Compressor Mounting Question??

[tcb-1]

okay, the mechanical engineer in me is scratching my head.

I have a Viair 400C compressor. Looking at the hardware to mount it with make me a bit nervous. It mounts via a grommet/brass bushing in 4 places. The i.d. of the grommet is approx. .20", which leads me to believe I will use 3/16" hardware.

hummm, a bit skimpy for a 5 lbs piece of equipment that's usually vibrating during run time.

so my questions are:

has anyone "hard" mounted their compressor (take the grommets out? if so, any failures due to vibration?

anyone had issues with the bolts being TOO small?

just trying to rectify something before I figure out my installation and wondering if I need to drill larger mounting holes.

thanks gang!!
