INSTALLATION
Prepare RBS and selected Stationary Seal Face.
Spray shaft with layout fluid; scribethe shaft to mark the location ofthe back cover face (as shown).
Disassemble the pump accordingto the manufacturer’s instructions.
1 2 3
Determine the seal installationlength using the Rotary operatinglength(L3), the stationary operat-ing length from Dimensional Datatable provided and the backcover web thickness (measuredvalue from Step 4B). Seal Instal-lation Length = L3 + StationarySeat Length (S, K, KS or NSeat) +Back Cover Web Thickness(measured value).
Measure *Back Cover Web Thickness for use in installationlength calculation (Step 4A).
4A 4B
Confirm that length from scribedmark to step on shaft is equal to seal installation length (fromStep 4).
(Alternate Installation)For non-stepped shafts, measureback from scribed mark to locateand scribe the installation lengthon the shaft (see step 4).
Position lock collar (supplied bycustomer) at second scribedmark (installation length fromstep 6A). Tighten to shaft.
5 6B
Cover threads and keyway slotswith thin tape to prevent cutting/damaging the rubber bellows.
Lubricate shaft with soapy water.IMPORTANT: Do not use oil orgrease to lubricate shaft.
Push rotary bellows on to shaft;seat back of bellows unit againststep on shaft (or shaft collar).

Insert Stationary into gland. Slide gland/stationary assembly on to shaft.
Reinstall back cover; IMPORTANT:Check centering of housing: rotate the shaft by hand to ensurethat there is no contact betweenthe shaft and the stationary seat.
