Oil pump assembly is the heart of the lubrication system, drawing oil from the sump and delivering it under pressure to all moving parts. It is a critical element of the part.
Steel ball8.000 G200b GB308 acts as a check valve or pressure relief element within the pump. Its precise diameter ensures consistent regulation of oil pressure in the part.
End plate gasket seals the interface between the pump housing and cover, preventing oil leakage. It is a critical sealing element of the part.
Flat washer distributes load under fasteners, protecting surfaces and ensuring even clamping in the part.
Hexbolt is a standard external hex fastener used to secure the pump and pipe brackets. It provides reliable clamping force in the part.
Papergasket seals the inlet pipe flange, preventing oil seepage and maintaining system pressure in the part.
Hose assembly is a flexible or rigid tube that conveys oil between the pump and the transmission galleries. It is an integral part of the part.
Hollowbolt is a fluid‑passage bolt that allows oil to flow through its centre while providing a strong mechanical connection in the part.
Outputoil assembly is the pipe that routes pressurised oil from the pump to the main oil gallery. It is a key delivery path in the part.
Seal washer is a composite sealing ring used at fluid connections to prevent leaks under high pressure in the part.
Tube is a rigid steel pipe that carries oil inside the transmission housing. It is precisely bent to clear moving parts in the part.
Shealth is a protective bushing or sleeve that supports the tube and prevents chafing against the housing in the part.
Inputoil assembly is the pipe that delivers oil to the input shaft bearing area. It ensures proper lubrication of the front bearings in the part.
Filterbracket is the mounting bracket that holds the oil filter in place, ensuring easy access for replacement in the Oil pump and pipe component.
Oring26500850GB3452.1 is a standard O‑ring that seals the filter or tube connection, preventing external leaks in the Oil pump and pipe component.
Oring26507100GB3452.1 is another O‑ring used at a different connection point, ensuring complete sealing integrity of the Oil pump and pipe component.
Endplate is the cover that closes the filter housing, providing access for maintenance and sealing the filter cavity in the Oil pump and pipe component.
Springwasher prevents fastener loosening under vibration, maintaining joint integrity in the Oil pump and pipe component.
Glue (thread‑locking compound) is applied to critical fasteners to prevent loosening and ensure long‑term reliability of the Oil pump and pipe component.
