AR1699 | PTO Gear Box Assembly, 1-3/8 in Shaft

Overview

AR AR1699 Gear Box Assembly – PTO, 1-3/8" Shaft
The AR AR1699 gear box assembly is a heavy-duty power transmission unit engineered by Annovi
Reverberi to deliver robust, efficient, and dependable torque transfer for power take-off (PTO)
systems. Designed with a 1-3/8" shaft, this gear box provides smooth, precise mechanical
coupling between tractors or industrial engines and AR high-pressure pumps, ensuring reliable
performance in agricultural, commercial, and industrial environments. Built from premium
materials and engineered for long-term durability, the AR1699 delivers efficient power
conversion, stable speed reduction, and extended service life under demanding working conditions.

Rugged Housing for High-Torque Duty

The AR1699 features a heavy-duty housing constructed from high-strength cast iron or alloy steel,
providing exceptional rigidity and vibration resistance. Its reinforced structure is designed to
withstand heavy torque loads and constant operation, making it ideal for PTO-driven pump systems
that run for long periods under fluctuating conditions. A corrosion-resistant finish offers
long-term protection against weather, moisture, and harsh chemicals so the gear box maintains its
integrity and performance in outdoor and industrial environments.

Hardened Gears & Balanced Speed Reduction

Inside, precision-ground, hardened steel gears are engineered for optimal torque distribution and
power efficiency. The gearing system is designed to handle the high input torque of PTO systems,
reducing rotational speed to match the ideal operating range of AR high-pressure pumps. This
balanced reduction ensures consistent water flow and pressure without over-speeding or mechanical
strain. A deep-tooth gear profile maximizes surface contact for smooth, quiet operation and
exceptional durability, even under high-load, high-frequency use.

1-3/8" PTO Shaft & Pump Interface

The 1-3/8" input shaft is built to standard PTO specifications, ensuring seamless connection
to tractors or industrial engines without additional adapters. Precision machining guarantees a
tight, slip-free fit and smooth engagement with PTO splines, maintaining balanced rotation and
consistent torque transfer. The output shaft is designed for direct compatibility with AR
high-pressure pumps, preserving perfect alignment for efficient mechanical coupling. This
precision engineering reduces vibration, minimizes wear on both shafts, and supports long-term
system reliability.

Sealed Oil Bath Lubrication

The AR1699 uses a fully sealed oil bath lubrication system that provides continuous lubrication
and cooling for internal gears and bearings. The sealed design prevents contamination from dirt,
water, and debris, ensuring clean, smooth operation while extending maintenance intervals.
High-quality oil maintains an even film across all moving parts, reducing friction, noise, and
heat generation. This self-contained system significantly contributes to the gear box’s extended
lifespan and consistent performance over time.

Easy Installation & Stable Mounting

Installation of the AR1699 is straightforward and secure. A pre-drilled bolt pattern and
precision-machined mounting flanges align perfectly with AR pump housings, providing a quick,
accurate fit. The heavy-duty casing and balanced design keep the gear box stable under load,
preventing misalignment or vibration during prolonged use. Once mounted, the assembly maintains
permanent alignment between the PTO and pump, enabling reliable, near maintenance-free operation.

Performance in Demanding Applications

In operation, the AR1699 delivers steady, efficient performance under heavy-duty conditions. The
calibrated gear ratio keeps the pump within its optimal speed range, preventing excess wear and
extending system life. High torque capacity and smooth gear engagement minimize vibration,
reduce mechanical noise, and support consistent pressure and flow. These characteristics make the
AR1699 an excellent choice for large-scale agricultural spraying systems, irrigation pumps, and
industrial cleaning machines where reliability and efficiency are critical.

Quality Assurance & Low Maintenance

Each AR1699 gear box assembly undergoes rigorous quality control and testing under Annovi
Reverberi’s strict manufacturing standards. Every unit is checked for dimensional accuracy,
torque handling, vibration control, and lubrication integrity before shipment. Maintenance is
minimal thanks to the sealed lubrication design and durable construction—routine oil checks and
occasional replacement are typically all that is required. When properly maintained, the AR1699
delivers years of uninterrupted operation and dependable performance across a wide range of
heavy-duty applications.
