I have to admit that I c0cked badly when fitting the crank seal. I used some tape around the crank nose to slide the seal on. The inner lip did not slide on properly and the edge was visible. So, I eased the lip in with a very thin piece of smooth, blunt, plastic. It did not work and there is an oil leak! I have had to order a new seal. Found one at a good price on ebay. I asked the dealers for the price of a pukka T10053 installation tool. There were 2 trainees only working at the dealers, the manager and the experienced guy were both on annual hols. They could not even find the tool! So I had to make my own. I was lucky to find a top of a shoe cream bottle exactly the right size to the protection sleeve! I was also lucky to have a piece of tube the right inside diameter for the pusher! These new seals are, IMHO, a crap design when compared with spring-lip seals! A flippy-floppy flimsy bit of PTFE is not the best way to seal a rotating shaft! I believe they were introduced some time after 1997. The APY Head that Carey sent me had NBR spring-lip seals. I tried to find VITON spring-lip seals but 35 x 48 x 10 is not an industry standard. There are aftermarket NBR seals for Japanese motor cycle forks, but these are a linear seal not rotating! The original NBR spring-lip seals used by VAG are NLA! NOW! Back in the 1970s VAG used VITON spring-lip seals. This is one from a Mk1 Golf Camshaft - 026 103 085 Replaced at some time before 1983 by an NBR seal - 026 103 085D Downhill to cheap and nasty all the way folks!
