HOT ROD CRANK 115 ROD 4MM STROKER

[afireblade929]

I just purchased a long rod stroker crank from Hot Rods today and by looking at the welds, I'm not sure if they are that strong. Has anyone had a bad experience with these welded cranks or knows someone that has had bad luck with them (i.e. crank separated)?

I'm planning on running the stroker crank with an aggressive trail port without the spacer, around 180psi of compression, +5 advance, stock jetted carbs with pods and dmc 916 pipes. Do you guys think i will have any problems with this crank? I really didn't want to send the crank out to get re-welded, but i will if i have to.

 

Any suggestions or advice would be greatly appreciated, Thanks!

Now I was always under the impression that when the crank was welded that they welded all the way around. But there was a post up not to long ago that said the wleded cranks are really basically spot welded just to keep them from tearing themselves apart, at least thats what I got from the posts......... :shrug:

thats correct, the factory weld is a very small weld, and its been known to come apart. It's a good idea to have it redone

Yea, they are two good size spot welds on each side of the pin. Do you really think they will come apart with my setup?

they can come apart with any setup. I have heard of guys with pretty much stock motors that seperate, and then heard of guy with some bitchin setups and they have zero problems. its just luck of the draw. id rather spend the money and know for sure its not going to happen and fuk up my motor and a 400 dollar crank. just cheap insurance

Anyone have a pic of the weld after its been rewelded?Do you weld the whole way around or just bigger spot welds?

if this post had came up a few days ago i had my cases split and i could have snapped a shot. you can do either. but you just want a good storng bead on both sides of the webs

485 Cheetah with 195psi comp. 4 years on my crank with no problems. I've heard rumor that they come apart but I don't know anyone it's ever happened to. Although... a little extra insurance never hurt.

You dont want to weld all the way around because it can put too much heat in the pin and cause an out of round condition. Jeff at fast did the reweld on my 4mil hotrods and i would say there are 2 beads about 1/2 inch long on each side of the pin. It needs to be tig welded by the way. I cant get pics untill sunday cause crank is at dads shop right now and i wont be over there untill then. Maybe somebody can shoot some sooner.

you can actually tig weld it without using filler and it wont change a thing.

Ya, if someone can snap some pictures, that would be cool................
