I just purchased a 140 H1 (14H). The previous owner stated it was running great up to about a week ago when the spark plug blew out of the head. The threaded sleave was blown out with spark plug if this helps. Is this an easy fix? Can a machine shop be of any help or will I need to find a replacement head? Any help would be greatly appreciated.
Thanks,
Dan

From what he says, I gather it had an insert previously but yes, an automotive machine shop can fix it easily. It may take more than a new helicoil though.

There used heads on ePay all of the time.
Use key words "K321" along with "John Deere 140".
There are 4 under K321.
I can't post a link as that is against the rules but you get the idea.
May be cheaper than having the old repaired anyway.

Dan,

We have had a head previously with a helicoil but it has blown out again. We got to run it to a machine shop soon but instead of another helicoil we are going to get him to make an insert for in there.

Just my 0.02.
