AMC sprocket

Post  piston 197 on Thu Oct 19, 2017 6:11 am

The AMC gearbox sprocket will be the same fit on both 17T and 20T, (the 15T one is same fit, but narrower chain, the 25T one is a different spline size )
See Ebay item No 401404220337 AMC 20T sprocket 18 Tooth, this will fit your AMC 17T engine, and think they have the same number of teeth on both 17T and 20T ?
The 15T ones being sold by the same seller ( me !) will also fit, but they are a narrower ( 1/4") chain

Rivet counting again, but here are the part numbers for the various engines, which all differ:

79 (17T) - 041659

80/84 (25T) - 041268

87 (20T) - 041528

Much as I said, 17T and 20T are interchangeable, but may be different Nos. of teeth and may account for the difference in part No? ( 20t has 18 Teeth and 5/16" chain width)
25T is a different , bigger spline fit and is 5/16" chain width
15T same spline fit as 17T and 20T, but has 16 Teeth and 1/4" chain width
