Vacuum Pump Repair - ZR-1 Net Registry Forums

I can't resist a challenge on repairing things.
Back about 12yrs ago my secondary vacuum pump failed.
I took it apart and replaced the diaphragm in it.
The I used epoxy to hold the cover for the diaphragm in place
and avoid leaks.
Well 12yrs later it fails again. This time I fashioned a bracket that
fits over the vacuum pump and holds the diaphragm in place.
This way I can get back in and put a new diaphragm in without having to chip away at the glue holding the cover for the diaphragm in.

Not the prettiest thing in the world but oh so functional.

In the picture of the diaphragm you can see the split in the rubber right at the point where the metal washer touches it when it's in the pump.

Mines in a box in the garage along with the rest of the secondary junk. I wont break if it isn't installed.

Hi Scott,

Nice pix, BTW, is that a TEK scope in the background ?

Cheers,

One of those I was responsible for.
