Hi, I just bought a cylinder leakage tester the other day and went outside to test out my cylinders last night.
The instructions that came with it are not very clear at all and Im worried that the guages that are on this thing are not working correctly.
Can someone walk me through how to use it?
This model has 2 guages and a regulator. The input pressure is supposed to be anywhere from 10-100 psi (no higher). The first guage reads the psi of what? and the 2nd guage (on the outlet side) reads a % of leak-down with red, yellow, green, and "set" ranges marked on it.
How do I calibrate or 0-it-out?...I couldnt get the pressue on it turned up past ~20psi without the leakage guage going PAST 0% leakage (above where the guage reads)...shouldnt this be up around 80-90psi for a normal cylinder without problems?
Could the % leakage guage be defective?
When its all set correctly what does the PSI guage tell me and/or what should it be set to?
Thanks for any help in advance!

The first guage is showing how much pressure it is putting into the cylinder. The second guage is showing how much leakage the cylinder has. Regardles of how the second guage is marked...psi or %...look at it the same as a psi guage. Now to calibrate it... do not hook up outlet hose. Hook up the air hose and crank the regulator up to 100 psi on the first guage ( there should not be any air flowing at this time ). the second guage should show 100 psi or 0% leakage depending on how it is marked..But BOTH needles show look the same on the face of the guage. if not then one guage is bad. If thats all good, now put outlet hose into cyl with piston at tdc..hook up inlet hose, crank up to 100 psi on first guage..take reading on second guage..lets say it reads 80 spi or 20%..that is 20% leakage on that clyinder. 100psi =0%,90psi = 10% 80 psi =20%, see the pattern here??

hmm...when I tried that (ill try again tonight to be sure) I think the most I could get on the first gauge was about 20psi before the 2nd gauge (%) was at 0%!...any higher and the 2nd gauge would read past the max!

the regulator should regulate the pressure in no matter what pressure is hooked up, but you probably need atleast 30psi.

On my LD tester(Kawl equipment) you start with the first piston at TDC you
will need to hold the clutch somehow so the motor won't spin when you apply
pressure(make sure it's at TDC.. important)spin tester into plug hole attach
shop air hose turn regulator slowly up to 100psi on the first gauge when your
at 100psi look at the second gauge and see what the psi is, it should be as
close as possible to 100psi on the first gauge.
you don't want to be no more than 10% off
(so you need to be at least 90psi on the second gauge),
get your reading then turn down the regulator on the tester(to relieve pres.)
then remove and do the next cyl. then so on..
just make shure every cyl. you check is at TDC or the reading will be wrong.
thats how it's done with my tester anyway.

sounds like you have a bad guage...now which one..
