OTTO PLP Head Valve Plate (valve plate) for Hitachi UH07 / UH07-7 / UH083 Excavator - the head valve at the rear of the rotating group in the HPV125B main pump, supplied as Handok Hydraulic (Korea) part 066730. The lapped running face seals the piston group against the intake and delivery ports, so a scored or stepped plate costs flow and heats the oil. Renew it together with the pistons and shoes to bring main pressure back to specification. Inspected before shipment, 3-12 months warranty options.

This Arm Seal Kit with part number 4699081 is a full set of hydraulic sealing parts specially designed for Hitachi EX1200-6 excavator arm cylinder. It contains all required seals and gaskets for arm cylinder overhaul, to stop oil leakage, maintain stable hydraulic pressure and restore normal arm movement of the excavator. It is a direct replacement kit for aged, cracked or leaking original seals.

This HMGF68 6 slot rotor is a core precision component for excavator travel hydraulic motors. The standard 6-slot structure provides precise assembly tolerance, ensuring smooth hydraulic power conversion during equipment operation. It effectively fixes common travel motor failures including slow movement, walking jitter and insufficient driving force, and stabilizes the overall working performance of excavator travel systems.

The OTTO 708‑3M‑04161 Swash Plate Assembly is a core internal component for the main hydraulic pump of Komatsu PC190LC‑8 excavator. This precision‑machined swash plate controls the piston stroke to adjust pump displacement and hydraulic oil output flow. It is manufactured from high‑strength alloy steel with hardened friction contact surface, matched with precise bearing mounting surfaces, to maintain stable angle adjustment under high‑pressure, heavy‑load continuous working conditions. Strict dimensional tolerance ensures good fitting with pump pistons, shoes and regulator components.

This OTTO heavy-duty high-pressure hydraulic hose with OEM part number 201-1260 is a core fluid transmission component matched exclusively for Caterpillar C9.3 engines and CAT 336E large mining excavators. Assembled with integrated OEM standard fittings at both ends, it transports high-pressure hydraulic oil between main pumps, control valves and hydraulic cylinders, enduring continuous ultra-high working pressure, frequent bending and violent machine vibration during all-day quarry excavation, heavy truck loading and large-scale infrastructure construction. Its superior flexibility allows neat routing in narrow engine and chassis gaps without sharp bending damage.

This OTTO high-quality K3V63DTP hydraulic pump regulator is the core load-sensing control valve matched for Kawasaki K3V63DTP main hydraulic pumps, widely applicable to Volvo and Kobelco medium excavators. It precisely adjusts pump displacement and hydraulic output according to real-time load demand, realizing flexible boom, arm and bucket operation while maintaining stable system working pressure.

This OTTO XP00000363 O-RING Kit is premium excavator maintenance fitting parts, specially manufactured for Hitachi excavator systems. It provides tight sealing for hydraulic and pipeline joints to effectively prevent oil leakage, air intake and pressure loss.
