Parting out 613B Scraper

I've decided to part out my old 613B scraper instead of fixing it up to sell. I know Caterpillar buys parts for their reman program, but I'm not sure which specific parts they want or which ones bring the most money. Does anyone know if there's somewhere else that pays better than CAT for cores? Any help would be appreciated.

If you don't hear back from anyone here, I'd recommend reaching out to a Cat dealer directly. Cat probably has a specific division that handles used cores and parts for their rebuilding program.

Thanks.

Have you had any luck?
