Status: offline 		This may be a really dumb question, but I''ve never had to do it before.....

I have a SJ 3000 and it''s developed a slow drip at high RPM''s. I want to take off the front cover to see if it''s just a loose fitting, but can''t for the life of me figure out how to do it!!!

Please help.

Thanks!
Mark

i had the same exact problem.... a loose festo fitting.
Simply remove the four lateral screws and gently pull off the cover.

Assuming that you have the older "Spun" front cover, remove the 4 socket head screws and slide the cover off.

The leak is likely a festo fitting or old tubing that needs to be replaced.

Start with the TUBING repalcement first.

Status: offline 		Thanks guys for the input. As it turns out, the front cover screws off in a reverse thread fashion. Is this the new way or do I have an older version 3000?

After further inspection, I found that both Festo elbows were leaking . I tried replacing all the 4mm tubing under the cover and using the same elbows, but that didn't fix the problem.

Right now I have just the 4mm tubing coming from the brass tubes (safety wired of course) going to the Festo "Y" then to the solenoid. I left enough slack in the tubing to allow for about about a 1/2" radius bend so they wouldn't kink. Is there any problem leaving it this way? Should I open it all back up and put new 4mm elbows in there before permanently installing it in the airframe?

Thanks in advance!
Mark
