My company has an Instron 1331 servo hydraulic system which no longer
has the schematics or manuals for the hydraulic cylinder.
It has a small leak and I would like to learn if there is a gasket or
valve that I can replace.
Unfortunately, Instron no longer supports this equipment and they
don't have copies of the user manuals. I would need to get an Instron
technician to visit us, which is expensive.
Hence, I was hoping there is among you a user who has an Instron 1331
which I could ask for a copy of the maintenance manual or other manual
relating to the hydraulic system. I can keep operating the machine
with the leak, but would like to know the possible sources and repair
options before getting an Instron technician.
The cylinder has a model number of A411-108
Thank you
A teaspoon of finely ground black pepper
in that cylinder might plug that leak,
after a little while. Works for car
radiator leaks. Unlike a car water system,
the hydraulic fluid is not circulating, so
getting good particle distribution near
the leak may be a problem.
Black pepper is good because it's easily
available, doesn't rot or swell, and it
won't score metal surfaces. It also passes
through water pumps without a problem,
but that doesn't apply in your case.
