How do I remove the torque tube from Lama tail ?
Hi, I am trying to replace the torque tube but the old one on Lama won't budge. Any ideas? Thanks

In most of the cases, you need to remove the entire tail box. Then, you can pull the torque tube out.

Hirobo lama...

If you remove the tail box, the torque tube is already connected so... Pull gentle by turning the tail shaft.

Check this...

Tail box is already out. The front is also disasembled. I wonder what kind of glue was used for the torque tube and the bearings. Tried little force but nothing is happening

Have you tried heat on the bearings to loosen the adhesive used to fix bearing to TTube

Well, you have no other choice...
Probably, the builder used CA as a glue contender. Very bad!
This configuration doesn't need such a glue. The torque tube "float" between both ends.

With a torch, heat the bearings and pull gently the torque tube

Looks like a Robbe Alouette II which typically used the Futura SE mechanics. The bearings may be Loctited to the torque tube, but can you push the bearing support out of the tailboom tube sections?

Yes it has the Robbie future mechanics. I am going to try the heat gun method. Thank you all for the help.
