Yamaha AT 2 125 Enduro Crankshaft inspection and disassembly

[@douglasmeeker360]

Measurements don't lie. Your preliminary measurements verified that the crank was pinched when checking runout. I really like your in-depth analysis.

[@montana2strokeracer]

Thank you, Doug, I just like to have mostly useless info hanging around. It's good to have when needed though.

[@petermckee1061]

Thanks, Dale. Some enjoyable viewing for a sunny but cold and windy Saturday morning here. Looking forward to the follow up. Cheers. Peter.

[@montana2strokeracer]

Thanks Peter, oh my its winter down under. I really like all the seasons, just not the severe ones hot or cold.

[@mattdomenic4814]

Very comprehensive video Dale, I enjoy learning the process of building up a crank the right way.

[@montana2strokeracer]

Glad it was helpful! Thank you

Mr. Sweger does not cut corners and indeed his work for anyone seeking a bike complete rebuilt - restoration my dear friend and brother is the one to completely trust.

[@montana2strokeracer]

Thanks Ricardo, appreciate your kind words my friend.

Good job brother

[@montana2strokeracer]

Thank you so much 😀

[@davidleland8729]

Good evening Dale. Always enjoy watching you do your thing. You always provide so really good information. I got the TS400 engine back together with the help from your videos. You've been a great help!

[@montana2strokeracer]

Thanks buddy, glad the videos were helpfu.

[@LarryJohnson-tc7xc]

I'm here Dale.

[@retromechanicalengineer]

Still very much the best crankshaft videos on KZbin Dale. You analyse because you have an engineer's mind. Data equals decisions. I just hope that the video you watched where the guy got it wrong, wasn't me! Best wishes, Dean.

[@montana2strokeracer]

Thanks Dean, no sir it was not you. You are doing great work over there. Thanks for hanging out in the shop with me.

[@johnreid2837]

Great tip on the lathe. As always I learn something new every episode .

[@montana2strokeracer]

Thanks John.

[@DC-sh8mr]

True professional. Good job.

[@montana2strokeracer]

I appreciate that!

Hi Dale, when I was much younger, I never dreamed that the ball and roller bearings would go bad just by sitting, well I was wrong, I have seen the damaged bearings. the engineer I was working with told me that it was from electrolysis damage. that really was a wakeup call for me. my last job we had to rotate the large motors in storage once a month to help this problem. now I worry about the motorcycle that I have in storage with a ball and roller bearing crank.

[@montana2strokeracer]

Thanks Rich, never really thought about it, but I can sure see your point. I am sure not an engineer, but I have always heard that sitting is hard on all mechanical things.

[@richb419]

@@montana2strokeracer hi, at 23:10 you commented about an inclusion on the crank pin

[@montana2strokeracer]

Nope, didn't mention inclusion, I said slight wear, no missing material. Once cleaned up it was not noticeable at all same with the rod. The pin, washers, and bearing were replaced with new ones.

[@jamesws3]

Fascinating!! I learn something new with every video you do. Well done!!

[@montana2strokeracer]

Thanks buddy, not sure I will get a video up this week.....too darn hot, 105 today.

[@bryanbaker6767]

and the ball home also plateaus the Ridges that the stones of the hone left in the bore.... The result is the Rings seat much quicker and last longer.... Great Channel..... just recently subscribed

[@montana2strokeracer]

You are right Bryan, they do knock the ridges down a bit, makes for better ring seating as you stated. Welcome to the channel and thanks for hanging out in the shop with me.

[@markaddy53]

great job as always dale crank looks in good shape next video please

[@montana2strokeracer]

Coming soon!

[@josephsawicki9335]

Dale love your new magnifier mount to the ceiling please

[@montana2strokeracer]

It's really not meant to mount that way, however I'm sure it could be. I need it closer to the bench so I can work with small parts, don't think it would reach were I need it mounted up there.

[@MrJanaRobi]

Dale that was very informative thank you .

[@montana2strokeracer]

Thank you!

[@frankdillon6127]

little audio issue maybe on my side, but don't think so .only right side. starts at 17:00 mark in video.

[@montana2strokeracer]

Think I got it fixed on part 2, it's going up now, probably won't be up till almost midnight. Let me know if it's still there.

[@frankdillon6127]

at least im here, lets get to work! LOL

[@cainbeeping8480]

Here

[@cainbeeping8480]

Dale why do we do the honing ?

[@montana2strokeracer]

First, it's to size the piston to the cylinder, then it's called plateau honing to lower the ridges some and for oil retention, ball hones can also chamfer the ports on a two stroke.
