Well I found the noise of the rock crusher noise coming from the tranny. After rebuilding it with the hanlon kit and replacing the 1-2 slider, 2nd gear and the 3-4th shift fork and driving it for 10 miles a pretty bad noise suddenly let loose. I finally got it out and opened up the top cover. Everything looked perfect so I bolted up the tailhousing to take a look at the gears and spin the input shaft. The sound was there when I put a little side to side pressure and noticed that the input shaft had a little wobble which wasnt there before. Pulled off the front and the roller bearings were all eaten up and flat spotted. The mainshaft is a little burnt too. My friend and I are kind of at a loss as to why my bearings failed. Only thing that we could come up with is if they were the wrong size or not enough lube. I put 2.75 quarts of Redline D4... maybe should have put 3. hehe. Oh well it looks like a loss because its probably not worth replacing the mainshaft. Any suggestions or should I start planning for a TKO 600 or possibly a Gforce. Both price out to be about the same. I'm not conserned with the weight difference. Just want a better tranny... not so much an upgrade so I'm leaning towards the TKO600.

I just saw how a non cobra mainshaft can be modified to take the cobra caged roller bearings! That might be the ticket for now instead of coughing up the 2000 dollars for a new setup. At the very least it will give me time to save up. Anybody have any experience with this?
Hanlon offers it i think. Here's a link with a pic.

Well my friend's dad which is a machineist by trade came by to take a look at the damage and he said that the roller bearings were really soft. He tested it by running a file on the bearing and it bit in. We found some of the original bearings floating around the shop floor and the same file just glided off. He then checked the caged roller bearings on the input shaft and said that they were a tad soft too. Apparently the original bearings were harder.... I'm going to call Hanlon tomorrow and see whats going on. They migh have gotten a bad batch of bearings...
