im having trouble with my crank hub. i made the tool to put it on and i got the hub half way then it would go anymore and it started to ruin my threads. i put a good amount of oil on the hub to help it in. any help would be great casuse im starting to get mad

 

I had to polish the end of the crank and make a key-way for it just to be safe. That may be an idea for you as well...I also had a much longer bolt cut for it so that it pulls on easily without damaging the treads. This site might help also...

yea thats where i got the idea to put it on. its a great website. ill try again in the morning and see if i cant make progress. also the motor just has to be at tdc to put on the crank hub

 

if u have the balancer off u could try putting the hub in really hot water for a while then try.

 

Heating up the hub to expand it would be a good idea. I don't know that the hot water trick would work well though, since the hub will absorb the heat and probably not have enough left to heat it up to expand. What will work better would be to stick the hub in the oven on high for about a half hour or so. Oh.....don't touch it with your hands after that, it'll be a bit toasty!
I've replaced valve guides the same way before. Put the head in the oven to expand it, and put the guides in the freezer to shrink them, then they would slip right in. Now, if you could only get your engine in the freezer...

 

hahaha that would be a funny site. it almost on i probably have a half an inch to go if that maybe if i take a blow drier to it for a while do you think that would help

 

its recommended for the aluminum hubs. u can cause damage on install if u dont boil the aluminum in water to expand them. .001 can make alot of difference.

 

ok so i should probably try that since i had another unsucessful day i just didnt want to take it off haha but owell how long should i heat up the hub

 

Aluminum? My LT1 hub is cast iron.

 

ati makes an aluminum hub for there balancers. its in the directions, read it somewhere and now i cant find it. lol.
