The transmission clutch hub, No. 2 with Genuine Toyota OEM number 33362-36040 is a precision-engineered internal component within the 5-speed manual transmission (MTM) of Toyota's legendary heavy-duty vehicles. As the 2-3 gear synchronizer hub, it serves as the central locking mechanism that connects the shift sleeve to the main shaft, engaging the dog teeth to transfer torque during gear changes.
This Toyota transmission clutch hub is listed in Toyota parts catalogues for the following applications:
| Vehicle Model | Chassis | Engine | Production Period |
|---|---|---|---|
| Land Cruiser 70 Series | HZJ70, HZJ71, HZJ73, HZJ77 | 1HZ 4.2D diesel | 08.1999 - 08.2004 |
| Toyota Dyna / ToyoAce | BY34, BY43 | Various | Confirmed fitment |
| Hino 300 Series | Hino 300 (OLD) | 12LT HT125 WU340 14B | Compatible |
The synchronizer hub is subjected to the full torque of the engine and shock loading of every gear change. Common failure symptoms include:
