Toyota Training Video: Center Differentials

Postby YerRandO » Sun Jul 15, 2012 7:12 am

Original Toyota Canada training video for the introduction of the Celica and Camry "Full Time 4WD Manual Transaxle". Shows exactly how both the mechanical and viscous controlled center differentials work.

I copied this old VHS training video a few years ago while I was in school, they still use it to demonstrate viscous operation. Sorry it took so long to post it up, Enjoy

I swear all those old technical videos used the same music. Takes me back, though.

Thanks for posting it!

Wow!

These were fantastic, the music was so perfect!

I feel like taking my camry out and plowing through some snow now! :lol:

I wonder if I can retain the locking diff in it when I swap the engine...

What??? :twisted:

The early 165's had the electric button operated locking centre.
All later AllTracs/GT4s had the viscous centre.

For 99% of us, the viscous centre is better.

The locker in my camry definitely made the car feel more rear biased than my celica and I've heard that when completing the refresh of the viscous coupling fluid you get the same feeling.

Also, I think the really early 165's had a small lever that you pulled to engage the lock and later ones got a switch like this one:
165 diff lock switch.jpg


The switch + light thing you see in the video is more like what the corolla and camry received.

-Edit-

Also I don't know why in the video they tell you to drive with the light off and diff in "Free" mode, in the manual to my camry it says otherwise.

This system changes the center differential to the AUTO mode or the FREE mode by operating the control button.
If the front wheels and rear wheels are worn unevenly, the center differential control system does not function properly.
AUTO mode:
Use this mode in normal driving. The center differential is controlled automatically and the optimum driving condition can be obtained.
In this mode, the indicator light is on.
In case the indicator light either fails to come on or go out after pushing the "AUTO" button, ask your Toyota dealer to check the control system.
FREE mode:
Use this mode only when your vehicle needs to be towed or when the compact spare tire is insalled on your vehicle.
In this mode, the indicator light is off.


Maybe the camry has an automatic locker and it measures slip while driving and locks up when its detected where as the 165's had a true lock. :shrug:

-Edit-
Figured out what system the camry/automatics got here: viewtopic.php?p=426279#p426279

For those of you that have seen these videos and understand the drivetrain, please see my post here:
http://www.alltrac.net/phpBB2/viewtopic.php?f=4&t=45503&p=428170#p428170


It is about the possibility that the 4WD system is essentially a FWD until one of the front wheels slip. I'd like to know what you all think.
