Lower Timing Chain Blew-up!!!!!!!

[busajack]

Well Jack, we've got the answer. I still think that it's a possibility to remove the sprocket through the hole. without taking the cover off using a pair of hemostats to slide the sprocket off (so long as you can get enough slack in the chain). It would be good to try than avenue and then if you can't, take the cover off entirely. Doing it that way, you don't have to disturb the valve timing at all. I believe I'd align the static timing marks and then pull the sprocket. That explains the 27Nm torque value too. The big hex nut isn't torque'd at all. It's just a means of holding the crank while you tighten the the SHCS

If it indeed will come through the hole it would be a time saver and a cheap (relative) fix.

What we really need to know is at what VIN number at at what point in time, year and month, did Triumph change the design and implement the new sprocket/key in production models?

We are assuming sometime in '06 but exactly when in '06 and what unit number. That's the question.

Right on Flip and hope they didn't change the crank snout so that new parts need a new crank..If the dealers can't answer that,then mabey I'll just drive spike through there front window. Do ya think Hinkley would hear about It..HaHa Crazy Jack

That would be engine no. 228389 then 228390 for the first of the redesigned gears.

More questions...

Obviously for you to come up with the engine numbers where the change occured makes me think that you might also know what exactly changed. Was the sprocket (it's not a gear, it's a sprocket) redesigned as to it's physical appearance or was the fit of the key changed?

Please advise.

Since we had two good threads going on this subject, av8r4fun's "Timing Chain Blew Up" and Jack's "Help Me, I am Blind and Drunk and Can't Read" thread, and each had some good info, on Flip's suggestion, I have merged them. A redirect for Jack's thread will be in place for one day. Hopefully the authors of the original threads won't mind.

Am I good or bad?

I do have a nagging question and that is. Is the engine number the last 6 digits of the serial number or is it stamped somewhere else other than the right hand sie of the engine near the footpeg? If that's the engine number, I'm good to go at 258452

Good call Pig9r!!! I agree, it should be together since it is related...

No addt'l info from the dealer as of today. Probably will have something later on in the week.
