Preparation For Disassembly
Remove the Torqmotor from the machine, drain it of
fluid, and take it to a clean work surface. Clean and dry
the Torqmotor before you start to disassemble the unit.
As you disassemble the Torqmotor clean all parts,
except seals, in clean petroleum-based solvent, and
blow them dry.
Keep parts separate to avoid nicks and burrs.
Discard all seals and seal rings as they are removed
from the Torqmotor. Replace all seals, seal rings and
any damaged or worn parts with genuine approved ser-
vice parts.
