Reassembly precautions
1. Whenever the O-rings, oil seals, and snap rings are removed, they must be replaced with new ones.
2. Thoroughly wash the parts and allow to dry. They must be kept free from cleaning oil and dust.
3. Reassembly procedure must be performed in clean place. Ensure that the parts are kept away from the waste threads or other dust particles.
4. Cleaning oil tends to stay inside the front casing. Remove it completely by blowing compressed air.
5. Ensure that the parts are free from rust. (Use specified hydraulic oil for rust prevention after cleaning and drying.)
6. Reverse the sequence of disassembly procedures.
Apply the grease to the oil seal and inner surface of front casing (at bearing location).
CAUTION: Make sure that the front body internal surfaces are free from damage.
Attach ST to the front body. Using a press, install the oil seal.

Install the spring into the front casing. Then, with spool valve dipped in specified hydraulic oil, install it into the front casing.
Using a 5-mm dia. round bar, ensure that the valve moves smoothly.
Set the O-ring, with grease applied to it, onto the connector and secure connector to the front casing.
CAUTION:
- Use care to prevent damage to O-ring at installation.
- When tightening the connector, ensure that the O-ring does not protrude or get caught.

Fix the oil pump pulley temporarily.
When the reassembly procedures have been completed, turn the shaft by hand to ensure it turns smoothly. If it binds or other unusual conditions are evident, disassemble again and check for foreign matter trapped on sliding surfaces and improper installation. Eliminate the cause of trouble.
