Thanks,
You can add a shim if you need to adjust the offset of your flywheel but it is not required. Also if you do add a shim it needs to fit the crank perfectly and not be larger than the inner race. I have seen many times people use large thin shims and they get bent back ( towards the bearing ) and eat up the bearing seal.

Default Will you accept?

hey lance,

wrote you you a message here about my B5 recently that I had wanted to send to you to get rebuilt. Wanted to know if you would mind if I sent it to you in pieces? Iíll explain..... I donít disassemble my engine often, and want to get a repetition in doing that. So before I deploy, I wanna strip it totally down, inspect it, and learn a little more about the inner workings of a nitro engine. Would you have a problem with me doing that, and sending it to you completely disassembled to get worked on? Just curious.

Thank you so much for the info. No shim it is then!
