This is only my second build. I have installed the main shaft with the spacer on the top bearing block and main gear in and I've noticed that I still have play when I lift up on the head block.
I do have an extra spacer, but it does not show two being installed. What can I do to fix this?

I did have this same problem when I built an NX4 and found out that I had a bearing block upside down. But these look identical.

Thanks

You should be able to find the correct washer to use in the spare parts bag, but if not no harm in using two if necessary. Just make sure it isn't too tight putting the bolt through gears.

If you are using a FB head, you are probably using the wrong main shaft. The FB main shaft uses an adjustable collar.

It was a combo kit with everything but the battery and receiver. I'll look again but I don't believe the collar is adjustable on this one.

At the top you said it is FB. I assumed it was an older version. What version 500 is it?

Shim as required. If it takes both spacers, fine.
