Re: [Amel Yacht Owners] bow thruster maintenance....

Agree with Andrew,

Make sure you removed all the bolts.
I am sure you saw the illustration of the process: http://nikimat.com/bow_thruster_overhaul.html

Don't cut the tube.
Be patient and keep adding penetrating oil and gently use soft hammer to try to loose the components.

Then when you put it back together, make sure to put lots and lots of grease...

If I am
understanding you correctly you are trying to withdraw the
carbon fibre tube of the bow thruster from the cast iron
casing of the bow thruster motor. Assuming you have removed
the two bolts that hold the tube in, then the
tube should withdraw from below, however if this has not
been done for a long time then a lot of patience and
penetrating oil will be required as the inside of the cast
iron casing will likely be rusted. There are quite a lot of
posts written about this problem
and how to approach it, on this forum. However, cutting the
tube is a very bad idea and very expensive and it may not be
possible to get a replacement unit. Patience and
perseverance is the key.

Hello everybody
As anybody ever have a problem with the SM 2000 bow
thruster.
the elect. motor seems to be bonded to the
"carbon"shaft.
Amel sent us a tool,but still is not moving.Pushed
and pulled with  everything i got,still not
moving.
I am now to the point of cutting the tube,which i
can sleeve from the inside  and hope that it's not the
shaft.
does anybody have any kind of experience with
particular situation?
thanks all
Fred
