Is it common for these units to break the second hand wheels pinion?
Ive got two of them here with that problem.
If you have a 974 you want to get rid of, drop me an e mail. plwsnafu@gmail.com

In my experience not at all common Patrick, probaby caused by incorrect or rough handling which is very common.
