Deutz Tractor Tandem Hydraulic Gear Pump Replacement 19cc 13cc

GBC-DEUTZ-19CC-13CC — Deutz Tractor Tandem Hydraulic Gear Pump Replacement 19cc 13cc

The 19cc/13cc tandem configuration in the Deutz tractor range represents a higher output variant compared to the 18cc/12cc pump, reflecting the heavier implement hydraulic demands of larger Deutz models. On these tractors, the primary 19cc gear set delivers sufficient flow for large 3-point hitch implements, front-end loaders, and multiple simultaneous remote cylinder operations, while the secondary 13cc set maintains dedicated power steering supply at all implement demand levels. The additional displacement in both circuits compared to the 18/12 variant makes this pump suitable for tractors operating with heavier, higher-flow implements in demanding agricultural conditions.

The GBC-DEUTZ-19CC-13CC is a complete replacement tandem gear pump assembly with 19cc primary and 13cc secondary displacement. It is essential to confirm that your tractor’s original pump is the 19/13 configuration and not the 18/12 variant — both fit Deutz tractors but with different model applications and circuit pressure requirements.

Technical Specifications

Heavy-Implement Dual-Circuit Applications in Australian Farming

Larger Deutz tractors — those in the 100–150 hp range common to mid-size broadacre operations — use heavier implements that place sustained, high-flow demands on the primary hydraulic circuit. Front-end loaders in particular require fast, high-flow response for quick bucket movements during stock feeding, manure handling, and silage work. The 19cc primary circuit in this tandem pump provides higher flow per revolution than the 18cc variant, translating to faster cylinder speed and more responsive loader performance. Simultaneously, the 13cc secondary circuit maintains consistent power steering with no perceptible drop in steering assistance during loader operations.

When diagnosing tandem pump failure on these larger Deutz models, it is worth noting that seal failure in the shared pump body can sometimes result in cross-contamination between the primary and secondary circuits, manifesting as simultaneous loss of both implement hydraulic pressure and power steering response. If both circuits fail together, the tandem pump assembly is the most likely single cause. Replacing the full {sku} assembly addresses both circuits in a single operation.

Tandem Pump Installation and Circuit Verification

Installation of the GBC-DEUTZ-19CC-13CC tandem pump follows the same procedure as the 18/12 variant but with careful attention to port labelling for the larger displacement circuits. On installation, confirm that the primary 19cc circuit is connected to the implement hydraulic supply line — not the steering circuit — and that the 13cc secondary outlet connects to the power steering inlet. Cross-connection will result in over-pressurised steering and under-powered implement hydraulics, which will quickly damage both circuits. Pre-fill both circuits through their inlet ports before engine start.

After commissioning, cycle the loader (or primary hydraulic implement) and the steering simultaneously to verify that both circuits perform as expected. A pressure gauge check on both circuits confirms that output matches the Deutz service specification for your model. For technical support or to order, visit our contact page.
