ok wow, so I have found many things out that I have heard mentioned here, and Im curious what you guys think? Obviously the "male" end of the dogs that go in the holes on 5th gear are "tapered" this is to ensure it stays in gear when "Load: is aliped to the gears...n now what I spent this evening doin is taking lots and lots of different measurements from both the factory 5th gear and the mikes xs 5th overdrive gear, the width of the mikes gear is slightly larger I could fit a .012 feeler gauge between the factory gear and the washer under the snap ring... and a .006 with the new mikes xs gear, not a problem there, kinda good IMHO.... then the inner diameter of the hole in the center was slightly smaller than advertised, but slid on nicely and spins very smooth, the machining in there is good and clean... now on to what weve all been waiting for the "dog holes"....now before I continue, I was informed by a member on this forum that my posts are hard to read and hard to understand, I apologize for my horrible grammar, and my drawings here are even worse.... so bear with me, we will get there, or at least I will...
so the comment by GGGARY was to check the gear for undercutting? I didn't really know what he meant but I assume he meant to look and see if the "dog holes" where tapered inside ... to match the taper to the "male dogs" protruding from the gear next to 5th gear... and so i took some measurements as I said and couldnt find that taper in the holes, neither on the stock 5th or the mikes 5th overdrive gear... I did do what I would call a common sense test ... i engaged 5th gear with the factory 5th in place and put a load on it with my hands and tried to make it "slip" or "jump" out of gear, and then changed out the gear for the mikes 5th and did the test with my hands again, and to the "feel" of it, the mikes xs is a better engaging "dog" than the factory gear,
here are my thoughts
1 if the hole is not tapered like the dog then under load it would only be the tip or edge of the dog applying pressure, ya know what im sayin???
2 them machining process to taper those holes does not look to have been done, yet I am capable and have the tooling to do so.
3 should i make them match, IE the taper of the dog and the inside of the hole?? or am I overthinking this, I have read some treads on 5th poping out of gear and it would be because of this reason,
here are some crappy scetches of the two exsamples, from what I can tell there in not taper in the hole of the factory gear, I have been wrong before, anyone chime in and let me know
