Test Procedure (continued)
6. Use the InfoCenter Display to set reel speed control to the full speed position.
Ensure that the mow/backlap lever on mow control manifold is in the M
OW
position.
Note: Use a graduated measuring container, special tool TOR4077, to
measure case drain leakage ( Figure 97 ).
7. Start engine and run at idle speed. Check for any hydraulic leakage from test
connections and correct before proceeding with test.
CAUTION
Cutting unit reels will rotate when performing the motor efficiency
test. Keep away from cutting units during test to prevent personal
injury from rotating reel blades. Do not stand in front of the machine.
8. Sit on seat and increase engine speed to high idle speed. Engage cutting
units.
9. While watching pressure gauge on tester, slowly close flow control valve on
tester until a pressure of 8,274 kPa (1,200 psi) is obtained.
10. After achieving 8,274 kPa (1,200 psi) , place disconnected motor case drain
hose into a graduated measuring container (e.g., Toro #TOR4077) and
collect hydraulic fluid for 15 seconds. After 15 seconds, remove hose end
from container. Then move the reel engage switch to O
FF
, open the tester
flow control valve and shut off the engine.
11. Identify amount of fluid collected in the graduated measuring container.
Record test results.
For Reelmaster 5410 series machines, if flow was greater than 473 ml (16.0
fl oz) (0.5 gallons/minute/1.9 L/minute) , repair or replace the tested reel
motor; refer to Servicing the Cutting Reel Motor (Casappa) (page 6–205) .
For Reelmaster 5510 and 5610 series machines, if flow was greater than
662 ml (22.4 fl oz) (0.7 gallons/minute/2.6 L/minute) , repair or replace
the tested reel motor; refer to Servicing the Cutting Reel Motor (Casappa)
(page 6–205) .
If flow is less than the listed specifications, the tested motor does not have
excessive leakage.
12. After testing is completed, ensure that the engine is shut off, then relieve
hydraulic system pressure; refer to Releasing Pressure from the Hydraulic
System (page 6–8) . Disconnect tester from motor and return hose. Connect
return hose to the reel motor. Remove plug from machine bulkhead fitting
and connect case drain hose to the fitting.
13. If necessary, perform reel motor efficiency test on other reel motors.
