In this video I show you how i changed the crankshaft seals in my 1970 Kawasaki H1 500 triple. I used my Sykes Picavant bearing extractor, Permatex Ultra grey gasket sealer. The inner crankshaft seals came from CruzinImage in Japan, New engine seals and gaskets came from Z Power Kawasaki UK and friction reducing oil from ZX1 Extralube. The job was delayed half a day when i hit my thumb while truing the crankshaft with my 2kg copper hammer! but i was seen by the excellent staff at my local A&E. Thanks to my son Stephen who helped with the tracking shots at the end of the video, check out his Instagram at stephen_millyard.
