I'm putting together my E7 and I have 2 issues. First there is a slight amount of play between the main gear and the tail drive gear. There is no up and down play on the main shaft assembly itself just the actual main gear. I can move it up and down slightly. I took everything apart and verified the small shim was in place between the tail drive gear and the middle bearing block. Do I need to add another shim between the main gear and the tail drive gear?

Also, I'm having a weird issue with the belt. If spin the head clockwise like normal the belt slowly moves until it is all the way to the right side of the tail gear. The tension pulley does not stop it. But if I rotate the head backward the belt stays in place. I have disassembled it several times to verify the belt wasn't twisted or anything else but I can't find the problem. For the record the tail grips rotate up (counterclockwise when facing them) when the head spins in the normal clockwise direction.

If the belt is driving backwards it will fall off the pulley .. the tail should be turning counter-clockwise, i.e., blades sweep under and into the rotor wash.

You lost me on the tail drive gear, you mean the forward pulley? If so, you gotta really wrench down and tighten those bolts. Use needle nose pliers on the pulley bolt or it will dig into the side of the assembly.

Let me know if you have questions or PM me and we can get on the phone and go through it.

The play in the tail pulley when the bolt is in place is normal and meant to be there. The belt issue is simply because you have your belt not correctly turned. Sometimes turning the belt around so that the writing is facing left not right or vice versa also fixes the issue.

Flipping the belt around fixed the issue. Thanks.
