Window Lift Gear Replacement
and Installation Instructions |
|
Oct 2014 Rev 1.
Congratulations. You have purchased
one of the finest replacement parts made for your Chrysler 300.
John Grady has designed and manufactured new gears for the
1960-1964 Chrysler power window motor units.
If you choose to replace your gears yourself, please follow these instructions as it will ensure that you install
the gears properly on your gear boxs.
If you choose to have someone else do the work, or have any questions on
these procedures,
contact Jamie Hyde Jamie.hyde@optimation.us
or 585-465-0067 for assistance.
Please note these gears are
non returnable and can be damaged if you attempt to install them
without following these instructions.
The pictures below show the difference in early and late.
Read these instructions from start to finish before you attempt to replace the gears.
Obtain the proper Factory Service manual for your car to remove the motor and gear box from the car. Be careful as the regulator has a spring and can severely injure your fingers if you attempt to remove the regulator from the door. I removed just the motor and gear box with the window all the way up. This way the spring in the regulator holds the window up. No need to index the window in any location. I did this on my J but your model could be different.
Box with motor removed, notice the casting numbers, if you are doing more than one gear box do not mix up castings with different numbers.
