Is it possible to put a crank from a tca into a tcb What I want to know is are the physical dimensions for bolting in the crank the same

 

I believe the pinion shaft is different, plus no sprocket to drive the balancers.

Only difference is where the bearing race is on the pinion and that can be moved, and the lack of a sprocket.but it can be moved also.Plug an oil passage move a bearing race and 14 pounds of whirling crap stays on the floor in the garage.

 

Chad it would be easier to send your crank to hobans and have them remove and balance it for you. plus weld and plug it .
i run a b crank they did and not bad but if i had to do it again i think i would leave the balancers in.
oh yea and i used to spin it up to 7 grand also but set the limiter back down to 6400 just because nothing is working any way at that rpm.

 

I got the screamin eagle 4.375 #23600.and put it in with new pistons se 22144-08a. I was amazed at the depth of the grooves in the counter balancer tensioners. They were at least half way through. In only 2400 miles.We will see but I think Ill like it, thanks for the advice though.

 

some pics of the balncers condition at 2400 miles

 

never seen mine but i have to agree with ya. lets wait and see. i would send it out to hoban tho .

 

I'd have to agree with that, whether you plan to keep or trash the balancers.... send to Darkhorse.
