Lifter and Operation Assembly: The primary housing and framework containing the internal mechanisms and providing structural integrity.
Lifting Arm Assembly: The core component directly responsible for raising and lowering attached implements via the three-point linkage.
Inner Lifting Arm: Works in conjunction with the main lifting arm assembly, likely providing additional support or specific force transmission points within the linkage.
Lifting Shaft: The central rotating shaft that transmits torque and movement to actuate the lifting arms.
Lifting Shaft Sleeve B & Shaft Sleeve (Multiple): Precision bushings or bearings supporting the lifting shaft and associated pins, ensuring smooth rotation and reducing wear. Critical for alignment and longevity.
Lifting Arm Pressure Plate: Applies force or acts as a bearing surface against the lifting arm assembly during operation, likely involved in maintaining alignment or absorbing thrust.
Piston Top Rod: The rod extending from the hydraulic piston, directly transmitting the hydraulic cylinder’s linear force to the lifting mechanism (likely connected to the lifting arm or cam).
Oil Outlet Pipe: The conduit directing hydraulic fluid out of the assembly after performing work, returning it to the tractor’s reservoir or other circuits.
Hydraulic Outlet Pipe Joint: The connection point securing the oil outlet pipe to the assembly housing, incorporating seals.
Oil Conveying Pipe Nut: Secures hydraulic pipes or fittings within the fluid transfer system.
Plug: Seals access ports or unused openings in the hydraulic circuit.
Adjusting Valve Solenoid Handle: Operator interface (likely manual override or control) for an electrically actuated (solenoid) valve responsible for adjusting hydraulic flow or pressure, enabling fine control over lift/lower functions.
Intercepting Valve Adjusting Rod: A rod mechanism used to manually set or calibrate the position or preload of an intercepting (likely shut-off or flow control) valve within the hydraulic circuit.
Intercepting Valve Limit Plate: A physical stop or guide plate that restricts the travel range of the intercepting valve or its adjusting rod, ensuring safe and correct operational limits.
Cam: A shaped component that converts rotary motion (likely from the lifting shaft) into controlled linear motion, potentially actuating valves or other internal mechanisms based on the lift arm position.
O-Ring & O-Seal Ring (Multiple): Essential elastomeric seals located at pipe joints, plugs, sleeves, and valve interfaces to prevent hydraulic fluid leaks and maintain critical system pressure. Vital for efficiency and preventing contamination.
Hexagon Head Bolts, Full Thread, Grade C: High-strength fasteners used for critical structural connections (e.g., securing the housing, pressure plates, valve bodies). Grade C denotes specific tensile strength for demanding applications.
Bolt (Multiple): General-purpose fasteners used for various internal component attachments.
Washer 10 & Washer (General): Distribute load under bolt/nut heads, prevent damage to surfaces, and ensure secure clamping. Washer 10 specifies a particular size.
Pin (Multiple): Hardened pins providing pivotal connection points for linkages, arms, or levers within the assembly, enabling necessary articulation.
Shaft Sleeve (Multiple): See point 1; crucial for supporting rotating shafts and pins, reducing friction and wear.
