Epilogue to my tachometer troubles...

After chasing wires and cleaning connections, I finally disassembled & thoroughly cleaned my hitherto-exposed cannon plug on the Chinese tach generator in the engine compartment. 

Redressing the wire run and c.plug with oil resistant tape, it's run like a champ for the last 4 flights.

Fwd and aft gauges in perfect synch.

So, I'm calling the system fixed.

Thx for all the inputs-

 If you have the later ENGINE mounted Tach. gen. re-greasing of the bearings  would be likely a 300-500 hr. unit  overhaul  function. 



   



  If  you have the original FIREWALL mounted, cable driven unit, just  throw it  away and get the later one from Doug Sapp.



   



  Cheers;

  Ok-  Any experiences(s) with a good lube/grease for the tach gen bearings?  Justin

Morning all,      

 

      

Fast question re: the Housai's tiny tach generator for prop    rpm indication.

      

 

      

In the midst of my cond insp, and the RPA checklist notes    the tach gen should be removed and "disassembled and bearings repacked with    grease."

      

 

      

I've yet to disassemble one.

      

Where are these bearings (ie- how get to    them)?

      

What grease have y'all successfully    used?

      

Tach gen maint tips & thoughts much    appreciated...
