・1:1 OEM interchange, direct fit for Volvo A35D/A40D cargo hoist hydraulic system
11707967 main piston pump is manufactured strictly according to original drawing standards. All mounting dimensions, oil port layout and spline shaft parameters are fully consistent with VOE11707967 original pump. Direct replacement without pipeline or bracket modification.
・Heavy-duty reinforced structure for frequent dump & lift cycles
Specially built for repeated cargo lifting and dumping cycles on mining sites. Reinforced internal components resist shock load from heavy material unloading, extending service life under cyclic working conditions.
・Pressure-flow compound control, intelligent power matching
Built-in compound control unit automatically adjusts flow and pressure according to lifting load. It prevents power overflow, reduces engine load and protects hydraulic components from overload damage.
・FKM high-performance sealing system, reliable anti-leakage performance under high pressure
High-quality fluorine rubber seals resist high pressure and hydraulic oil aging. It effectively avoids internal and external oil leakage, keeps system pressure stable even during long-hour continuous lifting operation.

FAQ 

Q1: Which Volvo articulated dump truck models does VOE11707967 fit?
A1: It fits Volvo A35D and A40D articulated dump trucks. Please confirm OEM part number VOE11707967 before purchase.

Q2: What is the function difference between VOE11707967 main pump and 11707966 auxiliary pump?
A2: VOE11707967 is main pump for cargo box lifting. VOE11707966 auxiliary pump supplies oil for steering and cooling fan circuit. Two independent hydraulic power sources.

Q3: What symptoms will occur if VOE11707967 main pump wears out?
A3: Slow cargo dumping speed, insufficient lifting force, pressure drop under heavy load, unstable hydraulic pressure and abnormal rattling noise.

Q4: What preparation work should be done before installing this main pump?
A4: Clean the whole hydraulic circuit, remove metal debris, replace hydraulic oil and filter elements, inspect hoist cylinder and valve block, bleed air after installation.

Q5: What operation suggestions help to prolong the main pump service life?
A5: Avoid overloading the truck beyond rated capacity, do not repeatedly lift heavy cargo continuously, keep hydraulic oil clean and inspect pressure and oil temperature regularly.
