Diff orientation in FLM Hybrid Bulks
 

I know I read a thread on the internet a long time back about which way the diffs have to install when putting them in the hybrid bulkheads. I'm using the OFNA Hyper 7 diffs. Is there anyone who knows how they should be orientated when installed as I'm not doing a swap over but a rather from scratch build??


I've also figured out that since I'm planning on using CVD'd that the hyper 7 diff is a direct drop in. I know I'll have to shim the bulks where the diff mounts in the hybrid bulkhead bulk the shimming will only be 1 to 2 .2mm shims on each side so that's going to save me some time from putting the FLM axle shafts in that come with the FLM EMaxx 3905 spec chassis.

Once I get the orientation of the diffs figured out and 2 bearings for the rear pinion shaft bought and installed then I can get the truck build finished and some pics of it up even though it'll be nothing fabulous. I've thought about doing either a video or picture book to show the way to build it from the ground up. Diffs, towers, esc, motor, all parts, etc, etc, etc......

Diff orientation
 

The diffs can be installed either way inside the diff housings, and the only issue will be that you install the front and rear facing opposite from each other. They just have to be flip flopped because one faces rear and the other faces forward. If for instance both are installed with the ring gear on the same side they will oppose each other in rotation, which will bind up your drivetrain. From a mechanical standpoint whether the front faces left or right really does not matter as long as the front and rear are not facing the same direction. I hope that is clear enough for you and that this helps. Good luck and have fun with your setup.

Like Jerry said, it doesn't really matter so long as the ring gear is on the opposite side front vs rear; if the wheels spin backwards once you have the esc & motor installed and apply the throttle, you can just swap 2 of the motor wires around to reverse the direction the motor spins.
