<= p class=3DMsoNormal> 

Dear subscrib= ers,

 

When my starter died last month away from home the local aircraft me= chanic convinced me to put a sky-tec starter C24ST5 in my 4P. His arguments= were availability reduced weight and state of the art design.

 

It had an = external solenoid on it which interfered initially with my AC-compressor. B= ut it has flange that can be rotated and I was able to fit it in (but it re= quired a longer power cable from my solenoid plate).

 

When I put it on the= first time the locating diameter fit felt kind of sloppy to me and the sea= ling O-ring looked very tiny. After I was home I noticed an oil leak (no dr= ops on the ground but I can see that the engine looked wet on the rear side= ).

 

I pulled this starter twice now (a lot of fun!) and the last time I ev= en put very thin film of gasket maker on the sealing diameter and on the fl= ange ( I really made sure that all surfaces are clean and without damage). = I still have an oil leak!!!

 <= /o:p>

Question: is anybody using this sky-tec-start= er? What experience do you have with it?

 

It seems to me that the locating= diameter is a too sloppy fit and this o-ring on the locating diameter look= s really tiny. Since the flange can be rotated on the starter the flange ca= nnot be used as a sealing surface anymore. Once the oil passes the o-ring t= here is nothing that stops it.

&nbs= p;

I am thinking about buying the original st= arter again.

 

Thanks for your input
