It sounds to me as though it may have just been worn to a different shape. Personally I prefer the non-rock flat bottom keys which might appear strange to some if seeing them for the first time. Could it have been a step key? | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | I'm familiar with the shape of the key he's describing, it's normal, yet not as common as the regular round ones.
The ones I've used and bought are for the cam and balance pulleys on a Detroit 53 series.
Measure yours and I'll see if I have an old one to measure. If the same I'll dig up a part number and point you in the right direction to buy one.
