UPPER BACK PANEL GEAR DRIVE
Proper function of the upper back panel limit switch is dependent upon proper condition and adjustment of the Upper Back Panel Gear Drive assembly.
Problems center around the following, so please read this list, and check to see if your gear drive appears to be in good condition.
- GEAR PLAY – using your hands, raise and lower the upper back panel to see how much play there is. Measure play at the end of the arm attached to the gear drive. If play exceeds 2.5 inches, your assembly probably does not work, or will stop working in the near future. Play of .5″ to 1.5″ is normal. Adjustments can be made to take some or all of this play out. Contact us if you need advice.
- REAMED OUT DRIVE ARM SHAFT – If your flap can be made to go up and down by hand; if it often slips back down after going up, the arm drive shaft may be reamed out. Contact us for advice on this repair. WE MANUFACTURE REPLACEMENT DRIVE SHAFTS
- CRACKED GEAR DRIVE BODY – Carefully inspect the gear drive housing for cracks. Once cracked, you will need a new gear drive housing. WE MANUFACTURE REPLACEMENT GEAR DRIVE HOUSINGS. Contact us on advice for this repair.
- DAMAGED WORM AND FLAT GEARS – The worm gears and flat gears inside the gear drive housing can wear out or break, causing non-function of the gear drive. WE HAVE THE WORM GEARS AND FLAT GEARS IN STOCK. Contact us on advice for this repair.
