I recently picked up an '00 426, seized up. I got it pretty cheap, that is why I bought it. I already picked up a '02 crank with necessary gears to switch it over, expecting that is the problem. I was just wondering what special tools I will need for this job? I know the shop manual has all kinds of special yami tools, but which do I actually need? I have all of the common tools, and a couple of torque wrenches (smallest is 0-75 ft/lbs). This is the fist yamaha and fist 4-stroke (besides my pit bike) I will be splitting the cases, so just looking for some advice from experience. BTW, I can still turn the engine over with the kicker, but it turns really hard. The guy I picked it up from said it started seizing and he shut it right down. Any comments on the problem or teardown would be great!
