(5) GST Valve Assembly

NOTE
• The GST valve has been precisely machined and assembled.
It is advisable not to disassemble it. If unavoidably necessary to do it, take the following precautions.
1. Tighten up the screws and nuts to their specified torques.
2. Be sure to clean the disassembled parts and dry them up with compressed air.
3. Do not wear any gloves other than rubber ones not use waste cloth. This is important for keeping the parts clean
and free from rust.
4. Be careful not to drop the parts on the floor or workbench. Check any part, if dropped, for hit mark, scratch and
burr.
5. Be sure to use a rubber or plastic hammer for reassembling.
6. Do not use a wire brush nor polish any part with sandpaper.
7. Apply super UDT oil to the O-rings and oil seals before reassembling. Do not use any metal-cleaning liquid.
GST Valve Assembly
1. Remove the GST valve cover.
2. Disconnect the pressure switch connector (1), proportional
reducing valve connector (2) solenoid connector (4) and oil
temperature sensor connector (5).
3. Disconnect the GST delivery pipe (3).
4. Remove the GST valve assembly (6) with using two jack bolts.
NOTE
• Do not fall down the shift pin while assembling.
(When reassembling)
• Place the 1-2 shift pin (7) and the 3-4 shift pin (8) at neutral
position, main range shift pin (10) at L position (forward) and
sub-range pin (11) at Hi position (rearward), and then assemble
the GST valve.
• Be sure to match the each shift pin and shift piston.
• Install the GST valve assembly (6) by hand, and then tighten the
screws. Do not use the hummer.
• Apply liquid gasket (Three Bond 1208C or equivalent) to joint
face of the GST valve assembly.
