diamondred 63 #1 Posted July 17, 2014 I have recently purchased an eight speed transaxle from a "recycle center" , other than knowing that it has 1 1/8 " axles, is there any way to determine if it is a limited slip? ...Say 5060 or 5073? or do I have to open it up? Thanks. Share this post Link to post Share on other sites
stevasaurus 22,882 #2 Posted July 17, 2014 If the brake shaft comes through the case in the hole nearest the axle then it is a 6 speed with 1 1/8" axles and 10 pinion L/S differential. If it has a dip stick, it is a #5071. No dip stick, #5060. This assumes the trans is original, and has not been converted. If the brake shaft comes through the next hole toward the front of the trans (the cluster gear shaft)...it is an 8 speed. With out tearing the trans open...you can try to peak through one of the fender/seat bolt holes, or maybe the dip stick hole, and count the bolts holding the differential together. 5 bolts is the #5073, 10 pinion L/S. 4 bolts is an 8 pinion differential if it has 1 1/8" axles...#5091, 103907,103916 or 103918. An 8 speed with 1" axles is a 4 pinion #5086. Share this post Link to post Share on other sites
daveoman1966 3,762 #3 Posted July 17, 2014 (edited) Set the trans on a block with both axles off the ground...turn one axle. If the opposite axle turns in the SAME direction, then it is a 10-pinion LSD. If it turns in the OPPOSITE direction, it is either a 4-pinion or an 8-pinion differential.

stevasaurus 22,882 #5 Posted July 17, 2014 (edited) What Davoman said...only works if the trans you have is in good shape...and the differential is OK.. If you buy it off the ground at a show...what he said may not work...it is worth checking out, but no guarantee. Theoretically, if you turn the axles slow enough, the other one would turn in the opposite direction...turn it faster, the limited slip will kick in...again...the transmission needs to be in good working order for his to happen.

Racinbob 11,238 #6 Posted July 18, 2014 OK, what Daveoman said was what I've heard. It makes good sense what you are saying Steve. My Dad's Raider had the 10 pinion LS and I know it works well. So........with that being said I now have to find out something. What the heck happens inside the differential to make the limited slip kick in? Share this post Link to post Share on other sites
stevasaurus 22,882 #7 Posted July 18, 2014 Nothing actually "kicks" in, but if the spring is weak or cracked...the differential will act like a regular differential. The spring has to be good for the L/S to work. If the spring is good, both wheels will turn in the same direction. In other words, you could be buying a bad 10 pinion and think you have a good 8 pinion...thus...count the bolts in the differential. Share this post Link to post Share on other sites
