SM102 AIR LEAK

Hi guys
There seems to be an airleak as we can hear the sound on the pneumatic valve. Took me awhile and my phone wet with oil just to see the model because we're afraid to open it, might cause more leak. We're hearing it on this area. I already found the part on ebay but wanted to check maybe theres an alternative solution

 

Use a pliers to pinch off one of the 6mm air line at the valve. If air stops leaking, your problem may well be at the piston it controls, not at the valve. Depending on whether it's for the ductor, impression or dampening, a seal may be bad in one of those pistons.

 

Junker is on the right track I just replaced a couple of the cylinder s seems like I will have to replace more while I'm here Doe's anyone know if ineeI to remove the coating tray on this press 102 to replace the super blue net not sure any help would be appreciated thank you. Spike
