Hi,

Further to my recent post I have established the alternator on my r1200s is well and truly seized.

It looks a bit of a pig to get at and I can't even work out how to get the belt off.

I can't get a socket on the pulley nut as the front shock is in the way. It appears I need a deep 22mm ring spanner to get at it.

Is there anyway to slacken the belt or do I just need to remove the pulley or alternator to get it off?

It looks like I have to remove the tank to lift it out am I right?

Any help appreciated,

Jon

Hi Jon.

Sounds like now might be time to get the bike recovered to a dealer or to a good independent if you have one locally.

Yes you need to take the tank off, not difficult at all, there is no adjustment for the alternator so you just have to either cut the belt off and replace it with a new one, they're not expensive and it may well be due soon anyway, The Alty itself is bolted on from the top which is self evident once the tank is off IIRC, had to do this when my belt snapped due to the seal leaking a couple of years back. You have to wind the replacement belt on which was difficult without the special tool.

If the belt is still usable as an emergency spare, I think I would leave it on and just unbolt the alternator, then remove the old belt.
Install in reverse by installing new belt then tightening down the new alternator.
I'm not sure if it is possible to do it this way, but if it is you might save yourself some headaches.

Cheers

is it running now then

Hi,

The alternator is seized solid so I need to take it of and fix it/get it fixed pretty sure that is what caused all the problems and it will run ok once that is sorted, watch this space!

just slip the belt off , it will run without it

Hi All,

Latest update, the alternator is a b*****d to remove!

I've taken the tank off, unbolted the alternator from the top of the engine and removed the belt and the back of the alternator cover.

The frame tubes above the alternator prevent it lifting out from the top.

I can either remove the fuel pump and back it our or the front shock. Front shock looks like the easiest option.

Quick question: will the suspension collapse if I unbolt the shock, will the bike be supported by the forks alone or should I jack the bike up so the front wheel is clear of the ground?

Cheers,

Jon

Hi Jon, you must support the engine when you remove the front shock or the whole thing will collapse in a heap, I would use a scissor or bottle jack and raise the wheel off the ground.
