went riding today to get things ready for the grassdrags that are coming up. when i got it loaded we noticed that there were cracks on each side of the cylinder on the back of the jug bolts about 1-2 inches long. my question is can i leave the cylinder on to weld it up?

 

NO,the heat will be hard on gasket's and aluminum aint the easiest to weld.

 

well i think its far enough away from the gasket not to hurt it but im wondering about warping the cylinder ill have the same guy that welded it before.

 

Aluminum is very hard to warp with heat but the heat transfers very quickly and probably will damage your gaskets. From my experience of hours tig welding aluminum, it is very hard and you better get it very clean and a damn good welder to do that.

 

Mine just cracked yestereday was running great and all of a sudden two cracks on both side from the middle of cylinder all the way to the intake.I took it apart today and was wandering if they can be welded and does it last when welded,i hate to lose my port work that was recently done.Has anyone had any experience with ct racing welding theres?Is this a common problem? .Thanks Jason

 

the cracks are only about 1-2 inches long and im hoping that this will work cause the drags are on saturday and the last thing i want to do is tear this thing back apart. does anyone know the best way to go about this on fixing it.

 

I know what it's like to have this happen,mine cracked like dirtdawg's did and during a run down the quartermile.I took it apart to have it welded up to get it ready for a race,plus I too did'nt want to loose my porting nor the bore size.I got it all back together and made the race,but the weld job only lasted the race then cracked again only on the side of the weld.Took it apart again and had it welded,well to make the story short I ended up buying a New cylinder and had to give up the bore size but had the same porting done,I hate to say it but a new cylinder would be safer to the engine.

 

just got it apart and its worse then i thought its clear back in the reed cage ill talk to the guy im going to have weld it and see what he says good thing i got to other barrels that will work.

 

A good friend of mine had his welded up by Trinity. They really built it up on the back base bolts and he had to use different bolts to put it back on with. That's been a couple of years ago and no problems so far.

 

i have never had a problem wit the cylinder cracking,should this be a problem or just a case of a good cylinder its a 603 stroker wit all the goodies
