550 Crankshaft Pulley 4-276 engine

Post by LewM » Tue Jan 15, 2019 3:10 pm

My crankshaft pulley is lined with stainless steel where it goes through the timing cover and seal. It has grooves in it that look like its made that way. Is it suppose to be that way or are they worn in it? If so what can be done about the grooves?
Thanks,
Lew
