If the lower tool bushing has been removed from the front head, you must perform the following steps before you install the lower tool bushing.Note: Do not apply 5N-5561 Silicone Lubricant to the bore of the front head.
Refer to Illustration 3. If you have previous lower tool (4), remove O-ring seal (6) from groove (7). Do not replace the O-ring seal. Silicone sealant will replace O-ring seal (6). Go to Step 5.b.
Apply a thin layer of 5N-5561 Silicone Lubricant (11) on the outer surface of lower tool bushing (9). Refer to Illustration 4 for applying the silicone sealant.
Apply grease (10) to the bore of front head (8). Grease will prevent corrosion and seizures. The removal of the lower tool bushing will be made easier by applying grease. Refer to Illustration 4.
Install the lower tool bushing before the sealant hardens. Install the retaining pins.
