Something Failed, let’s find it! Transmission Analysis.

I still wonder if all this starts with a slightly wrapped/bent fork? As soon as mine started jumping out of second gear I had it confirmed then torn open. The teeth on the dog ring were perfect, the fork didn’t looked deformed but had some light scarring. Still sent the gear pack to Robinson’s but replaced the forks for good measure too.

Forks look fine, no wear. Bike didn't break but you know ( in there, why not, might as well ) syndrome. Hopefully stop something before it happens. Don't want to have to open her again.

Dealer reported my forks were bent as well, but, when I rebuilt it myself later I reused the forks and have no issue. The "bent fork" I believe is Triumph code for "assembled wrong at Hinkley".

Yes indeed.

If I knew how to give a smiley/laughing face I would have done that.

Have my bike all apart, starting to reassemble. Starting to assemble transmission, did second gear upgrade, detent spring, bearings and bushings, washers, shims etc.. After reading many posts about some of the bearings installed backwards, I'm concerned. One bearing is metal shielded on output shaft, I figured the shield goes toward front of case. The second brg. is plastic shielded on rear of input shaft, and figured the shield goes toward frt. of engine. There is an oil hole in rear bearing that feeds rear input brg. and brg for torsion shaft. Bike is an 05 silver rocket. Can someone tell me correct direction for those bearings. Thanks Gerald

Calling @Rocket Scientist @warp9.9 - these guys should be able to help

Below is a properly installed bearing on the front of the torsional damper shaft. The seal should face the rear because it gets oil from the transmission. Commonly they were installed arse backwards at the factory. The rear bearing (old style) has only one seal; it is towards the rear also (so oil doesn't leave the engine thru the drive shaft galley). The new replacement rear bearing is double sealed and packed with grease -- because the Triumph engineers thought oil would migrate back there by osmosis. Very stupid. So they changed to a sealed unit with grease. I suggest you do the same while its open.

Told you so...!!! So much knowledge on this forum!
