bob2 posted:Yes- it will work on the E7. I doubt seriously that it would work on the SD7. The central drop-down gives you slightly more room, since the drive shafts can be longer. The original CLW tank drives were only on the very long SD40 series, and even then they were not great. The longer the wheelbase, the more the truck swivels.
Any of these systems require high quality U joints. Don’t get me started on early Overland.
Works fine on Sunsets SD7s. It is more visible in the single tank vs dual fuels tanks but was designed and tested for it's minimum rated radius.
