The sand seal has a 2.26" OD and a 1.665 ID. Sand Seals are intended to keep debris out of the engine at the crankshaft. They are NOT an oil seal for the crankshaft. If you have oil leaking from the crankshaft, the crankcase pressure is too high. The issue could be improper crankcase venting or an indicator of an internal issue such as worn piston rings, too much oil pressure, etc.
The outer diameter of this pulley is roughly 6 3/4"/171mm. Coupled with a standard upper pulley with an outer diameter of 4.25"/108mm the pulley ratio would be approximately 1 to 1.58, meaning the fan will turn 1.58 times every time the cranks makes one full revolution which is less than the factory ratio of 1.69.
