Synchronizer Hub 33361-36030 For Hino 300 Series 12LT HT125 WU340 14B Manual Transmission
Product Overview

The synchronizer hub (OEM: 33361-36030) is a critical internal component of the 5-speed manual transmission (MTM) used in Hino and Toyota commercial vehicles. This hub serves as the central locking and torque-transfer element within the synchronizer assembly, enabling smooth gear engagement by matching speeds between the hub and gear before locking them together.

Additional compatible platforms: Toyota Coaster, Toyota Quick Delivery, Toyota Dyna 200 / ToyoAce G25

Important Note: This hub is specifically for the 5-speed manual transmission (MTM) and serves as the No. 1 clutch hub (first/second gear synchronizer hub). Always verify your transmission type and original part number before ordering.
Failure Symptoms & Diagnosis

The synchronizer hub withstands full engine torque and shock loads during gear changes. Common failure symptoms include:

Symptom Diagnosis
Difficulty engaging first or second gear Worn hub teeth - immediate inspection required
Grinding noise when shifting Worn hub or synchronizer ring - replace hub and inspect sleeve
Transmission pops out of gear under load Worn hub teeth or shift fork - replace hub
Excessive play in gear lever Worn internal splines on the hub
Metallic particles in transmission oil Worn hub teeth or bearings - requires disassembly and inspection
Features & Benefits
Precision Engineering

Specifically designed for 5-speed manual transmissions with 54T/46T gear configuration matching factory specifiions.

High-Strength Construction

Manufactured from SCM415/SAE 8620 alloy steel for optimal surface hardenability and core toughness.

Advanced Heat Treatment

Carburizing and quenching process delivers HRC 58-62 surface hardness with impact-resistant core.

CNC Precision Manufacturing

Produced using CNC turning, milling, internal spline broaching, and precision grinding for accurate fitment.

Matched Component System

Designed to work with 33364-36080 shift sleeve as a matched pair for optimal performance.

Damage Prevention

Prevents secondary damage to shift sleeve and gear teeth, avoiding costly transmission rebuilds.

Quality Control

Each batch undergoes comprehensive verifiion including:

  • Material composition analysis (SCM415/SAE 8620 grade confirmation)
  • Surface hardness testing (HRC 58-62 verifiion)
  • Tooth profile accuracy measurement via CMM
  • Internal spline dimension verifiion
  • Concentricity and runout measurement
  • Surface finish analysis
  • Heat treatment microstructure examination

Certifie of conformance with batch test data available for wholesale orders.

Installation & Maintenance
⚠️ IMPORTANT: Transmission disassembly required. Professional installation by qualified transmission specialist strongly recommended.

Critical Installation Notes:

  • This is the No. 1 clutch hub (first/second gear synchronizer hub)
  • Designed to work with 33364-36080 shift sleeve - replacing both components together is recommended
  • Inspect synchronizer rings, shift fork, and gear engagement teeth for wear
  • Replace transmission oil with correct grade (GL-4 or GL-5) after reassembly
  • Check and adjust shift linkage after installation
  • Refer to Toyota or Hino workshop manual for complete procedures
Packaging & Supply
  • Packaging: Sealed in anti-rust packaging, foam-lined carton
  • Lead Time: 3-7 working days (stock orders); 15-25 days (production orders)
  • Minimum Order: 1 piece
  • Shipping: FedEx, UPS, DHL for samples; sea freight for bulk orders
  • H/S Code: 8708.40

Matching components (shift sleeve 33364-36080, synchronizer rings, bearings) also available for complete transmission rebuilds.

Quick Summary

The synchronizer hub 33361-36030 is an OEM-spec replacement for the No. 1 clutch hub in 5-speed manual transmissions of Hino 300 Series and Toyota Dyna vehicles. Features 54T/46T gear configuration, SCM415/SAE 8620 alloy steel construction with carburizing heat treatment (HRC 58-62), and designed to work with 33364-36080 shift sleeve.

Before ordering: Confirm your vehicle's chassis code and transmission type (5-speed manual).
