Since I haven't seen a ta04 thread before, I decided to put one up. But I have a problem with my ta04-trf. I have not seen a lot of people with this car, but I need some help with this problem, I am hoping to find someone here.
For those who are unfamiliar with the ta04, take a look at the following pic:
In the picture, you should observe a blue aluminum heat sink, the spur gear and the pinion gear. Attached to the spur gear is the drive shaft (which drives the front and rear belts) and attached to the pinion gear is the motor shaft. The motor is bolted onto the heat sink using 2x screws.
For anyone with a ta04-pro, ta04-r, ta04-s, that should be obvious.
Now, it is my intution that the drive shaft and the motor shaft should run parallel to each other inorder for power to be transferred efficently.
However, when I mount the motor to the heat sink by tightening the 2 screws, I find that the motor shaft is not parallel to the drive shaft. Its off by some abitrary angle. Although the pinion gear can be properly meshed with the spur gear, uneven wearing of the pinion and spur gears is severe.
This worries me also because endbell temperatures for me is hitting 70+ degrees celcius on a regular basis. I am beginning to think this misalignment factor is causing my motor to work excessively. I assure anyone who is reading the thread that I have tried many gearing combinations from 5.1:1 to 7.1:1 and the problem still exists. I run a 19T orion v2 motor.
I have tried to add shims to try and "pivot" the motor and help align the motor shaft to the drive shaft properly. But this has proved ineffective. Also, I reckon that if I shim excessively, the heatsink is rendered useless because it is not in direct contact with the motor.
I hope someone who has a ta04 and knows wtf i am talking about (i know i am not very good at expressing myself, but I don't have a camera and can't take any photos!) to help me out with this problem.
Is there anyone with a ta04 that has experienced a similar problem or know of a solution?
Thanks in advance!
