cfd511 Posted March 4, 2019 Share Posted March 4, 2019 I have a 2001 Mack 688 with the 400 and 18 speed mack tranny. The truck was an old county plow but still in great shape . i painted the frame ect. My issue is I'm trying to make the truck nice but these trucks had the hydraulic pump running off the front of the truck which makes the number stick out. This pump is a two stage which i don't need anymore because it only is needed for the dump bed and once and awhile a plow. so my question is how do i get the pump running on a pro system which is connected to the tranny. anyone know part numbers and what i would exactly need. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
