gm 430 steel crank spun balancer off if snout got bent can it be re straightened. ? if so what is approx cost. thank you

a friend bought a gm crank from me long ago that was a lil wobbly and he had it repaired . i would think a snout could be done also if it were a minor twist . dont take my word for it though . i usually buy new parts if i can .. id wait to see what wolf has to say mike is a straight shooter .. hope you can use it .

still no info . hang in there someone will get to you . they always do

noname,
If the damper spun off, the snout is probably damaged. I doubt that it is "bent" but is probably worn enough that a new damper will not have the proper interference fit to stay in place. The only way to know for certain is to measure the crank snout with a micrometer. If it is not worn, you should be able to put a dial indicator on it and turn the engine over by hand to see if it in bent. Either condition can be repaired by a good crankshaft shop.

Hi There,
As Bill stated, if the damper came off it probably damaged the crank but I highly doubt it bent it.
If the damper worked or spun before leaving the crank will probably be damaged but it can be built back up just like a journal by a good crank shop & reground.
I am assuming this is a Buick?? In any event if it broke the damper & didn't spin on the crank it may be ok, no way to know until you mike it.
They usually destroy the keyway & damage the snout before leaving though,,, :(

Good luck ;)

I like the mic idea and a run out with a dial indicator. I'd have to look up the tolerance of the run out there but if the balancer goes on ok and it mics ok then the next test is to see if it will balance. It won't if things aren't straight enough.

Good luck

assuming i can find a shop here in oregon that im comfortable with since my ability,s are limited what is a ball park figure on something like this if i take it to a shop. thanks again guys

call your machinist up and ask. They don't charge me anything just to look. Shouldn't be over 50 to check it out but that's here. About 120-150 to balance here.

I have seen this done AND done it too, but don't know how well it will work on a cast crank if it is cast?

Take a sharp pointed center punch and ding heck out of the snout to raise the metal on it's surface. This is a lot like "knurling" a piston. Then use Lock-tite red or some other strong glue to help hold a new/different damper on better.

I will say it isn't the best way to do it but works really good for us "shade-tree" guys!!

The crank in both my .040" over, 327 that I gave my nephew AND my old junk 301 was done this way and I drove the dog-sh-t outta both of them!! Especially the 301 over the 327!!
