Badger Meter Compound Series - Manual (Page 20)

Reinstalling the Cover Assembly
Badger Meter recommends that a new O-ring be used after each teardown and reassembly of the cover assembly To assure
a tight seal, make sure O-ring is positioned correctly on the housing and that the O-ring and cover assembly are clean and
free of dirt or residual traces of old O-ring material If necessary, use silicone grease to help retain the O-ring and to serve as a
lubricant in reassembling it to the housing
Cover bolts should be tightened in a crisscross pattern similar to Turbo head bolts Torque 2" and 3" cover assembly bolts to
16…18 ft-lb Torque the bolts for the 4" and 6" cover assemblies to 35…40 ft-lb
