For my front loader I have a Cessna valve, made in Great Britain.

Anybody have some knowledge of this type of valve? I am looking for a part list or any other information.

I have taken it off the tractor. Is it any good idea to open it and change o-rings etc., or should I just leave it unopened?

Do not know your valve specifically but have had some experience of similar valves.

Usually they are made as units and components are not interchangeable, if you need a new spool you need a new housing. If spool valve "O" rings leak it means the spools are worn and replacing the rings will not cure the problem.

I would feel that if you do not have problems at the moment, leave well alone.
