Perform this test to check PTO clutch hydraulic pressure. This determines if there is sufficient oil pressure to engage PTO clutch.
[1] – Park machine safely.
[2] – Raise and safely support rear axle.
[3] – Lock park brake.
[4] – Remove left rear wheel.
[5] – Remove plug from pressure test port (A).
[6] – Install pressure gauge as follows:
Assemble JTO3366 elbow connector, JTO3017 hose, and JTO3344 pressure gauge in test port.
[7] – Start engine and set throttle at low idle.
[8] – Check and record PTO clutch pressure.
[9] – Stop engine and cycle valves to relieve any pressure.
[10] – Install new O-ring on plug.
[11] – Remove gauge assembly from port. Install plug.
Results
– Pressure should be to specification.
– If pressure is below specification, check PTO clutch seals and PTO clutch pack condition.
