The Truth Is Out There, Ironhead Flywheels Trued Nbr. 105 

Very few people would even try to get it to .001 Nice job, glad to see somebody cares about their work !

that minced surface on the flywheel really just boosts my theory that most Ironhead reliability problems are caused by people not correctly assembling them correctly or within tolerance

That is some outstanding work my friend! You make it look almost do-able even for me but I guess there's a bunch of stuff you can't possibly show in a video. Anyway it's fun watching and I learn a lot too. Thanks!

The techniques you implemented in your video are great. This type of knowledge needs to be preserved so younger generations can have this and do rebuilds the right way.

You would have made a great teacher Gary. I wish I had your patience.

I have yet to watch a video that made this process, this black art, look easy. I am about one C-hair away from reassembling my 1985 Ironhead-- from this very point forward. Thank you for your contribution, investment, to the art of harley mechanics.

I just picked up a truing stand. Set up a shovelhead crank using used parts from my stash to practice with. Your video helped alot. Got it under a thousandth in about an hour. Thanks and keep the videos coming.

I’ve had several Ironhead motors rebuilt since the mid ‘80’s but never saw a mechanic go through the process of truing up a set of wheels. A really nice video to see as I’m getting ready to put a ‘68 XLCH motor back together

Very much enjoyed the lesson. Looking forward to the next one. Thanks

Master at work .

Great video most people doesn't have the patience to do a job like that correctly.👍

Good video , you covered the topic well ........... again

Fine stuff Gary. Thanks!

Ironheads are the best sounding Harley Engine.

best video eye ever watched on truing flywheels. eye completely understand wutz goin on now. thanx boss! u rock gar! 🤘😎🤘

Very nicely done keep up the great work 👍

I always enjoy your videos and learn from them as well, thank you.

Thanks for keepin it real...sometimes they true themselves, other times you fight them for a couple hours or disassemble and start over! Peace..

It's called "pinch & bow". I don't know why people don't indicate both shafts at the same time. It makes seeing the overall picture quicker and easier.

Busy with this issue at the moment, good stuff Gary

Thank you for sharing knowledge.

thanks, I always learn from for videos.

👍😎 love the channel

thanks for the video helps, Tork specs are very helpful

Loved to see how on earth this crank was put one peace. However this helps me to tell my friends at the garage who have Harleys , That most theyr bikes have been banged togeather with a hammer

Cool video... I had no idea that you had to "true" it like that

Greetings From Siberia . As always I hope the two of you are doing well and that the koala Bear build is coming along without too much frustration . Another first class video production from the crew at I.H.C. world headquarters . What happened to the mic guy?, did he slip by and is now protected because he is in the union and got his sag card or did you have to give him a tune-up . This was a very good tutorial of how to do this very important step in the rebuild process .Very good explanation of pinched and bowed so that anyone could understand the process, professor . You are providing a great service to those that want to learn more about their bikes even if they don't do their own work at least they will have a better understanding of the process of different repairs . One of my mentors years ago thought that the nut locks were now unnecessary since the advent of threadlocker , I think Harley did away with them during the end of the Ironhead production run . I know that some people put a tack weld on the nuts but for most people this is unnecessary .I have never heard of anyone having a issue with the nuts coming loose and if they did I would think it would be because of not paying attention to detail on assembly .I know that some people have real issues trying to true flywheels with some aftermarket rods form some manufacturers, but there are some good ones as well .Patience and cleanliness are two key factors when assembling flywheels . I look forward to the next installment of the Koala Kronichles or Down Under Thunder . Take care my Friends . From The North. Siberian Cycles Gary

Súper video .

Great video. I’m a dirtbike rider and need to do some crank truing. Is that crank holding stand you’re using a custom tool? If not, where can you buy those?

😎👍😎

Super ok👍👍

When I've seen this done before Ive always seen the crank pin torqued all the way first and then the alignment done, since as youve shown when you do it in stages it tends to walk out. Is there a benefit to torquing in stages and truing in between each stage or were you doing that for demonstration purposes?

I just finished assembling my flywheels with new s&s rods and crank pin etc. made sure to flip my thrust washers and steak them in the flywheels. Crank pin nuts are at full torque but I have 0.028" end play between the con rod big end boss and the thrust washer measured with a feeler guage. I believe book says 0.006-.010 what am I missing?

I would just like to know because of someone doing the same thing. Is what size of socket you're using for that nut

It's no wonder the old Harleys have so many inherent issues. What a lousy way to make a crank pin, using a thin jam nut to hold it in place rather than a pressed in pin. I guess they wanted it easy to replace the rod quickly. I find lead hammers to work better, they don't bounce off, all the energy is transferred to where you hit it...

Great job brother! Where can I get my hands on that truing stand you have? I balance and true two stroke kit bike cranks and that stand would help tons!!

Could someone please explain how the flywheel doesn’t go right back out of spec as soon and the downforce from the pistons is applied when the engine is running? It just seems like it would easily move.

Good video, thanks. Could you tell me the taper angle on a big twin big end pin ?

So... I hear people say to not split my cases if my tolerances are ok when I check the flywheel still in the cases. (I don't know what tolerances to check or how to do it yet, but I am researching still. You checked the tolerances on the truing stand and I thought I heard you say they looked pretty good.... Yet you took the flywheel apart anyway and found some damage that I thought you said might make them not salvagable. That tells me I should split my cases no matter what, on my 73 sporster engine rebuild. What would your advice be ?? Thanks for taking the time to teach the rest of us.... your efforts are appreciated.

I would want you working myenginr

Anyone know of someone that does this in North Carolina

The first time I hear "Fuck" in one of these machining videos. Of course, it had to come from a machining nerd with a background in Harleys.

I think this manufacturers are wrong They use a threads and nut on crankshaft That hard to material bending technology always loose and the number are running
