I have a 2007 yamaha kodiak 350 atuo .the timing chain wore out i replaced the chain and gears. i romoved the gear on the crank shaft that aligns with the counter shaft balancer. When i got it all back to gether it vibrates untill u get past half throttel. Im wondering if the piston should be a tdc or bdc when i ut the gear bake on the crank and when i align the makes on it to the counter balancer ???? thanks

SOURCE: gear shaft

If you are trying to change the boot over the U joint at the swing arm, you don't need to remove any shaft to do that. You do however have to remove the swing arm.

The balance shaft isnt likely to jump a tooth, unless someone has installed it incorrectly. And if this was the case there would be problems in all gears

Youve probably done this but check the chain and sprockets are in good condition, and adjusted correctly.

SOURCE: Hi, I

From memory I believe there are a couple of dots on the balance shaft drive gears, the dots line up together

The timeing markings should be on the flywheel, F = fire T = top dead centre, however with the piston at the uppermost point, this is known as tdc, and the camshaft should be fitted with the cam lobes facing downwards, thus the valves closed in this position, on e assembled, move engine slowly with spanner untill 1complete cycle with no obstructions, if the engine meets any obstructions stop and recheck timeing and correct, if ness
