Should i take my crank to get cut or just buy a new one

[Vr4junkie]

I just took off My Crank and one of the journals is damaged so should i get it cut or buy a new one??

Put a heavy-duty impact gun on the large nut head and spin that off. Then, if the gear won't pull straight off, use a bolt pulled set and pull it off.

I just pulled my engine apart last night and didn't have to use any puller. You do need to get the big bolt off. I was able to use an electric impact as my air impact was at my shop and I'm doing this project at home! Good luck.

OK I have an Electrical impact wrench so what can i use to hold the crank still i have a bar i can put in to hold the crank still will that work i just want to make sure never done this before and don want to mess anything up

you shouldn't need to hold the sprocket if you're using the impact...

ok i took off the crank shaft and one of the journals is a lil damaged the other ones are smooth ... So my question is this what are my options take it to a machine shop or buy a new Crank i heard somthing about our cranks about getting machined not sure though so tell me what you guys think

I understand that these cranks are nitrated. What that means is that they are ground and then hardened and then polished. I used to rebuild a lot of Porsche engines that had nitrated cranks and never had much success at having them ground locally. I might be in the same shape with my crank, but I haven't measured it yet. No scoring, but I had the #3 main not getting oil for about 400 miles. I'm planning on making the trip to the machine shop tomorrow and will give you an update on what they say.

^^^^

Correct they are nitrated and it only goes so deep into the crank. When the crack in ground it can take most or all of that hardened layer off. A lot of people have had good luck running cut cranks but for me I would never run one. Used cranks are cheap enough that finding one should be easy and would be worth the piece of mind to me.

Boostedinza and rdomeck thanks for ur opinions....im probbly ganna go with a good used one

Well, I have measured and remeasured and have found that I don't have to have any machine work done, so I can't give the advice of the machine shop! I would check and make sure that your crank doesn't just have the bearing material built up on it. They are hardened and what you see may be the bearing material and could polish out? Just a thought!

now that you mentioned that I have noticed there are some spots that are some what smooth and have a bead like feel. And on other spots it feels like tiny little knife cuts. Glad you mentioned this might take a trip to the machine shop tommorow. That would be awsome if it just needs a polish /ubbthreads/images/graemlins/laugh.gif this is my first time taken a motor apart so this is all new to me
