Description
Early engines were build with collar and ring seals but these were later replaced with a sleeve and poly lip seal. The seal part number (this part) is 15053 and is a press fit into the housing but to convert from ring and collar, additional sleeves are also required over the crank: 15023D at the driving end and 105023B at the driving end.
These crank seals are made with a metal case outer and internal poly seal. Stuart part number 15053
