Can anyone help with front prop shaft seal on my M14p please.



During gyroscopic maneuvers  my YAK55m is spewing oil everywhere.

We have replaced pretty much every O ring and gasket on the engine, the oil looks to be coming from the propshaft exit on the front of engine.



I have an engineer who has a suitable tool for refitting the shaft and seal.



We are about to take the prop/hub off, and remove the gearbox.



It’s my understanding the gearbox has to be disassembled to gain access to the front bearing and seal.



What else should we look to replace or service whilst we have it all apart.

Plus who can supply the seal, and is it prudent to replace the bearings as well ?

Have experienced the same thing a few years ago. 



Do as you said. Remove the prop. Remove the gear case. Ship the gear case to Jill at M-14P.com. They have the nose case prop shaft seals in stock and will remove the oil seal and install an new seal all in good time.



And your oil leak problem will be solved.

But, quite expensive to ship an entire gearbox to and from New Zealand!
