Products Description
product key technologies
This SHACMAN steering hydraulic pump assembly (OEM DZ97319470117, ISM 1.25s) is a core vane‑type power steering component engineered for SHACMAN heavy‑duty commercial vehicles with ISM engine matching requirement. It converts mechanical power from engine gear drive into stable hydraulic pressure to lower steering resistance for drivers, delivering responsive, smooth steering feedback under full‑load, long‑haul and rough‑road operating conditions.
Manufactured with high‑strength cast‑iron housing, precision‑machined vanes and integrated pressure‑limiting valve structure, this unit suppresses internal pressure fluctuation, reduces running noise and improves sealing stability against high‑temperature hydraulic oil aging. Strict bench cycle tests are implemented during production to match original factory installation dimensions and gear transmission ratio, eliminating extra modification during replacement. It is widely stocked for global truck repair workshops, fleet maintenance centers and heavy‑truck spare‑part distributors, serving aftermarket replacement and overhaul projects for SHACMAN heavy trucks.

Product Selling Points
Consistent Hydraulic Performance Across Full RPM Range
Built‑in pressure‑limiting valve and precision‑tuned internal mechanics deliver steady pressure and flow output across the complete 600‑3800 r/min operating range of the DZ97319470117 steering hydraulic pump. It prevents pressure spikes and insufficient power‑steering assist triggered by fluctuating engine speeds. Whether executing low‑speed sharp turns or highway cruising, this SHACMAN power steering pump maintains predictable steering response for heavy‑duty trucks, boosting vehicle handling and driver safety.
01
Heavy‑Duty Build for High‑Load & High‑Temperature Working Conditions
Crafted with one‑piece high‑strength cast iron housing plus anti‑rust surface finishing, this SHACMAN steering pump assembly resists corrosion and mechanical vibration. Hardened alloy vanes serve as core internal parts, delivering superior wear tolerance and thermal resistance against long‑time hot hydraulic‑oil circulation. It minimizes common failure modes including internal component abrasion and joint oil leaks, effectively extending service life for ISM 1.25s heavy‑truck chassis.
02
OEM‑Spec Direct Bolt‑On Fit, Zero Additional Modification
Manufactured strictly to OEM DZ97319470117 and ISM 1.25s dimensional standards. Mounting footprint, gear drive ratio and oil‑port thread sizes fully match original factory components. Truck service technicians can complete direct bolt‑in swap without cutting, drilling or reworking. This drop‑in aftermarket spare part cuts down vehicle downtime and raises overall workshop repair efficiency for SHACMAN heavy‑truck servicing.
03
Optimized Hydraulic Structure for Low‑Noise Smooth Operation
Revised vane profile and internal fluid‑circuit design mitigate hydraulic turbulence and mechanical friction noise during pump operation. Compared with generic aftermarket steering pumps, this DZ97319470117 assembly runs smoothly with reduced operational hum. It avoids typical defects of cheap alternatives such as loud buzzing, steering jitter and intermittent assist loss, supporting stable steering‑system performance under real‑world road conditions.
04
Cost‑Efficient Aftermarket Spare Part for Mixed‑Condition Fleet Operations
Purpose‑built for SHACMAN heavy trucks equipped with ISM series engines, this steering hydraulic pump handles diverse harsh working scenarios: over‑the‑road logistics, mountain route hauling and site engineering transport. Low defect rates cut recurring repair expenses and frequent spare‑part turnover for commercial fleets. It stands as a reliable, budget‑friendly replacement solution for fleet maintenance and daily heavy‑truck overhaul.

FAQ
Q1: Which SHACMAN truck models can DZ97319470117 steering hydraulic pump assembly fit?
A1: It is specially developed for SHACMAN heavy trucks supporting ISM 1.25s engine configuration. Please double‑check original OEM part number and engine parameter before ordering; do not install it on non‑ISM‑matched chassis even if mounting holes look similar, or abnormal noise and insufficient assist pressure may occur.
Q2: What symptoms indicate that the steering hydraulic pump assembly needs to be replaced?
A2: Typical failure signals include obviously heavy steering effort especially at low‑speed turning, continuous whining noise from pump housing during engine running, hydraulic‑oil leakage at pump joint surface, unstable steering assist strength (alternating light‑heavy steering feeling). After confirming no pipeline blockage and oil shortage, you can arrange pump replacement.
Q3: Can I repair the old pump instead of buying a brand‑new DZ97319470117 assembly?
A3: Individual worn sealing rings can be replaced for minor oil leakage, but for worn vanes, deformed housing or internal pressure‑valve damage, field‑repair cannot guarantee long‑term stability. For heavy‑duty trucks undertaking cargo transport missions, whole‑assembly replacement is more recommended to prevent sudden steering‑system breakdown on the road.
Q4: What key points should I follow during installation and commissioning?
A4: Clean connecting pipelines thoroughly before installation to keep impurities out of hydraulic circuits. After finishing bolt fastening, fill in qualified steering hydraulic oil, run engine at idle speed, turn steering wheel from full‑left lock to full‑right lock repeatedly to exhaust air inside the system. Finally check oil level and all joints for leakage before formal road test.
Q5: What maintenance work helps extend the service life of this steering pump assembly?
A5: Use factory‑specified steering hydraulic oil only; avoid mixed‑use of different‑spec oil products. Inspect oil level and oil quality periodically, replace aging hydraulic oil on schedule. Prevent hydraulic‑oil contamination caused by damaged oil‑return filter. Do not keep steering wheel staying at full‑lock position for long time during vehicle operation.
