Crankshaft oil seal

Hi all I was looking to sort my landys ( 2.25 petrol ) oil leaks out and the worst one seams to be from the front bottom pulley crankshaft, is it a simple job? By that I mean pulley off seal out new one in or more complexed? Many thanks jonny

I will be doing this too shortly.

there are 2 ways of doing it .if front shield is screwed to timing cover you can remove and change seal if its riveted then you need to remove timing cover and change seal ,shield rivets can be drilled out to help if you want and replaced with screws,its easier with shield removed but not necessary
