I've been looking to "update" my 2006 Dyna Low-rider with a chrome inner primary case instead of the standard black case. My problem is, Harley list three different part #'s : 60794-06 or 60794-06A or 60794-06B. I know this certain year Dyna Low (2006) has/had problems with the IPB (inner primary bearing - replace @15K miles per Harley - that has now been rescinded by Harley) due to bad case fit/machining of the original cases (and possibly the transmission case too?). I was wondering if the 60794-06B case (corrected alignment/updated bearing perhaps?) is the correct case for my 2006 Dyna or do I need to order the original 60794-06 case to avoid any more headaches? As you may I guessed, I'm also changing out the crappy 2 piece rotor/stator BEFORE it disintegrates with the new welded one (40356-06B). Oh yeah, I'm also installing a new front motor mount (47583-90B), the updated chain adjuster (39929-06A) and the steering stem washer (45727-08). Thanks in advance for any info given. Note : All new inner primary cases come with new bearings and oil seals already installed (per Harley - and no, I haven't called my local HD stealership for an answer - I trust you guys for the right info !).
