147 differences in idler pulleys
Hello,
There are two different part numbers for the idler pulleys, 493164-R91 and 61176-C92. I know the latter is for the later serial numbers, but I think the serial tag is gone, plus its location is covered by the PTO. Is there a physical difference between the two pulleys or can I just get the later pulley and be good? Thanks in advance.
