Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC
I bought a replacement gear for the drive/worm gear element. The instructions said to use a pin and hammer to remove the gear. I've hit the pin element very hard several times but it doesn't budge. Any suggestions on how to remove this pin?
Find a c-clamp large enough to press the pin out. The only alternative is to disassemble the entire gear and use a hydraulic press. The problem with roll-pins and 'keepers' is that they are meant to fit tightly, and, like gears on auto axles, are pressed into place at the factory. Unfortunately, the average consumer doesn't have a large industrial facility in the backyard, so improvisations must be made. C-clamps, or even an appropriate GEAR PULLER may do the trick.
