WELD CRANK OR REPLACE?


J12480

Recommended Posts

I had mine done at SamCo before they closed, the welds cracked before I even installed it. I heard it does not matter though, cause they still keep the crank from sliding apart. Cost me $90 and they threw in some toomy needles. you will also need a Seal Kit. About $20-30.

 

If I was going to have it done agian I would have shipped it to Jim @ Passion Racing Engines. He uses special rod material that does not crack and holds up better in the long run. I don't think you will find any local shops that will use this stuff plus they are way too expensive. I'm sure you can find someone to weld it, it's the truing equipment that not many people have.

 

Veys told me all my bearings were shot cause they had too much play and wanted to charge me about $300 to rebuild a crank that is not worth rebuilding.

 

Duncan Racing would not weld it unless they re-installed it into my case for about $4-500!

 

Scribs said he coudl do it but he just had them done my Duncan or some other shop and his price was too high also.

 

:(

 

 

If you replace it might as well replace it with a stroker motor and modify the head to work for a 4 mil stroke!

 

Oh yea, I asked SamCo about the play in my bearings and they showed me a new one that had the same amount of play in it, so I guess Veys was just trying to get me for a new crack...No Problems so far!

I just took my crank to Duncan and they trued/welded and replaced the outter bearings for around $150.00.  I dont know why they wouldnt do it just bring the crank and set it on their counter not like they will refuse it unless they changed their policy a bit ago.

How long ago did you have this done and who did you talk to? Sound like the best option so far. Thanks

Buy a Hot Rods, theyre trued within .001'' and that is sufficiant reliability for any motor under 60-70 hp. Its also a much better assembly than most machinists can rebuild the the stock crank to. Welded is good, but ive heard if it is done shitty it will be out of balance.....and chances are that some okey in east county will do you dirty on the welding. And as stated above its probally gonna crack anyway. Im in the same boat, and im going for a Hot Rod after this season.

not all new cranks need to be welded since they are not pressed together to begin with..

 

I called duncan when I got my 12-port I had the crank in my hand they said they would not weld it unless I allowed them to install it.

 

$150 is alot for a crank weld too...

 

Then Again Duncan Racing pisses me off every time I go in there shop.

 

They refered me to SamCo since it was not worth their time.

Good points, I've always heard that a welded crank cannot reach that true of a tolerance (.001') The less true the more HP it costs you.
