(4) Pressure adjustment of relief valve
Reassembly and adjustment
➀ Remove the oil pressure take-out plug (3/8 NPTF)
from the port C1 (see the right figure).
➁
Install a pressure gauge (0 – 200 kgf/cm
2
) to the port
C1.
➂ Start the engine and keep the engine speed at 2500
rpm.
➃
Set the valve at the S (closed) position and read the
indication on the pressure gauge. (Complete in a short
time.)
Relief set pressure
12.7 – 13.2 MPa
(130 – 135 kgf/cm
2
)
➄ Adjust the set pressure by increase or decrease the
number of shims as shown in the right figure.
The pressure varies about 0.265 MPa (2.7 kgf/cm
2
) by
0.1 mm of shims.
NOTE:
1. A kit contains 3 shims of 0.1 mm and 0.35 mm in
thickness respectively (6 in total).
2. Remove the pressure gauge, wind seal tape on
the plug and install taking care not to allow the
seal tape to enter the hydraulic piping.
➅ Return the valve secrely to “O” position after
