How To Balance an Engines Rotating Assembly #DarkMatterPikachu #FairmontProject

1. Did he weigh n shave the pistons

2. I weighed my parts: I marked them with a sharpie: the next day my parts did not weigh as marked. I was trying to weigh them to the 10th.

3. i have just watched this on 2021! thanks!!!

4. Is nobody commenting how Kevin looks like Triple H?

5. Is it just me, or did John Favreau open a machine shop? I enjoyed this video immensely BTW.

6. I worked at an automotive machine shop in the late 70s, it was done the same way back then. We charged $80 to $85 dollars to balance a v8 unless a lot of metal had to be added to the crank.

7. What a great learning experience to watch an expert do this difficult job. I wish Eric had used a drill gage to grind that big drill perfectly on center with correct angles on both cutting edges.

8. Really well done however measure the material of the crank you are going to remove first then determine how many holes you will drill. You were somewhat limited to how many you could remove evenly after you decided on two holes. you will have more of an effect on drilling 5-6 holes that are evenly spaced and a bit shallower than you would two or three very deep holes. Structural integrity is greater also by drilling smaller diameter holes. You do not want holes intersecting inside your drilled holes. Well done though with the explanations and kind demeanor.

9. To bad the bald headed guy wasted his time on learning a useless skill like this instead of taking gender studies or lesbian dance in college lol.

10. Hi, I love the videos. I have an odd question. I used your videos to pull my engine (thank You) from a 1965 Buick Speacial 4.9 (300) v8 to upgrade to a 1979 Buick 350 from an Electra but the original 1965 – ST300 2 speed trans is a must keep my wife loves it, so its up to me to make her happy.
    ???? Question: in theory of course… if i go to a machine shop and have the 350's crankshaft balanced; by having the Flex pllate weld-weighted & balanced like on your video-
    Q: will the 1965 Transmission's-ST-300 operate properly after being bolted to its torque converter?????
    Or is there another step i will need to do with the trans too???

11. where did he get the shown math of all components from to make bob weight … the bob weight will be incorrect if he follows whats on the card … he needs 2 bearing weight and needs 2 big end rod weights to make Correct bob weight .. i hope he fixed his calculations

12. My 427 tall block strokers (2) had to use 454 external balance flywheels (drilled in a few places). The harmonic balancers were drilled, crank, flywheel, the whole thing was a balancer's nightmare.

13. Very cool

14. Didn't know this amount of work was involved in engine building. Insane! Cheers Kevin and Eric!

15. How much should people expect to pay

16. How much should a good machine job charge for doing a balancing??

17. Great video with the exception that you talk just a BIT (pardon the pun) too much. 😉

18. Just had my entire bottom end built for my car so watching this video is really awesome to understand it more. These guys are modern day wizards imo. Just sucks most good ones take 2-5 months to get parts and get it done correctly. Usually you just get your bill and see prices of balancing and cutting and honing but this changed my entire thought process on the 4k bill i payed lol. Sucks also most of the best guys with shops with all this knowledge have noone to teach and learn 40 years of experience. If anyone needs a 2jz i highly suggest brian roche in maryland. Hes the best on the east coast for sure

19. Good knowledge .. but it’s as good as the accuracy and precision of your balance, and proper routine calibration, if it’s no, then there is no point ..
    The way the balance is sitting on the metal base with its front legs sticking out in the air, will make weighing extremely inaccurate.
    A properly calibrated balance will have a annual calibration sticker, and the air bubble needs to be checked each time before use to assure the balance is sitting FLAT on the surface and not leaning forward over the edge as the balance in the video is.
    I was at one of my jobs the instrumentation manager at a large pharmaceutical company and supervised the calibration and maintenance of all equipment.

20. 26:19 No games in the machine shop Eric

21. How you got mass valve to balance engine ?

22. Very informational video!

23. how much did balancing cost ?

24. all the mechanical engineers like this

25. Too much drilling, I'm sure his oil foams .

26. Honestly…one has to be a complete idiot…to make the assumption that a machine shop would not clean the crankshaft impeccably before assembly.

27. Eric, this is BEST video, explanation and exposing the mystery of crankshaft balancing on YouTube ever. I still can’t exactly gasp my mine on the procedure of positioning the weight at the correct location of angle of the weight clamp blocks. I get the weight of two loaded rods on one journal, but the position has to be a relationship of the two at the top when the stop, as the bottom is still rotating. 98% of my visual skill-set has captured and saved to long-term memory of the entire process. I can only save enough in an early medical retirement from long days of hard work to get into a machine shop to get a clear idea of the counter-weights position to be clear, but Eric, you and you machine shop buddy has taken me miles on the reciprocating assembly & machining process in the back room. I was lucky at 13, to work for a two man shop (Owner and me) who told me he learned more about engines in 7 years in a speed shop machining back room, than he learned in 28 years in a Chrysler dealer. I was the apprentice sponge and his gentle even manner taught me well. WoW! When I grow up, I want a 20” wide belt sander with a 3 foot bed. Thank very much, so enlightening Eric!

    PS. June 17th 2020 is my last lumbar fusion at the L3-L2 level at my shoulder blades. The rest is fused and makes it hard for a 6’3” guy to pickup anything dropped. It’s just one of 3 more metal parts I need, at 62!
    Pain sucks and working from 7AM to 9PM for decades, isn’t the whole reason, but most of it, except for my lumbar caused by one boss man. Hope we never meet.
