Title: 1Y conrod bearing set number
Post by: thebilgerat on April 07, 2019, 11:02:45 pm

Does anyone have a good number for a conrod bearing set for the 1Y?  The parts supplier sent me bearings for an AAZ which do not appear to be the same at all.

Thanks!

So after some searching it seems that the 1.6L diesel conrod bearings are the ones I want.  Are the conrod bearing ends the same diameter as the 1Y?  Or do I need to buy oversize/undersize?  Rods are standard.

The big-end journal diameter for the 1.6 and the AAZ is the same.  I don't know about the 1Y.  If it is different from the AAZ then it is different from the 1.6.

The problem with the AAZ bearings are the notch.  The 1Y has a small style notch while the AAZ notch is large and goes completely to the edge.  The 1Y rod bearing notch does not go to the edge.

The wrist pin bearings I don't need (small end)
