I have a old Echo tiller with a worm-drive transmission that recently
wore out. After a couple hours in the shop and a couple more on
Google I still can't figure out how to take apart the transmission.

Over the last year I've developed a strong emotional attachment to the
tiller after saving it from the dump and nursing it back to health
However I can't bring myself to pay the shop $200 for a brand new
transmission. Upon inspection of the transmission it appears all I
have to do is replace the old worm gear with a new one and put the
washers and bearings back where I found them.

I can't for the life of me figure out how to disassemble the
transmission. The tine shaft seems to be held into place by a
bearing and on either side, but I can't pound or coerce the tine shaft
from the assembly (which seems to be the first step).

Thanks,
Chip

Looking at the picture. The tine appears to insert from one side, so
take it out that side.

Have you tried to twist the tine out?
