How to replace Stegbar Sliding Glass door roller wheels. Part 1

I saw how to do this on another RUclips video but I want to add more information and details into the repair. The glass door uses a RIGHT HAND and LEFT HAND WHEEL CARTRIDGE. I bought these from Bunnings.com.au .They were made by RollTrack and costs AUD$16.39 each.

Steps :
1) Place Glass Door flat on a table. Careful not to put pressure on the door lock/handle. Let it hang off the table edge.
2) Loosen the small screws on the top left and right of the Glass door.
3) Loosen and remove the small screws at bottom left and right of the Glass door.
4) Screw/tighten the the large screw that controls the wheel height. We want to make the screw head as close/flush to the Roller Wheel cartridge so that it can clear the tiny lip of aluminium at the corners of the bottom left and right of the Glass door.
5) Get a 60cm piece of wood and put it against the left aluminium frame. Use a hammer and tap the wood firmly to nudge the aluminium frame off the glass. 4-5 taps then shift location. Do the same on the right-side aluminium frame.
6) Once the left and right aluminium frame has moved enough allowing the Roller Cartridge screw to clear the "aluminium lip" at the corner left and right. Move the piece of wood to the bottom aluminium frame and give it 4-5 taps here and there until the bottom frame clears the left and right aluminium frames. If you have clearance, you can start pushing the cartridge out.
7) If cartridge is stuck, you can use a small piece of stick to push the cartridge out by hammering the small stick. Be careful not to bend the aluminium groove that the new cartridge will go into.
8) Insert new cartridge. Screw it tight so the screw head is flush and sits closely to the roller cartridge. We need to do this so the cartridge "clears" the tiny "aluminium lip" at the bottom corners of the Glass door.
9) Check the rubber seal is seated property on the glass.
10) Push frame against the seal and glass. Checking the rubber is not distorted. Redo if the rubber seal is not in correctly. You can use your finger to gently re-position the seal by pressing and sliding it up and down.
11) Once the glass and seal is seated and secured, we find the small screws and screw the bottom left and right of the Glass door.
12) Don't forget to tighten the top left and right screws of the Glass door.
13) This is important! Try to lower the wheels as much as you can. Turn anti-clockwise to loosen the adjusting screw. Sometimes the wheel doesn't seem to lower, in this case, you push in the screw and press down on the wheel to help lower it. Get the wheel as far inside the door so that it doesn't block the reinstallation of the Sliding Glass door. Look at the bottom edge of the frame, do you see any wheel jutting out. Try again until it is as low as you can get.
14) Check the frame does not have any protrusion caused by Security Door alarm sensors/shock detectors because they may make it difficult to reinsert the Sliding Glass Door. You may need to shift to a different spot away from the Alarm sensors and silicone seal.
15) Clean the tracks and frames. They may be full of dirt.
16) When Sliding Glass Door is in position, screw the adjustment screw clockwise to raise the wheel height. Do this until the Sliding Glass door closes properly and securely. The two guiding pins on the Sliding Glass Door lock may be blocking it.
The installation took me 5 hours because I had to go back to Bunnings four times because I bought the wrong wheels. I didn't realise I needed a LEFT HAND and RIGHT HAND WHEELS. Also I struggled to move the aluminium frame off the glass. The frame with the Door Lock was harder to budge. I tried pulling it off with my hands but I was impossible. My luck changed when I used a 60 cm scrap piece of pine and small hammer to tap the aluminium frame off the glass. The frame without the Door lock easily came off after a couple of hard taps. The frame with the Door lock was much tougher but I budged it out by 6mm so the Roller Cartridge Adjustment Screw just clears the bottom lip of the aluminium frame. Once I had clearance, I used the scrap pine to hammer the bottom frame off a little. Just enough for me to remove the old wheel cartridge and put it the new. The goal is not to dislodge the frame off the glass more than necessary to remove the old roller cartridge. If the frame comes off the glass entirely, it just means more work and time reseating the rubber seals and pushing the frames back together.

Just replaced left and right Stegbar cartridge rollers. Note I didn't loosen the frame.
Remove door and rest on floor so as to access rollers.
Using one hand clasp plastic end clips with a pair of long nose pliers so they are almost together and with your other hand knock the pliers with a hammer. The result will be the cartridge will slide down and away from its original position. Knock down about 30cm.
Next, wedge a piece of wood or a screwdriver handle next to the cartridge. The aim is to loosen the grip of the aluminium frame on the cartridge.
Pull out the cartilage with pliers.
Slide new cartridge in at 45 degrees so that the screw ridge fits into the hole in the frame.
At this point you will need to push and line up the cartridge male 'studs' with the female slot in the window frame. I put a little oil on to make next step easier.
Once lined up knock the cartridge with a block of wood and hammer or rubber mallet The stud and cartridge will lock into the slot/place.
Good luck!

Mariani, thank you for this. How did you remove the door off the track? Did you use suction handles for glass ?

[@tonynew3047]

Just lift the whole thing.

Thank you for this! even seeing the roller itself is helpful.
Stegbar are truly one of the worst companies on the planet. Pathetic designs and they don't provide any support for their older windows. They really should be forcefully shut down by the government or made to provide all replacement parts for their products (I can't get latches from them for my windows).

Yep - their replacement design for rollers etc is terrible. I would never have thought you have to actually break the frame away from the glass to fit them. For other companies you undo some screws some to replace.
