708-1U-13411 Hydraulic Pump Cam Rocker supports piston-pump internal motion control for B2B excavator parts repair, rebuilding, and wholesale sourcing.
The 708-1U-13411 Hydraulic Pump Cam Rocker YNF19175 is an internal mechanical component used in compatible hydraulic piston pump assemblies. Within the pump mechanism, the cam or rocker structure participates in controlling the working geometry that allows piston movement and hydraulic displacement to be produced during shaft rotation.
Unlike an engine rocker arm, this component belongs to the hydraulic pump internal rotating and displacement mechanism. Its working surfaces must interact correctly with the corresponding pump components during operation.
When a hydraulic pump is rebuilt, the cam should be inspected for scoring, abnormal surface wear, deformation, contact marks, and dimensional deterioration. For professional B2B buyers, the 708-1U-13411 pump cam should be matched by part number, pump model or nameplate, physical profile, mounting surfaces, dimensions, and removed-part photos. Accurate identification helps reduce incorrect repair kits, repeated pump disassembly, workshop delays, and unnecessary freight costs.

Q: Is this an engine rocker arm?
A: No. It is an internal hydraulic pump component used in a compatible piston pump mechanism.
Q: When is the pump cam normally replaced?
A: Replacement may be required when abnormal wear, scoring, deformation, or damaged contact surfaces are found during pump rebuilding.
Q: Can this part be ordered for hydraulic pump overhaul stock?
A: Yes. It is suitable for hydraulic repair workshops, pump rebuilders, dealers, and B2B spare-parts inventory.
YNF Machinery supplies 708-1U-13411 hydraulic pump cam rockers and related internal pump components for hydraulic repair workshops, excavator service businesses, machinery dealers, wholesalers, rebuilders, and international importers.
The YNF19175 pump cam is a precision-fit internal repair component. For professional buyers, matching should not be based only on general appearance. The reference number should be checked together with the hydraulic pump model, pump nameplate, working-surface profile, mounting geometry, and dimensions before quantity purchasing.
Buyers can provide the 708-1U-13411 part number, pump model, required quantity, nameplate photos, removed cam dimensions, working-surface photos, and complete pump information for fitment checking.
Cylinder blocks, valve plates, piston assemblies, retainers, shafts, bearings, servo pistons, regulators, seal kits, and other hydraulic pump rebuilding parts can also be consolidated into the same order for more efficient B2B procurement.
