Does anyone operates their T53 with new starter carbon seal? I would like to know if it's better than the lip seal. I think the kit worth 3000$. Also if you have any advice to keep the lip seal from leaking, feel free to discuss. Best I've ever seen not leaking on a 205 was 200 hrs.

Thanks, Dzude.

I just changed one the other night. Lots of fun.... There are two ways to make them stop leaking. The first one is to install a speedy seal to the runner. Its a thin sleeve that is pressed on the runner. I believe the sleeves can be bought at places like Napa etc. This cannot be done in the field but some operators are installing them before they send out the runner to the field.

 

The second way which can be done in the field is to take the spring off the seal and unscrew it where the ends are put together. Cut off approx. 1/3 to 1/2 of an inch. When you screw the ends back together make sure you pre twist it ccw so when it is screwed together it does not have a tendancy to untwist. This method works excellent. I have not had one leak after doing this. You can play around with how much you cut off but if you get it too tight I think it could run a groove in the runner and start to leak. I hope this is strait forward. Let me know if not.....I haven't heard from any one about the mag seal yet. I am very curious.

There is a new temporary amendment in the T53 maintenance manual regarding the carbon seals.... it also asks you to measure the inner pressure of the Acc. gearbox. too much pressure will make them leak... so says the amendment. I have never done the check, but it seems easy enough to do. 1.5 PSIG is what they call for, or less.

 

Anybody try this? I just read it yesterday.
