I've recently run in to accelerator pedal issues on my VS similar to what apparently (from a search of this site) plenty of other folks have complained about as well: the little 'fin' on the back of my accelerator pedal was riding to the left of, and subsequently binding on, the OEM cheap plastic roller behind it resulting in a very stiff and difficult accelerator operation.
I'd like to offer an easy solution that I am considering to be temporary (I am going to replace my pedal cluster this winter), but I think could be used longer term.
After doing a little sniffing around on this site I decided that as a temporary fix I would simply try to 're-align' the accelerator pedal by adjusting (read: bending) the fin on the back of the pedal. Within just a moment and with minimal effort, SNAP - instead of bending at all, the damn thing broke right off.
Well, SHEEEEE-iiitttt . . . . . . . . what now?? This is 'crap-tastic'!!
After extricating myself from the confines of the footwell I took a couple of deep breaths, exhaled a couple of my choice 'go to' expletives, and started to just root around in my collection of spare hardware. After some brief experimentation, I made an interesting discovery:
With the back of my newly modified accelerator pedal now flat, I pulled the e-clip that held on the cheap plastic roller, removed the roller from the small 'axel' pin on the cable assembly, and instead installed a small diameter roller blade wheel. The bearings of the wheel fit PERFECTLY on the axel pin (and I believe these bearings are all the same size, regardless of the diameter of the actual wheel, which can vary). I added a small fender washer to help with spacing and positioning of the wheel, and secured it with an e-clip.
My accelerator is now VERY smooth, easy, and comfortable to operate. The wheel behind the pedal is solid, secure, and basically hidden behind the pedal. The pedal is not constrained to any sort of a 'track', so if it moves left or right slightly it doesn't negatively effect the operation - the wheel just rides anywhere on the back of the pedal as it is depressed. Again, ultimately probably just a temporary fix, but one that works pretty damn well!!
