2nd Gear Blues

[Steel]

*Update*
New Bridgestone is on. Triumph has given the ok to open it up and see if it's a warranty covered item that is the cause.
The service writer assured me anything inside the bike will be covered.
It will be put up on the lift shortly.

Its kind of weird but I do not think its th edetent sprin pr you would have problems in more then one gear and i believe most of them were in th eupper gears not second. I suppose it could be your dogs on second are slightly rounded off pluss the sprocket spoke on the internal of the second gear cluster. where mine were probably more rounded which made it kick out of second gear at a lower rpm. I am just guessing though as I would open up the front to inspect the detent area on mine before I jerked the engine out. Either way since yours is in the two year warranty limit it should be covered. It sounds like you have a good dealer to work with so far.

You were right, it's not the detent spring. Now they will have to drop the motor and go inside to find the issue.
The service manager and the mechanic say it has to be a warranty item if it's in the tranny. He said once they determine it is a defect in part or assembly, then he will try to convince them to waive the cost of them changing my back tire.
They are closing for the weekend, so I won't know more until Tuesday.

Yep second gear dogs are probably starting to round off. could be from slamming her around , shims being wrong size (lord they probbaly buy them by the pound) or a shifting fork/drum movement which I would doubt except fork being ground or damaged . If it was the drum timing or not rotating enough to full move her into second I would think timing would be out on soem of the other gears. Some of this beyond the rounded dogs and improper shim thickness is just me speculating. The second gear clust and shims are what gets replaced in the update kit. I figure it a couple things one being tolerances although great for the machinist add up to one big screw up in the long run depending on which way they go. Tolerance is basically the total allowable deviation from exact part dimension, it is the difference between the maximum part dimension and the minimum or basically the ball field you have to work with. if dogs are short and shims are small not only will they not fit in the as far as they should but the shims can allow them to fit in even less. Same goes with the angle tolerance on th edogs and the female spokes they slide into. any advers angle can help them slide out causing rounding. This is why soem people spend th eextra cash to have them ground at a slight angle so the force holds them in.

When I investigated my clutch problems and a way to insure the proper back lash I measure everything to include the distance from the back side of the lifter piece to the fron side parting face of the motor case the thickness of th e gasket and the distance from the flat on the liftershaft to the front parting face of the clutch cover so I new where everything was before I put her together. It took a little time and effort but eliminated my lifter shaft breakage. I relaly believe the problem with the clutch aided my first second gear failure along with the shims on the second gear shaft bien to thin. One must alwys remember thes bikes are slammed together on a assembly line and when its running to slow short cuts are made to speed up the line soem of which turn out to be human error. Ie installing the rear output bearing in backwards so it could not get oil flow. Its either that or its because the brits drink warm beer for their liquid lunches

^^^ In gunsmithing we call this tolerance stacking.

All the parts can individually be within an acceptable range, but if you have parts that meet the small end of the range mating up with parts that are at the top end of their range; problems can occur.

They are still waiting on approval from Triumph to go deeper into the motor. The bike is just sitting there tying up their lift.
2 weeks and nothing. Is it always like this with Triumph? I'm not impressed with their service after the sale.

I hope they've given you a loaner in the mean time???

Hate to rain on anyone's parade, but hp and torque values are always equal at 5,250 rpm. The dyno chart in Scorp's attachment shows them equal at about 5,850 rpm. Something fishy there! Ask for corrected numbers and don't let them
B.S. you that these numbers are correct. (Good looking curve though.)

No they haven't given me a loner yet, but I've been out on a rig for the last 2 weeks. Just got home this morning.
They couldn't get approval on this side of the pond. The case went all the way up to Triumph in the UK. They finally approved for my dealer to open it up late yesterday evening.

 

[Steel]

It's open and they found the problem. Now they have to wait on approval from Triumph to fix it and send the parts. I'll be lucky to have it back by next weekend.

Next time I think I'll get a Harley. They seem to be more dependable and the customer service is much better.
