That is a very nice crank balancer. Finally, it only occupies space your already have instead of makiing a permanent location for another piece of equipment. It almost looks portable.
Nice vid! We have a DCB-750, software is circa ~2004, and no drill press mounted on the machine. It's a royal PITA to have to move over to our TCM-25 just to drill, then set back up and spin. Takes any profitability out of the job haha
Still can't find a good beginners vid for crankshaft balancing. What are those things that are clamped onto the shaft? How do they work? When I say beginner, I mean BEGINNER ;-)
Bad thing is you do not recover the cost of the 1st crank being bad, poor mfg quality right there, hopefully they treat you right on the price of each crank LOL
You'd have to x-ray that to find where the problem is, and then the only fix is to cut out the porosity and weld repair it. That one goes in the scrap bin unfortunately.
It doesn't have to be perfect. If its heavy remove the material from the outer edge of the throw, never drill it unless you absolutely have to.. a couple of grams is nothing. You might get that much weight when assembled when there is oil sticking to the bearing
@@powellmachineinc3179 Static vs Dynamic Balancing. Static is repositioning the center of gravity to align with the axis of rotation. Dynamic is adding or subtracting weights / counterweight to ensure a precise motion and minimizing vibration. A crankshaft is nothing but vibration. On a V 8 engine you have two opposing pistons firing at a slightly different time on the same rod pin. Now think about it, if you are balancing and blueprinting the engine to get the maximum amount of performance out of it, would you want to penalize it by leaving in necessary weight on the outside of the crankshaft? If you are looking for performance the first thing that you want is to remove mass. Unless you want to use the engine in a truck for towing or pulling tree stumps.
Shop owner here. I have a DCB 750 balancer. It does an awesome job for what I do. My question is do you feel the imbalance angle is important? I always try to end up with my imbalance 180 out from the throw on each end, what do you think and always try to get under 1 g
🔔😎🇺🇲 1:20 I missed how you are squaring all the weights to the crank throws centerline. 25 yrs ago I did all the balancing at the race shop. Your machine is AWESOME.👍👍👍
