For those of you who may have a unit like mine her is what I have learned. (2005 34' Georgie Boy Landau double slide unit)
1. The 10" bedroom rollers with 1/4" round shaft, part #VTR-10 are conveyor belt rollers made by Cass Hudson Co., 28117 Charlotte Ave., Elkhart, IN 46517, Phone 800-423-1511 & 574-970-2100, web site www.casshudson.com
then choose "Brackets & Rollers" from menu. Cost $7.00 each. Oh yes, one end of the 1/4" shaft is spring loaded - just push in this end to remove and replace the rollers.
2.Alexander Screw Products in Indianoplis did not make the rollers for my living room slideout but have rollers that could be used as replacements www.alexanderscrew.com
They actually provided the information to the Cass Hudson Company and they do have slide-out rollers that they have made for several makes of motorhomes.
3. AL-KO Kober Corp. purchased RBW Industries that made the slide-out system (#GSO-12024) on several models of Georgie Boy motorhomes. I purchased the replacement pins (#GR-1547 1/4" stanless steel clevis pin X 1 1/8") $2.19 ea. shipping was $16.55 for 6 of the small pins?!? You can get a PDF of the slide system with ability to purchase any replacement part needed.
Question - can I extend my bedroom slide about 1/2 way prior to jacking it up (from inside with a sissors jack) about an inch or so to replace the rollers? This would help me to get better access to the rollers and brackets. Just don't want to damage anything in the process.
