4. Remove and install the top spindle bushing first. Install the driver handle through the bottom bore. Position a new bushing on the "T" side stamping of the bushing Remover/Installer Driver. The bushing must be installed on the tool so the open end grooves will face outward when installed. Position the new bushing and driver over the old bushing, insert the handle into the driver and drive the old bushing out while the new bushing is driven in. Drive until the tool is seated. The bushing will then be seated at the proper depth (2.03 mm [0.080 inch)] minimum from bottom of upper spindle boss).

The bushing must be installed on the tool so the open-end grooves will face outward when installed. Position the new bushing and driver over the old bushing in the bottom spindle bore. Insert the handle into the driver and drive the old bushing out while the new bushing is driven in. Drive until the tool is seated. The bottom bushing will then be seated at the proper depth (3.30 mm [0.130 inch] minimum from the top of the lower spindle boss).

6. Ream the new bushings to 0.025-0.076 mm (0.001-0.003 inch) larger than the diameter of a new spindle pin. Ream the top bushing first with the reamer tool. Install the smaller diameter of the tool through the top bore and into the bottom bore until the reaming threads are in position in the top bushing. Turn the tool until the threads exit the top bushing. Ream the bottom bushing. The larger diameter portion of the tool will act as a pilot in the top bushing to properly ream the bottom bushing.
7. Clean all the metal shavings from the bronze bushings after reaming. Coat the bushings and spindle pin with Long Life Lubricant, C1AZ-19590-BA (ESA-M1C75-B) or equivalent.
8. Install a new seal on Bushing Remover/Installer Driver tool on the side with the "T" stamping. Install the handle into the driver and push the seal into position in the bottom of the top bushing bore.
