①
Remove plug and valve from high pressure check relief
valve port (13) or (14) of propulsion pump.
*High pressure relief valve (Forward) : (13)
*High pressure relief valve (
Reverse) : (14)
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)
