Hello,

Firstly, what a great forum and what a pleasure it is to be able to talk to so many enthusiasts.

My bike is a 1984 Tenere XT600, bought because I am tall, love classics and thumpers and dream of travelling. I bought it knowing that it needed some work and was ready to get greasy (I have rebuilt a 1960 Triumph and a 1972 Commando) and was also prepared for some 'sophisticated' Japanese engineering.

The wheel bearings needed replacing, I did that, it needed a new chain and spockets so I did that. Great, I thought. But then oil started to blow out of the head gasket (RHS). I read up on replacing the headgasket in my Clymer manual, dropped the engine and took the head off. I then decided to replace the main shaft as the final drive splines were very worn (one turned up on ebay, lucky). That went ok. But I have noticed some slight play in the main crank bearings and as the engine is out and in bits I might as well have a go at replacing them.

My questions are (and prepare yourselves, they might not be the last)...

1/ How do I remove the cam chain sprocket that is mounted on the crank shaft?

2/ Also How much radial play is acceptable in the gudgeon pin? I have a tiny bit of radial play but no movement up/down (if you see what I mean).

3/ Whare is the best place to get XT600 34L parts from in the UK. At the moment I am going to my Yamaha dealer and am always horrified at the cost!

I hope someone can help me here, I am having withdrawl symptoms and need to get back on my bike as soon as I can.

Thanks

Lewis

cam chain sprocket was part of the crankshaft on my wr400 ,,not removable at all .Real pain in the arse .It might be the same on the tenere . But it would have to very very worn to justify a new crank. Just put a rod kit and a new cam chain in it and it will be good to go forever. Old yamahas never die

forgot to mention, It may be cheaper to get your parts sent over from australia , postage is cheap out of australia, try teammoto yamaha in brisbane
cheers

Hmn... the cam chain sprocket prevents me from pulling the main bearing. I will try to use bearing pullers when I can borrow some. If it was on a Brit twin I would have hit it with a ruddy big hammer! Thanks

I will have a go at attaching a pic....

Hi there, I allso had to get the cam chain sprocket off. Took it to a engineering shop, the guy battled but got it off eventually. He used 5 tons of pressure ( not a typo) to get that gear off. Good Luck....Jaco

PS. just check on the gear is a "dot" make sure when you put the gear back it checks out on the crank
