Before Servicing

Always use SANYANG genuine parts and
recommended oil. Using improper parts may
cause damage to or destruction of the vehicle.
Special tools are designed for removal and
installation of component parts without
damaging them. Using wrong tools may result
in parts damage.
When servicing this vehicle, use only metric
tools. Metric bolts, nuts, and screws are not
interchangeable with the Britain system, using
wrong tools and fasteners may damage this
vehicle.
Clean the outside of the parts or the cover
before removing it from the vehicle. Otherwise,
dirt and deposit accumulated on the part's
surface may fall into the engine, chassis, or
brake system to cause damage.
Wash and clean parts with high flash point
solvent, and then blow dry with compressed air.
Pay special attention to O-rings or oil seals
because most of the cleaning agents have bad
effect on them.

Never bend or twist control cables to avoid
unsmooth control and premature worn out.
Rubber parts may become deteriorated when
old, and be damaged by solvent and oil easily.
Check these parts before installation to make
sure that they are in good condition, replace if
necessary.
When loosening a component which has
different sized fasteners, operate with a
diagonal pattern and work from inside out.
Loosen the small fasteners first. If the bigger
ones are loosen first, small fasteners may
receive too much stress.

transmission parts in the proper assemble order
and tie them together with a wire for ease of
installation later.
Note the reassemble position of the important
components before disassembling them to
ensure they will be reassembled in correct
dimensions (depth, distance or position).
Components not to be reused should be
replaced when disassembled including gaskets
metal seal rings, O-rings, oil seals, snap rings,
and split pins.
