Replacing the Liner in the Flex-I-Liner Pump
On occasion, it will be necessary to replace a worn liner. It is imperative that this member be correctly installed to insure maximum longevity of the liner and satisfactory future perfor- mance and operation of the pump.
In Figure A-4, the bracket shown in the top photo is that for close-coupled models. The bracket in the other photos is for pedestal mount models. Other components remain basically the same for all Vanton Flex-I-Liner pumps.
To assemble:
Wipe Vanton Silicone oil on the ID of the liner before assembling.
Grasp liner and block. Push the liner through the back side of the block. Using your finger, wipe the inside diameter of the liner thoroughly with Vanton Silicone oil. Also apply some of this oil to the rotor.
The object is to push the liner over the rotor and metal boss (see arrow) of the back plate.
As you can see from the photograph, the liner has now seated itself over both the rotor and metal boss of the back plate and the flanges of the liner have seated in the recess provided.
Once the liner is in place in the proper recess, apply pressure to the block until the block seats over the guide pins. Now install the expansion ring and cover plate.

Note: When tightening bolts, apply even pressure. Tighten the bolts in a sequence of: upper left — lower right — lower left — upper right.
