Posted : 02 Apr 2011 - 02:16   Post title : Oil leak
 
Just been out doing some 2-up shakedown miles on the T/Bird now we have a decent seat, and I note a small oil leak from the front of the motor, centre, base of the barrels from the plate retained by 2 8mm bolts, which I presume (haven't yet got a manual or tech info together) is a cam chain tensioner. I've searched a couple of fora for this problem and see it mentioned in conjunction with a few other leaks etc, but haven't been able to find many specific remarks on it. I'm reluctant to start dismantling things in ignorance of course - be a bummer if something went 'sproing'!! Of course, I can take it to the dealer, as the bike still has 6 months warranty, but don't want the beast to disappear into the system while Triumph NZ gets its act together. The riding gets a bit murky here late in May, and I want to get a good few miles up while I can, and so that any common glitches show up before the warranty expires. Having said all that, a tiny oil leak doesn't bother me much (I owned a Trident in the70s...!) Just be interested to hear if anyone has tried fixing this themselves? And also if anything wll go 'sproingg' if I undo the plate? I already gave it a little tweak, but after 250km yesterday, the weep is still there. Thanks - Pat

There's two o'rings behind that plate on the tensioner itself.I suspect that's where the problem is.The o'rings are only a buck each.I just went on to Bike Bandit's web site and looked at their exploded view of that tensioner.But I would wait til I got my SM before goin after those o'rings so I'd have somethin to refer to if I got into trouble.You can go thru warantee or do it yourslef if ya have enough confidence.Dave!!!

try bikebandit as dave mentioned for exploded views
Link

miight help

alternative, get your dealer to photo/register the leak with triumph, dont leave the bike till the parts arrive.
then spend the day they are fixing it testing a rocket or storm lol
why should you pay out for the fix?

as to the trident
met a bloke on saturday up on the pennines at a great place called hartside cafe, bought his triumph trident new 36 years ago and it was looking excellent with 210,000 miles on the clock. am kicking myself now for not taking a pic.

Gotta torque wrench? I can look up the TQs for you.

I had that and I just cinched it up the missing 10% to spec. But, you also, may need the O-rings. That's gotta be a mess to change.

Ah, Bike Bandit, that's what I needed to know, good site, thanks Dave and Zolti! I've used the World of Triumph parts locator before, but that doesn't seem to include the Thunderbird. Yeah, the 2 O-rings will be the problem i guess - can't nip it up more, but the torque figure would be useful, thanks Dizze (12nm or so I imagine?). Like you say, might just mention it to the dealer service guy and see what develops, the weep is pretty negligible anyway.
Yeah, there's a large number of Tridents around in NZ still, some real long term diehard owners; in fact the guy I finally sold mine to in 1984 still owns and runs it. Hard bike to keep on the road for everyday running though, but Hyde parts improve things a bit. Cheers for the info and links - Pat

+1 - there have been a few of these that have leaked and simply needed to be tightened.

Dr Pat get the bike to your dealer and get the oil leak documented under warranty. My first T.Bird ahd the same problem and my dealer installed two sets of O rings and it still leaked. My daeler told me that Triumph was going to redesign the O rings at some point. It is quite a job to replace them as they have to go into the lower right side of the motor, about a 4 - 5 hour job.

thanks lwc, that's good to know! I've mentioned it to the service manager at the dealer and he said not to tamper with it myself, but they'd look into it with Tr.NZ and address it when I brought it in (which will probably be when I get a 10000km service, as I want to get a few miles up in the last of autumn, unless the leak gets dire). I wonder if abortive attempts to fix yours were because a tech didn't realise the 2 O-rings are differnt sizes, and put them in wrong way round or something? Can only speculate; anyway, I'll post any info I get up when it happens. Chances are Triumph sorted this little problem on later bikes, and it is only an early teething trouble for the model - cheers, P.

I suspect that when the o'rings were installed at the factory,they were installed dry which is a big NO,NO.Shame on them.So naturally,when the chain tensioner was installed,and because the o'rings were dry,it would not just slide thru the o'ring[s] as it should without causing damage to the o'ring,and creating a leak.Whenever any o'ring on any application is installed,it has to have some form of lubricant applied on it.I learned that the hard way 40 years ago because I didn't think.And it was a *uck up on my part that I have never made again.

Mine were replaced at about 1000 miles on my July 7 2009 delivered 2010 Bird (one of first 200 built). Dealer said they were given 1.5 hours to replace the o-ring seal. One of many that had leaks at this location. No problem there since.

 
If there's a T-bird in the garage then your either sick, broke or missing the time of your life.
Get out and ride that Bird.

The Tbird arrived June 26, 2009 - Speedy was traded in June for a 2012 Bonnie T100.
