Big thanks to aub1895 over on CF for lettings us save his writeup on an Eaton 10 speed swap
I did a write up 2 years ago on this swap, but now the photo's are no longer visible thanks to photobucket. I received a request for the photos and I couldn't go back and edit my post or get anyone from the forum to return my messages, so I'm reposting this write up.
So, I've blown up 3 of my stock transmissions and decided it was time for an upgrade. I have a P-pumped 24v with twins, and I haul heavy loads regularly, so I wanted to put a 10 speed in. I got the Road Ranger, oil cooler and driveshaft from a local junk yard. The transmission is rated for 1,400ft/lbs, so it should hold up to the abuse. I decided that I wanted to keep my stock bell housing and adapt it to my transmission, instead of using a SAE bellhousing, for several reasons. First, I have a southbend dual disk clutch that I really like. Second, I would have a lot more expense into buying a SAE flywheel housing adapter, flywheel and clutch. Third, a SAE bellhousing would take up more space and I would have to make a mechanical linkage for the clutch. I used a np205 divorced mount transfer case, and built my own mounts and driveshafts.
