Rear Main Seal Installer for Navistar/International DT466/DT466E
There seems to be quite a bit of confusion with which rear main seal installer tools are needed for the Navistar/International DT466/DT466E and the 530/570 series of engines. The keys to getting the correct rear main seal tools is to measure the diameter of the crankshaft and by knowing the actual seal number. Here is a breakdown of the seal numbers, crankshaft diameter size and the proper tool for each:
  • ZTSE2535C or ST-154 for seal 1809964C92 / 5" crank
  • ZTSE4749 or ST-141 for seal 1817867C93, 1817867C92, 1817867C91, 1817767C1, 1817865C1 / 5-1/2" crank
  • ZTSE4637 or ST-153 for seal 1841938C1 / 6-1/8" crank

We have learned that many service manuals give the incorrect tool number for the DT466/DT466E engines since they do not take into account the crankshaft size.
