thats why you measure the pin hole in the rod before you cut, you say to make the bushing without measuring the pin hole
with .003 press your extremely likely to crack the bushing have you ever pressed something together? end of story its not the right way to do it,thats why the right up says .0015 -which is a standard press fit for a reason....
and some people dont have to pay for bronze

The machine shop probably honed the rods until they were within .001". Pressing .003" into a .827" hole is going to be difficult.

If you're not sure on your rods you can order them .003" over then hone the rod till you get it within .001" .0015", IF you're ordering the bushings.

If you're going to machine them yourself, like I might do, .003" is too much to try to press in and would probably get fucked up while pressing it in. You think "oh it's only .001". .001" is more than you think when we're talking about a press fit.

Not for $7 a rod they didn't. Not this place. And that includes shaving the big end down.


I mean screw Crower. It's not like they know ---- about connecting rods or anything.





Also, cupcake, again that table is not set in stone values. It DOES NOT take into account so so so many factors that determine interference fit. Two of the major factors are modulus of elasticity of the two materials. THOSE ARE MAJOR FACTORS.

not saying they dont at all....just you dont have a clue end of story

I'm not the one saying 3 thou is too big to press fit bushings. You just THINK you know what you are talking about because you may have taken some classes or talked to some people, but in reality, you know just a little about the subject which makes you cocky and a douchebag.

Do yourself a favor, stop.

Well I'm not a lazy ---- and I'm going to do this myself. .001" is more than plenty to hold the bushing in. .003" is difficult to press in in such a small hole.

Besides you think it's that difficult to use a honing tool and an Intrimik on a rod?

never took any classes but i have worked part time in machine shops since i was in middle school and have a pretty good concept of what i am talking about, but you were saying 3 thou is awesome because crower did it and the fact that i called you out for never machining anything is why i might come off like an ***, but in reality im trying to help others who are trying to attempt this by giving them correct info because not everyone has the extra machining help as i do. just ask E-bola, oh wait never mind he doesnt agree with you so he must be a douchebag

You don't have a clue what is the correct interference fit for this application. The simple fact that you rely on a basic chart that doesn't take into account some majors parameters or even provide the parameters for it's base for the numbers shows that you really don't know any more about it that I do.

Also, I machine plenty. Maybe simple brackets, adapters, etc, but none the less.

chart was just for refrence and its more common sense than anything, jeez....please tell that to half the guys that i work with or my dad who wrote the program
try machining a bore 3+ inches dia by 15 inches long and keep it within .001 taper because thats what they do , ill take their info over yours any day or just about anyone

whiterice

ok. so have your dad do it for you and shut the ---- up.
will it work either way. it should depend on the material, but most likely yes.
After a few years, I'm still running the LS rods Madmax did for me.
Apply your concepts and post it up. I think HMT benefits from all examples.
