Agitator For A 1975 LKM Washer
Hi JR, As I mentioned before you can use almost any WP-KM Belt Drive washer agitator in your Moms machine, the best replacement is the WP Double-Duty Surglator, But really any agitator will work that is not Bakelite.
If the splined area of the agitator where the agitator attaches to the agitator shaft is very rusted a new agitator may not last long, you may have to replace the transmission or at least the agitator shaft for a lasting repair, and on a washer of this age a complete rebuild is likley in order.
