A complete installation or a Bunnings rollerdoor motor. Merlin garage door motor fitting. Chamberlain garage door motor. How to install a rollerdoor motor.
@@malayrojak The dismantling might have taken 10 minutes, but the full installation (one person only) took at least 90 minutes. Couldn't imagine life ever without this new remote door!
Awesome. Can you have motors for two separate doors, that work independently? I have a double garage with 2 single doors divided by a removable divider. I want to motorise both doors but want them to operate independently.
Great vid. My drum is offset inside by about 100mm i already got the extensions for the forks on the motor but how much do the forks have to go past the drum spokes to be safe? Is 30mm enough for a good grip? Will it cause too much cantilever force on them?
Thank you very much for this easy to follow video. I just finished looking at the chamberlain roller lift motor on the bunning's site. I am going to replace my garage tilt door with a roller door and am looking at around $1,000 - $1,200 for DIY door and motor installation. That is compared to $2,500 - $3,000 just for the roller door installation and an extra $800 for the motor fitting. My eldest son is a licensed electrician as well, so really looking at the DIY option.
Brilliant stuff man, I’m going down to Bunnings to get my door motor and fit it! Just one question, you mentioned the single screw through the door is used to stop theft, how does it work again?
If its the screw into the drum you are talking about, that just helps to avoid the door unrolling on itself if it hits an object n the way down and has to reverse back up
If the door is not pinned (on both sides, not just a single screw, he explains that he's already done the other side) to the drum, when the door is shut it's possible to lift the door up from the outside and it will rise up off the drum and open just enough for someone to get under it. Pinning it on both sides to the drum will prevent this.
My roller door has the drum wheels back inside the end of the door about 300mm so the folks on the opener won't reach the drum spokes. Can you get extension tubes for them?
My door does not have the round wheel that the fingers fit thought to drive the door up and down. Is it possible to get one of those wheels with holes for the fingers to pass through to drive the door up and down? Where would I find one?
Hi Stan, That sounds like a difficult job to retrofit a hub. The door would have to come down and be rolled out. I would try a local manufacturer for the hub if that’s doable
Recommend you replace that small step ladder with a Gorilla step ladder available from Bunnings ..far safer as it has a handle to maintain your balance if necessary.
It doesn't matter, left or right. Some doors may have a recessed hub on one side though. If sideroom is tight that's recessed side would be your best bet.
How do you measure door weight? I have a double roller door that had an older Merlin opener. Just lifting it with a spring scale gives a weight of 26kg. There are no added weights on the door.
Hi Stu, Using a luggage scale is a bit tricky. I generally just do it by hand. If your looking to replace a motor on a old heavy rollerdoor I would use a Merlin Silent drive Elite rather than the bunnings motor.
@@pinnaclegaragedoorsperth Thanks for your reply. Yes it does seem to add some drag and make the number a bit "iffy". Perhaps I should add maybe its not that old. The door is only about 15 years old(maybe that's old for a auto roller door?). I said old because its the type that has a large gear mounted to the door instead of the newer(?) two finger design with the gear inside the case. It only failed due the the gear being misaligned by the former owner/installer. Just to be sure you are talking about the MR855MYQ? One more question while I have you. The unit can go on either side of the door can't it? Its just that access to the unit to pull the release cord would be much easier if the new unit was on the other side of the door to the old unit.
@@stusue9733 the Mr855myq is the motor I suggest. The motor can go either side. The hub the motor fits to can be more recessed on one side in some brand doors. Something to look out for. Maybe add some tension to the spring if it's too heavy. We charge 770 to supply and install FYI
@@pinnaclegaragedoorsperth I'll check out the hubs. I can push the door up with two fingers on each hand so that's why I was questioning my 26kg figure. I might tension it up a little and add the door weight. Nice price but I am in eastern Vic so the commute would be a killer ;) Thank you for your time
@@killbot86 I would put it on then. The door may move side to side on the pole a little bit. Fix it and the door doesn’t run like it did before maybe adjust the collar position.
@@pinnaclegaragedoorsperth thank you for the advice. One more: my garage door is no longer balanced after attaching the weight bar (it was balanced before). Should I leave the weight bar off in that case?
You could try it with two people one holding the door and the other person slide in the motor on or if you have a stand you should put the door on the stand on the one side and remove the bracket inside the motor on
