If it's an inherent design flaw which it sounds like it is then yes they should repair all of them.
The 220 series ultra shor throw ones we've got haven't suffered this issue but then so far touch wood neither have our others.
We have had three so far out of the eleven here fail with similar issues - Hitachi don't seem to want to know and the reseller is no longer trading. I have bought two replacement motors from the only UK supplier listed on Hitachi's website but at £75 each plus the time it takes to fit its not proving very fruitful in the long run!
@plexer - I have a complete motor unit with a damaged cog if that is of any use? :)
They arranged warranty repair on one of ours (warranty expired) in next to no time. Guy came in yesterday and replaced it. If you track back through the posts on this subject, there's a contact name at Hitachi.Quote:

@BaccyNet would be helpful in testing the stl file to 3d print that I've now received from slayer
I've recently bought an ED-A111 with the same problem. I've opened it up and found the exact same thing - the cog is cracked. I've emailed Hitachi with the slim hope that they'll be able to provide a replacement. Ben - I'd be happy to send you the broken cog but at the moment I can't work out how to get the thing off!
Which cog has broken I have some 3d printed ones of the 35 tooth one I think it is. If not if you can get it off that'd be cool.
It's this little 5 tooth one. I've stuck a red arrow pointing at the location of the crack. Just about visible on the pic!
Ok cool if you can work out how to get it off I'll see what I can do.
Great - thanks! I'm still trying to figure it out without breaking the thing...
i got a .stl file for that one also, send me a pm and I will mail it to you :)
@Skyper you've got my email from the 35 tooth one still? send it to that please.
You got mail!
Got it thanks.
