mnelles 1 #1 Posted 6 hours ago I got a Sunstrand 90 out of a Charger 12 (I think) from someone that came disassembled in a box. I have a basic idea of how to put it together but I'm not 100% sure on axle lengths (seems like one is slightly shorter) and a couple other small things. Any good manuals or videos? 1 Share this post Link to post Share on other sites

WHX?? 56,360 #3 Posted 5 hours ago I guess my question is why was it disassembled? internal issues? Might want to post some pics of the wear parts and see if the boys can spot some issues. Shouldn't be too hard to figure out which axle goes in which case by how the differential sits in the cases. 3 Share this post Link to post Share on other sites
mnelles 1 #4 Posted 3 hours ago Story I got was it needed axle seals. I put seals in it and started reassembly but it was torn apart way further than needed. Axles seem to be about a 1/4" ish different. I'm guessing it got taken apart and they forgot how it went back together. I acquired it from someone that got it in a pile of stuff from an auction. I haven't taken one apart ever but I thought I'd try to rebuild/reassemble it for the practice and education. Share this post Link to post Share on other sites
