HeadC1 bought his wife a 07 brute wit a motor that had a spun rod bearing (got a great deal because of this). Here are some pictures of the motor goin back together. I wouldnt call this a "how to", more like a how NOT to put a crank in a motor, although it seems to have worked ;)

a lil brute PORN for yall


Using the new parts washer to clean the cases


using a hammer as a press, notice our nice block of wood to suport the crank in the middle


what do u do when a hammer doesnt work, get a bigger hammer (also works for removing ur old worn out crank)


the new crank is in


the rods wit new bearings are now in


Head putting some RTV on all the edges


the liquid encouragement to get the job done right (im a Bud Light fan myself, but free beer is always good ;))


the manual that trys to keep us from f'n the whole thing up


put the bolts back in after putting the cases back together


that was as far as we made it last night. stay tuned for more action from Team BS HQ

They say you need to buy 2 $150 crank jigs but a 2x4 fits perfectly between the crank lobes.

All in all seems to be going well for our first v-twin rebuild. Hopefully we'll have it cranked sometime this weekend.

i plan on takin more pics as we go. its hard to get pics of everything, but i was tryin to get pics of the motor before we covered anything up.

i wasnt sure if this was exactly a "how to" thread, so i didnt put it in there. if the gods feel like it is, then feel free to move it lol

One tip for those going to try to install the crank themselfs.... A butane torch is your best friend when doing this. Heat the crank case up where the bearing goes real good and the bearing will drop right in. Once the bearing is in heat the inner race of the bearing some and the crank slides right in.;)

Awesome, I may have to tear my little brute down before to long, its got a slight knock to it (I think its the rod bearings by the way it does it and sound it makes). Runs great so I guess i'll see with time!!!

another tip on installing a crank is that you put the crank in the freezer for a few hours and heat the inner race like stated above and the crank will just fall into place on the bearing. I did a crank on a 2 stroke that way and it work just perfect. any one ever hear of that little trick?

Well we cranked it up Saturday night. I didn't have the exhaust hooked up or the breather box on so I only ran it for a second, just wanted to make sure it worked before I put everything back together.

I've heard of the heating and cooling before and think I'm going to try it next time on the crank bearing in the left side case. Its the one they say you can't change, that you have to buy a new case to replace it. I'll also try it on the main bearing on the right side as you stated.
