Dzude Posted May 30, 2008 Report Share Posted May 30, 2008 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.

Elvis Posted May 30, 2008 Report Share Posted May 30, 2008 I guess I must have been lucky, in the 6 years I worked on 205s (James Bay & the Labrador coast) I only changed one starter seal. I remember it well NBR2 at night in the pouring rain. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
Elvis Posted June 1, 2008 Report Share Posted June 1, 2008 I hope you have the engine manufacturer's permission to install a modified seal. Quote Link to comment Share on other sites More sharing options...
arctic_front Posted June 2, 2008 Report Share Posted June 2, 2008 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.

eunecte Posted April 1, 2009 Report Share Posted April 1, 2009 Some one can tell me how long those carbon seal(3500$) last... cause if they make more than 800Hrs it's more cost efficient then the lip seal (1000$)... Quote Link to comment Share on other sites More sharing options...
scottyp1973 Posted April 1, 2009 Report Share Posted April 1, 2009 if your new seal leaks, chances are the starter gear or fore/aft support bearings are worn, the vibration will cause the seal lip to burn out very rapidly. expensive fix. but a fist ful of new seals will never solve the problem.
