The "Bolt-in" sand seal aluminum collar must be glued into place, more appropriately maybe it should be called a "Glue-in"
sand seal kit. Gasgacinch or other similar sealants work well for installing the collar. Additionally, having the collar
swedged by a muffler shop so it fits in the case snuggly can help to ensure a tighter fit.
The "Bolt-in" aluminum collar requires a longer snout on the pulley which spaces it further away from the engine case. The
pulley must be used with longer crankshaft bolt (linked here)
and pulley spacers (linked here
to prevent the sand seal style pulley
from hitting the collar. The collar can not be used with
standard crankshaft pulleys
The seal inside the collar has a 2.26" OD and a 1.725 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.
