Valve Body Assembly: Inspection
- Wash all parts in solvent and air dry only. DO NOT wash in water or use fluffy rags for drying as rust and lint will cause valves to stick in bores. Check all parts for burrs and scores.
- Replace assembly if excessive wear, rust or damage is found. When valves are clean and lubricated with fluid, they should fall of their own weight in respective bore. If not, inspect valves and body for valve or bore damage.NOTE: Several valve body springs have the same dimensions but are not interchangeable due to different tolerances. Ensure all springs are the correct type for the application and are installed in their proper positions.
- Check all springs for damage and collapsed coils. Take care not to disturb settings of adjusting screws; pressures affected by these screws can only be measured and adjusted accurately on a test stand.
- If transmission was disassembled due to failure to shift into 3rd gear, trouble may be caused by a missing sealing ball in transfer plate. If any ball is missing, use following procedure to install replacement balls.
- To install NEW sealing ball, stick .118" (3 mm) diameter ball to end of 8 mm punch with small amount of grease. Drive ball flush into hole of transfer plate. See Fig 1 .
NOTE:
On accumulator piston with separate sealing ring, install ring with lip toward pressure side of piston. Both separate and bonded sealing ring type pistons are interchangeable.
