Schubeck lifters
 

What's the proper break-in procedures for these lifters on a solid lift cam? Oil, rpms, spring pressure, etc.
This is my first times using these and I have been told that break-in is much like break-in using roller lifters, is that correct?

There is no break in procedure. But unless you have the full ceramic solids, I'd be very careful with the solid, or hydraulic ceramic bottoms. Cost me a good engine.

What ever you plan to race with CK the lifter bore .0017 to 002 and keep up with the pressure

Re: Schubeck lifters
 

No break in proceedure, set the valve adjustment and run em.
Be aware if and when your engine is in valve float, and run enough spring pressure. Nothing wrong with these if you pay attention. Many racers run these for a long time with positive results.

Jim, as the other said no brake in necessary. What we did when we did a cam change was take a spring shim out, warm the car up a couple times, checking things as we went. Then installed the shims back in to put the seat pressure where it needs to be, then run it. I know these steps are not necessary but I was extra cautious. We run a sbc, hyd set up. I know it is a different combo, but we run shubecks.

I just had a Schubeck lifter loose it's puck, the engine got f**ked. Never put them in any engine again. Use tool steel lifters for now on.

Like Todd said you have to stay on top of spring pressures with the puck style lifter. If you dont the cams are so aggresive these days it actually throws the lifter off the lobe, when it comes back down and makes contact the puck gets knocked off. Im extra cautious about spring pressures simply for that reason and probably have WAY to much, but (knock on wood) ive used the same schubecks that Jeff Velde gave me 10 years ago that came out of one of his engines. Same thing applies for the roller lifters, thats the reason they break the wheels off, not enough spring pressure and everything starts bouncing.

Warning!!!!!!!!!!!!!!! if these are Schubeck dont use them. With Schubeck you dont know if they are the US made or the overseas ones you could have a real problem on your hands. If they are the Smith Machine ones your good to go. Chuck

Not true the Smith lifters have almost the same failure rate. think smith made the bodys or subecks.
