Helllo everyone ,
itís fair to say Iíve screwed up a few days ago
For some time Iíve been hearing some grinding noise
coming from the drive unit , it was clear it originated from the sliding mechanisme that commands the steering
quadrant to rotate.
So lubricating it was the message , apparently Raymarine
has provided a small service
hole at the base of the main pipe for that ( or maybe that hole is just there to release the air when the piston goes in again ) , which I obviously missed , and had to find out later when my mistake was made .
Underneath I have several pictures explaining everything .
After unscrewing the top main nut and pulling the drive-rod off the worm the lot came out with a big supprise .
I managed to accidentally pull the clip off the end of the worm so the worm- holder came out and so did the bearing balls .
This is where I feld that I was in trouble .
There is no way to get the worm-holder on the worm again and at the same time also get the bearing balls in .
I figured out that the pipe in which the piston slides into has to come off first , assemble all parts
again and finally get that main pipe on again.
This is where Iím stuck.
First of all I canít t the tha back of the autopilot
off even when all 4 screws are out . Is there a fix that I am missing ?
Secondly , how is that main pipe attached to the gearbox
of the pilot ? Is it screwed on or do I absolutely need to get that back off and release the main pipe from the inside .
I will write some reference under each picture so there is a link to the terminology Iíve used in this text.
This a layout that Iíve found on the net showing all the parts
No explanation though on how to get the back ( lefthand side ) or the main pipe off .
The piston pipe on top of the main pipe , if I can get that last one off I Ďm confident that I can get all the bits and pieces lined up again .
The main pipe with worm inside .
As you can see there is no room to get the piston / worm-holder in , make sure the bearing balls stay in place and at the same time get the end lock clip on .
At the end of the piston pipe thereís a loop ( on both sides ) that allow the bearing balls to run through when being pushed by the worm in or out .
Not sure if you can see it properly but next to both loops being filled with balls , also the spiral inside has to be loaded with balls .
I have put some grease on inside to prevent the ball from falling down and tried to get the piston/ worm-holder back on to no avail .
The grease makes it all too sticky and the balls pile up inside when the worm is pushed in .
So agin a pic of the main pipe , is it screwed on by itself to the gearbox
or is their another fix on the back side ?
If this cover comes off I have a view on the inside , all 4 bolts are out what Iím I doing wrong ?
Thanks for your help
