| Post subject: | Active Diff issues... |
The active diff is new to me, and this is the problem I am having. When I use the active diff, car seems to handle well, however after things get warm some binding occurs. It is much the same as if a bearing were going out, however I have checked all in the drive train, and even replaced them although they all looked and felt good. Things are binding up enough that my motor is over heating. I thought I had a tuning problem at first, however after feeling 'stumped' in that arena I found that the front end was binding up under the appropriate load. It is very inconsistent, however noticeable by simply 'dragging' the front end. I have checked the shims (using 1 shim to open mesh) and everything seems actually ideal (ever so slight play). When the car cools, seems as if no binding is present. I will have to check my notes, however I believe I am running Losi, 5k-5k-3k (front to back). I must admit, I am feeling a little disgruntled. With the difficulty of assembling this thing, (and immediately reassembling to replace bearings) and now the difficulties in running it, I feel that the $114 something that I spent was maybe wasted. Am I missing something? If so, please enlighten me. Thanks. |

With further inspection, I have noticed that there is a bout .100" movement (100 thousandths) in the front cvd forward/backward direction. This allows the gear mesh on the front diff to fluctuate from approx .050" to .100". Is this normal and acceptable? |

Maybe it just needs another shim. Mine needs two .2mm shims on the crown gear side to have good mesh, so a total of .4mm. With no shims it skips when braking. I got some 14x16mm shims so I don't have to open the diffs to shim them differently when I put them in my different cars. |
