I was having transmission issues, but figured I’d replace the drive shaft and block while I had the machine torn up anyway. Now I can’t get the drive block on. When i installed the basket drive it was a tight fit (couple smacks with a hammer to get it in tight) figured that was a good thing until I went to re-install the new drive block. Im getting metal shavings trying to tap it on! Part #s say they’re replacement parts for 388952 & 389140. Any advice? This can’t be normal...
