Mike,

   Thanks a lot for quick response and for the excellent photos\ information, that is exactly what I needed! It looks like I should be able to handle this work without even pulling the transmission.  Knowing the seal size could be helpful if I end up having to match it up but I will first try to source a seal kit for this transmission.

Best,

Hi James,

You just need to replace the lip seal (sorry I don't know the size - can check). I did this by removing the shifting arm shaft. Hopefully the attached photos help. I used some gasket maker/RTV when mounting it back on the gearbox.

Hello,
   Recently the Hurth HBW-250-3R transmission on my Maramu has developed a slight transmission oil leak.  The leak is clearly located in the shifting arm shaft, the output shaft seal is dry.  
There does not seem to be any binding in the shift linkage since when in either forward or reverse the shift arm can be easily moved a very slight amount.  Has anyone else had to deal with 
this leak issue and if so what parts/seals were needed?  I am currently cruising the Southern coast of Turkey and anticipate soon moving up the Western coastline.  Can anyone recommend 
someone that could supply parts or perform service on this transmission in Turkey?

Thanks,
