Motor Install Gear Mesh???

[skullking]

Just wondering what kind of tricks there are for switching out the motor and setting the gear mesh. I had to make a LOOOONG Hex wrench to switch out the motor. But setting the gear mesh is rather hard when there is grease on everything. Any Tricks????

When setting mesh I tend to snug up one of the two screws and then try to rotate the gears together while watching. (by this I mean I rotate the motor using the snug screw as a fulcrum)

I tend to mesh and unmesh the gears a few times to get an idea of how far the teeth engage till they bottom out. Then I just try to set it where it seems that 90% of the teeth are together.

Yeah it seems to be a "I hope I got it" kinda Thing.

I find it easy to set up the pinon/spur gear mesh.

I have long handled Allen wrench tools that do the trick.

Snug up the screws, one hand on the tool the other on the motor, look down the access hole with some light behind you, move motor till the mesh looks good, tighten screws, recheck for binding, done.

ya i had to make a real..... long allen too!!!
i read some where that you should put in the motor
BEFORE you put on the battery tray ( makes sence to me)!!
i just did as one of the post's said, i kind of tightened one
screw to work off of. i used a flashlight (in my mouth) and
wiggled the motor back and forth in the gears ,untill it looked
like it had the correct mesh. kinda like standing on a basketball
while rubbing your head and patting your belly!! not quite but .............

something like this will help in the future: http://www.telesightmagnifiers.com/catalog/i294.html

I just work it by feel, I snug both allen screws up but not tightened. Then I move the motor in while rolling the car (or turning the tires) ... at that time I'm listening for the right whine. Seems to have been working for me fine all these years.

I did mine by feel/sight but have set em up with the 'paper trick' before. Put a piece of paper between the pinion and spur, then push the pinion against the spur and tighten the motor mounts. The paper should give you enough space between the gears for a decent gear mesh. (remove paper before operating haha)

How did you get paper in the venom trans housing ?

[Bray D]

I didn't. I've used that on external pinoin/spur setups. I don't know why you couldn't with the creeper trans though.

Install the motor loosely and rotate the pinion away from the spur.
Cut a small rectangle out of paper, and place it between the pinion and spur by whatever means necessary (tweezers?)
Rotate pinion into spur.
Tighten motor.
Spin the drivetrain and remove the paper.
