I can't help with the gearbox. But can you please edit your post and change the size of the pictures to prevent users having to scroll side to side to read?
It's simple to do. On your original post click on Edit in the top right corner.
Scroll to the bottom of the edit window and add the words height=480 to the end of the picture links.
Make sure you put a space after the numbers and before the "h" in height. No space between the 480 and the brackets. see example below.
After editing click on the magnifying glass to verify the edit worked.
Thanks
Then click on post to save your changes
