Measure your crank pin. Should measure 1.000" when new.If I remember right, I think the book says .0025" clearance. Not sure why they need that much clearence (probably liability issues even back then) as modern rods only run .001" clearance. I checked a NOS late model Harley rod assembly. The end of the rod had about 3/16" or more shake at the small end !!! I bought a Pro-X rod assembly for my racing Hummer. It had zero shake at the end nor could ya twist it on the crank pin. Harley never made oversize rollers for the late model caged bearings. The slots in the cages would have to be opened up .001 for the +.001 rollers to fit. As Brent says, finding a NOS set of the bearings and cage is next to impossible, (but I am sure if you look long enough, someone may have one). Mutt ----- ORIGINAL MESSAGE FOLLOWS ----- Thank you for the quick reply. My machine is a 63 Scat and the pins measure .121" It has been apart before, someone really tore the plates up. The rod and crank pin look good, I think .122" pins would tighten it up. Does anyone sell these oversize rollers. Thanks again, Scott ----- ORIGINAL MESSAGE FOLLOWS ----- depends on what year/ 48-60 models use .250" x .490 long 61 to 66 use .120" diameter needles ----- ORIGINAL MESSAGE FOLLOWS ----- Can someone please tell me what the stock dimension is for the crank pin roller bearings? Thanks, Scott |
