This is a masterful demonstration of a practical skill, with maximum content, with minimal ( NO ) verbalization to confuse the presentation. This is a fantastic show of using maximum skill, and minimum equipment to preform a precision task. I love your crank test stand, a work of art, all on it's own. Your photography is magnificent, and shows everything needed perfectly !!! Congratulations !!! Tim

Amazing that the press plug is good enough to lock it all down. Also amazed the builder left all the rust/corrosion on the crank. Could be that it looks worse on camera.

great vid, just wondering why you don't heat the wheels, freeze the pin and drop it together instead of pressing?

[@Anthony9592]

Excellent Job Brother!! Our Royal Enfield 500 and 350 engines have similar crank pin.. I had changed the same in my Royal Enfield 500. Unfortunately, many riders of Royal Enfield experience the same problem. Watching this could perhaps enable them to know the delicacy of this job..

Was wondering if the con rods were the same weight as the old ones as to retain the balance. Could be that the balance is better now.

[@nikolaiownz]

You really should indicate the crank Futher away from the roller bearings to get a more accurate reading. The ends can have alot of runout and only show little next to the bearings. Anyway nice video and good job.

[@PaulXchannel]

OK. Thanks.

[@nikolaiownz]

@@PaulXchannel it's a beautiful fixture. Did you make it yourself ?

[@donniebaker5984]

@@PaulXchannel you read your dial indicators at the main bearing journals just like you did it or you are wasting your timid if you don't !!! It doesn't hurt to check the further trueness of the drive socket side and the opinion side shafts but run out at the main bearings to get it right must be set at "0" zero .and check out Precision balancing Company of Indianapolis Indiana.. Where you can send your crankshaft zeroed out with no rods attached piscina near-complete rotating assembly and they will weigh out each part in one gram and send you a paper on that Daniel take a shot box fastened to your crankshaft and fill it with chhatre exactly what your rotating assembly will weigh Alan Hale spend balance it to whatever RPM you want to run as maximum on your engine build and betting you won't believe the difference it makes as the front tire will not jump up and down on the pavement anymore when it's idling and when your roll it on it won't feel like a Harley anymore it feels smoother than a Japanese bike and you'll gain a whole bunch more power as there's no more inertia of a crankshaft trying to come out but just rolling free and balanced. I don't need to tell you that Harley doesn't have time to do all this and still sell a motorcycle at the price they do as no other manufacturer does either. Manufactures build a perfectly balanced engine to start with as a prototype and then copy all the parts and weights after that and if it's balanced fine if it's not shakes little bit so what

[@donniebaker5984]

If you do it your way the main bearings can have some hop and wobble in them at least about a thousands or even more and you're wasting your time ...if the sprocket Shaft or the pinion shaft is wobbling after you have true the main bearing journals get new parts and do it again

If you would have used a positioning jig you could have eliminated the hammering. You still would want to check it for position. But a great job none the less. Also you need to face grind that Hammer. The way it is now it could spit something at your eyes.

[@JeffinTD]

Nice job and awesome video. I’m kind of shocked those cranks would ever stay true from the factory, considering the load on just a press fit. A taper fit and a nut, or welding the pin to the flywheels I’d think would be more solid.

[@peejay6855]

I would think that after the crank is centered and placed in the case supported by the main bearings, there is no place for the crank to twist out of center. If it does then I expect that you have many other problems to worry about.

[@JeffinTD]

@@peejay6855 Yeah, the bearings support the crank, but it wouldn’t have to flex much to end up with runout that could damage gear drive cam or even the oil pump.

[@1crazypj]

They have a pretty tight interference fit from the factory, there used to be promotional video's about it with the special 150 ton press HD developed. It's supposed to take a minimum of 50 tons to put them together but I have heard many are around 20 tons? I've done hundreds of the taper pin/nutted HD cranks but always kept away from the pressed up ones.

[@garygruber1452]

Welding the pin to the flywheel is something we did back in the 70's and 80's on much simpler cranks

[@patrickhollis5332]

Yea a lot of companies do press and weld them with a bigger pin Harley should’ve done that to begin with like they did before and they did on early twin cam for few years than trying to save little money they did the pressing it’s crazy the runout they have on some

[@andikkristian6023]

Perfect...

[@romerkilic7895]

Graet Jop! Greetings from Istanbul.

[@jonnymac8925]

What are your thoughts on welding the shaft that you pressed in to the flywheel assembly that holds the bearings/rods? I know people do it to prevent runout on high RPM builds and I want to have a nice reliable xr1200/xb12 crank built for my Sportster build to handle a beating. Your work is amazing!

[@PaulXchannel]

Thanks. Welding the shaft ???

[@donniebaker5984]

@@PaulXchannel you can weld a quarter round the crank pin to the fly wheels so it can never slip .and use a tig welder for a very small and narrow bead and not much penetration so it can be ground off with a die grinder. For future overhauls ..of the last of the all roller cranks from Suzuki came factory welded pins as a lot of them were twisting cranks at the midnight drags in the ghetto on 36th street Indy back then

[@1crazypj]

Best thing for a reliable Sportster is keep it between 2,000rpm and 6,000rpm and don't fit drag pipes as they lose power being designed to work at 9,000rpm on XR 750

[@blakegriplingph]

The scarred crank pin may be caused by not enough oil being circulated, idk. I've read that some people balk at Twin Cam motors due to their supposed unreliability. If you're going to overhaul one you might as well swap the chain-driven cam assembly with a set of gear-driven ones as cam chain tensioners on them do have a litany of issues.

[@midnightmc3096]

Runout is too high on most of them to take gears.

[@kasquaskannachehukapapansk9857]

I developed a method where the wheels are trued zero while pressed them together without hitting them with a copper hammer and truing them. Also why did you not replace pinion shaft when it was apart for a new bearing surface and oiling upgrade?

[@arthurcutaiar9994]

Its only a 3 piece crank. To change out the pinion or sprocket shaft you have to change that wheel/crank half. The shafts are made as part of the crank assembly. The old/shovel head, panhead, knucklehead, sporty cranks were good stuff. Not garbage like twin cam door weights.

3 piece crankshaft, with needle bearings. Wow, That is real old school.

[@nowthisis2stupid]

It's old school, but the beauty of it is in it's absolute simplicity. Harley motors are not high tech, however, they are reliable for this one simple reason. Where most motors are permanently and irreversibly damaged, a Harley motor can be repaired. By design it is almost impossible for a common crank pin motor to throw a connecting rod. You may lose the bearings, or the motor may break a wrist pin, but it won't throw a connecting rod, the modularity of the motor also aides in it's robust and endlessly repairable nature.

Check out Precision balance Company of Indianapolis Indiana ...37 years ago I built my first Harley engine that was an FLH 74 cubic inch and I had Precision balance Company of Indianapolis Indiana spin balance the crankshaft as you have to have your crank Wheels together and zeroed out before you taking there and they actually spin balance the crank with the weight of your rotating assembly your connecting rods pistons pins and clips plus weight of piston rings and print out the individual weight to within a gram of all your parts for future replacement if ever ! And last year at my local shop the owner's son pointed out my old bike and she's still running on my first build ever some 37 years later

Hey Paul, what was the cause of the damage to the crank pin?

[@PaulXchannel]

I think a lot of km or miles.

[@thenewBH]

@@PaulXchannel Given the damage was only on the side of the crank pin that sees load during the power stroke, doubtful it was just mileage. In my experience its detonation that shock loads the rollers and pin on top there and chunks the rollers and pin at that location.

[@zeyadsaud6464]

How the hammering solved the issue, and why?? Good job ; )

[@nowthisis2stupid]

The hammering centered both halves of the Crankshaft on their axis in relation to each other. That's what the dials were measuring, seeing as common crank pin motors do not have a singular statically milled axis, you have to center both halves in respect to each other. It's also a matter of balance.

He's centering it.

I trued HD flywheels for thirty odd years, they need be within .001 inch true and straight to run smoothly. New flywheels could be a pain but stock old ones generally fall back to true fairly easily.
