INSTALLATION, OPERATION AND MAINTENANCE MANUAL
MODEL
RB
WEIR GATES
MAINTENANCE: SEAL REPLACEMENT
(8”X8” TO 48”X48”)
Step 1: From the closed position unscrew the nuts and remove the washers of the lateral anchor
bolts (items 1 and 2).
Step 2: Unscrew bolts (item 3) that hold together the frame guides (item 4), UHMWPE guides
(item 5) and frame. Proceed with caution, as major components of the gate are no longer se-
cured.
Step 3: Remove frame guides (item 4), UHMWPE guides (item 5), slide (item 7), yoke (item 6)
and stem (item 8) as one unit.
Step 4: Unscrew bolts (items 9) and remove retainers (items 10 and 11).
Step 5: Remove seal (item 12) and replace it by the new seal.
Note 1: After installing the new seal, apply grease on it to ease operation.
Reassembly:
Follow Steps 5 to 1.
Note: To reassemble in Step 3, first place one of the UHWMPE guides (item 5) on the anchor
bolt rods. Next, take the yoke, stem, slide and frame guides as one unit, and attach the other
UHWMPE guide onto it. Finally, mate the whole unit to the previously positioned UHWMPE
guide.
