated in its groove, Figure 1.

3.

Align the bearing holes of the center plate with the drive shafts and carefully lower the center plate over the shafts
until it contacts the pump chamber, Figures 2 and 3. When pushing the center plate over the drive shafts, apply
even and steady pressure to ensure you do not damage the shaft seals during installation. Be sure that the
alignment pins of the center plate and pump chamber are properly engaged.
