TDSU or output shaft bearing problems

[seeya]

Leigh, what kind of noise/vibration were you having to decide it was the OSB? My bike has a howling type noise and a vibration on decel @ low rpms. Feels like you can actually feel a bearing grinding

Hi. I didnt feel any particular vibration or hear any particular noise. The first indication was metal particals in the oil when I did a service. The bike is a 2006 black engined model with 3000 miles on it. Triumph, of course, wouldnt do a thing. I purchased the update kit and with the help of friends, stripped the bike down and removed the TDSU. The bearing was in the process of wearing down and would have soon broken up. There was a large amount of slop (play) in the bearing, so it was replaced as was the engine casing for the tdsu. After the bike was bolted back up, I flushed the engine, changed the filter, new filter on and new oil. I will flush the engine again after 500 miles to see whats what.

I had the vibration with mine it was pretty well chewed up they must have put the bearing in backwards in yours to does not make sense how they could run that many with out some quality control catching the mistake. My rocket is a 07 does anybody know how many years they had this screwup was looking at a used bike for my wife would like to avoid the bearing problem

Forgot to mention - the bearing HAD been put in the wrong way.

This is a link to what I found in the oil catch in the sump





This is

here is a link to the picture of the OLD bearing



and here is a link to the NEW bearing



Incidentally, the splins at the end of the shaft (engine end) were dry as death valley. I used a ton of moly grease on the splines when refitting. I reckon checking of the splines should be an annual/2yr service check.

Wow ! what is a mess, good illustration. My bike developed a howling type noise in any gear on decel below 2000 rpm, also has a vibration with the noise. It just started one day and I've been trying to find out where it's coming from, it's on the left side, from the center of the engine to the rear shock. I've checked everything to make sure nothing was loose that could be making the noise including bearclaw, floorboards etc. I've been on here asking other Captains about their experience with the TDSU/Output shaft bearing and what i'm experiencing seem to be different from thiers

My rocket vibrated like the side of the motor was coming apart the same bearing was put in backwards with oil deflector plate the wrong way, I had a little over 15,000 miles at the time. Make sure to check the in play in your rear differential it seems if you run it too long it makes the bearing and rear differential go bad it did mine and from what I understand when the factory fixes them it is a requirement to do the differential to, just thought I would give you a heads up you might luck out and it be okay.

Thanks Uncle Jesse, I'll Keep that in mind when i tear it apart

TDSU bearing problems

Just did mine. It's still a major job but you basically have to unbolt and disconnect most things including the ht leads and pivot the frame on the front frame mounts. You also have to to loosen but not empty/remove the radiator.

Hi Leigh,
How many hours to tear down, i want to buy parts first and save time or do you think I should wait and see whats inside. Do you have any photos of bike during tear down.
Thanks Mate
Andy

It basically took a whole long day for the 3 of us to tear the bike down, extract the TDSU, find a garage/shop to do the bearing pressing, and reassemble. This was the first time any of us had tore down a bike to this extent, so an experienced person might be able to do it quicker.

What was left over to do the next day was the engine flush, oil change and try and work out how to tighten/torque up the Castle nuts without a Castle Socket (Triumph wanted £70GBP for 2 castle sockets - I didnt buy them).

I have a set of photos and some video of us (the 3 stooges) dismantling the bike and the TDSU.

Here are some snippets from my write up from another forum...

Update: 31/8/11 - SYDs arrived at 8.30am to work on my bike. Time now is gone 10:30pm and the bikes is 95% sorted and rebuilt. Buggered because Triumph in their infinite wisdom decided to use Castle Nuts (a 31mm and 38mm) and of course I dont have those. So, as soon as I get those I can torque down the 2 bolts holding the frame and swingarm on and then the bike is finished. I got a **** load of photos and videos of the process and will post afterwards.

ps. Triumph installed the bearing in the wrong way on my TDSU and although the bearing/cage hadnt broken up, there was some serious slop in the bearing movement.

pps. Didnt take the frame off the bike - pivotted the frame on the front engine mounts to gain access to the TDSU panel.

Update 1/9/11:

Check out the slop...

This is the video to prove Triumph are a bunch are twats...

In order to complete the rebuild, I need to torque down the frame to the engine and the swinging arm. Both need castle nuts - 31mm and 38mm - these parts (from the manual):



Anybody any ideas where I can get these or similar today?

Triumph want £65 for the two sockets going to see about cutting down a 31mm and 38mm normal socket with the a grinder.

Quiz time... Which one do you think Triumph fitted?
