Pullstart 62,784 #1 Posted April 10, 2020 Are there any Dino videos or the like showing what moves and locks the two axles? It sure would be awesome to see how they do what they do! 2 Share this post Link to post Share on other sites
ebinmaine 67,266 #2 Posted April 10, 2020 There is one there. But basically, you have a ring of five gears that rides with one axle and a ring of five gears that rides with the other axle. There is a round piece of spring steel that contacts all 10 gears. It puts pressure on them and holds them from being a true open differential. 2 2 1 Share this post Link to post Share on other sites

Pullstart 62,784 #4 Posted April 10, 2020 Found Dino’s 10 pinion assembly video in his 5060 rebuild instructional thread. @stevasaurus I still don’t quite understand how it allows slip, it looks like all 10 pinions are in contact, all the time. What slips to allow differential movements? 1 Share this post Link to post Share on other sites

There's only a certain amount of available tension. Once the "pull" or "twist" of one axle exceeds that available tension it'll act like a VERY tight open differential by letting the spring move on 5 of the gears. That's why it's called "limited slip" not locking. Share this post Link to post Share on other sites
pfrederi 17,663 #6 Posted April 10, 2020 (edited) I have to question Stevasaurus video. i had never watched it,. He put the nuts on the short side of eh differential. That is not correct. The nuts go on the long side of the differential per the manual. When it stops snow I will go out the shop i have a couple short videos of 10 pinion when were seeing if the springs someone had made would work. The final product from Lowell does work.

This is true and the reason they do is because you don't want the nuts to hit the mushroom gear. We checked it both ways and determined that there is enough clearance if they go in backwards. Dino says he did a few bass ackwards and nobody's come back to strangle him! 3 Share this post Link to post Share on other sites
stevasaurus 22,706 #8 Posted April 10, 2020 Fred is correct...the bolts are in backwards in the video. This was pointed out to me very early, but the transmission was already gone so to do another video was not an option. I have also told many members that the video is incorrect according to the manual. Like Jim says...there is enough room to put them in backwards without having a problem. The thing is, in all the transmissions before the 10 pinion...what I did would be correct.(to have the nuts facing the brake shaft side. I wish I could go back in the video and say what is right. BTW, looking at those pictures in the thread, those bolts were that way when I opened it. I just put them back the way I found them. So sorry for missing that in the manual. As far as trying to picture what is going on in that differential...picture this...the limited slip does not work when not going in a straight line. That is when that spring just holds those floating pinions in place and a regular differential is in effect. When you are going in a straight line, the internals of the differential aren't moving, they are just going around with the mushroom gear turning the bull gear. Then the spring puts pressure on all the pinions so if one side starts to slip..the pressure of the spring will keep the floating pinions tight and turning. This type of transmission is based on going in a straight to make it do the Limited Slip. You can kind of visualize this in the 1st few seconds of the video when I turn the axle with all the pinions in place without the spring. With the spring in, I could hardly turn the axle by hand. Hope that helps. I went back in that thread and made a correction about these bolts just before that video. That should catch those that use the thread to re-build that transmission. 4 1 Share this post Link to post Share on other sites
