Replaced with Timken seal on Toyota and didn’t expect to see metal covering on it. Visually looked the same dimensions compared to original seal. Covered it light grease and would not go in easily even with large socket around seal, would just go crooked. Eventually got it in straight but ended up lightly denting while tapping in.
I damaged a USED crank seal just like it. Turns out the replacement I had ordered didn’t fit, so I had to put the damaged used one back on.
Never leaked in the 30k miles I had it, doubt it leaks now
