So a while back by pulley got loose and i guess it did a little damage...Anyways for some reason the guide slot that hold the pin to line up with the pulley has been chipped. I want to know if it would be ok to weld the guide back so it hold the pin?
Would that be a good fix or am i looking at a new crank?

 

ive seen people wh have just filed it down and than installed a larger woodruff key.
also a picture would help.

 

sorry, no pictures

 

Keep in mind that the crank bolt holds the pulley from spinning and the key is for alignment only.

 

so i guess i should be ok then?

 

i cant see that being a problem dude , as long as your talking welding to fill in damage and renewing the slot with a grinding tool like a dremel. are you talking welding the key to the crank? well , either way i cant see it being a problem really , make sure its strong and the pully fits tightly where its supposed to. tig welder would be mint for that job. a 220 mig welder at least though.

 

woodruff key is not just for allignment.

 

welding to fill in the damage, renewing the slot and then put a new key in

 

perfect.

Funny, because it is....and when its not....it shears off. The bolt threads into the crank and the washer hits ONLY the pulley (not the actual crank itself), it is this force that holds the pulley from spinning...not the woodruff key. I can assure you that no woodruff key and just a bolt holding the pulley on will not allow the pulley to spin, however just a woodruff key and no bolt = sheared woodruff key/busted *** crank like Baron55 has.

 

It would seem to me if you are welding something to the crank that it would need to be rebalanced, otherwise it could result in premature bearing wear, or worse the oil pump could fail since its the closest thing to the front of the motor..

 

How deep is the chip compared to the depth of the keyway? A picture would really help.

 

doggs right a pic would definitely help. as far as balancing goes , i dont think this will affect it any , lol.

 

what do you mean a little loose and did some damage? its either tight or loose. and you do need the woodruf key. send pic or be more specific.. as far as welding it! I would look for some other alternative and that be my last resort. its just my opinion. GOOD LUCK!!!

 

ive had my crank pulley launch off on the highway and never chipped a crank.
and what are you talking about washers touching pulleys? wtf??
not just for allgnment do it right weld it file it, take off oil pump to ensure the frontmain seal doesnt burn up when welding it
as for balancing it should be just fine, id get urself a dremel tool and a tile cutting bit and file away a notch for the woodruff key and youll be good.

 

He means that the pulley is wide enough that the crank does not extend past it. so torquing the bolt down would be enough to keep the pulley from spinning. i would just stick to jb weld for filling in that slot. i heating up the crank doesn't sound like the best idea to me.

 

well i didnt get a chance to see it but it was sent to a machine shop..I spoke with them and they said it was very fixable and they filled in the slot.
