Before I dump $80 on this tool I'll likely only use a few times in my lifetime, do I absolutely need this tool or can I make something for cheap that does the same thing? I don't want to mess with the crank balance, so if I have to get it, I have to get it.
I didn't use any special tools either when I closed my cases on my 87 KX250.
I used a barbecue to heat my cases to about 170 deg, and also froze the crank.
Once the case heated I quickly got the crank and dropped it in. I had to use a piece of 2x4 to tap the crank in because the coldness of the crank hitting the heated case will sometimes stop it from sliding in.
Then, I quickly applied yamabond to the case, got the other half of the case and installed it.....you have to work quickly, but it can be done. Just have everything ready and planned and make a dry run first.
With heat and freezing parts, you can put or removed just about every bearing in the motor without buying special tools.
