1981-1985 Mercedes-Benz OM617 Turbo Sanden A/C compressor retrofit kit. Complete mounting kit for use with Sanden model 4709 (preferred), or 4272 compressors. The kit includes: mounting plate, front and rear brace, compressor "banana" brackets, adjustment bars, oil cooler line support bracket, premium Continental belt, fasteners and hardware to complete the installation *. Priority Mail shipping included to Continental U.S. Note: You will need to source a Sanden #4272 (132mm clutch), or #4709 (125mm clutch). The belt will work best with the #4709, but will be a little tight with the #4272. Source for a hose kit is available upon request.* One long bolt and oil cooler line clamp from R-4 hardware needs to be retained, and used for new compressor installation.
