you must not know much about engine assembly ! = i bet you !

@@ronnieboucherthecrystalcraftsm Hi, Ronnie I am wondering about the comment you just sent me ??? Why would you assume that I don't know much about engine assembly ??? Base upon my positive comment about Paul Xs' display of expertise. Tim

Do you know what pressure at takes to press the pin out and back into cranshaft?

Do you know what pressure at takes to press the pin out and back into cranshaft?

​@@ceasarvinas3129it doesn't look to be a very big press. If 20 ton doesn't work replace the jack with a 40 ton unit

Thanks

Thanks.

Thanks

My experience, it's often a bit of case sealant dripped across.

OK. Thanks.

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

@@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

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

Thanks

Thanks. In future videos.

Not

Ok

Thanks for watching.

Thanks. I only have one centering device. I use it in my workshop.

Thank you very much

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.

Thanks

Thanks. Welding the shaft ???

@@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

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

Weld ur up

What?

Yes

Ok

@@PaulXchannel thanks man, i appreciate it.. 🤝

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.

@@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.

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.

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

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

Thanks

Thanks

Thanks.

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

@@donniebaker5984 Excellent point regarding having records of part weights (pistons, rings, pins, clips) for future replacement.

Thanks

Thanks

You make a case and glue with loctite 638

@@PaulXchannel what you mean like a sleeve you mean

@@officialmysteriousrider6327 yes, sleeve

Heavy crankshaft for rod replacement.

@@PaulXchannel Very simple : off course, need some knowledge, but i just say with this example, how H&D so durability. This crankshaft damage result low oil, not by the way R&D . i love the way connecting rod done, one in one. Very intelligent. And i love the fact crankshaft build in two parts, very intelligent, not oblige buy an entire another one. Sorry my english, school nivel ; )

I don't know but a lot.

Because freedumb!!!

Thanks

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 think a lot of km or miles.

@@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.

Thanks. ukposts.info/have/v-deo/qYB7mWiCrop5x4E.html

the output of my press is 50 tons

Wow!

Made in my workshop.

Dial indicators are available online

I think a balance is needed.

Paul X thanks for the reply..so you did think the vibration coming from unbalanced crank?

My press have 50tons.

@@PaulXchannel Thank you!

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.

Every $10,000 motocross engine of all 2020 to as far back as 1968 japanese dirt bikes all ktm dirt bikes all new maico everything is made exactly like this harley and you need to go to and eye doctor and get new glasses cause you got double double vision and no depth perception 1970 shovel head was a 5 piece crank the evos were 3 piece and this is a twin cam that is a two piece ...those bearing are much bigger than those in a drive shaft as if they were actual needle bearings as you claim they are would not last three hours ....So tell me so everyone else will know and exactly why that front rod and the center of the crank pin failed and the rear female rod and both ends of the crank pin still look brand new ..and if you dont come with the correct answer you are just another flilthy scum bucket harley hater who just wants to put harley out of business to make harder for me to own them just for your spite ;
