replacement of rollers on slider windows

We need to replace rollers on 5 slider windows that measure 3 x 5-1/2 ft. high. Do you recommend the Heavy Duty roller (10-118) or the 87-006A (which is what we appear to have now)?

Also, any installation hints would be appreciated. The windows enclose a 2 story sunspace so access to the glass is really only available on one side.

Thank you.

If the sashes are that large (36"X66") then I would use 10-118 Heavy Duty BB Roller. To remove the old wheel, I like to use a large slot screwdriver and, with a hammer, tap out the old wheel from the side. To install the new wheel, place the roller on the top of the channel at the old location and gently tap the wheel down into the channel.
