Testing the flow divider (if fitted)
- Connect a flowmeter to a quick-disconnect coupling
on auxiliary spool valve no.1 located by flow
divider "D"
(Fig.
3).
Connect the return directly to the housing via the
transmission filler port.
- Connect a suitable pressure gauge to the diagnostics
connector (1)
(Fig.
1).
I
: Check that the flowmeter load valve is
MPORTANT
open fully.
- Activate the spool valve.
- Adjust the flowmeter load valve to obtain P1.
- Check the flow rate of the divider by turning the
adjusting knob shown
- Check Q2.

Checking kick-out pressure on an auxiliary
spool valve fitted with automatic return to
neutral
- Connect a flowmeter to the relevant spool valve
(no.3 for example)
(Fig.
- Connect a suitable pressure gauge to the diagnostics
connector (1)
(Fig.
1).
- Run the engine at 2200 rpm.
- Activate the spool valve in automatic return position.
Release the lever and gradually shut the flowmeter
load valve until the lever returns to neutral position.
- Check the kick-out pressure:
P1 = 150 - 170 bar.
I
: Make sure that the spool valve is in the
MPORTANT
automatic return position and not in the floating posi-
tion.
N
: Do not consider the value of the pressure
OTE
gauge fitted to the flowmeter. Look at the separate
pressure gauge connected to connector (1)
