TESTING AND ADJUSTING
Pressure to be tested
Pressure tap
Pressure requirement
Main relief pressure
M (G 1/8", with 0-ring)
With engine running at high idle speed and
control lever kept in neutral, this pressure is
required to take the following value:
21 kgfJcm2 (299 psi) [2 MPa]
If not, replace main relief valve spring.
1st-speed, 2nd-speed
S (G 1/8", with 0-ring)
With engine running at high idle speed, this
and 3rd-speed clutch
pressure is required to remain at a level equal
pressure
to main relief pressure.
Forward and reverse
D (G 1/8", with 0-ring)
With engine running at high idle speed, this
clutch pressure
pressure is required to take the following value:
0 kgf/cm2 for both clutches with control lever in
..
neutral.
.
Not lower than main relief pressure by 2 kgf/cm2
(28 psi) [0.2 MPa], with control lever in 1st, 2nd
.
or 3rd speed position.
Shifting time
S (G 1/8", with 0-ring)
Measure time required for pressure to change
when control lever is shifted from neutral to any
position, or from one position to another.
