Adjusting Older Sliding Glass Door?

[D45]

I have an older (old) Marvin sliding glass door on the back of my house, that goes into the enclosed patio.....I looked all over and cannot find a model number

The locking mechanism works great and the quality is far superior to the cheap ole versions used in most new construction houses

I also love the 3 pin lock, as most are the cheap ole single loop arm

Anyways, what can I do to get the door to slide easier?

It slides decent, but I think it could move a lot better

Thanks!

There are either holes to access the wheel height adjustment or you will have to take it off the track and see what’s under there. You can lube the wheels with lithium grease as well to get it moving.
Picture 5 I think you can see the screw next to the white

Ya I would also say do a spray lube the track first and make sure is clean of debris too. I have a big Pella slider they are heavy doors but slides real easy

Lube can make a big difference. The wheels get dirty which make then hard to move. You will probably have to remove the door to adjust the wheels.

Ok, so what kind of spray lube?

I cannot even see the wheels to spray them down

I assume there will be wheels on top and at the bottom?

No wheels on the top.

Look for the plugs on the bottom interior side of the door.

Here is a video for you

You want a dry lube

A silicon based lubed probably be best though even WD 40 would help. Amazing what silicon spray can do for sticky rear sliding glass windows in trucks and on fiberglass bed caps.

Don't use spray lithium grease that will trap dust

Thanks for all the help!!

Its opening and closing MUCH BETTER now

I first vacuumed the track and then hosed it down with some spray lubricant......and actually used a small old toothbrush on the track channels. I got a lot of dirt removed

I spraying lube into both ends of the slider, where I think the wheels would be

I also found two plugs at the bottom, which are for the door track adjustment...….I also sprayed lube in these holes

Cleaned up all the excess and its pretty nice now

I will just have to keep this on my 3 month to do list

Marvin also sells the parts. I recently redid 6 sliding windows and 2 quad doors.

I usually replace the rollers as the bearings in them are probably on the way out. a flat file on the track rail to clean up any nicks and burrs helps a lot to

Also check to see if the upper track is sagging in the center. Mine is a bit. I was able to adjust the main door wheels to accommodate the decreased height but the screen door is out of adjustment so it's not quite as easy as I would like.

Sagging...…...that is a good idea to check

I have a very similar door. To lube it correctly, you will remove the plugs and see a #3 phillips screw in each hole. Those are for adjusting the door up and down. I don't remember which way you turn them, but I would imagine counter clockwise would wind them down. After you have them both adjusted all the way down the door can be removed from the frame (take caution when winding the last adjuster down, as the door can fall out).

Have some padded saw horses ready and set the door on them. You can now access the rollers on the bottom of the door. Removed them, flush them out very good with a solution of your choice, and grease them. I was able to inject pretty thick grease into the bearings of the rollers. Reverse removal process and BOOM!

If you call Marvin they can help you with the model. Marvin changed to a larger roller size around 2002. My doors have two trolleys for each door .... each door has two trolleys. Some doors came with SS.

My doors are 4 panels w/ the center two operating ... we really only use the left hand door on each set. So I ordered 4 of the trolleys -- the front trolley on each door gets the most ****. They also sell the weather strip between the doors ... and the washer for the lock.

Clean it all up and it's as good as new.

The sagging could be another problem -- often the header is too close to the door. This is a common framing problem -- the only solution is shaving off the header a tiny bit. If it was done correctly -- you can just screw up the door's frame
