I posted here last week about my crank pulley stripping over the splines on the crank shaft on this 1850 Perkins. Found the splines on the crank are still ok. I got a new pulley today from Maibach's via AGCO and its totally different and can't be used. They swear its the proper part but said it's design was updated. The origial has a collar of about 2" that slips over the crank splines, one pulley only and 9 bolt holes to bolt the harmonic balancer to in front of it. The one they sent me has a collar about 3/4", three pulleys on it with a rubber dampner which my original does'nt have and no possible way the harmonic balancer weight will bolt up to it. The collar is so short the spines dont even my any contact. The splines seem to be the only thing common with both pulleys. Whats going on here? Talked to the parts woman and the machanic there an they say they have sold these before with no issues reported. Engine serial # is 8512917 C making it a 3rd and last series perkins for the 1850 by my records. Tractor serial # is 174-804-427 making it a 66 model. Please help with any Knowledge or advice.
