Question:
I have a 5521 chv Product # is 96143000100, serial # is 121404000385. On part # 532 18 45-90 (key # 46 in the Ilistrated part list) is there a woodruff key with it,(not the key that is cast into the blade adapter)I took my blade off to sharpen it and when i put it back together the next day I notice a spot for it on the shaft. So if there is then I aperently lost it. Is it a common size i can get at my local hardware store?
Part number 532 18 45-90 has a key molded into the adapter. There is not a separate key. If there is not a key molded into part, you will need to replace 532 18 45-90.
