1. Disassembly and Assembly of General Parts
1.1 Oil SealsWhen driving oil seals into place, respect the following instructions. Driving Seals into Housing:(a) Orient the seal lip correctly, making sure it is not damaged.(b) Before driving a seal into place, apply a light coat of grease to the periphery of the seal that fits into the housing.(c) Use a driving tool like the one shown in the drawing that is specially designed for the purpose. The tool can properly guide the lip and hold evenly the top of the seal when it is tapped, so it allows the seal to be driven straight down. Do not use hammers on bare seals as seal will be damaged and consequently oil leak will result.
