This is a Rear crankshaft seal with wear sleeve for IH engines models 312, 360, 361, 407, 414, 436 and 466.
Part #: 1809964C92
This will fit early Navistar engines with 5" crankshafts. This will not fit later Navistar engines with 5 1/2" crankshafts. The picture shows the sleeve separate from the seal for a better visual picture but the seal comes with the wear sleeve installed. They should not be separated. They should be installed together at the same time. Check out my store for the Installation Tool. The Noeprene style is also available.
