Dear group members,
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. |

I think Mark Thorson forgot to include a smiley face at the end of his
post. Introducing pepper, or any other type of solid into a hydraulic
system is an exceptionally bad idea. Don't do it!<br>
<br>
I suggest that you continue your search for a service manual. If your
search is unsuccessful, then go ahead and try to fix the leak on your
own. Hydraulic systems are usually relatively simple and easy to
service. Just take your time when disassembling your system. Take
careful notes and digital photographs of the process. Try to keep
everything clean and avoid introducing contamination into the system.
The most likely cause of the leak is a torn gasket or a worn out
o-ring. O-rings can be purchased at most industrial supply retailer.
You can also purchase gasket materials and make your own replacement
gaskets.<br>
<br>
Good luck!<br>
