Reconditioning Track Shoe Grousers by Manual Arc Welding
When the wear of the track shoe grousers reaches a point called the "permissible wear limit"
it should then be decided whether a set of new shoes is to be installed, or whether the old ones are
in good enough condition to be rebuilt by welding a millrolled, specially shaped grouser bar to the
worn grousers.
