What we need is lifter prevention
Yes, Lifter failure prevention....
Does anyone know or can someone find out what the hyd flat tappet lifter hardness should be so we can test them first? I have a hardness tester. Most engine shops do. I've got to find this out and soon. Not worried about making a small mark on the side of the lifter close to the bottom when testing. Easy to smooth out. |

First, you need to have some understanding of metallurgy and have knowledge of the material you are testing and any finishes and treatments. Many materials will change its original properties after being exposed to chemicals, heat and mechanical impact. |

Re: What we need is lifter prevention
I need to let you all know, I was a mechanical nuclear inspector for 7 years. Working with all kinds of exotic metals. I used to teach guys how to use a hardness tester. So thanks for the dire warning of what I might need to know, but I got it covered. And thanks for the numbers Terry.

Re: What we need is lifter prevention
Soo I would guess Lifters failing is still an issue? I have read Lifters are too soft and failing. Is this a material problem or a machining problem?

Re: What we need is lifter prevention
Lifter failure is definitely still an issue. That being said when you read all of the stories online of how people are wiping out lifters left and right, I would personally take them with a grain of salt if they don't specify things such as if they used proper assembly lube/break in oil, valve spring pressure, and break in procedure. I do however believe that there are some lifters out there that are inferior to others. I recently made some discoveries regarding who manufactures certain brands of lifters nowadays and was able to buy new Johnson solid flat tappet lifters even though Johnson does not sell them direct anymore.

Re: What we need is lifter prevention
I was smart or lucky enough to have kept piles of old lifters thinking I'd buy a rerfacer for the budget builds. Well, you can't find one of those machines for squat. Been looking for 25 years. Zippo.
But a local shop has one and even tho it isn't cheap, I get to use good old metal without worrying about problems. A lot of work but knock on wood, no problems so far. |
