Product Description

WG9925821031 Cab Lifting Motor Assembly is installed in the hydraulic cab tilting system of SINOTRUK HOWO A7 and HOWO T7H heavy trucks. The motor drives the hydraulic mechanism to tilt the cab during engine maintenance, transmission inspection, and daily fleet servicing operations.

Motor overload, carbon brush wear, bearing seizure, connector oxidation, or hydraulic resistance may cause unstable cab lifting, slow tilting speed, abnormal noise, or lifting failure during maintenance operation.

This cab lifting motor assembly is widely used in export fleet maintenance, heavy truck cab overhaul, engineering vehicle repair, and commercial vehicle aftermarket service.

Product Overview

This cab lifting motor assembly is commonly used on SINOTRUK HOWO A7 and HOWO T7H high-roof cab platforms equipped with electric hydraulic cab tilting systems for long-distance logistics trucks, tractor trucks, and heavy-duty transport vehicles.

Common Field Failure Case

Case 1

Vehicle: HOWO T7H Tractor Truck
Mileage: 620,000 KM
Problem: Cab lifting became slow during maintenance operation
Root Cause: Internal carbon brush wear reduced motor output
Solution: Replaced WG9925821031 cab lifting motor assembly
Loss / Benefit: Restored normal cab tilting speed and reduced maintenance downtime

Case 2

Vehicle: HOWO A7 High Roof Truck
Mileage: 740,000 KM
Problem: Cab could not tilt during engine inspection
Root Cause: Motor bearing seizure caused hydraulic drive failure
Solution: Installed OE-standard lifting motor assembly
Loss / Benefit: Improved maintenance efficiency and reduced repair interruption

Case 3

Vehicle: Export Fleet Maintenance Project
Mileage: Fleet Service Application
Problem: Wrong mounting structure supplied
Root Cause: Different cab generation mismatch
Solution: Verified OEM number and side-mount dimensions before shipment
Loss / Benefit: Avoided installation failure and repeat export freight expense
