The PackRyt® should be installed in the order that it is packaged from the factory -  starting with the bearing unless otherwise instructed. Please note the order and direction before opening packaging. See Example Photo Below.

PackRyt bearing how it comes from the factory

Remove all old packing, lantern ring, etc. and thoroughly clean the shaft and stuffing box.
Make sure there are no solids present in the sealing area. 

Disconnect any discharge or water “out” flush lines and plug the hole, leaving only the “in” line. 

Measure the depth of the stuffing box. Measure the length of the PackRyt® bearing. Subtract the bearing value from the stuffing box value. 

This value will be needed to determine that the bearing is properly seated in the stuffing box.

Step 2.

The PackRyt® kit should be installed in the order and direction that it was packaged from the factory starting with the bearing unless otherwise instructed. 

 Split the bearing and re-assemble over the shaft, making sure the extraction holes are facing you/atmosphere as you slide the bearing in.

Troubleshoot tip: If the bearing will not pilot, use a Porto-Power™ or other device to center the shaft so that the bearing slides into the stuffing box. If significant bore corrosion prevents installation, you may lightly and evenly sand the outside diameter of the bearing with fine crocus cloth to very slightly reduce the outside diameter and aid in installation. Don’t remove the Porto-Power™ until all parts including the packing are installed.

 Make sure the bearing is fully seated in the bottom of the box. Measure the depth of the stuffing box to the installed bearing and compare this measurement with that from STEP 1. The values should be no more than+/- 0.003” confirming proper placement. If it’s more than +/- 0.003” then remove the bearing and check that the stuffing box is clean and clear from solids.

NOTE: For cases where multi-piece bearings, BLR (PackRyt® bearing with a lantern ring) in combination with a BRG (PackRyt® bearing without a lantern ring), have linear grooves align the pins on nose of BLR with holes on end of BRG in order to align linear grooves correctly.
