The Guardex™ FBA (flywheel-blind assembly) was designed in response to engineers that required a torsionally soft drive system with "plug in" capability. This flywheel coupling consists of a steel flywheel flange (zinc clear chromate protected), heat treated steel hub (can be splined or bored/keyed), rubber vibration dampers and specially designed fasteners (no nuts required!).

NOTE!!
The end-user is required to use a lithium-based grease on pump spline and coupling at installation. Guardian recommends Texaco1912 or equivalent. |
