This article will walk you through the steps on how to grease the Da-Lite motorized screen's bearings.
At Life.Church, most of our campuses utilize Da-Lite motorized screens for center projector screens. Occasionally, these motors start to make a slight clicking noise when moving. This is just an indication that the motor bearings need to be greased.
Any time this is needed, please make the Central Tech Team aware by emailing [email protected].
1. Purchase White Lithium Grease:
Lowe's, Home Depot, Ace Hardware, as well as most hardware stores stock Lucas White Lithium Grease.
2. Find a a Pair of Gloves:
Find a pair of gloves; you may need a second pair just in case.
3. Find a Rag or Paper Towel:
Get a rag or paper towel to clean hands and any mess that may be made while performing this service.
4. Clear Both Sides for the Campus Lift:
Two parts need to be greased, one on each side. Make sure the area is clear for the lift to get to each side of the motor. Some stages are clear enough to pull the lift up close enough. Some are not and there may be a stage deck or two that needs to be moved in order to access the motors.
5. Raise the Lift on Each Side and Grease the Gear:
Each side has a part to be greased. The biggest thing is to ensure the grease does not get on the roller or the screen itself. The images below show which gears and how they are greased.
The other side is usually just one single point pictured below that needs to be greased very well.
6. Test the Screen:
The screen motor should be tested by going through the up and down cycles. However, it is not good to cycle too fast and burn up the motor or push it into protect mode. It is recommended to test by going up and down once, letting it sit for a few minutes, and then repeat. There should be a noticeable difference in noise after about ten cycles. There is no need to test ten times, but rather best about 3 times, and then let regular use of the screen do the rest.
