Products Description
WG9719820001 cab lifting pump is mainly applicable to Sinotruk Howo heavy‑duty trucks. It is the core manual hydraulic component of the cab tilting system, providing hydraulic force to tilt the cab forward for engine service. It fits cargo trucks, dump trucks and tractor units used in logistics, construction and mining scenarios. All mounting positions, oil inlet and outlet ports are manufactured according to original OEM drawings, direct replacement without modification. If you are not sure about vehicle compatibility, send us your truck model information, we will check fitment for you quickly.

Quality Comparison
| Feature | WG9719820001 (OEM Standard) | Ordinary / Low‑Quality Cab Lifting Pumps |
|---|---|---|
| Internal Piston Assembly | Precision‑machined piston, stable pressure output | Rough machining, pressure is unstable during pumping |
| Housing Quality | High‑strength cast metal housing, anti‑deformation | Thin casting, easy deformation under high pressure |
| Sealing Performance | High‑quality oil‑resistant seals, anti‑leakage | Poor‑quality seals, easy oil seepage after short‑term use |
| Working Performance | Smooth cab lifting, can hold cab position steadily | Slow lifting, cab drops by itself, insufficient pressure |
| Service Life | Long service cycle under frequent manual operation | Fast internal wear, easy failure in short time |
Working Principle Introduction
How WG9719820001 Howo cab lifting pump works:
‑ Manual Input: Operate the hand lever to drive the internal piston of the pump.
‑ Oil Suction: Hydraulic oil is drawn from the oil reservoir into the pump chamber.
‑ Pressure Generation: Piston movement compresses hydraulic oil to generate high‑pressure oil flow.
‑ Cab Tilting: High‑pressure oil is sent to the cab tilting cylinder to push the cab to tilt forward.
‑ Position Holding: Good sealing keeps the cab locked at lifting position for safe maintenance work.
Actual Application Scenarios
This heavy‑duty cab lifting pump adapts to various harsh working environments:
Long‑distance Logistics: Used for routine engine maintenance of Howo long‑haul trucks, ensures safe cab tilting for inspection and repair work.
Construction & Mining: Suitable for engineering and mining vehicle field maintenance, works reliably in dusty and rough‑site conditions.
Export Proven: We supply this cab lifting pump to overseas repair shops, fleet companies and auto parts distributors. It performs stably in different climate regions, with low failure rate and high customer recognition.
Product Testing Standards
Every batch of cab lifting pumps undergoes strict factory inspection. We complete hydraulic pressure test, oil leakage test, load‑holding test and mounting dimension inspection. All unqualified products with pressure deviation, oil leakage, dimensional error will be eliminated. Strict testing guarantees safe and reliable cab tilting performance after installation.
Installation Tips
1.Clean mounting surface and oil pipe connectors before installation.
2.Inspect new pump oil ports and sealing parts for damage or deformation.
3.Align mounting holes, fasten bolts evenly, avoid over‑tightening to prevent housing damage.
4.Connect oil hoses to correct ports, fill with specified hydraulic oil.
5.Operate hand lever to bleed air from tilting system after installation.
6.Test cab lifting and lowering function, check for oil leakage and confirm cab can hold position steadily.
Frequently Asked Questions
Q1: Can you confirm fitment by truck model?
A: Yes. Just send us your truck model details, our staff check matching condition and reply you within 24 hours.
Q2: Is the WG9719820001 cab lifting pump easy to install?
A: Absolutely. It fully matches original mounting size and oil port position, direct replacement without cutting or modification.
