    Well 50k on and nothing lasts forever it seems. When coming through commission track on the two day ride I found the bike hanging in gear sometimes, not every gear shift sometimes 10 mins between baulked shifts. When I got home I pulled the oil filter and it was good so I spoke with Nick at Tekniks and we decided to check the net. Seems as though a few Teneres world wide had failed a small bearing on the rocking selector arm. Symptoms are the same parts ordered and away we go

    The little arm with the little bearing in question

    As it has done 50k and 850+ hrs I figured a new piston would be in order, water pump rebuild kit and a timing chain

    Drain the oil have a beer and pull the clutch cover as I reckon we can do it in frame. Pulled the clutch plates and hub have a beer. Then I find this shit in the bottom of the cases and start having multiple beers

    Nick knocking it apart

    Big shout out to Nick here at Tekniks he is staying back to get apart so I can get parts ordered tomorrow. People may not realise Nick does a lot more than suspension. He has done all head work for all the bikes I have done Fish’s DR, Nickj’s CRF to name a few.
    Will post up the pictures when it’s apart. I was a bit disappointed at first but considering where it been and what it’s done it’s ok at this stage

    Yeah I am happy with it Rocket, turns out the little bearing we thought had failed has, but the follow on getting home was the single broken gear, more in the post

    Yes and no James, I ride it for all I can all the time. If I had known about the bearing in the picture I would have replaced it, Nick can do it in the bike it turns out. $35 and happy days, mine split the bearing causing it to not select correctly and result a broke gear :(

    If you look closely you cab see the split in the bearing outer

    So its stripped, broken 3rd gear

    IMG_1467.jpg

    The bearing we thought failed had indeed failed, see the split out case

    IMG_1465.jpg

    Sits on the gear stick input shaft

    IMG_1464.jpg

    Good news is Nick can do in the the bike if you get it before failure, if you have a tenere ring Nick at 30k and book it in, cost less than 3 cartons of beer ;)

    Cases being split

    Piston looked incredibility good for 50k

    IMG_1456.jpg

    Bore still has cross hatch

    IMG_1457.jpg

    Piston is a forged item and measured up with no wear :ohmy: Some slight wear in the top ring land but thats to be inspected

    IMG_1458.jpg

    IMG_1461.jpg

    Heads in great condition, looks good a side benifet or fuel injection

    IMG_1455.jpg

    Other than the broken dog on 3rd gear the box and the rest of the engine is in like new condition I am amazed :blink:

    3rd gear, missing half the dog teeth

    IMG_1470.jpg

    As you can see there is no wear on the remaining dog teeth

    Hope Yamaha have the gears in stock. Wishful thinking perhaps. May as well throw a timing chain at it while we are there. Ill have a goof look at the rear of the bearings tomorrow after its all washed up.
    I’ll strip the head too, give the seats a cut. Might port the head if I’m bored!

    Thats a relief TB,sounds like prevention better than cure. ;)

    I have an awful lot to learn and seeing your bike in a million pieces meant panic stations

    to me. :ohmy: :blink: :laugh: :laugh:

    I will be booking my Tenere in with Nick in the new year, I’m just about to drop the oil out for the second time since I have had her.
    30k on her now so it can’t hurt to get Nick to have a look.

    I’ll do more than look, a few gaskets and the shift drum sector bearing is what you will have replaced. No sense in breaking gearboxes when it’s preventable.

    :whistle:
    PREVENTION always better than a cure they say ;)

    Great review for the Tenere durability though TB :)
    You are not exactly kind to the machine when on the trails, and one could safely say it has done some hard miles the past 2 years

    Last night TB was a bit panicked that there were wayyy too many parts coming out of the engine and i would not be able to put it back together. Wonder how many cat and Cummins powered truck drivers have said that to TB? Hmmm.
    Anyway, all packed up now waiting for early Jan for some parts to arrive

    We have a turbo wash that is great for cleaning engines, the cases were it in for a half hour, there is little trace of red dust left.
