300 Cbi Tail Rotor Grease


Recommended Posts

I am doing a 25 hour on a Schweizer 300 CBI (I am a pilot not an AME). It has 375 hours and no accidents. I can't get any grease into the tail rotor grease fitting. Its a flat portal that is filled by a needle/tapered adapter. It is blocked and I don't know if the Zerk-type fitting is working. The ball is not at the opening.

 

Has anybody seen this? Any solutions?

 

Does this fitting has a name?

 

Thank you.

It usually means the ball and spring are jammed in the end of the Zerk. You need to put a new one in. If they are the same as the ones you see on Bell machines the p/n is NAS516-1A (If I remember correctly).

I had this happen to me while greasing a 205 scissor link. The only thing is that the spring came out of the fitting and ended up in the grease. I had to clean out the grease and look carefully for the spring in the bearing area. Make sure your fitting still has the spring inside.

 

Good call. :up:

I am not familiar with the 300 t/r, but on the 206, there was an AD issued because a seal was installed backwards, and the only way to tell when installed on the aircraft is that you couldn't get grease into it.

Have an AME licenced on type look at it to confirm it is just a spring issue on the fitting.
