Pilot valve assembling
To reassemble the pilot valve, follow the above disassembly procedure in reverse order.
Pilot valve assembly cautions
– Clean and check all the parts. If any part is defective, replace or repair it.
– Replace all the O-rings and seals with new ones.
– Apply the specified torque to tighten each main part.
– Apply a thin coat of hydraulic oil or grease to each part before reassembly.
– Measure the resistance of each coil magnet assembly.
The resistance should be 62 Ω at normal room temperature [(20ºC) (70ºF)]. If measured in extremely low temperatures the resistance will be less, and at operating temperature the resistance will be higher.
– Be aware that the assembled parts, such as the push rod, spring, etc. are different depending on the ports. Use the correct parts.
– Insert scraper (41) in correct direction.
– Do not push push rod (37) too much with the set screw while adjusting the position of the lever (31). It may cause bumping at Neutral position, resulting in unexpected movement at starting the engine.
