Balance Shaft adjusters seized?

Hi All

I have a 2003 st1300 that has a slight rattle from the engine while moving off or while accelerating under load. I assumed this may be the Balance shafts, as the bike has 60000 miles. I tried to follow the instruction posted on the forums here, but after loosening the pinch bolts the shaft does not move either clockwise or anti-clockwise even when considerable turning force is applied. I thought the adjuster itself was seized onto the shaft, but I removed the upper bolt on the adjuster and it rotates freely on the shaft.......both upper and lower adjusters are like this. I have read elsewhere on the site, there should be 90 degrees or so of adjustment.....mine won,t move at all. I tried adjustment with engine cold and warm, stopped and running.....is it possible for these shafts to seize ? Any help or remedy would be much appreciated, thanks in advance.

I did the same procedure on my '04 model earlier this summer and found the same thing, seized solid. I used penetrating oil and tapped with an impact screwdriver to loosen them up. In my case the adjustment made no difference. Good luck with yours.

Hi
Thanks for the reply.......funny I was thinking an impact driver might help, but was afraid I night break something. Just might give it a go !

The operative word is "tap".

Be advised that according to Honda these only need to be set upon initial engine build or reassembly. There is no service interval once set.
