I need to rebuild my crank , one berring is bad / anyone wanna do it ?

[Budweiserallday]

I just got the motor tonight , I was told it was a 4 mill , going to tear it down tomorrow and see , how do I tell if its really a 4 mill and if so does anyone on here know a place to send it to get rebuilt? Trying to get something as cheap as possible (I want to sell this bike after I rebuild )

Also do I have to use a special type of piston , was told the bore was std.( I've never worked with anything but stock before) Thanks for the help

wildcard does good crank work. give them a call. Pistons will depend on rod bore and such report back after tearing it down

When you get it apart, look at where the pin is on the crank. A stocker is like about 1/8" in from the machined ring (about) And the 4 mils have the edge of the crank pin pretty much on the edge of that raised ring..

 

I can definitely set this up for you-let me know if I can help ....

Gonna tear it appart today , will post pictures later . Thanks y'all for replying

[trickedcarbine]

I hoped you checked stroke before tear down

[KaN Powersports]

I figured he didn't have the means to. He is going to send it out to have it set up-who ever ends up building it can check all of this out for him.....

Unless you got the bike for free you will loose money.

Crank works is the best for rebuild IMO but it will run money might be better off buying used crank

Precision Power Sports can rebuild also. They did 2 of mine last year.

[Budweiserallday]

I've gotten everything off the engine besides flywheel and stator , and ofcorse the inside of the flywheel is stripped , can anyone help ? Idk what to do now

[J-Madd]

Weld a flywheel puller to it is the only way I know of. Someone else may have a better idea.

[Starwriter]

Yep, time to break out the welder. Be sure to clamp the ground on the flywheel puller. If you clamp it on the cases, you send the welding current through the bearings.

^ now that's forethought

brandon at wildcard did mine and he does great work. give him a call he will work with you on the money part.

What's the going rate of a 4mil Hot Rod crank rebuild?

I've got a new pair of rod kits already. Does it matter that it's been welded?
