Name this part.

This was laying on top of my battery pack of my G700 today after I flew one flight. I also see some wear on my belt that is new.

Bearing shield from counter bearing?

[alexmit]

Looks like a bearing shield from one of the radial bearings in the one-way pulley assembly.

The first thing I noticed is that looks like your belt is riding way too high on the one-way pulley. It should ride in the center of the one-way pulley. This could be an artifact of the bad radial bearing though. This could also be from missing H0110-S Bushings or the one-way pulley not being shimmed properly to less than 0.4mm of play. Over shimming to where it is too tight can also kill the radial bearings.

Secondly, it looks like something has been rubbing the belt 2/3 about 2/3 the way up. My guess might be battery wires, which could be a catastrophe. I would suggest taking it apart and if you are able to see ball bearings in the races of anything in the secondary drive, that bearing would be bad. If it is a new helicopter, you should contact your dealer about replacing the part and they will determine if it was build/installation error.

It looks like it could be the SHCS on the main shaft making the mark on the belt?

SHCS?

Socket head cap screw, it's holding the collar on the main shaft. I've read that some are to long and hit the belt, it looks like it's inline with the wear mark on the belt. Just a thought.

I'm going to dig in and look as soon as I can. I don't know if the belt marks are from the battery out not, but I'll be checking that as well. I do know however, that those marks on the belt were not there before the flight. I've been watching the belt and how close it was to the frame, but it never appeared to actually touch it until today.

It looked very similar to what I was seeing, so I tore the motor off and had a look.

I guess I had my pinion set too low, and it rubbed against the bolts. Oh man that looks like such a newbie mistake. Here are my pictures.

The answer to the question of the topic posting is "Pulley Z22 (H0015-22-S)"!
