Installation Recommendation
For best results, inspect your variable speed belt during installation. If the existing belt shows signs of wear from a damaged disc, replacing the belt at the same time can help maximize the life of the new disc assembly.
Please verify that your machine has an American-made 2 HP variable speed head and compare the OEM part number before ordering.
