Hi,

I'm new to X-Cell machines and have a gasser that I picked up this summer. I was having vibration problems and found the blades going out of track when adding collective.

I have checked everything and main and tail shaft don't have any runout and I have the fan and clutch also running true.

I've decided to replace the head and associated parts as I found some wear and some things that were a little questionable. The spindle in it was from what I understand a Bergen with a black ring around the center of it. According to the instructions for the machine the spindle should have a piece of fuel tubing on it. Which is the better way to go?

It also looks like the damping shims (0329) are all distorted so I guess I should get a new pack of them also.

Any other tips on head assembly?
