Blow Pressure Inspection - Honda BF135A Manual

3) Lower the outboard motor slowly to the lowermost
position by loosening the manual valve.
4) Tighten the manual valve securely.
5) Hold the outboard motor in the lowermost position for five
minutes.
6) Then, push the "UP" side of the power tilt switch and raise
the outboard motor to the uppermost position. Hold the
outboard motor in this position for five minutes. After five
minutes, check the fluid level in the oil tank (P. 15-47).
7) Repeat the procedure from step 3 through 6 five times.

6. BLOW PRESSURE INSPECTION

After bleeding air from the power trim/tilt assembly without
mounting on the outboard motor and checking each rod for
proper compression, perform the following operation in the
same manner as bleeding air without mounting on the
outboard motor.
1) Operate each rod of the power trim/tilt assembly (i.e. move
them up and down) several times and set the rods in the
full extended position.
2) Check that the Automatic Transmission Fluid (ATF) is at the
upper level in the oil tank (P. 15-47).
3) Using the special tools, check the blow pressure at the
upper and lower chambers of the cylinder.
a. LOWER CHAMBER BLOW PRESSURE
1) Remove the internal circlip and manual valve from the
power trim/tilt assembly.
• Note that Automatic Transmission Fluid (ATF) will spurt
out when the manual valve is removed without the rods
fully extended. Move each rod to the fully extended
position before removing the manual valve.
• A small amount of the Automatic Transmission Fluid
(ATF) will flow out when the manual valve is removed.
Attach the special tools quickly.
2) Attach the special tool (oil pressure gauge joint B) for
measurement of lower chamber blow pressure to the
manual valve installation section as shown.
Tighten the special tool to the specified torque.
TOOL:
Oil pressure gauge joint B
TORQUE: 9 N . m (0.9 kgf . m, 6.5 lbf . ft)
3) Attach a commercially available pressure gauge [P/T 1/4]
which measures 14,710 kPa (150 kgf/cm
above to the special tool (oil pressure gauge joint B).
