NOTE: Make sure that all seal surfaces and seal cavities are free from nicks and corrosion. If any part is nicked or corroded where sealing occurs,
replace the parts to make sure they seal properly.
NOTE: Wash all parts in a clean petroleum-base solvent. Blow air on the parts until dry.
1. Inspect the housing cylinder bore. Some scoring marks are normal. If there is internal leakage greater than 3.8 liters/min (1.0 gpm), make sure
there are no damaged seals before replacing the housing.
2. Inspect the housing faces for nicks that would prevent proper sealing. Replace the gear housing if these nicks are present and cannot be easily
removed with a fine-tooth flat file without changing the dimensional characteristics, or if depressions are located in a seal area.
3. WARNING: Since solvents are flammable, be extremely careful when using any solvent. Even a small explosion or fire can cause injury
or death.
WARNING: Wear safe eye protection and make sure to comply with OSHA or other maximum air pressure requirements.
Inspect the teeth of the rack piston for cracks and wear.

If a step is detected by running a fingernail horizontally across the tooth surface, the rack piston, the sector shaft and the set of 32 service balls
for TAS4O must be replaced.
