Garage Door Openers
Sort of shed related, when your shed is the garage. The garage door opener for my section lift door shattered its drive cog the other day. The model is a Securalift GDO2V4. I've been in the house 15 years and goodness knows how long it has actually been installed. I've just started to look at it and try and find a spare part. The main cog is a 75mm worm drive nylon thing. It looks like a spare is available for $68 online. I've had a look at the mounting and it looks like it might be fairly straight forward to replace, hopefully the shaft is held in place by circlips that can be removed easily and doesn't need a gear puller or other exotic tool to get at.
I think the whole thing would have to be dismantled and taken off the ceiling to work on. I suspect a service person would charge up in the $100s to do the work.
I then see Bunnings has new garage openers starting at around $200. So my question is, has anybody been down this path before and can offer advice on whether it is an easy job to replace the drive cog? I don't want to buy the part then find I destroy something else trying to dismantle to replace it. Alternatively would I be better off just replacing the whole unit with one of the Bunnings $200 jobies?Franklin

If you have been there for 15yrs and it was there even before that I would suggest that once you start fiddling with it other problems will soon arise.
You can get reasonable openers new for $350 approx and a warranty as well
My thoughts FWIWThe person who never made a mistake never made anything

I've found a manual online for a slightly different version that includes an exploded parts diagram. Looks doable. Also having the install instructions from the manual is a great help, I didn't realize the unit can pivot down to the ground on the control tube, but that now makes sense looking at it! Also I now have some idea what the buttons on the control panel are for. I've never had to touch them in 15 years!

Another option is to get a new one printed in 3D. I have been getting a few done here for different old pieces of electrical gear.

Can't imagine any one printing one for less than $68.00

Fuzzie I have two tilt a door openers on the house. The one that is used most did the main cog. Finished up replacing it completely. The guy who came and looked at it said the main problem is that the shaft on which the cog is mounted also eats out its bearing/sleeve top and bottom. It was going to cost an arm and a leg to get it rebuilt. Just something to be aware of.

Ah Ross, thanks! This is the sort of info I was hoping for. I can see the shaft is seated in some sort of bronze looking bushings top and bottom. I can happily just lift the door manually as it is my workshop and doesn't really need a remote for garaging the car. I think I'll start by just taking the thing apart and having a look to see if everything else looks in reasonable shape. If so I can go ahead and order the part and refit at leisure, or consider a replacement.
Cheers,Franklin

Depending on how much use your garage door motor has had, I'd say its time for a new one anyway. 15 years is a good innings for something (in my case) that gets used every day and controls the largest door in my house.
Pretty soon your electrics will pack up and you'd be kicking yourself why you didn't just replace the entire unit.

All fixed! A local Garage Door factory were happy to sell me a replacement gear wheel for $45. I had to wait until they came back from Xmas break yesterday. No problem getting the shaft out. The opener is so old it uses limited electronics and a mechanical doover on the end of the shaft to wind a trigger up and down between micro switches to set the open and close limits. It was a bit tricky to get the doover back on with the new gear wheel engaged with the motor.
The hardest thing about the whole exercise was getting the bike chain off the cogs to start with and getting it back on at the end!Franklin

Same issue. I went for several years manually opening and closing the garage door after no one would repair it. Eventually, we replaced the door completely.
