HYDRAULIC SYSTEM

PUMP & MOTOR

The pump and motor is the heart of the hydraulic circuit and is vital to the performance of all Triumph mowers. Worn pumps and motors should be replaced or repaired. It is recommended that most customers replace when this occurs however, spare parts and seal repair kits are available for field repair if desired. ALWAYS DRAIN, CLEAN AND REFILL THE TANK WITH CLEAN OIL when pump repairs are made.

NOTICE: To avoid possible damage to a new or rebuilt pump, run the tractor engine at very low RPM for about 5 minutes with all control levers in neutral position prior to placing in service.

VALVES

The major cause of valve malfunction is dirty oil or foreign material causing the valve spools to be scored or seals to fail. If repairs are required remove the valve from the system and thoroughly clean all parts before reassembly. Replacement parts and service kits are available. The valve body and spools are match fitted and are not interchangeable or adjustable. Check the valve lever linkage for free movement to allow the detents to locate without binding.
