amaqzing stuff , ... gota get me some ! thanks !

[@ProjectTimeGarage]

Nice work. Good thinking on the sleeve retainer. I've ran across a couple that had been welded. Those were a mess. Thanks for the shout out!

[@AutomedicGarage]

Anytime, we should team up sometime.

[@ProjectTimeGarage]

@@AutomedicGarage It would likely benefit both channels.

[@OldeCarrGuy]

ProjectTimeGarage sent me over so I figured I'd see what you had to offer!

[@AutomedicGarage]

Thanks for dropping in. We try to do a video or sometimes 2 a week. Thanks again.

[@mickpaton9473]

Thankyou

Had a similar problem with my 1992 Miata. I had my mechanic watch a You Tube tutorial on this very problem on other Miatas, a couple of years ago. I have added probably 10-15 K more miles and still going strong. I now have 239,296 miles on this car and still purrs like a kitten. "Loctite 660" good stuff.

[@AutomedicGarage]

It’s a great product that really surprised me on how strong and durable it is.

[@johncoscia5258]

l used it for a spun main bearing scooter cases aluminum , still good . Research was to see if an accelerant could be used and is it designed for aluminum even though successful but the joint has to be anerobic or no air to cure. It failed , ss thread repair slug for a manifold didn't cure? Not a pro .thanks .

[@bondjovi4595]

Good for aluminum antiques.

[@gabster118]

I used this stuff recently on a shaft to fit a flywheel which was meant to be a press fit and was incorrectly drilled to be a clearance fit. Within about 30 seconds of activator + 660 and slipping the flywheel on it was locked completely solid and hitting the shaft with a hammer wouldn’t budge it. I imagine that stator is never going to come off again with it on the taper.

[@AutomedicGarage]

I opted to not use the activator, I read of instances where it actually lowers the cure strength.

[@tolga1cool]

@@AutomedicGarage Interesting. According to the Datasheet it cures up to double the strength if using the 7471 activator

[@AutomedicGarage]

@@tolga1cool yea I opted to not use the activator cause of possibly needing to remove it. Sad part is the rod bearings are going out now, so we’ll be tearing it back down and throwing in a new factory Yamaha crank.

[@tolga1cool]

@@AutomedicGarage Well.. that sucks. But at least you got every bit out of that engine lol I'm thinking of using this for my motorcycle sprocket which chewed a bit on the shaft and is wobbly now

[@mariusfurtuna9422]

I put this on my car crank to fit the timing sprocket wich had developed some play, even with new parts. Still strong after 5 years and 65k km. But now i have to take it apart once again to change the belt.

[@AutomedicGarage]

Supposedly heat will break it down, but I think it’s around 500 degrees to get it.

[@mariusfurtuna9422]

@@AutomedicGarage True. I see it now in the data sheet of the product. 500 degrees. Thanks! I will reuse it again at assembly.

[@chrisgrocott6148]

what a shame it nice to of seen what was like before you placed back in position

[@victorsabatino2185]

I believe the part you were calling the stator was actually the rotor, since it is attached to and rotates with the crankshaft. The winding portion (with the coils of wire) is the stator, because it remains stationary, and the magnets in the rotor generate electricity in the coils as they spin around it.

[@AutomedicGarage]

No not a rotor, it’s the flywheel portion of the stator. Typically sold as an assembly thus the reason I was saying stator it’s the out portion of the stator also know as the flywheel in motorcycles, atvs and dirt bikes. Could have said flywheel my bad.

[@BigfootYusuf]

I was wondering if this would work on rc car parts! The steel axle shaft inside the gearbox was broken in half, maybe I should try this loctite..

[@harisyoung4110]

Jb weld or araldite epoxy work better for that.

[@slickfixjeff]

Just wondering what you thought about j b weld 2 part epoxy? I have a raptor 350 with the same problem but I've always liked j b weld

[@AutomedicGarage]

Jb weld ain’t got s*** on this loctite 660. It’s worth the money for the peace of mind

[@slickfixjeff]

Wow ! Really. Ok I'm gonna get this stuff then! Very informative video btw! Thank you!

[@slickfixjeff]

Oh yea, has the fix held up still?

[@AutomedicGarage]

@@slickfixjeff yea, but it’s parked now waiting to replace the whole crank, rod bearing started knocking.

[@slickfixjeff]

Put this stuff on a couple days ago....still not set! Do you think it's because it's cold where I live? About 30- 40 degrees, between night and day. Will it eventually set you think? I've tried researching all the data sheets, but it's unclear. Thanks!

[@polypoly7966]

The Henkel video shows using an activator chemical before the 660. You just used it neat from the tube? Still if it worked must be ok.

[@AutomedicGarage]

It can be used either way. I read several analysis on it before hand and I don’t remember why but for some reason I opted not to use it.

[@crazyflyboy30]

I wonder if it's stronger than JB Weld.

[@bearnecessiteespolio5359]

It is. But it only hardens at it best when used in tight spaces which are therefore starved of air/oxygen. It only fully cures when squashed and not next to air (e.g. squashed u det a keyway, or squashed under a sproket/gear with the pulled add on, to block air. Ive heard good things about JB weld too, but maybe for bigger holes? Just been reading up.on this for hours because I have a damaged crankshaft. I'm going for the 660, and the activator. And even if it works it can all be for nothing if you don't tighten the crank bolt enough. I'm using medium threadlocker on the bolt and getting it all torqued up straight away when the 660 is applied.

[@SIMPLEARKANSAN]

How did you clamp the woodruff key while the 660 set?

[@AutomedicGarage]

I didn’t, I put the 660 on them slid the stator on.

[@SIMPLEARKANSAN]

Thanks. I knew you let it sit 24 hours. I guess with the flywheel over the woodruff key and then you pulled flywheel back off to make sure it set?

[@AutomedicGarage]

@@SIMPLEARKANSAN no. The 660 is holding the woodruff key and stator both. They are both being held on with the 660.

[@SIMPLEARKANSAN]

Thanks. I’m just waiting on my activator and I’ll give it a try.

[@SIMPLEARKANSAN]

I let it sit 24 hours and seems solid. Used on a Seadoo two stroke ski. Followed your steps except I used the activator. Cheaper than replacing the crank for sure! Thanks

[@oneoldjimmy1]

How did it hold up?

[@AutomedicGarage]

It’s held up great, crank bearing went out and it’s been parked ever since but was holding fine for a whole year until it broke down.

[@r.shkr.j]

how to remove it from loctite 660 bond in the future?

[@AutomedicGarage]

Heat

[@JBAutomotive794]

In the industrial world, 660 keeps alot of factories going. When a keyway gets boogered up this stuff gets squirted on it like ketchup.

[@AutomedicGarage]

Yep

[@Jeremy-iv9bc]

Has anyone told you that you sound just like Hank Hill?

[@AutomedicGarage]

No, haven’t got that one but I was told I sounded like Blake Shelton

[@toreyboos9094]

Still holding up?

[@AutomedicGarage]

Yes sir, really impressed with the loctite 660.

[@brenthawkins204]

Just doing the keyway should be fine. No need to do the whole stator

[@brenthawkins204]

Wear a frickin helmet already

[@AutomedicGarage]

Brent Hawkins the stator was ate up as stated. Slot was worn pretty bad. Yamaha and Kawasaki was notorious for these keyway problems. Yea my son wears a helmet he was anxious to give it a rip however. Thanks for commenting.

[@johncoscia5258]

I think it's only good for 150 degrees celcius, just saying i know you know .

[@AutomedicGarage]

That’s it heat tolerance. Seeing how it takes 500F+ to remove parts it’s been applied Id is say it’s good to near 500F. It’s held this together for 2+ years now and I know the Miata guys use it on their cranks a lot too. And I did look at the SDS.
