Use 2 people to perform all the tests, with 1 person in the seat and
the other to read and record the test results.
1. Clean the machine fully before you disconnect or disassemble the hydraulic
components.
Note: Cleanliness is required whenever you work on the hydraulic
equipment. Contamination causes too much wear on hydraulic components.
2. When you perform tests on the hydraulic system, wear eye protection.
3. Before you perform a test, check the traction control lever linkages for
improper adjustment, binding, or broken parts.
4. Perform all the hydraulic tests with the hydraulic fluid at normal operating
temperature.
5. Install clean metal caps or plugs on the hydraulic lines that are left open or
exposed during the testing or component removal.
6. When you use a hydraulic tester (pressure and flow), ensure that the inlet and
outlet hoses are properly connected and not reversed to prevent damaging
the hydraulic tester or components. Fully open the tester load valve before
you start the engine to reduce the possibility of damaging the components.
7. Install the hydraulic fittings by hand and ensure that they are not
cross-threaded before you tighten them with a wrench.
8. Position the tester hoses to prevent the rotating machine parts from
contacting and damaging the hoses or tester.
9. After you connect the test equipment, check the hydraulic-fluid level in the
hydraulic tank and ensure that the tank has the correct fluid level.
10. When you use a hydraulic tester (pressure and flow), open the tester load
valve fully before you start the engine to reduce the possibility of damaging
the components.
11. Ensure that the engine is in good operating condition before performing any
hydraulic test.
Note: Use the InfoCenter to check the engine speed when you perform
a hydraulic test. The engine speed can affect the accuracy of the tester
readings.
12. If there is a traction circuit problem, perform 1 or more of the following tests:
traction circuit relief valve (R3) and (R4) pressure, traction circuit charge
pressure, gear pump (P3) flow, front wheel motor efficiency and/or piston
(traction) pump flow tests.
13. If there is a lift circuit problem, perform 1 or more of the following tests: lift
relief valve (SVRV) pressure, gear pump (P4) flow and/or lift cylinder internal
leakage tests.
14. If there is a cutting (mow) circuit problem, perform 1 or more of the following
tests: relief valve (R1) or (RV1) and (R2) or (RV2) pressure, gear pump
(P1) and (P2) flow and/or cutting reel motor efficiency tests. The cutting reel
motors used on the Reelmaster 5510/5510-D/5610/5610-D include a cross
over relief valve that can also be tested.
15. If there is a steering circuit problem, perform 1 or more of the following tests:
steering relief valve (R10) pressure, steering cylinder internal leakage and/or
gear pump (P3) flow tests.
