I had a lifter break late last year and last month had a lifter tie bar come off thus ruining the new cam. Tie bar was a comp cams removable(big mistake I know). I have always used the lifer with the non removable tie bar in the past, but got a great deal on these.

I have never had a cam repaired always replaced them. But custom ground cams are pretty darned expensive. And, this one has worked really well..

So, what are the repair opinions and where to go to get them done?

If I remember right Bullet said it is around $100 to regrind them if they are not damaged too bad.

I'm thinking both of mine would have to be welded before regrinding. Then of course heat treated..

At that point IMO you are better off buying new one. Not sure how much weld,regring and hardening would cost but can not be much less than new one.

I have 1/2 dozen or so old cams on shelf and tried getting them reground but was pretty limited on much change in duration or lift.So by passed that idea.

I do not think Bullet charges anything to check it but it sounds like if it is that bad time for new one.

Bruce,
Already had a new one ground, I was just thinking about getting these reground/repaired.

Paul S/Q,
Good to know. Thanks

B.C.
Are you saying they can't re heat treat one or that Bullet can't?

I would think where ever they get their cores from would be able to heat treat them.

Years ago I wanted a set of Pro Gears for a 8 3/4 Mopar. I talked to Richmond gear and was told they could send a set of their street gears back to heat treat and they could re-treat them.
I just figured a cam could be done the same.

Sounds like it may be time to start calling around.

Thanks for the input.

Dave

LSM replied to my email this morning.

Like everyone has said, it can be re ground if it hasn't went through the heat treat. If it has then they are scrap.

They cannot be re heat treated.

So now I know.

Thanks

Dave

Yes.. I was hoping they could repair then re heat treat them.

But it seems they can't.

I believe that. We were in a hurry on a rebuild and Bullet didn't have our cam on the shelf but they had one close that they reground into what we run. We ran it around 50 runs and I pulled the intake to look at the cam and lifters and found a lobe on the cam that was getting worn down. We didn't see any other problems so we sent pictures to Bullet and their theory was when it was reground it went past or almost past the hardening.

I would think that heat treating a cam again wouldn't be a problem just to make the lobes hard. What is a problem is that it won't stay straight and you don't have material on the journals and lobes to grind it to where it is. Then the only option is bending it to straighten it. Not what I want done to my cam. When new they probably have enough material to take off so that it makes it straight after heat treat. Just a thought.
