Here ya go I guess we been too fussy on crank work. Here's how ya do it. View: https://m.youtube.com/watch?v=oIeWAoErOlI
his methods are likely fine for the 100cc scooters hes doing crank jobs on. trues them by sight and doesnt like using a press..
I'm so careful when I pressed a crank. I used centers with dail indicators plus in the beginning a machinists square to rough it in across the balancers. I did have a fixture for the press somewhere. I hope I didn't trash it. I guess it's a scooter crank. He did true it by eye but how close is it. It could affect the bearing life.
so how do you true the crank? ive only ever seen it done by checking in vee blocks with a dial indicator, then making adjustments with a brass/copper mini sledge.
Thanks for sharing. He seems to be skilled in paying attention to getting the pin flush with the crank wheels and getting the true. I would not be using a hammer that much, just like at the beginning he gets the bearing centers off by pounding and expanding them the blows do distort what they hit on other things. The pin must be champhered as he hit it and then it fit right into the next piece.
I was either truing the crank in a vise using spacers to offset the counter balancers to finish align it or in a press to get it close. Rough it in first. My fixture got it close. But my next fixture will be adjustable. I had centers and indicators to check it. I do have the orginal Husqvarna shop tools and fixtures I can borrow anytime if I need them.
