Illustration 1. Tools for installation of crankshaft seals.2. Put the 6V4002 Forcing Brackets on a flat surface with the studs up. See Illustration 2.3. Place the seal adapter on the forcing brackets as shown in Illustration 2.
Illustration 2. Adapter in position on 6V4002 Forcing Brackets.4. Put the seal and wear sleeve on the adapter with the seal lip up. Do not put sealant or lubricant on the seal or wear sleeve. A sealant is put on the parts before they are shipped.5. Put the 6V4001 Forcing Ring over the studs for the forcing brackets, and over the seal. Install four 5/16"-18 nuts on the studs. See Illustration 3. Tighten the nuts evenly until the forcing ring pushes the seal completely against the bottom of the bore. Remove the forcing ring.
Illustration 3. Use of 6V4001 Forcing Ring to install seal on adapter.6. Install the two 5/16"-18 guide studs in the top holes in the engine housing.7. Use the 2N5006 Bolts to install the 6V4003 Locator on the crankshaft. See Illustration 4.8. Lubricate the O-ring seal on the adapter and slide the adapter into place on the guide studs. See Illustration 4.9. Install the 6V4001 Forcing Ring over the small diameter of the 6V4004 Installer. Make sure the forcing ring fits completely against the shoulder of the installer. With the parts together, slide the forcing ring over the guide studs, until the installer is against the seal adapter. See Illustration 5.10. Install the 9S8858 Nut.
