Another cam chain tensioner question

I have a 2004 750 Brutale and it recomends replacing the cam chain tensioner at 36000klms. What actually wears out in these, I have read all the posts on this web site and understand about the ones that were replaced under warranty. On the 750's it appears to me the only thing that would need replacing is the spring which could loose its tennsion from the engine heat, would it be possible to remove the large bolt in the middle of the tensioner and replace the spring, saving all the work removing the tank and rocker cover.

Graeme.

Donsy is 100% correct, do it right, your bike is ten years old, replace the part, trying to be cheap will cost you a great deal of money if it let's go.

Agreed. Do it right mate. It's worth the peace of mind.

What we've got here, is failure to communicate.

The one in my 2004 750 Brutale lasted 8.5 years and 97000km.... When the tensioner stops doing it's job properly you will hear a VERY different noise from the engine. After that the chain gradually eats the chain guides and then snaps. I'm pretty sure MV never tested the engines or anything else much past 36000km and that's why everything is listed to be replaced at that point.

I don't know if I'm putting you in trouble but as far I understand you keep a history log for your bikes, I would really like to see a post - if you haven't done it yet, with your experience from your Brutale after all those Kms.

thanks in advance

I don't really have a log, but I have almost all the receipts with costs and km on them. Is that the sort of info you are after or something else ?

I replaced the cam chain tensioner the other day, the bike has travelled 37000 klms as you can see from the pictures the only problem seems to be the little spring that operates the pawl on the extension arm, the internal tension spring seems to have the same tension as the new one, I have not moved the the arm since I pulled it out so you could assume the cam chain is still in good condition. While I had the rocker cover off I checked the valve clearance and that was all in the tolerance specified in the manual. The tank was off so I decided to replace the plastic fuel line fitting on the tank, with the metal ones, these were purchased from Trooper Lu's in Sydney. I would like to thank members on this site for there posts and information regarding these jobs undertaken.
