I’m not. I’m just saying they’re easy to repair. When you replaced the seals did you hone & deburr the cylinder? Have you checked the pump for an internal leak?

Hi Danny:

Didn't know you were in the cylinder repair business!! It is the actuating cylinder that is giving the problem. I have rebuilt it twice and it lasts for a while and then starts to leak again across the piston. No sign of any other leaks anywhere and we have blanked off all the other cylinders and the pump still cycles. So it must be the cylinder.

I have actually sold the plane to my flying buddy who did all the initial flight testing for me but am helping him with the maintenance now and again

Regards

Ian

Ian,
Are you looking for an actuating (gear up & down) cylinder or an oleo suspension (Ong debonger type) cylinder? I have actuating cylinders that can be rebuilt and I’ll even do it for you. I have no oleo struts but if yours need to be rebuilt I’m sure it can’t be difficult.

Does any one have a spare main gear cylinder for sale?

Does anyone know where they can be repaired successfully or failing that where new ones can be bought?
