• **Heavy-duty PTO assembly tailor-made for Volvo D12D engine, perfectly matched with EC360/EC460 pilot pump**
11128611 power take-off assembly is custom designed for Volvo D12D engine. It transfers engine power steadily to pilot pump. Reliable power output ensures normal operation of pilot hydraulic system during heavy-load excavation and rock breaking work.
• **Precision forged drive gear, stable torque transmission and low vibration**
Alloy steel drive gear adopts precision forging and gear grinding process. Gear meshing is smooth under variable torque condition. Power loss is minimized to guarantee stable supply of pilot control power.
• **High-strength cast alloy housing with stress relief treatment, excellent crack resistance**
Cast alloy housing after stress relief annealing eliminates internal residual stress. It can resist continuous vibration and torque impact in quarry sites. The housing is not easy to crack, slowing down wear of internal gear and bearing components and extending service life.
• **Optimized flange sealing structure & upgraded FKM gasket set, good anti-leakage & high temperature resistance**
Optimized flange contact surface design reduces deformation risk. FKM sealing gaskets deliver outstanding high-temperature and oil resistance. It effectively prevents engine oil leakage, avoiding premature component wear caused by oil contamination, minimizing unexpected machine downtime.
• **Reliable power transfer to protect engine and pilot hydraulic system**
This PTO assembly provides stable torque for pilot pump. It maintains pilot hydraulic system working normally, preventing pilot pump failure and engine damage caused by PTO malfunction, ideal replacement for overhaul and daily maintenance of Volvo EC360/EC460 excavators.

FAQ 

Q1: Can this 11128611 PTO fit EC380 excavator with D13 engine?
A1: This PTO is designed for D12D engine on EC360/EC460. EC380 equipped with D13 engine has different mounting flange and gear ratio. It cannot be interchanged. Confirm engine model before ordering.

Q2: What preparations are required before installing this PTO assembly?
A2: Drain engine oil, clean the engine block mating surface thoroughly. Check crankshaft end play and inspect the pilot pump for wear. Damaged pilot pump may overload the new PTO gear.

Q3: What causes oil leakage on the flange face after PTO installation?
A3: Common causes include uneven mating surface, loose mounting bolts, damaged sealing gasket or over-tightened bolts leading to housing deformation. Disassemble and check the sealing surface and gasket.

Q4: Can this PTO be used for modified hydraulic auxiliary drive besides driving pilot pump?
A4: It is originally designed to drive the original pilot pump. Modifying to add extra hydraulic load will exceed rated torque, which will lead to gear breakage and void the warranty.

Q5: How should we store the PTO if installation will be delayed for several months?
A5: Keep it in dry warehouse, coat anti-rust oil on gear and flange surface, seal all ports with protective covers. Avoid stacking heavy goods on the housing. Periodic anti-rust maintenance is recommended for long storage.
