INSPECTION AND ADJUSTMENT
2-2. Inspection
If measurement results indicate the pressure deviating
from maximum circuit pressure range, make a inspection in
accordance with procedure described below.
①
Remove plug and valve from high pressure check relief
valve port (1-10) or (1-12) of vibrator pump.
*High pressure relief valve (Reverse) : (1-10)
*High pressure relief valve (Forward) : (1-12)
②
Check removed high pressure relief valve for trapped dirt
and other abnormalities.
③
If trapped dirt is present, disassemble and clean high
pressure relief valve.
④
If pressure still deviates from maximum circuit pressure
range after valve is disassembled and cleaned, replace
high pressure relief valve.
⑤
After inspection, measure pressure again and check that
pressure reaches maximum circuit pressure range.
N•m
Plug : 70 N·m (52 lbf·ft)
(NOTICE)
Carefully disassemble and reassemble after taking
steps to prevent foreign material from getting in.
* High pressure relief valve = S.C.R. (System Check Relief) valve for charge check and high pressure relief.
The numbers “1-10” and “1-12” appearing in above illustrations are consistent with lead line numbers shown
in illustration of vibrator pump in “2-2. Hydraulic Component Specifications” (page 4-008).
