Truck Transmission Remanufacturing Process

All worn gears, clutches and sealing components of remanufactured truck transmission replaced with OEM-grade spares, passing full shift cycle testing to eliminate gear slipping under heavy cargo loads.

Details of Truck Transmission Remanufacturing Process

Step 1: Gearbox Receiving & Pre-Disassembly Inspection

Drain residual gear oil, inspect shell cracks, oil leakage, shift mechanism damage and abnormal noise records, mark model numbers to make overhaul plans.

Step 2: Full Internal Disassembly & Component Classification

Completely split clutch housing, gear housing, all shafts, gears, synchronizers and shift forks; sort all bearings, gaskets and sealing parts separately.

Step 3: Multi-Stage Deep Degreasing & Impurity Cleaning

All metal gear parts pass chemical oil removal, high-pressure flushing and ultrasonic cleaning to clear metal powder, gear oil sludge and rust.

Step 4: Crack Detection & Gear Wear Measurement

Detect gearbox housing cracks via magnetic flaw detection; measure gear tooth surface wear, shaft bending and synchronizer clearance. Replace severely worn gears and deformed shafts with new parts.

Step 5: Precision Correction & Surface Repair

Straighten bent transmission shafts, grind gearbox mating surfaces, repair minor housing deformation to restore assembly flatness.

Step 6: Full Renewal of Worn & Sealing Parts

Replace all bearings, synchronizer assemblies, oil seals, gaskets, shift fork bushings and clutch friction plates with brand-new matching spare parts.

Step 7: Layer-by-Layer Standard Assembly & Gap Calibration

Assemble shafts, gears and synchronizers step by step with OEM standard torque; calibrate shift clearance and gear meshing clearance repeatedly.

Step 8: Static Air-Tightness & Shift Function Test

Fill gear oil for static sealing test; repeatedly shift all gears to verify smooth shifting without jamming, jumping or slipping.

Step 9: Dynamic Bench Simulation Load Test

Install gearbox on dedicated transmission bench to simulate long-distance heavy-load shifting cycles; test shifting stability and load-bearing capacity under high temperature, record all test data.

Step 10: Anti-Rust Coating & Final Quality Archiving

Clean exterior residual oil, spray anti-corrosion protective paint; complete final overall inspection, sort all overhaul records into English test files before delivery.
