Pella door roller parts and installation instructions

A handy person from newport, ri says:
I have a 5' Pella sliding glass door that is used daily with the blinds between the glass that needs new rollers. I believe the door was installed between 1995 and 1998 - I think?? The door has just one hole on each side for roller height adjustment and it appears the roller assembly is 'pressed' in. The sides of the roller assembly have no flanges, just flat and recessed even with the bottom of the door. The assembly appears to be 3" long and the roller appears to be 1 1/2" long and 3/8" wide. The width of the assembly appears to be 9/16" wide. I have what I believe to be a part number from a Pella part catalog for a galvanized roller (0C5Y0000)but I'm not 100% sure its the correct one. I have pics of the roller as it resides in the door as well. I looked for a door serial number but all I can find is a reference to Guardian tempered glass on the bottom right of each pane. Lastly I'm curious how to remove and install the roller assembly as well. Any suggestions? Thanks in advance. Patrick

I think in this case, the only way to know for sure what roller you have is to remove it from the door. The code you gave is usually related to the 81-244, but you mention that yours does not have those flanges, so we shouldn't go by that. You could instead consider our 81-098, which is a genuine Pella roller, or our 81-249, which is generic.

Hi Paul,

Thanks for you quick response. I should have mentioned that I have the aluminum clad outside/wood inside slider but maybe that makes no difference. There is definitely no flange on the roller assembly and looks pressed in. So question, are they just pressed into a cavity and fit snugly - no visible screws keeping them in there??? If pressed in, is removal just prying and wiggling it out to get them out? If you think your generic is the correct size, I'll be happy to try it! Please let me know. Thanks much.

Service people tell us that the rollers are just pressed into the bottom rail of the door. I imagine the weight of the door keeps the roller in place. To remove the old wheel, try to pry out with a screw driver. As for adjustment, you should have a hole on the side of the door where you can use a screw driver to adjust the roller wheel up or down.

We have sold both the genuine and generic rollers for Pella without any problems. The only difference between the rollers is that the wheel in the 81-249 goes 1/16" more past the housing than the 81-098. You might have a problem if your glass doors are tight in the opening height in clearing the bottom track.
