Replacement roller for Marvin ultimate sliding door

I need to replace two roller sets for my Marvin clad ultimate sliding door as they rusted in a flood.

The model number on the door is NFR 269/270 and the catalog number was CN 5070.

For the Marvin sliding french door that I needed to fix, the 81-182 model worked perfectly.

The door is again rolling smoothly (maybe even better than when it was new).

This fit my Marvin door. (Marvin Ultimate and Ultimate wood trimline patio door - discontinued in 2003)

The part number from Marvin is 10820003 or 10820004. (I think one number is for standard metal and the other is for stainless steel)
1-½ inch wheels are key. (Most wheels are 1-¼" which ofcourse don't work.)

As for removing the sliding door - 5 Phillips screws to remove from top plate, a tug on the upper portion of the door and it popped out. The door is very heavy - it's a two person job.

My 25 year old patio door slides (silently!) like new. I hope others with my problem find your site.
