not a typo; it's common to express engine balancing values & tolerances in gram-in units. I have 58 yrs experience machining hi-performance engines. nice video. only one suggestion: when torquing rod bolts, we use a special rod vise that clamps across the wider portion of the shanks big end, to prevent the torsional twisting of the rod seen in your video. This increases the accuracy of the torqued clamping load and bore shape. Also in addition to a ft-lb value, we measure rod bolt stretch for even more accuracy. We also check rod straightness & wrist pin bores. Still, you did a good job checking the Maxspeed rods. 👍

Easy to measure oil clearance one is you measure the size of the journal that you're working with then you measure the big end or where the bearings go then you use a micrometer to measure the thickness of the bearing shell you can use a ball bearing for the roundness just to track the thickness of the bearing so basically you have your rod bearing thickness times two added to the journal size and then subtract from your big end clearance you'll end up with your oil clearance you can even take your big in clearance add the rod bearing thickness times two again then subtract your general size then you'll end up with your clearance

From your video and according to your specs from these rods I would have compared them to a set of stock rods because I bet the stock rods would be in the same ballpark .. For the price, these rods are not that bad.... For a super high rpm/hp build... , because the price is so good in theory, could buy another set of these rods pick out the best and go from there to get the best clearances and still be cheaper than most aftermarket rods out there .. That said you mention that the bearing takes up some of "the out of round" rod tolerance, yes but under super high rpm stress, this could lead to spinning a rod bearing.... (that said this is under the max stress of the rod as it flexes under pressure for a low budget moderate build these rods for the price would do much better than a stock rod)
@sicstar3 жыл бұрын
Ayyy another awesome and well made video incoming!!! :D By that specsheet i'd say the tolerance is a typo. within 0,001 seems more reasonable but is "tight" to say the least. Not measurable at all (usually) in a "garage" since everything needs to be spot on (room temperature exact 20°C? , if it was 15° for that material with 45mm diameter the temperature alone would smack their claimed tolerance out of orbit since it would already by gone by around 0.007425mm *caugh*) well... the TÜV certified material (they mean the base material or the finnished rods?) at least means they should hold up to what is advertised (if they didn't have some . shifting like in the tolerances at least :3) , aka they wont break when V-Tec kicks in yo! The weight differences on those are also quite negligable imo. Counting the pricing of those things in, if you not going for crankshaft bending high HrsPrs or RPMs, those rods are defo a nobrainer. And as always nicley explained. Glad you are around making those videos :) o7

@@d4a circles aren't the only shape that measure the same width at every orientation. There is a whole family of lobed polygons that also measure the same width at every orientation, so measuring width doesn't tell one entirely how circular a shape is. One observable difference is that the midpoint of a cross section of a circle will be the same for every orientation. For other shapes of constant width, the midpoint can deviate. If one can mount a gauge to a spindle, they can check for circularity by measuring the surface as the spindle rotates about an axis normal to the plane of the circle. I am pretty sure this is the method our shop teacher taught us.

Your dial indicator reads to two decimal places how did you decide on the third decimal place you wrote over the video? A guess?
@d4a3 жыл бұрын
It's not a guess obviously. You can easily approximate how far between the two lines it is. I may not be accurate to 0.001 but it's still a fairly accurate approximation.

To claim a rod is a good product there is far more to do than measuring big bore end (even if it's a first good step). This is completely usual to machine a bore with +/-0,01mm of tolerance!!! Every machining workshop can do it. Bores parallelism consistency, main alloy composition, material work hardening and forming defects, small end alloy composition, corresponding surfaces roughness, shoot peening quality, lugs tolerance locations, and rod geometry are such parameters which define a good product from a bad one. The main concern with "racing rods" is their bad small end conformability due to the rod geometry. Moreover, due to the product weight reduction, big end bores subsequently bends more than original rods. This can be harmful and cause to crankpin/bearing contact or bearing wear with oil cavitation but in the end it depends on the given geometry... But the lighter is a rod, the more you are lucky to face this issue with boosted engines. Hazard has no place in such precision and critical components :-) I won't deal with the given screws which are probably completely weaker than promised. Give me some I will quickly tell you what is it about.

One ten thousandth of an inch or .0001” is the standard in the industry for these kinds of measurements. All your factory tolerances for oil clearance go down to a ten thousandth. So not impossible at all.

@d4a3 жыл бұрын
I think you're misunderstanding what mass production means. Something that's impractical won't be cost effective for mass production thus making the mass part unfeasible (impossible). It can still be produced but at dramatically reduced quantities and dramatically increased costs pushing the item outside what constitutes mass production.

@@d4a no, you are misunderstanding what the meaning of impossible is. That means not possible. A standard zeiss cmm will measure .001mm and there are machining centers with better than .001mm positional accuracy. So no, impractical sure, impossible, no.

Only thing I think should be added to this is when doing metrology like this environmental temp should be taken into consideration especially if working in a non climate controlled shop. A 100mm bore can change .02mm per 20 degrees F of temp change. (Obviously material and bore diameter dependent) Your sweater and beanie made me think you're not working in a climate controlled shop. Here most all metrology values are done and listed at 70 degrees Fahrenheit.
@d4a3 жыл бұрын
You definitely have a point. My garage definitely isn't climate controlled, it was around 10-15 Celsius (that's 50-60 Fahrenheit I believe?). When you don't move much it gets cold hence the sweater and cap. I also don't take cold well 😊. When I can I avoid measuring on really cold days as it definitely can impact measurements, but I think this was an ok temp.

This is an incorrect way of measuring the crank bore. You should have torqued the rod around a ground 45mm mandrel, this would represent the crank. The tolerance of the dial indicator is also far to great. You would be better checking twist bend and pitch which is not stated on the on the box (this is the relation of the small end to the large end bore).. Look forward to see more.
