Sylvian,
Your OP looks like you are looking for an alternate air door spring, and the Cleveland one is for the oil access door. If the spring is too strong, it might not allow the door to function for alternate air. Might want to check on it.

Default Contact James Aircraft North

Sylvain, I lost the springs on my Mk3 at some point in the build process. I emailed Will James asking for the part number and he just sent me two new springs. You might send him a quick email.

Hi Darin,

I have those little springs with the kit but I don't know if there are right for an automatic alternate air door utilisation ? Can you tell me how you installed them ?
If you have a pic...

Default No pictures

Hi Sylvain, I don't have any pictures but I did do it similar to the instructions. Basically I cut the center eyelet out of the hinge and then slid the hinge pin through the springs. They did take some "winding" to get them to clock properly and hold the door shut with a good amount of pressure.

Darin,

Did you install a control cable or only an "automatic" alternate air door ?
There is no instructions about the springs in the James Aircraft instructions.

I will take some pics tomorrow to have your help because I don't manage to install those springs...

Darin,

Take a look on this picture. The alternate air door need a spring for close hinge.
and the spring received with the kit are spring for open hinge.

So I don't understand how you are able to install it as a close spring.
