I called Cometic Gaskets and had them make me 2 "4mm" aluminum base spacers for an 86 LT250 because they didn't have 8mm thick stock at that time so they cut me 2 4mm ones. Then I used 3 base gaskets to make a sandwich. One on the top, middle, and bottom.
Sorry, but it's a little dirty and the sealer, but you'll get the idea.
Also, you will need longer base studs or, if they are long enough, you can back them out a bit. But I don't recommend that because when you torque the jug down, it may pull the studs out of the cases.
How do you split the crank to remove the rod?
Crank shaft jig And super strong press. This is not a job to try without the proper equipment.
Even if the crank is no good
How do I get spacer plates?
A crankshaft has to be true when put back together. If not it will tear apart. The guy said cometic gaskets. You will have to call them to order the plates.
Call Cometic Gaskets and tell them you need 2 "4mm" cylinder base plates cut in aluminum and 3 base gaskets.. It's that simple.
Crank shaft jig And super strong press. This is not a job to try without the proper equipment.
my father rebuilt my zilla crank wthout a jig. used a 50 ton screw press to get it apart and assemble. did it by eye and checked it between v blocks. i ran it for 10 years till i had i rebuilt again. didn't vibrate apart, he did a good job for not having a jig. obviously a jig makes it so much easier, were around a grand 20 years ago when i looked into getting one.
How much were the blocks and everything from cometic
Call them or look up on their website
You hafta call them because I did mine quite a few years ago and I don't remember how much they charged me.
You will need at least a 20 - 30 ton press to press the crank, then a dial indicator to true the crank and a lathe or a fixture to set the pressed together crank into to true up with the dial indicator.
Not a job for a "newbie" no offense, but if you know a good cycle shop or machine shop, They can do it for you at a reasonable price.

Ok thanks joe I emailed them and there is a good machine shop here in town.
Sry for all the questions. How long of studs will I need Joe?
obviously a bit longer, being that you are adding 8mm of material. of course the factory nuts sit down quite a bit to give you some room for added plates but If I remember off hand, "don't hold me to that", I think I grabbed studs off of an old Tecate motor I had.
Like I said, It's been quite a few years since I did this mod so I am trying to brush off the cob webs.
It's a really nice mod, once done!
I didn't have the verbal help to guide me thru this mod when I did it so, I'll do my best to help you.
It is a nice reliable mod if you do it correctly. I haven't rebuilt my crank or top end in over 5 or so years.
