Leak down tester.

[clemsonfor]

Anyone have a leak down tester to pressure test saws with, that they would want to sell,?? Looked on eBay ouch!

This seems like such a random tool I will never find it on CL or similar!

You only need a MightyVac pressure/vac pump, some tubing that fits the impulse nipple on the saw and a couple pieces of inner tube to block the intake/exhaust. The kits to vac/pressure test a saw with the ready made adapters are certainly expensive but most saws can be done without.

And no, you can't have mine.

Good tip!! You can even get those as loaners at auto parts stores . How long should it hold a vacume ? Forever?

Here's what I use

Just a gauge and some tubing

And to pull a vacuum or to pressurize I use this. I put a quick connect on the inlet and outlet so its simple to switch back and forth.

Just what I had hanging around.

How long should it hold a vacume ? Forever?

Ideally, yes, but that ain't happenin'.

Generally holding .5 bar (roughly 7 psi) of pressure and vacuum (test both ways!) for 30 seconds is acceptable.

You can get the vacuume pumps for $25 at Harbor freight.
I built DIY a leakdown tester with parts I had sitting arround.
Just google home made leakdown tester.
