diesel Posted November 29, 2011 Share Posted November 29, 2011 A while back, I bought a used Jake brake setup off of a salvage yard engine. I started in on the project yesterday only to find that I did not get the Jacobs exhaust valve yokes. The Mack part number is 891GC46AM (Jacobs part #017710), which I need 6 of. I went back to the salvage yard and found 5 of them off of a 427 E7, but do not think they are the correct ones. Does anyone know where I can find a set of these without paying $100 each from Mack? Thanks. Quote Link to comment https://www.bigmacktrucks.com/topic/21844-need-help-finding-part-for-jacobs-brake-on-e7/ Share on other sites More sharing options...
