Locate the drain plug on the existing gearbox and position a catch container underneath. Remove the drain plug and allow all oil to drain completely — inspect the oil for metal particles or discolouration that may indicate internal wear. Record the old gearbox model number, mounting bolt size, and shaft dimensions for reference.

Remove the fill plug and slowly add the recommended gear oil until it reaches the level indicator. Use the lubricant grade specified in the gearbox documentation (typically SAE 80W-90 GL-5 or equivalent). Replace the fill plug and hand-tighten, then snug with a wrench. Verify the breather cap is clean and unobstructed.

Park the tractor on firm, level ground. Engage the parking brake and place wheel chocks. Turn off the engine and remove the key. Disconnect the PTO shaft from the self-cleaning filter system. Allow all components to cool completely before touching. Wear appropriate PPE including gloves and safety glasses.

Align the PTO driveline with the gearbox input shaft and slide the yoke onto the splines until the locking mechanism engages. Verify the spline count matches (6-spline for 540 RPM, 21-spline for 1000 RPM). Check that driveline operating angles do not exceed 15° — excessive angles cause premature U-joint failure and vibration.

Clean the mounting flange on the self-cleaning filter system frame with a wire brush and solvent, removing all old sealant, rust, and debris. Inspect the mounting surface for cracks, stripped threads, or warping. Chase any damaged bolt threads with a tap. Apply a thin film of anti-seize compound to the mounting face if specified.

Attach the gearbox output shaft to the self-cleaning filter system’s backwash drive drive coupling. For keyed connections, align the keyway and slide the coupling on, then secure with the retaining bolt and torque to specification. For splined outputs, apply anti-seize to the splines and verify full engagement before locking.

After the first 10 hours of field operation, re-torque all mounting bolts to specification. Check the oil level and top up if necessary. Inspect all seals for any signs of weeping. Verify the driveline guard is properly reinstalled. Record the installation date and hour-meter reading for future maintenance scheduling.

Probable Cause: Қозғалтқыш жолындағы тозған әмбебап қосылыстар

Recommended Action: First check all mounting bolt torques — vibration frequently loosens fasteners, which then amplifies the vibration. Next, inspect the PTO driveline U-joints for wear or binding. Verify driveline angles are within specification. Finally, check the output coupling to the backwash drive for wear or damage.

Probable Cause: Бос ішкі компоненттер немесе бекіткіш жабдығы

Recommended Action: A clunking sound specifically on PTO engagement (but not during operation) usually indicates driveline lash — check driveline telescoping tube for wear. If the clunk occurs during operation, it may indicate excessive gear backlash from internal wear. Have the gearbox inspected if the sound is progressive.

Probable Cause: Майлау материалы жеткіліксіз немесе майдың дұрыс емес деңгейі

Recommended Action: Drain and inspect oil for metal particles. Refill with correct grade. If noise persists after oil change, bearing or gear inspection is required. Contact support for rebuild guidance.

Probable Cause: Operating beyond rated horsepower or duty cycle

Recommended Action: Check oil level and grade against the specification. Clean all debris from the housing exterior — especially the cooling fins. If the self-cleaning filter system is being operated at or above the gearbox’s rated power, reduce forward speed or PTO load. Consider upgrading to synthetic gear oil for improved thermal performance.

Probable Cause: Майдың шамадан тыс толтырылуы ішкі қысымның жоғарылауына әкеледі

Recommended Action: First, check and correct the oil level — overfilling is a surprisingly common cause of seal leaks. Clean or replace the breather cap. If oil level is correct and breather is clear, the seal has worn and should be replaced using our seal kit.

Our Automatic Self-Cleaning Filter gearbox is rated for 3,000 to 5,000+ operating hours with proper maintenance. Many customers in intensive Australian operations report achieving 5,000+ hours before requiring any internal service. Key factors affecting lifespan include oil change frequency, operating load, and environmental conditions.

For most Australian climates, SAE 80W-90 EP gear oil meeting GL-5 specification is ideal. In tropical regions with sustained high temperatures, we recommend 85W-140. For southern regions experiencing cold winters, synthetic 75W-90 provides better cold-start protection. Check the oil specification card shipped with your gearbox for the definitive recommendation.

Routine service (oil changes, seal replacement, bearing inspection) can be performed on-site with standard tools. For major rebuilds, we supply complete overhaul kits containing all bearings, seals, and gaskets. Detailed service manuals and video guides are available for download from our support portal.

Yes — every purchase includes access to our engineering support team for installation guidance, troubleshooting, maintenance advice, and parts ordering. Support is available via phone, email, and our online contact form. There is no charge for technical support during or after the warranty period.

We accept bank transfer, credit card, and purchase orders from established accounts. For large orders, we offer 30-day payment terms subject to credit approval. Orders can be placed through our website, by email, or by phone. Pro-forma invoices are available for pre-payment arrangements.

Our gearboxes are mechanical components and contain no substances that would affect organic certification. However, the choice of lubricant should be considered — we can recommend food-grade and biodegradable gear oils that are compatible with organic farming standards in Australia and internationally.

Yes — we ship to every postcode in Australia, including remote and regional areas. We use experienced agricultural freight carriers who understand the urgency of seasonal equipment needs. Express shipping is available for emergency breakdown situations, and we maintain stock for immediate dispatch of popular models.

Each gearbox is drained of shipping oil, wrapped in VCI (Vapor Corrosion Inhibitor) film, and crated in a sturdy plywood box rated for international freight. This packaging protects against moisture, impact, and corrosion during transit — even for shipments to remote Australian properties via road freight.

The gearbox is specifically designed for the dynamic and impact loading characteristic of water filtration applications. Case-hardened alloy steel gears absorb repetitive shocks, while the optional overload protection (shear bolt or slip clutch) safeguards against catastrophic overload events. The bearing selection and housing rigidity are both matched to self-cleaning filter system load profiles.
