Yes mate,if it needs it! I've been back to see the mechanic that has just fit the new seal ,he told me the crankshaft must be worn as he's done hundreds of these seals,it was lubed up with grease before he fit it apparently! Its a Teflon seal so should go on dry! Anyway I've got access to a workshop and 4 post lift at work so I'm going to replace it myself,would be handy to have a speedi sleeve just in case
